just rolled out v3.0 of clearly.md where i deleted some 85,000 lines of code and removed basically every feature. it's primary goal now is simply to be the best* markdown editor and viewer. * i get to define what "best" means. 🤓

As I said a few days ago, t/s it is not just a fixed number at a given context, what matters is the curve. For a 1M context model to be usable, generation and prefill must be fast enough even with very large contexts.

New in API: Comments 💬 Agents can now read, write, and resolve comments on your social content. This unlocks entirely new review and approval flows. Here's a few use cases we're excited about 👇

we built an internal code review tool - fast, ssr, no page jank, opportunistic updates - semantic groups: breaks down a giant diff into logical & ordered groups to review - marks groups that deserve extra human attention

I love this I don't say it because I'm somehow anti-ai, I say this because it's destructive for your life. You're going to have disrupted sleep, you're going to have disrupted relationships, your whole life will be lived between thinking of the next prompt and results of the current one. This ain't it king

Shipped a few more updates to my Mac markdown reader: • App deep links • Mermaid diagrams • Go-to-line with ⌘ L • Typefully integration • Wiki-link suggestions • Draggable tab reordering • Experimental AI chat sidebar • Tasks progress rings in sidebar • Callouts, footnotes, definition lists Even if it's not perfect yet, can't imagine editing my notes and markdown files with anything else at this point.

3/ Recaps We shipped recaps earlier this week, to prep for Opus 4.7. Recaps are short summaries for what an agent did & what's next. Very useful when returning to a long-running session after a few minutes or a few hours.

I built my dream Markdown editor for Mac. → Introducing Cogito (pronounced koh-gee-toh). It started out of frustration: Obsidian is powerful but overwhelming. iA Writer is beautiful but feels built for a different era. Nothing felt right for how I actually write and work now: plain files, lots of folders, agents and scripts editing alongside me. I wanted both: native and beautiful, powerful and calm. So I finally built it. It's fast, keyboard-first, polished, truly native. A Mac app built with power users and developers in mind. This is my love letter to writing and Mac apps. I use it for all my writing now. Free while in beta ✌️

We're making Typefully even more agent-friendly ✨ Your AI tools should be able to do more than just create drafts. They should be able to pull analytics, manage your calendar, schedule posts, and work across your whole team. Now they can 👇
