Pay once for a platform you keep — not two tools you rent.
It's not raw ChatGPT. It's your key, our brain on top.
Bring Your Own Key doesn't mean we just forward your prompt to the model. Every request runs through the PromptCorrectly brain filter first — a hidden layer of cognitive science that restructures the ask, adds the reasoning scaffold, and folds in your project directions. You pay the AI at cost; the answer comes back sharper than asking the model directly.
Your key bills you directly at the provider's price — cents per answer, no markup from us. €9 unlocks the platform; the AI usage is yours at wholesale.
Cognitive-load structuring, pyramid-first reasoning, chain-of-thought and a self-check pass — applied before the model ever sees your ask.
Your project instructions and reference files ride along on every run, so the output fits your actual work — not a generic chat reply.
QDo I need an API key?
Only the €9 Bring Your Own Key plan needs a key. The Free tier gives you 30 free answers on us when you register — no key required.
QIs there a free plan?
Yes. Anyone gets 3 free answers a day with no account, and 30 free AI calls when you register — usable on the landing brain and inside Studio. A free starter set of the 3,750+ library is open to browse, too.
QHow do project workspaces work?
Create a project, write its instructions (how the AI should work for that project), and add reference files. Those directions are applied automatically on every run — on our free brain and on your own key — so outputs are tuned to your specific work.
QCan I cancel anytime?
Yes — manage or cancel from the billing portal in your dashboard at any time. You keep every canvas, save, and project. First purchase has a 14-day money-back window.
QAre my API keys safe?
Keys live only in your browser. Our server forwards them per request to your provider and never logs or stores them. You can verify in the network tab.
QWhat payment methods do you accept?
Secure card payment via Stripe. Prices are in EUR and billed monthly or yearly (yearly saves ~2 months).
