Features
From first prompt to production tool-calling — one workspace covers the whole journey.
Configure persona, instructions, temperature, token limits and few-shot training examples — no code, no YAML.
Upload PDFs, Word docs, CSVs and markdown into organized folders. Your assistant answers from your real documents.
Register REST endpoints as tools. The assistant decides when to call them — and asks before any write action.
Route to GPT, Claude, Gemini, Llama and more through OpenRouter. Swap models per assistant with one dropdown.
Send images, audio, video and documents in chat. Vision models analyze screenshots instantly.
Encrypted API keys, hardened admin auth with throttling, session protection and confirmation-gated actions.
How it works
Name your assistant, set its persona and pick a model. Tune temperature and response length to fit the job.
Add Q&A examples, attach knowledge base documents and register the API endpoints it should be able to call.
Talk to it with text, images and files. It calls tools on demand and always asks before write actions.
