Overview
Casey Newton's annual productivity review centers on an LLM-powered personal wiki built from his writing archive and daily research. The system turns saved articles into linked Markdown pages, timelines, and topic summaries, helping him retrieve context for reporting and find story ideas.
The episode also covers OpenAI's new teen safeguards and reported pause in frontier-model training, followed by the opening of a multistate trial accusing Meta of designing its platforms to keep young users compulsively engaged.
Key Takeaways
Newton's main lesson is that AI becomes more useful when it works against a well-maintained body of personal source material. His wiki began with the full Platformer archive, then expanded through articles he clips each day. The result is a local, searchable record of people, companies, events, and recurring themes in his reporting.
The value is less about asking a chatbot generic questions than about reducing the work of reconstructing a complex story. For a fast-moving case, Newton can open the relevant wiki page, review a generated timeline, and then check its linked original sources before writing or speaking. He treats source verification as mandatory, since the system can still hallucinate.
The wiki also automates a problem that his earlier systems did not solve well: keeping up with long-running topics. Newton previously maintained manual "blips" for subjects such as AI-driven job loss, but the number of categories became hard to manage. The new system creates and updates topic pages as it processes new material, then surfaces active subjects on a daily home page.
He is candid about the tradeoff. The wiki needs ongoing technical attention: pages become unwieldy, scripts fail, and generated writing may need revision. It is useful because it is tailored to his work, not because it is a ready-made product for everyone.
The news segment raises a related question about whether AI companies are moving quickly enough on safety. OpenAI says it has introduced a teen mode with added restrictions and paused training on its latest models while improving security assessments. Ella Markianos argues that safeguards may help but remain vulnerable to evasion, particularly if models have advanced cyber capabilities.
In the Meta trial, several state attorneys general argue that the company knowingly built addictive products for young users and concealed the risks. Meta disputes those claims, saying it has introduced tools to address unhealthy use and has not targeted children.
Practical Steps
- Start with a bounded source collection: your own published work, project notes, client documents, or saved research. Avoid beginning with the entire web.
- Store material in a durable, portable format such as Markdown, with links back to the original documents.
- Build a simple intake habit. Newton clips a selected set of stories after journaling each morning rather than trying to capture everything.
- Ask an LLM to identify entities, concepts, and timelines, then create or update pages for them automatically.
- Keep original-source links on every generated page. Before publishing or speaking, use the wiki to refresh your memory, then confirm claims in the source material.
- Review the system regularly for broken automation, duplicate pages, oversized entries, and writing that needs editing. A personal knowledge base needs upkeep to remain trustworthy.
- For lightweight support, use tools with narrow jobs: a launcher for quick actions, a tagged journal for recall, and video-summary software for work-related material you do not need to watch in full.

Full Transcript
This is Platformer Plus. I'm Casey Newton. The following column was created using a synthetic voice clone made by ElevenLabs. In today's episode, an LLM wiki changed how I work, and everything else I learned about productivity this year. This is a column about AI, my fiancée works at Anthropic, see my full ethics disclosure at platformer.news/ethics. At the beginning of April, the prominent AI researcher Andrej Karpathy tweeted out an idea that was, for a certain kind of productivity nerd, an info hazard. He described the idea this way: Something I'm finding very useful recently: using LLMs to build personal knowledge bases for various topics of research interest. He proceeded to describe his process, adding source documents to a local folder and using an LLM to extract and organize their contents into a Markdown wiki that gets updated as he adds new material. Karpathy's AI-related pronouncements are closely followed online. He is, after all, the person who coined the term vibe coding, and so seemingly within hours, the web had filled up with GitHub repos, YouTube videos, and Substack posts about how to set up an LLM wiki for yourself. I call the idea an info hazard because simply by becoming aware of it, I had ensured that I would devote the next several weeks to building it without having any idea whether it would benefit me at all. As it so happens, it has. Of everything I tried this year to get better at the desk-bound parts of my job, the LLM wiki has easily been the most useful. Like a vintage sports car, it requires a fair degree of maintenance, and there are almost certainly easier ways to create a personal knowledge base. But if you do any sort of work that has made you crave the help of a good research assistant, an LLM wiki might be worth your time. The wiki is the centerpiece for my annual productivity post, where I run down any changes to the way I work that might be interesting to others afflicted by an inexplicable enthusiasm for software. So with that, here's what I'm still doing from last year, what I stopped doing, and what's new. What I'm still doing. Given how often I switch apps, the best test for whether something actually makes me more productive is longevity. Do I install the app on a new machine? Do I renew the subscription when it's time? Can I point to the places where it actually saves me time? Three apps I've recommended in previous years still clear that bar. Raycast, a launcher app that replaces Spotlight, remains my preferred way to navigate a computer. When I press Command Space, the Raycast window instantly materializes and lets me perform actions across most of the apps that I use. I look up words, I do math, I reposition windows, I access my clipboard history, I open websites, and thanks to a paid upgrade, I do tons of simple AI searches in the Raycast window. I use GPT 5.5 Instant here for the high quality to speed ratio. When I'm done, there's no getting lost in a jumble of open tabs or windows. Raycast simply fades back into the background. At this point, I really can't imagine my Mac without it. And in a nice development since last year, it's now available for Windows as well. Capacities, which bills itself as a studio for your mind, is where I keep my daily journal. Each morning, I write a bit about whatever's on my mind. Then I add notable news links from Techmeme to the bottom of my journal and tag them. The result is that when I'm writing a story or preparing for a podcast, I can click a tag like labor and instantly see all the stories I've saved on that subject since I started building this system a couple of years ago. This has been enormously helpful in planning our current podcast mini-series on AI and productivity, since we discuss jobs news on each episode. I used to spend a lot of time digging through databases or running fruitless Google searches in an effort to jog my memory about something I had read. Capacities ensures that it's all just a click away. You could easily do this with any number of apps, but after three years, I still find myself appreciating the simplicity and calm of Capacities. Finally, last year, I mentioned testing an app called Recall that, anticipating the LLM wiki, helps you save and organize content from the web. I found myself using it less for that purpose over the past year, except for one remaining killer use case. Its Chrome extension provides near-instant text summaries of YouTube videos. Over the past year, I've saved myself many hours by dumping podcasts I feel like I should listen to for work into Recall and simply Simply skimming the summaries. What I stopped doing. The two things I stopped doing over the past year are related to each other and to the LLM wiki. For years now, I've been seeking a solution to problems of memory. I've been a tech reporter for almost 16 years, have written a newsletter for almost nine, and have written this newsletter for six. For much of that time, I've been publishing stories and saving research materials in various places. And when a news story comes along that draws on some of that history, I want to find that context as quickly as possible. Last year I talked about how Notion had shipped a feature I'd wanted for years, an agent that could search across the thousands of links I had saved into it over the years. It worked well enough, but I couldn't turn it into a habit. The search feature in the database itself is a simple keyword-based search. A generic search takes place on one of the app's many other surfaces, and the agent often failed to cite its sources without additional prompting. It worked, but it was effortful. Moreover, it only looked backward. I also had a need for a system that would help me organize stories around new concepts and at scale. In Capacities, I took to creating pages I called blips, inspired by Andy Matuschak, where I could gather loose string. For example, in the summer of 2024, I created a blip called AI could create massive job loss and added relevant links to stories about AI and jobs as I encountered them during my daily journaling. For a few months, I felt extremely clever because I created a dynamic object in the template for my daily journal in Capacities that would show me a selection of blips at random. This would regularly remind me of blips that I had forgotten to update and worked better than any system I had previously devised for tracking long-term stories. Ultimately, though, even this system asked a bit too much of me. As the number of blips proliferated, my ability to consistently track stories across all of them waned. This, in turn, made me more reluctant to create new blips. And that's why, when I saw Carpathy's tweet, I sat a little straighter in my chair. What if AI could write and update all those blips for me? The LLM wiki. Really, the most important change in my productivity over the past year is that I make software now. Like seemingly everyone else at the end of last year, I began messing around with Claude Code and have since made a small handful of apps that I really do use all the time. Sometimes I use Glaze, another app from the maker of Raycast; it excels at design and polish. For the LLM wiki, though, I just asked Claude Fable 5 to write me a prompt that would get me a Carpathy-style LLM wiki. I pasted the result into the terminal—I use Ghostty—and before too long, I had created a new folder of Markdown files in Obsidian. One thing that makes the wiki particularly valuable for me is that I first seeded it with my own writing, the entire platformer archive, from which Claude expertly extracted all the various people, companies, and concepts that I have covered here since 2020 and wrote them up in Markdown files that live on my computer. These files can get quite long; my page for Meta runs to more than 12,000 words and contains more than 1,300 links to other pages in the wiki. Day to day, that isn't of much practical use, but I've lost more than one afternoon browsing the archive in the same state of blissed-out curiosity that I browse Wikipedia, remembering old stories and reasoning about how they fit into current events. But I wanted more than a wiki of my own work, and so now each morning after I journal, I save a selection of stories into the wiki via Obsidian's web clipper, which converts them into Markdown. Then a script on my computer reads the stories and figures out where they fit into the wiki. The result is that I now have more than 1,440 wiki pages covering most of what has ever interested me at Platformer, from the content moderation focus of the first few years to my growing interest in child safety and AI progress. The wiki creates detailed timelines that link to original sources, and I can ask it questions using a simple Obsidian plugin named Claudian. How does this make me more productive? I found it highly useful in fast-evolving complex cases like the OpenAI slash Hugging Face agenic breach, where we learned a little more about the story every few days for a matter of weeks. Each day, as I prepared to write, or podcast, or go on someone else's podcast, I would pull up the page and refresh my memory, while also opening up the original sources to make sure nothing I was about to say was hallucinated. Given the real complexity of that story, how exactly did the agent escape? From where? To where? This saved me tons of time. It also gives me useful story ideas, and it does it by automating my old blip system. Each day as it reads, the wiki generates new pages for concepts in the news, like token maxing or youth social media bans or AI copyright. It also updates a home page every morning that highlights stories in the news. This week, spotting the AI and Congress concept in my wiki led me to open the page and see a number of recent stories on the subject. I later pitched it as a podcast segment. All of that is great. What's less great is that the wiki needs more or less constant maintenance. Pages grow too long and need to be compacted. An error in the code means that one process or another stops running and has to be fixed. And Claude's hyper-compressed, borderline unreadable house style—see this tweet and this one—led me to use GPT-5.6 Sol to rewrite much of the system to more closely approximate AP style. It did a great job. It has now been just over a month since I created the wiki, and I find myself looking forward to checking in on it in the morning to see what it has built. On one hand, it seems too specific to me and too clunky for me to confidently recommend. On the other, self-organizing knowledge base strikes me as the teleological end of whatever process began the day I first installed Evernote on my Mac in 2008. That's one reason why I sought out Town CEO Jean-Denis Grèze for an interview last week. One way of thinking about that product, or what it might evolve into, is a kind of Carpathy LLM wiki for work. As ever, the price of using these tools at the bleeding edge is that I arrive everywhere much too early. The payoff is that somehow I'm enjoying myself quite a lot. And now, here's Ella Markianos on what we're following. OpenAI's safety reset. Here's what happened. OpenAI introduced ChatGPT for Teens, a new mode with safeguards designed to protect teen users. The company announced work on the feature last September after they'd been sued by a number of families of teens who had died by suicide following conversations with ChatGPT. OpenAI also announced new measures to protect adult humans, including themselves, from its own products. The company says its new models might have reached a critical level of cybersecurity capabilities, which, among other things, increases the risk their agents will escape containment and hack into other companies, as happened recently. The company said in a blog post that it paused training on its latest generation of models for the past two weeks as it improved security systems. OpenAI will also postpone a planned large training run until it has done more assessments of the system's safety. Here's why we're following. The company's heightened focus on safeguards in the wake of high-profile safety incidents is welcome, even if it is arguably overdue. ChatGPT for Teens will apply safeguards designed to reduce exposure to content that may be harmful or developmentally inappropriate for users under 18. It will build on OpenAI's earlier parental control features that allow caregivers to set quiet hours and get alerts about concerning activity. ChatGPT should not use romantic language, encourage emotional dependence, or imply that it has feelings or consciousness, the company said. The feature takes a similar approach to under-18 accounts created by social media companies in response to child safety concerns. Ask social media companies how that's going. And as with teen accounts, the safeguards can be evaded, as OpenAI said themselves in a blog post a few months ago. Guardrails help, but they're not foolproof and can be bypassed if someone is intentionally trying to get around them. Where I a parent, I'm not sure I'd trust my teen around a model with critical cyber capabilities. So let's hope OpenAI keeps taking the time it needs to ensure it's safe. Here's what people are saying. On X, X OpenAI board member Helen Toner approved of OpenAI's decision to pause training. Really good to see this, she wrote. OpenAI's policy, she wrote, is by far the best way to think about pacing the frontier, not as some fixed amount of time, for example, six-month pause or go 10% slower, but simply making sure that enough time is taken to meet a reasonable safety slash assurance bar. And here's Lindsay Chew on what else we're following. Meta's social media addiction trial opens again. Here's what happened. Four states, California, Colorado, Kentucky, and New Jersey, went up against Meta today in a landmark trial in California over allegations that Meta designed its platforms to be addictive for young users and misled the public about the risks. In opening arguments, Megan O'Neill, deputy attorney general at California's Justice Department, said Meta's business model could be summed up as follows: Hook the users, hold them for as long as they can, harvest their data, hide the truth from the public when making public statements. Meta knew about the addictive effects its platforms had on children's mental health, O'Neill said, despite the company telling Congress and parents that Instagram and Facebook were safe. All the while, it hid the truth, she said. The first witness of the case, whistleblower and a former leader of Facebook's integrity and care team, Arturo Behar, testified that Meta's metric for measuring harm was very narrow and that the company underreports the prevalence of harmful content. Meta lawyer Paul Schmidt argued that the company has not targeted children and said he will present data that shows more than 90% of Facebook users are adults. He conceded Instagram skewed younger, but said the data was similar. Plus, he pointed to past statements from Mark Zuckerberg and Instagram head Adam Mosseri stating the platforms were not designed to be addictive and that research hasn't yet supported the concept of social media addiction. Here's why we're following. Meta has been facing an onslaught of lawsuits over child safety, and it's losing. Just a few days ago, a New Mexico court ordered the company to pay $567 million on top of the initial $375 million in civil penalties to fund the state's abatement plan after the company was deemed to have contributed to a teen mental health crisis. In that trial, the judge called Meta a public nuisance akin to air pollution. Separately, in March, a Los Angeles jury found Meta and Google liable for a young woman's depression and anxiety after she compulsively used social media as a child. This landmark trial could also mean potential changes to Meta's platforms, including a change in recommendation algorithms, parental verification, and the end of autoplay for video content. Here's what people are saying. Kentucky Attorney General Russell Coleman was the latest to compare this trial to the state's success against tobacco companies in the 1990s. AGs are in the perfect position to get this done. We did it with the tobacco settlement in the 1990s. We'll do it again with Meta. Meta, for its part, has consistently denied the allegations. Schmidt painted the company as one that has actually dealt with its issues. There can be no dispute that Meta has recognized people struggle or can struggle with their use of social media and has come up with tools to try and address that. Meta's motto was to move fast and break things, California Attorney General Rob Bonta said. Unfortunately, the thing that was broken here was the mental health of our children.
