A friendly way in for anyone, with real depth underneath when you want it. Here's what's live today — and what's next.
Real capabilities in the app right now — not promises.
Describe what you want — an app, a site, a tool — and your co-founder builds it into real, working files. No syntax, no setup.
A real chat surface: images and mockups render right in the reply, you can peek at the reasoning behind any answer, and ⌘F finds anything in the conversation.
A strategist, a skeptic, a finance head, a designer, and a QA lead — one click reframes the conversation through each. The team you can't afford to hire yet.
Decisions, context, your founder journal — carried across every session. Open a conversation and it greets you with where you left off and what matters next.
Flip one switch and nothing runs a command or touches a file without an Allow/Deny from you, right in the conversation. No answer means no action.
Send a correction while it's working and it picks it up straight away. Prefer speaking? Your Mac's built-in Dictation drops right into the message box.
Everything lives in real files on your machine that you own and can take anywhere. No lock-in, no walled garden.
Sessions survive crashes, and every time you come back you get a plain-English recap of exactly where you left off.
Drag a screenshot in — or paste one — and just say "fix this." It renders in the conversation; point at the problem instead of describing it.
Ask for a mockup and preview it live inside the chat — a page, a chart, a design — before a single file changes.
coFounder nudges you toward one change at a time, flags risks in plain language, and keeps a ledger of what's actually verified done — not just claimed.
Go back to before any change from the project's menu. Your current work is saved first, so going back never loses anything. Works in projects kept in git.
Bring several AI sessions into one meeting, each with its own view, and set the pace of every round. Hear it argued out before you decide.
Select any part of a reply and answer just that. Suggested next steps appear as buttons that fill your message box, and never send on their own.
A free, email-verified account gets you in. We store your account — never your work.
Where we're headed next. (Curated — the short list, not the whole backlog.)
Pair your iPhone or iPad to send, approve and stop work from anywhere, end-to-end encrypted. In testing now.
See your app running as it's built, and share a link in one click to get feedback fast.
Put your app online with your own custom domain — hosting and the fiddly bits handled for you.
A database and sign-in for your app, set up by conversation — no servers to wrangle.
An automatic safety + quality pass that catches the common mistakes before your users ever see them.
Tweak your app by clicking on it — changes write back into the real code you own.
coFounder runs on Claude — and you bring your own Claude subscription, so there's no metered AI bill stacking up in the background. The depth of a real developer toolset, made approachable.
