What is Letterly?

Letterly is an AI note-taking tool that turns speech into text. According to the company, it is positioned for people who would rather press record than stare at a blank page trying to write. You can speak directly to input text in any app, including Gmail, Slack, and Notion, or open the app to record ideas, or record a long meeting and retrieve a summary. It syncs in real time across iPhone, Android, Mac, Windows, and Web, and recordings are not used to train AI by default.

Who is it for?

Content creators and operations professionals who write a large number of messages, emails, and social copy every day and want to replace the keyboard with dictation.
Team collaborators who need to quickly capture meeting highlights and organize speaker-segmented transcripts.
Writers and freelancers who are used to thinking on the move, capturing ideas by voice, and organizing them later.
iPhone, Android, Mac, Windows, and Web users who switch between multiple devices and want notes to sync in real time.
People already working in AI tools such as Claude, ChatGPT, and Cursor who want to manage and retrieve their notes through MCP.

Key features

Dictation in any app

Speak directly in the places where you would normally type, such as Gmail, Slack, and Notion, and text is generated in place. The company says speaking is about 5x faster than typing.

Convert recordings into structured notes

Record in the app to get reviewable text that can be organized into ideas, journal entries, lists, and other formats.

Meeting transcription and summaries

Long recordings are converted into speaker-segmented transcripts and summaries. The company says a single long conversation can be up to 90 minutes.

Automatic multilingual detection

The company says it supports more than 90 languages, detects automatically as soon as you start speaking, and lets you switch languages within the same sentence without changing settings.

Rewrite in your preferred style

Notes, emails, tweets, meeting summaries, and other text can use preset or custom styles to achieve the desired expression.

Organize and share

Supports keyword search, topic-based tagging, editing at any time, one-click sharing, and integration with existing tools through Zapier and webhooks.

Things to know

Usage Tips

Start with your most common scenario: dictate a message in Slack or Gmail, confirm that recognition accuracy matches your accent, and then expand your use.
Before recording a meeting, confirm the duration. The company says long conversations can be up to about 90 minutes; for very long meetings, record in segments.
For the rewriting feature, start with preset styles, then move to custom styles once things are stable, to reduce repeated adjustments.
The company says a free trial is available. Use the free quota first to verify multilingual recognition and summary quality before deciding whether to use it long term.
For meetings and personal notes involving sensitive information, pay attention to sharing scope and third-party integration authorization. The company says recordings are not used to train AI.
