Notis
AI assistant in WhatsApp, Telegram, Slack and iMessage that completes tasks across 1,000+ apps and MCP servers, billed by usage not tokens
About Notis
Notis is an AI assistant that lives in the messaging apps you already use — WhatsApp, Telegram, iMessage, Slack, email, a desktop app or a CLI — and finishes tasks rather than discussing them. Send a voice note, forward an email, share a photo or mention it in a channel, and it acts across the tools behind it: creating Notion pages and database rows, sending Gmail replies, booking calendar events, filing Linear issues, opening GitHub pull requests, uploading to Dropbox. More than a thousand integrations are one click, another fourteen hundred need no click at all, and it can be extended with any MCP server or CLI tool, which is what separates it from an assistant limited to a fixed connector list. The design decision that stands out is model billing: rather than metering your tokens, Notis can drive the ChatGPT or Claude subscription you already pay for, running your own agent on your Mac while it is awake and falling back to a Cloud Computer when it is not. It never asks for or accepts an API key. Every pay-per-use tool price is published in advance, anything unusually expensive is confirmed before it runs, and the company reports that the average task across all users last week cost nine cents. The CLI tier is free forever.
