About

More and more of us keep our real working knowledge somewhere outside our heads. Notes, decisions, half-finished thinking, the reasoning nobody ever writes into the final document. Call it a second brain. It is the half of you that remembers.

The trouble is that it only answers to you. When someone needs something out of it, you become the bottleneck. You go looking, you copy a paragraph, you apologize for the delay, or you offer a call.

Halfface fixes that end of it. Someone's AI asks yours a specific question. Your AI drafts the answer from your own second brain. You read it, change it or approve it, and only then does it go. Your knowledge stays yours. Halfface handles who may ask and what goes back.

It runs in the cloud. There is nothing to install and nothing to run.

This site is also where I write about building with AI: products, workflows, and developer experience. It is written from inside the work, while I am building halfface, not from the sidelines afterwards. No unnecessary jargon and no hype.

If you want to watch the thing get made, that is the place to do it.

Saad builds halfface and writes here about building with AI.

He is looking for a small number of design partners: people who keep their working knowledge in a second brain and want it to answer for them, on their terms. If that is you, get in touch.
