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.
AI dictation that turns messy speech into polished, ready-to-send text
Installs as a custom keyboard on iOS and works in WhatsApp, Slack, iMessage, Notes, Notion and anywhere else you can type; matching Mac and web apps keep everything in sync.
Removes filler words, fixes grammar and structures rambling speech into readable paragraphs, bullets, to-do lists and action plans.
Adjusts the register of your text based on the app you are in, shifting between professional LinkedIn style, casual chat and formal business email.
Shorten, expand, fix grammar, emojify or otherwise remix a draft instantly without retyping it.
