STT.ai turns any audio or video into accurate text in seconds. Transcribe recordings, podcasts, lectures, interviews and meetings, generate subtitles, translate, and label who said what — powered by state-of-the-art AI speech recognition in 100+ languages.

★ ACCURATE AI SPEECH TO TEXT
Upload audio or video, paste a link, or record live — STT.ai transcribes it with high accuracy using Whisper-class AI models. Built for long-form audio: lectures, podcasts, interviews and meetings, not just short clips.

★ 100+ LANGUAGES
Transcribe in over 100 languages with automatic language detection. Accents and mixed-language audio are handled cleanly.

★ SUBTITLES & CAPTIONS
Generate ready-to-use subtitles and export SRT or VTT for any video. Edit timing on a subtitle timeline and burn captions onto your footage.

★ TRANSLATE TRANSCRIPTS
Translate your transcript or subtitles into another language in one tap — perfect for reaching a global audience.

★ SPEAKER LABELS
Automatic speaker diarization labels who said what, so multi-person interviews and meetings are easy to read and search.

★ LIVE TRANSCRIPTION
Real-time streaming speech to text as you speak — caption talks, calls and recordings on the fly.

★ AI SUMMARY & CHAT
Get an instant AI summary of any transcript, ask questions and chat with your recording, and pull out topics, action items and sentiment. Turn transcripts into blog posts, show notes, study guides and social posts.

★ EXPORT ANYWHERE
Download your text as TXT, SRT, VTT, JSON, CSV, DOCX or PDF. Copy, share, or send it straight to your tools.

★ PRIVATE & ENCRYPTED
Audio is deleted within 24 hours and never used to train models. Pro plans add client-side AES-256 encryption so only you can read your transcripts.

★ DEVELOPER API & BYOK
A clean REST API and Python/Node SDKs let you transcribe at scale. Bring your own key, self-host, or run a private cloud instance.

★ FREE TO START
Transcribe free every day with a daily allowance, then pay per second only for what you use — no bloated subscription.

Whether you're a student capturing lectures, a journalist transcribing interviews, a podcaster making show notes, or a developer building on speech, STT.ai gives you fast, accurate transcription in one app.
