Basics
Go to Sign up and create a free account — no credit card required. You can start chatting immediately on the Free plan.
Open a new chat and type a message. TextMate AI defaults to Mistral Large, a balanced, general-purpose model with a 262K context window.
Every chat has a model picker. Free accounts can choose between Mistral Large (default) and GPT-OSS 20B (lighter/faster). Five more models — DeepSeek V3.1, GLM 4.7, Llama 3.3 70B, Nemotron 3 Ultra, and Google Gemma 4 31B — are available on Pro. See Which Model Should You Use? for a full breakdown.
TextMate AI uses a rolling 4-hour token window rather than a daily reset: 500,000 tokens per window on Free, 1,000,000 on Pro. See Understanding Usage Limits & Plans for details.
From Settings → Connectors, you can connect Gmail, Google Drive, and Google Calendar so the assistant can act on requests like summarizing your inbox or checking your schedule. See Connecting Google Workspace.
TextMate AI remembers context from earlier conversations (backed by Supabase), so you don't need to re-explain background information every session.
