Letterly: Write by Voice & AI

This is the part that replaces your habit of retyping. Install the dictation keyboard on mobile or the floating bar on desktop, tap the mic in Messages, Gmail, Notion, a support ticket, or a search box, and finished text lands at the cursor. A single dictation can run 15 minutes on Pro, so you can speak a full email instead of one sentence. On iOS you can also rewrite by voice straight from the keyboard: select a line, say "make it shorter," and the text changes in place.

A transcript stays untouched, and each rewrite is saved as a separate version of the same note. The default Magic option cleans rough speech into readable prose. Slightly keeps your wording and tone. Significantly rebuilds the whole thing. Format options go further: List, Email, Journal Entry, Meeting Takeaways, Structured. You can write your own prompts as custom rewrite options, pin three of them under the floating bar on Windows, and set one to run automatically after dictation stops.

Recording inside the app produces a note with a title, a clean transcript, and the original audio attached. Record More lets you keep talking into the same note across sessions, and Merge Notes folds two or three notes into one. Search, tags, and sorting keep a year of thinking retrievable, which is the difference between a voice notepad and an audio graveyard.

Meeting mode records through the microphone and returns a transcript that separates who said what. You can add speaker roles after the recording if you skipped the toggle at the start. A summary rewrite turns the transcript into takeaways, and a 90-minute cap on Pro covers most calls. Records audio from the computer too on Windows, so a call on headphones still gets captured. It doesn't tap the Zoom or Meet audio stream, so everyone needs to be audible in the room.

A custom dictionary forces spellings for client names, product codes, and jargon. Text replacements swap a spoken phrase for a block of stored text: say "my signature" and the whole sign-off appears. Both features run on the free plan, which matters because transcription errors on names are the fastest way to make a dictated email look careless.

Letterly ships an MCP server, so Claude, ChatGPT, Cursor, Perplexity, Gemini CLI, and Codex can search, create, rewrite, and translate your notes without you copying text between tabs. Ask Claude what you decided about pricing last month and it reads your voice notes directly. Setup takes a connection step rather than an API key, which keeps non-developers in the loop.

Pro removes the counters on notes, dictations, and rewrites. Recordings reach 90 minutes, dictations reach 15, and the rewrite list opens up entirely. Multi-speaker, translation, dictionary, text replacements, export, and MCP come with both plans, so paying changes volume rather than access to features.
