Chat with 30+ leading AI models in one clean, fast workspace
Move between ChatGPT, Claude, Gemini, Llama and other leading models mid-conversation without leaving the page.
Send one prompt to several models at once and compare their answers to pick the best output.
Turn text prompts into images inside the same workspace, alongside your chat threads.
Draft, rewrite, summarize and refine text with your chosen model in a single continuous conversation.

Managed or self-hosted team AI chat with enterprise-grade governance built in
Connect your own keys to OpenAI, Anthropic, Google Gemini, Mistral, Groq, Cerebras, Amazon Bedrock, Azure and Hugging Face, and switch models per task inside one governed workspace.
Wire up SAML or OIDC against your existing identity provider, map groups to workspace roles, and apply governance policies by department or project.
Every prompt, model call and admin action is written to a queryable, exportable log, while PII detection can flag or redact sensitive strings before a prompt leaves the workspace.
Track spend in real time against your own provider bill, with per-workspace budget alerts and hard caps — and no credits or token bundles sold by Grengin.
