Shortlist Felo Subtitles when following and translating multilingual video meetings on zoom, google meet, teams, or webex in real time matters most, and Letterly when transcribing and summarizing meetings or interviews with speaker separation matters most.

Felo Subtitles, made by Felo Inc. (Sparticle), is a real-time transcription and translation tool delivered as a Chrome/Edge browser extension plus companion desktop apps for Windows and macOS.

It recognizes speech in roughly 23 languages and translates into about 20 target languages. Captured sessions can be saved as transcripts and exported as text, and the tool offers AI summaries using templates for contexts like sales, learning, and one-on-ones.

Letterly is a voice-to-text application that converts spoken words into clean, structured written text. Aimed at professionals, students, content creators, and anyone who prefers talking to typing, it lets users record speech directly in the app or dictate into other apps, then automatically transcribes the audio. Beyond raw transcription, Letterly applies AI rewriting so a single recording can become an email, a summary, a social post, a task list, a journal entry, or a meeting recap, using preset styles or custom instructions. It automatically detects and transcribes a wide range of languages and can handle mid-sentence language switching. For meetings and interviews, it offers speaker separation and can generate summaries from a recording. The app supports extended recordings, offline and screen-off dictation, quick-record widgets, and live sync across devices, including Apple Watch. It also integrates with external tools via Zapier and webhooks. Letterly states that user data is kept private and not used to train AI models. It runs on iOS, Android, Mac, Windows, and Web.
