How is AI used?

Letterly is an AI tool because it uses AI models for two jobs: turning speech into text, and reshaping that text for you.

Transcription

When you record, an AI speech model converts your audio into accurate text — across 90+ languages, detected automatically. See What languages are supported?

Rewriting

Once you have a transcript, a language model can rewrite it into the format you need — a tidy email, a summary, a post, bullet points — while keeping your meaning. You choose the style. See Rewrite options.
