Legal AI is entering its “coding agent” era and Spellbook will be leading the category
Anyone deploying capital leverage to legal AI right now will look like a genius. The more capital, the more genius. But the scores won’t be clear until someone falls over their skis.

I got a local version of Vercel's Sandboxes running on my Mac with Lima. These are Firecracker VMs, so I can run full dev envs in each of them. It's a fun toy for learning about virtualization, and with the HarnessAgent the results from Pi are streaming to the client. Pretty cool
We just shipped 𝙷𝚊𝚛𝚗𝚎𝚜𝚜𝙰𝚐𝚎𝚗𝚝, a unified abstraction to orchestrate and integrate any agent’s “brain” into your app. @aisdk now frees you from both model and agent lock-in. (And it doesn’t just get you portability, it’s also delightful to use ofc!)

It's just a toy to learn how Vercel may be hosting their sandboxes. Link here: github.com/ecumene/vercel-ai…

The future is agents and tools. By tools I mean DeWALT. Anything else is for tourists

A more accurate statement is Canada produces a SpaceX annually 🇨🇦 RAHH!!
NEW: SpaceX ($2.69 trillion) now worth more than Canada ($2.5 trillion).
Community note
The $2.69 trillion for SpaceX is its total stock market value. The $2.5 trillion for Canada is its annual economic output (GDP). These measure different things and cannot be directly compared. investopedia.com/terms/m/market… tradingeconomics.com/canada/gdp

AI memory today is snake oil. When it works it's not magical it's just "neat" - when it doesn't it's catastrophic. Avoid buying it, avoid shipping it, avoid thinking about it until Claude/ChatGPT figure it out then copy what they're doing

10 year old me would have shown this to everyone I know
Gameplay looks great.

Gave Fable 5 the Datadog MCP and pointed it at slow traces. It confirmed basically what I would have and some surprising things I missed. I don’t know if I can use other models again. Just wish I could serve it to customers. Hopefully soon

Some legal AI companies are sponsoring athletes. Others are sponsoring actors. Spellbook is sponsoring lawyers. We’re proud to launch Spellbook’s $1m Legal Fellowship Fund. We're supporting law students who want to work at the intersection of law, systems thinking and technology. My co-founder Daniel knew he wanted to change the practice of law early, but that seemed insurmountable until we found an angel investor. We want to pay it forward to the next generation of legal innovators. Please help us spread the word! Apply here: spellbook.com/fellowship Deadline for Fall 2026: July 15.

AGI. No notes.

Spellbook uses Mongo Atlas Search. Everyone (including me, once) said it won’t scale and we have to switch to XYZ because our load is crazy, but when we have an issue we just add an index and it keeps chugging. Sometimes the naive solution can take you really far

You shouldn’t fine tune before PMF You shouldn’t eval before PMF You shouldn’t use a model router before PMF If you want to tinker, tinker with the product
2024: finetuning is the moat 2025: evals are the moat 2026: model router is the moat Thin viral memes that give non-technical people a sense that a company is doing “real hard AI stuff” A rotating shell game—when one meme loses steam the next one comes in

All GIF pickers have enshittified. The GIFs are mostly NFTs, but also most movie/tv clips have been scrubbed defeating the purpose. Need a new competitor that don't GAF

The line between games and apps are blurring

Plugged photogrammetry into a Unity sample and added a CRT filter, could be a fun way to build photo realistic virtual worlds from scans and get away with it. A little spooky/lonely though.

Get Opus 4.8 to generate some UI from a screenshot. Biggest step up since 4.5->4.6 for me. Code is really solid and more obvious too.

Very stoked about my next adventure. I’ve joined Spellbook, but not as CTO. I’m joining as an Executive IC. It probably means different things to different people. It means I'm here to build and be hands on in every part of the company. I've invested and been advising and getting to know @scottastevenson and the team for more than a year. At some point it became obvious the most useful thing I could do was stop talking about ideas and go work with the team. With AI making code cheap to copy, what's going to be hard to copy is the shape of a company. How a team learns, decides, and ships. That's what I want to work on. It's what I've spent the last three decades learning to do. Why Spellbook? The world has entered into one of the largest investment cycles in decades. Trillions of dollars are being deployed into energy, AI, manufacturing, transportation and the modernization of critical global systems. Despite this, progress still moves at the speed of contracts. Spellbook’s mission is to modernize the $1 trillion transactional legal market so the contract system can keep pace with the global economy. At the same time, every contract ever signed is becoming searchable, comparable, and weaponizable by counterparties, regulators, and plaintiffs' lawyers. You will be attacked. We're hiring. Slight bias toward Canada, but remote-friendly for great talent. DM me.
