Letterly
Letterly turns spoken words into polished text you can paste, send, or save. You record on your phone, Mac, Windows, or browser, and the app transcribes what you said, then runs it through rewrite styles tuned for emails, meeting recaps, journal entries, or social posts. It sits between a voice memo app and a writing assistant, built for people who think faster out loud than on a keyboard.
Most dictation tools either transcribe or summarize, but rarely both in the same workflow. Letterly layers three jobs: system-wide dictation that pipes text into Gmail, Slack, and Notion; standalone note capture with rewrite prompts; and long-form meeting recording with speaker-separated transcripts up to 90 minutes. The Letterly MCP connector lets Claude, ChatGPT, or Cursor search and rewrite your stored notes without leaving those tools.
Freelancers, managers, and creators who capture ideas while walking or between calls are the clearest fit. A product manager dictating Slack updates, a writer turning walk monologues into blog drafts, or anyone who records lectures and wants labeled speaker notes can stay in one app instead of chaining separate transcription and rewrite tools.
