A private AI assistant · self-hosted
Your models,
on tap.
FastLab is an AI chat assistant. Ask questions, work with your files and images, search the web and create pictures, all with open AI models that run on FastLab's own computers instead of an outside AI company. It's free to use with an account.
By continuing, you agree to our Terms and Privacy Policy.

Models on our own computers
Every answer comes from open AI models running on hardware we operate. Your conversations are not sent to outside AI companies, and are never used to train models.
Your chats stay with you
Chat history, attachments and generated images are stored in your own browser. On our servers we keep only your account, the memories you allow, and chats you choose to share.
No ads, no tracking
No advertising, no analytics, no tracking cookies, and we never sell your information.
Signing in with Google
You can create a FastLab account and sign in with your Google account instead of a password. When you do, Google shares your name, email address and Google account ID with FastLab. We use them only to create your account, sign you in and show who is signed in.
We don't receive your Google password and don't access your Gmail, Drive, contacts or any other Google data. We never sell this information, use it for ads, or use it to train AI models. You can disconnect Google in Settings at any time. Our Privacy Policy has the details.
For developers
The same models are available through an OpenAI-compatible API at api.fastlab.app: chat completions, responses, images, files and document summaries, authenticated with an API key or an account session.
