Providers & API keys

Each API key is stored only on this device, never on the server, so the same key stays with the provider you entered it under. Add as many OpenAI-compatible endpoints as you like — switching between them never overwrites another.

New endpoint

The API key is saved in this browser for this endpoint only. Leave it blank to keep whatever key was already saved here.

Provider & Model

Choose your API provider and the models to use. Star favourites for quick access in the chat toolbar.

Parser model

Documents without a text layer (images, scans, Word, Excel) are sent to the parser model. Leave it on Same as main model and your main model reads them. Set a cheaper vision model to control scan costs.

Soul, Global System Prompt, Memory & Context

These are injected at message 1 of every chat (unless a chat opts out).

Facts about you — injected at message 1 of every chat (unless a chat opts out).

Prompt Library

Save reusable prompt templates. Use variables like {{role}} that prompt for values when applied. One-click to set as global.

New prompt

This Chat Only

When checked, this chat starts fresh without global memory, soul, or global system prompt.

Documents

PDFs with a text layer are extracted locally (free). Images, scans, Word and Excel go to the parser model.

Storage & Usage

Cleanup runs when you sign in. Monthly cost totals are kept even after chats are deleted.
