Overview

Letterly is an AI speech-to-text app that turns spoken thoughts into clear text for messages, notes, meeting recaps, and other everyday writing. Its core promise is to let people record instead of type, then shape the output into the format they need.

The product is presented as a mobile and desktop workflow that works in the app itself and, in some cases, directly inside other apps. The site highlights dictation, rewrites, note organization, live sync across devices, offline recording, and support for long recordings up to 90 minutes.

Core features

Dictation inside other apps

Record speech in the app or dictate directly inside apps such as Gmail, Slack, and Notion. This supports a faster workflow when you want text inserted where you are already working.

Transcription and recaps

Turn recordings into clean text, summaries, and speaker-separated transcripts for longer conversations. The site presents this as useful for meetings, lectures, and interviews.

Rewrite and format text

Use built-in rewrite options to clean up rough thoughts, shorten text, or convert it into formats like messages, emails, and notes. The changelog also shows custom rewrite options and a rewrite options library.

Note organization tools

Search notes by keyword, organize them with tags, and edit them later. The site also mentions merging multiple notes into one on the web.

Cross-device workflow

Work across iPhone, Android, Mac, Windows, and the web with live sync across devices. The site also lists offline recording, audio upload, Apple Watch, widget, shortcuts, and text replacements as built-in options.

Integrations and AI connections

Connect to other tools through Zapier, webhooks, and Letterly MCP. The site says Letterly can connect with Claude, ChatGPT, Cursor, and other AI tools.

Common use cases

Quick messages and replies
Dictate in Gmail, Slack, Notion, Messages, or other text fields when you want to draft faster than typing. Letterly can insert cleaned-up text directly into the app you are already using.
Personal notes and drafting
Capture unstructured thoughts as notes, lists, journals, or drafts, then revisit and rewrite them later. This suits people who want to speak first and organize later.
Meeting and audio recaps
Record meetings, lectures, or interviews and turn them into transcripts, summaries, or speaker-separated notes. The 90-minute recording support makes it suitable for longer sessions.
Formatting text for publishable output
Use the app with rewrite options to shape text for specific formats such as emails, social posts, or follow-up messages. The built-in rewrite library is meant to reduce manual editing after dictation.
AI-assisted workflows
Connect Letterly to AI tools or automation workflows when notes need to flow into another system. The site mentions MCP, Zapier, and webhooks for this kind of handoff.
