Summary

Letterly turns spoken words into text for messages, emails, notes, meeting summaries, journal entries, and social posts. You can dictate inside apps such as Gmail, Slack, and Notion, or upload audio and video for transcription. It handles recordings up to 90 minutes and detects speech in more than 90 languages, including when a speaker changes languages mid-sentence. Choose a preset rewriting style or make custom rewrite options. Letterly can record without an internet connection, and Zapier and webhook integrations can send notes to other apps. Its MCP connects notes with tools including Claude, ChatGPT, Cursor, Perplexity, Gemini CLI, Codex, VS Code, Windsurf, and Claude Code. Letterly says it does not use user words to train AI. Its DPA describes encryption in transit and at rest, access controls, and regular security testing; users can delete recordings and transcriptions in the app. A free plan and seven-day trial are available. Listed PRO in-app purchases range from 19.99 USD per month to 249.99 USD per once.
