Letterly

Letterly turns recordings and dictation into text for messages, emails, notes, posts, and meeting recaps. It works inside apps such as Gmail, Slack, and Notion, and can transcribe recordings into speaker-separated transcripts and summaries.

Features include AI rewrites, note search and tags, audio and video uploads, translation into 90+ languages, and live syncing across iPhone, Android, Mac, Windows, and web. The site says recordings can be up to 90 minutes and that user content is not used to train AI.
