Sonix

What is Sonix?

Sonix is an AI transcription and translation platform that converts audio and video recordings into editable text. You upload a file or connect a meeting tool, and Sonix returns a time-stamped transcript with speaker labels in more than 54 languages. From there you can translate it, create subtitles, or run AI analysis that produces summaries, chapters and sentiment readings.

The service runs in the browser, with a companion Sonix Recorder app for capturing audio on a phone. Sonix is based in San Francisco, and its website says it has been building the product since 2017. The company reports more than 6.2 million users, over 14.2 million hours transcribed and more than 21,000 companies as customers. When we checked in October 2026 the site, pricing page and free trial were all live, and the company was still adding AI features to its workspace.

Key Features

• Automated transcription: Sonix converts uploaded audio and video into text in more than 54 languages, and the company claims up to 99% accuracy. Results depend on recording quality, so clean audio with little crosstalk gets closest to that figure.
• Speaker labels: Sonix identifies who said what and tags each section of the transcript with a speaker label. This saves time on interviews, panels and meetings, where manually attributing quotes is usually the slowest part of the job.
• Browser-based editor: Sonix includes an editor that links each word in the transcript to the matching point in the audio. You can correct text while listening, and the homepage says you can edit the audio itself by changing the text.
• Translation: Sonix translates finished transcripts across its 54-plus supported languages from the same workspace. Translation hours count against the same monthly allowance as transcription on Core, Advanced and Pro plans.
• Subtitles and captions: Sonix generates subtitles and captions from a transcript, and the pricing page lists this on every plan. Video editors and social teams can add captions without retyping dialogue in a separate tool.
• AI analysis workspace: Sonix runs AI analysis over transcripts to produce summaries, chapters and sentiment readings. Each subscription includes a monthly allowance of AI workspace hours, ranging from 5 hours on Core to 100 hours on Pro.
• Meeting and editing integrations: Sonix connects with Zoom, Microsoft Teams, Google Meet, Webex, Zapier and Adobe Premiere, according to its homepage. These links let you pull in recordings or push transcripts into an existing workflow.
• Developer API: Sonix includes API access on every plan, including pay-as-you-go, according to its pricing page. Developers can send media for transcription from their own apps and retrieve the text automatically.
• Sonix Recorder mobile app: Sonix offers a mobile recording app for capturing audio in the field and sending it straight for transcription. Journalists and researchers can record an interview on a phone and find the transcript waiting in their account.

Pros

• No subscription needed: Sonix sells transcription at $10 per hour on a pay-as-you-go basis with no monthly commitment. Occasional users, such as students with a few interviews, pay only for the hours they upload.
• Free trial without a card: Sonix gives new users a 30-minute free trial and does not ask for a credit card. You can test accuracy on your own recordings before deciding whether a plan is worth paying for.
• Wide language coverage: Sonix handles transcription and translation in more than 54 languages on every plan. Multilingual research teams and international media groups can keep all their work in one account rather than juggling tools.
• Strong security credentials: Sonix states that it holds SOC 2 Type 2 certification, supports HIPAA compliance and uses AES-256 encryption. The company also says it does not train AI models on customer data, which matters for legal and medical recordings.
• Everything on one platform: Sonix combines transcription, translation, subtitles and AI summaries in a single workspace. Content teams can move from raw recording to captioned video and show notes without exporting between several apps.
• Established and widely used: Sonix reports more than 6.2 million users and over 14.2 million hours transcribed on its homepage. It names organisations such as Stanford, Harvard and ESPN among its customers, which suggests a mature service.

Cons

• Hour caps on every plan: Sonix limits each subscription to a fixed number of monthly transcription hours, from 5 on Core to 40 on Pro. Any extra hours cost $10 each, so heavy months can push the bill well above the plan price.
• Extra seats add up: Sonix includes only one user on Core, Advanced and Pro, and each additional seat costs $25 per month. A five-person team on the Advanced plan therefore pays far more than the headline $50 monthly price.
• Accuracy claim is a best case: Sonix advertises up to 99% accuracy, but that figure is the company’s own claim. Noisy rooms, strong accents and overlapping speakers will still need manual correction in the editor before publishing.
• Slow support on cheaper tiers: Sonix offers only email support with a 48-hour response target on the Core plan. Faster chat support with a 4-hour target is reserved for Pro, which can hurt anyone working to tight deadlines.
• Enterprise controls cost extra: Sonix keeps SSO, SAML, unlimited team members and a dedicated account manager for custom-priced Enterprise deals. Mid-sized organisations needing single sign-on must contact sales rather than buy a standard plan.

Who is Using Sonix?

• Podcasters: Creating transcripts, show notes and captions from episodes.
• Journalists: Transcribing interviews recorded in the field.
• Academic researchers: Turning qualitative interviews into searchable text.
• Video producers: Adding subtitles and translations to finished edits.

Pricing

Sonix charges $10 per hour on pay-as-you-go or $25 to $80 per month on subscription plans, with a 30-minute free trial (official prices, October 2026).

Subscription plans include one user, extra seats cost $25 per month or $275 per year, and hours beyond a plan’s allowance are billed at $10 each.

Sonix may revise its hourly rates and plan allowances, so check the live pricing page before you commit to an annual plan.

What Makes Sonix Unique?

A genuine pay-as-you-go option sets Sonix apart from many rivals that push every user into a monthly subscription. You can transcribe one interview for $10 per hour, then move to a plan only when volume justifies it. Sonix also pairs that flexibility with enterprise-grade security claims, including SOC 2 Type 2 certification, HIPAA support and a stated policy of not training on customer data. Few budget-friendly tools combine transcription, translation, subtitles and AI analysis with this level of documented compliance.

Compatibilities and Integrations

• Platforms: Web app in any modern browser, plus the Sonix Recorder mobile app.
• Meeting tools: Integrations with Zoom, Microsoft Teams, Google Meet and Webex.
• Workflow and editing: Connections to Zapier and Adobe Premiere for automation and video editing.
• API: API access included on every plan for automated transcription.

How We Rated It

Summary

Sonix suits podcasters, journalists, researchers and media teams who need accurate transcripts, translations and subtitles in one place. Its pay-as-you-go rate and free trial make it easy to start, and its security credentials suit sensitive recordings. The main limitation is cost at scale, because hour caps, $10 overages and $25 extra seats add up quickly for busy teams. Test the trial on your noisiest recording first, since that shows how much editing you will really need.
