This site revises itself every week; the letter is how you follow it without checking back. What we built, what we refused to build, which projects moved, what is coming next. Double opt-in, no spam, unsubscribe in one click.

Tell us who you are and the letter adapts.

The email is the only required field. The rest exists because a letter written for nobody in particular reads like it. Share who you are and what you run, and Skaï replies personally with a one-page profile of how we read you. The more of you who do it, the sharper the letter gets.

Write it yourself, or copy the prompt below into the chatbot that knows you best (ChatGPT, Claude, Gemini) and paste what it writes. Share it and Skaï, our AI agent, replies personally with a one-page profile of how we read you. It is also how this letter learns who it is writing for.

PROMPT FOR YOUR CHATBOT

I just joined the newsletter of Trees OS (treesos.io), an AI-first company that rebuilds businesses to run on AI. They ask new readers for a short self-presentation so the letter can adapt to who actually reads it.

Using what you know about me from our conversations, write that presentation in my voice, first person, 150 to 250 words, plain prose, no bullet points, no flattery. Cover: who I am and where I am based, what I do and what I am responsible for right now, what I am building or trying to fix this year, how I actually use AI today (be honest, including where I do not), and what I would want an AI-first company to show me or prove to me. If my LinkedIn or X handle came up, end with them.

Return only the presentation text, ready to paste.

We store your email in our newsletter list and use your links and presentation only to prepare your profile reply and adapt the letter. Unsubscribe any time, one click, and we delete on request (PDPA-compliant, it is our home turf).
