One API key for hundreds of AI models from every major provider
Six hundred plus models for text, image, video, audio, transcription, embeddings, and reranking behind one OpenAI-compatible API.
Requests are rerouted to another provider on outages or rate limits by default, so you don't write custom retry logic.
The auto-router selects a model and provider per request using live marketplace performance and pricing data.
Track spend, tokens, and usage per model, provider, and team member in one place, including bring-your-own-key usage.
Bring ChatGPT into any web page with a shortcut-driven sidebar and selection menu.
Open an OpenAI-powered chat panel over the page you are browsing using a keyboard shortcut, so you never lose context.
Highlight text to summarise, simplify, translate, check grammar, or change length from a floating toolbar under the selection.
Save your own instructions as reusable prompts and trigger them from the quick menu in one click.
Connect a personal OpenAI key for full control over the account, model choice and usage costs.
