Sonix is widely known as an automated transcription and subtitling service with broad language support and a developer API. If you're comparing options, it helps to know exactly what an alternative actually gives you — not just a list of buzzwords.
Transkio is built around a simple workflow: upload a file or record directly in your browser, get a clean transcript back, and export subtitles or text in the format you need — with SRT and VTT included free on every plan.
What people evaluating transcription tools usually want
Most people looking at transcription services want three things: an accurate transcript, subtitle files they can actually use, and a workflow that doesn't require reading documentation for an hour before they get their first result.
Beyond the raw transcript, most people also want to clean it up — fix a misheard word, rename a speaker, tighten the punctuation — without exporting the file into a separate editor first.
How Transkio handles it
Upload an audio or video file, or record straight from your browser at the #transcribe page — no separate recording software needed. Transkio supports common audio formats (MP3, WAV, M4A, AAC, OGG, OPUS, FLAC) and video formats (MP4, MOV, WebM, MKV, MPEG, MPG).
Once your transcript is ready, the built-in editor lets you click any line to jump audio playback to that moment, fix text inline, and rename speakers — with that label carried through to every export. Export TXT, SRT, or VTT for free, or unlock DOCX and JSON on the Starter plan and up.
How Transkio compares
Sonix is a well-known name in automated transcription and subtitling, with a reputation for broad language support and developer tooling. Transkio takes a more focused approach: upload-or-record transcription, a transcript editor built for line-by-line cleanup, free SRT/VTT subtitle exports on every plan, and an inline editor for cleaning up the transcript before you export it. If you want the specifics of Sonix's current plans and features, its own site is the accurate source — this page focuses on what Transkio itself offers.

So today, I want to talk to you about the future of our product and how we're reimagining the way teams collaborate. We started three years ago with a simple idea: what if software could just get out of the way and let people focus on the work that matters? Today, I'm excited to show you where that idea has taken us. We're calling this release the biggest step forward since we launched.

We can only speak accurately to our own pricing, so here it is: Transkio's free plan includes a 60-minute trial, 30 minutes per month, file uploads up to 100MB, in-browser recording up to 30 minutes, and free TXT, SRT, VTT exports. Paid plans add features like speaker detection, summaries, and translation.

Can I export SRT or VTT subtitles for free?
Yes. TXT, SRT, and VTT exports (TXT, SRT, VTT) are available on every plan, including the free plan — no upgrade required just to get subtitle files.
Does Transkio offer an API like Sonix?
Not today — Transkio is built around the browser workflow: upload or record, clean up the transcript in the inline editor, and export TXT, SRT, VTT, DOCX, or JSON. If a transcription API is essential to your setup, check Sonix's own site for what it offers.
What audio and video formats can I upload?
Transkio accepts audio files in MP3, WAV, M4A, AAC, OGG, OPUS, and FLAC, and video files in MP4, MOV, WebM, MKV, MPEG, and MPG. You can also record directly in your browser at #transcribe instead of uploading a file.
Can Transkio translate my transcript?
Yes, translation is available on the Pro plan and produces a translated text transcript. Note that translated SRT/VTT subtitle files aren't part of this feature — translation applies to the text transcript itself.
