use case
an ai that codes from your phone
Folk is a personal AI that can actually code — from wherever you happen to be. Text it a feature, a bug, or a quick "can you tweak the landing copy," and folk runs OpenAI's Codex on its own cloud computer: it writes the change, runs it, and (with GitHub connected) opens a pull request. No laptop, no SSH, no terminal. On the train, between meetings, in line for coffee — or, fine, on the toilet. It works in iMessage, Telegram, WhatsApp, and Discord, and it's billed to your own ChatGPT plan.
how folk does it
connect codex + github once
Text folk "connect codex" and authorize with the ChatGPT plan you want to bill to, then connect GitHub the same way. Now folk can read and write your real repos from inside your own private sandbox — no API keys to paste.
describe the change in plain text
Tell folk what you want like you'd tell a teammate: "fix the off-by-one in the date picker," "add a dark-mode toggle," "bump the dep and run the tests." No prompt engineering, no file paths required.
folk writes, runs, and ships it
Folk's Codex agent works on folk's always-on cloud computer — editing files, running commands, checking its work — then opens a GitHub PR and texts you the link. Review on your phone and merge when it's right.
what it looks like
the signup button is the wrong color on mobile, can you fix it and open a pr
On it — cloning the repo and looking at the mobile button styles now.
Found it: the CTA used the desktop color token on small screens. Switched it to the mobile token, ran the build, looks right. PR #482 is up — want me to walk you through the diff?
nah looks good, merge it

자주 묻는 질문
How does folk actually run code?
Every folk account has its own cloud computer — an isolated sandbox that runs 24/7. When you ask for a change, folk runs OpenAI's Codex agent there to edit files, run commands, and test, then reports back over text. Your code never touches other users' environments.
Does it open pull requests on my real repos?
Yes. Connect GitHub once and folk can clone your repositories, make changes on a branch, and open a PR for you to review and merge from your phone. You stay in control of what gets merged.
Which apps can I code from?
Anywhere folk lives: iMessage, Telegram, WhatsApp, and Discord. The coding happens on folk's cloud computer, so the app you text from doesn't matter — it works just as well from the couch as from your desk.
Whose plan does the coding bill to?
Codex coding is billed to your own connected ChatGPT plan — folk never asks for an API key. Folk's $20/mo covers the assistant; the model usage runs on your ChatGPT subscription.
