Automated transcription, translation and subtitling platform for audio and video in 54+ languages. Offers pay-as-you-go at $10/hour and subscriptions starting at $25/month (Core plan); a 30-minute free trial is available but no permanent free plan.

Profile

Sonix is an automated transcription and translation platform that converts audio and video into searchable, editable text in dozens of languages, aimed at podcasters, researchers, journalists, marketers and enterprise teams. It runs on hour-based subscription tiers plus a pay-as-you-go option, with every paid plan including AI transcription, AI translation and an in-browser AI workspace for summarizing and editing transcripts, and a 30-minute free trial that needs no credit card.

Who builds it

Sonix is built by Sonix, Inc., a San Francisco-based company focused purely on automated (non-human) transcription and translation. Users upload or import audio/video, get back a time-coded transcript in an online editor, and can translate, summarize or export it into subtitle and document formats.

Core features

  • Automated transcription in 54+ languages and translation into 55+ languages
  • In-browser AI workspace for summarizing, chaptering and querying transcripts, with monthly hours separate from transcription hours
  • Time-coded, searchable transcript editor with speaker labels and an in-editor media player
  • Team collaboration with shared folders and per-workspace storage (25 GB on Core up to 1 TB on Enterprise)
  • REST API available on all paid plans for embedding transcription/translation into other tools
  • SOC 2, HIPAA and GDPR-compliant Enterprise tier with SSO/SAML

Who it's for

Freelancers and occasional users who need a handful of transcripts can use Pay As You Go without a subscription. Regular podcasters, students and small content teams fit the Core or Advanced tiers, while agencies and heavier production teams needing more AI-workspace hours and storage should look at Pro. Enterprises with compliance requirements (HIPAA, GDPR, SOC 2) or many simultaneous users should use the custom Enterprise plan.

Frequently asked questions

What does Sonix cost?

Sonix runs from $10/hour Pay As You Go with no subscription, up to fixed monthly plans: Core at $25/month, Advanced at $50/month and Pro at $80/month (each with a cheaper annual option), plus custom Enterprise pricing. Every subscription plan bundles a set number of transcription/translation hours and AI-workspace hours per month, with overage billed at $10/hour. Check sonix.ai/pricing directly, since exact hours and rates can change.

Is Sonix free?

Not on an ongoing basis — Sonix offers a 30-minute free trial with no credit card required, rather than a permanent free tier. After the trial, using Sonix requires either the $10/hour Pay As You Go option or one of its monthly subscription plans starting at $25/month. This makes Sonix better suited to testing before committing to a paid tier than to indefinite free use.

What languages does Sonix support?

Sonix transcribes audio and video in 54+ languages and translates transcripts into 55+ languages, available across every paid plan rather than gated to higher tiers. This language coverage applies uniformly whether you're on Pay As You Go or a subscription plan, which differs from some competitors that reserve broader language support for their top tiers.

Can I use Sonix transcripts commercially?

Yes — Sonix customers retain control over their own data and transcripts, and the platform is widely used commercially for podcast production, journalism, market research and enterprise workflows. Sonix states that customer audio and transcripts are not used to train its models and are not accessed by staff without express consent. For contractual or compliance-heavy commercial use, the Enterprise tier adds SOC 2, HIPAA and GDPR compliance on top of the standard terms.

Does Sonix have an API?

Yes, Sonix provides a REST API on every paid plan (Core, Advanced, Pro and Enterprise), letting teams submit audio/video for transcription and translation programmatically and pull results into other software. It is not available on the Pay As You Go tier without an active subscription. Enterprise customers get the same API alongside SSO/SAML and a dedicated account manager for larger integrations.

Sonix vs Trint — what's the difference?

Sonix is priced transparently online starting at $25/month (or $10/hour with no subscription) with 54+ languages included at every tier, while Trint sells seat-based Starter and Advanced plans with pricing that generally requires talking to sales or checking its live plan selector rather than a fixed public rate card. Trint leans harder into newsroom collaboration features (shared drives, newsroom-tool integrations) and offers a 7-day free trial instead of a free tier, whereas Sonix offers a 30-minute free trial and a pure pay-as-you-go option for occasional use. Budget-conscious solo users tend to prefer Sonix's transparent hourly/monthly pricing; media organizations wanting deeper editorial workflow integration may prefer Trint.
