Questions, plainly answered.

Chat tools answer questions. CoBuilder builds the deliverable. You point it at your work, ask for a vendor follow-up or a draft proposal, and it produces the file using context from your own projects.

Those products showed how much better AI works when it has durable context and real files. CoBuilder brings that architecture to customer follow-ups, proposals, vendor work, and operational documents. It is not a coding tool.

No. CoBuilder is the workspace. The model is one component, and it can change as the underlying technology improves. The value is in how the workspace gives the model durable context about your files, style, and prior decisions.

Professional work already lives on your computer. The desktop app keeps a synced local mirror in ~/CoBuilder/{your-email}/ while the server-side repository remains the source of truth for history, diff, and revert.

CoBuilder uses frontier models from major providers and chooses the best fit for each task. The point is the workspace, not the brand behind a single request.

A credit is a unit of AI work. Short edits use fewer credits. Longer research, drafting, and multi-step work use more. Your dashboard shows the breakdown by task.

A short follow-up email is usually small. A drafted proposal with research is larger. A long research brief or multi-document analysis can use much more. 30,000 credits per month is intended for steady professional use.

CoBuilder warns you at 80%, 95%, and 100%. At 100%, AI work pauses until you top up or your next billing cycle starts.

AI features pause. The app can still open and read your local mirror. You can add 10,000 extra credits for $10, applied to the current month only, or wait for monthly renewal.

No. Each month gets a fresh 30,000 credits. Top-up credits also apply to the current month only.

You get full access to the single CoBuilder plan. A card is required at sign-up through Stripe, but the first charge happens when the 14-day trial ends on day 15. Cancel before then and the card is not charged.

On day 15 of the trial, for the first full month. Your dashboard and the trial T-3 email show the date before the first charge.

Credits cost real money to provide. Asking for a card reduces abuse and lets you keep working when the trial converts.

There is only one plan: $50 per month with 30,000 credits. Top-ups are available for unusually heavy months.

No. Top-ups are always a deliberate action from your dashboard. CoBuilder does not charge you for additional credits unless you ask.

Not in v1. The public plan is monthly at $50.

The source of truth is a per-organization Git repository on CoBuilder servers. That is what enables full version history, diff, and revert. The app keeps a synced local mirror at ~/CoBuilder/{your-email}/ on your machine.

No. Anthropic's and OpenAI's commercial terms prohibit training on customer data. CoBuilder does not train models on your data either.

Only the context your specific task requires, sent for one request at a time. Providers may retain inputs and outputs for up to 30 days for abuse monitoring and safety review under standard commercial terms.

Yes. From your account page you can request an archive of profile data, settings, invoices, and memory CoBuilder has built about your work.

In transit, CoBuilder uses TLS 1.2 minimum and TLS 1.3 when both ends support it. At rest, file bytes in Google Cloud Storage and metadata in Neon Postgres are encrypted with provider-managed AES-256 encryption.

macOS on Apple Silicon, M1 or newer, and Windows 10 or 11 on x64 PCs. Linux and Intel Mac builds are not part of v1.

8 GB RAM minimum, 16 GB recommended, 500 MB free for the app, and broadband internet for sync and AI work.

The desktop installers are not public yet. When they are ready, cobuilder.me/download will carry the real macOS and Windows links.

On Mac, drag the app to Trash. On Windows, use Settings, Apps. Your local mirror stays where it is. Delete your account separately if you also want the server-side copy removed.

Not today. CoBuilder is desktop-first because professional work happens on a desktop. The mobile path is an email link back to your desktop machine.

Email and password, the same pair you used at sign-up. The desktop app remembers you between sessions.

Use the reset link on the sign-in page. CoBuilder emails a one-time link that is valid for an hour. Setting a new password signs you out of other devices.

Yes. Change it from your account page. CoBuilder sends a confirmation to the new address and a heads-up to the old one.

Yes. One account can be used on your own machines. CoBuilder is currently single-user, so account sharing is not supported.

Not today. SSO will arrive alongside team accounts, which are not part of the v1 plan.

Go to Account, Billing, Cancel subscription. You keep access through the end of the current billing period.

No. Cancellation stops the next charge. You keep the access you already paid for through the end of the period.

If you cancel within 7 days of your first paid charge and tell us why, CoBuilder refunds that charge. After that, you keep access through period-end.

Cancellation pauses billing only. Your account remains available for reactivation. To remove stored account data, delete your account explicitly.

Go to Account, Danger zone, Delete account. You must cancel any active subscription first, confirm your email, and re-enter your password. After that, deletion is scheduled with a 30-day reversal window.
