Problem
Typing is slow and interrupts the natural flow of thought, making it difficult for people to capture ideas, compose messages, or take notes efficiently. Many professionals and creatives lose valuable time struggling with writing tasks that could be completed much faster through speech, yet existing dictation tools often lack the intelligence to produce polished, usable text.
Solution
Letterly provides an AI-driven speech-to-text platform that converts spoken words into clean, well-structured text ready for any use case. The service works both as a standalone app and as a keyboard extension, enabling users to dictate directly into any application including Gmail, Slack, Notion, and messaging platforms. Beyond basic transcription, Letterly uses AI to rewrite and refine raw dictation into polished messages, organized notes, or structured journal entries, with no limits on recording length or the number of AI rewrites. The platform also handles longer recordings such as meetings, lectures, and interviews, automatically generating speaker-separated transcripts, summaries, and actionable takeaways.
Target Audience
Primary users are busy professionals, students, and creative individuals who prefer speaking over typing and need to quickly capture or compose text across multiple applications and devices.
