About STT.ai
STT.ai is on a mission to make speech-to-text technology accessible to everyone — developers, researchers, journalists, students, and anyone who works with audio.
We believe that the ability to accurately convert speech into text should not be locked behind expensive enterprise contracts or proprietary black boxes. That is why we built STT.ai: a platform that brings the best open-source speech recognition models together in one place, with a simple interface and a fair pricing model.
Open-Source First
Open source is at the core of everything we do. Our platform is built on top of leading open-source AI models including OpenAI Whisper, SpeechBrain, and Vosk. We contribute back to the community by open-sourcing our own models, encryption code, and tools whenever possible.
We believe transparency builds trust. When you use STT.ai, you can inspect the models that power your transcriptions and understand exactly how your data is being handled.
Privacy First
Your audio is your business — not ours. STT.ai offers client-side encrypted storage so that stored transcripts are encrypted with a key only you have. Audio is processed on our GPU and deleted immediately after transcription. We never sell your data, and we never will.
