About AudioSRT

Our Mission

AudioSRT exists to make professional-quality subtitle editing accessible to everyone — convert any MP3, MP4, or WAV to SRT, VTT, or Premiere Pro JSON without uploading a single file. Free users get unlimited, browser-based AI transcription — no account, no upload, no cost, ever. Your audio never leaves your device on the free tier, full stop. For creators who need more — faster turnaround, wider language support, AI-powered cleanup — paid plans add cloud transcription and tools on top of that same free foundation.

Why We Built This

The transcription market has long been dominated by a frustrating model: sign up, upload your audio to someone else's servers, pay monthly, hope your data is safe. We built AudioSRT's foundation around a single principle instead: your audio should never leave your device. Using OpenAI's open-source Whisper model, running directly in your browser, we made that possible — no server, no upload, no risk. That's still exactly how the free tier works today.

Since then, we've also built cloud transcription for creators who want it — faster results, broader language coverage, and AI features that need real server-side processing to work well. Both modes are real, both are maintained, and which one you use is entirely your choice.

How AudioSRT Works

AudioSRT is one editor with two ways to transcribe:

• Free — runs entirely in your browser. Unlimited use, no account required, no upload, no file size or duration cap. Privacy-first by architecture, not by policy.
• Starter ($8/mo) — adds cloud AI transcription: 100+ languages, speaker labels, noise removal, filler word removal, silence removal, and AI-generated summaries, on top of the same full editor.

The free tier isn't a stripped-down trial — it's the real product, and it stays that way. The paid tier is there for people who've decided their time is worth paying for.

Start transcribing now — no account needed.

Privacy-First Architecture

Our privacy commitment isn't just a marketing claim — it's baked into the architecture, and it's tier-aware:

• On the free tier, your audio file is read by your browser using the File API and never leaves it. The Whisper AI model runs locally via WebAssembly, on your own CPU. The transcript, the SRT file, the subtitle settings — all generated and stored locally. We collect no analytics on what you transcribe, how long your files are, or what your transcripts contain.
• On paid tiers, audio you choose to transcribe in the cloud is sent only to our transcription provider to generate your transcript, and is not stored permanently by AudioSRT. See our Privacy Policy for the full, current breakdown of what's collected and why.

The Technology

AudioSRT is built on:

• Browser-based AI transcription — an open-source Whisper model, running locally via WebAssembly, for the free tier
• Cloud AI transcription — for speed, accuracy, and broader language coverage on paid plans
• Secure authentication and cloud project sync — so paid users can pick up a project from any device
• A global edge network — for fast page loads and reliable uptime, wherever you are

We keep this list about capabilities, not vendors — the specific providers behind any of this can and do change; what stays constant is the result you get.

Who We Are

AudioSRT is built by Saswat, an independent developer based in India. No VC, no investors, no pressure to grow at any cost.

AudioSRT is funded by its users, through paid plans — which is exactly what keeps the free tier genuinely free: no ads, no selling your data, no catch. If you use the free tier, someone paying for Starter is quietly subsidizing it, and that's a trade we're proud of, not one we hide.
