Letterly is an AI voice note-taker for people who would rather tap record than struggle with writing. You talk, and Letterly turns your speech into clean, structured text shaped for its destination — a message, a note, an email, a journal entry, or a post — instead of handing you a raw transcript full of filler words and false starts.
Letterly works in three ways. First, dictation anywhere: speak inside Gmail, Slack, Notion, or any input field and get polished text right there, which the company notes is roughly five times faster than typing. Second, thought capture: record ideas, journals, and lists in the app and come back to text worth keeping, with no limits on recordings or AI rewrites. Third, meetings and lectures: recordings of up to 90 minutes become speaker-separated transcripts and summaries. The secret ingredient is rewrites — more than 25 ready-made styles, or your own custom ones, reshape the same spoken words into whatever format you need. Letterly auto-detects 90+ languages, even mid-sentence switches, syncs live across iPhone, Android, Mac, Windows, and web, and can be driven from other AI tools like Claude and ChatGPT through MCP. Your recordings are never used to train AI.
Letterly is free to start on every platform, with a paid subscription unlocking the full experience for regular users. It is listed here as Freemium.
With more than 300,000 users and strong app-store ratings, Letterly suits professionals who write all day but think faster out loud — managers sending feedback, creators drafting posts, students capturing lectures. If typing is the bottleneck between an idea and a finished message, Letterly removes it.
