Sonix
Transcribe audio and video with 99% accuracy in 54+ languages using Sonix
Sonix is a strong pick for legal, healthcare, and enterprise teams that need accurate transcripts plus compliance and structured insights. Its 99% accuracy claim and new conversation modeling are compelling, but the lack of a free tier means casual users should look at Otter.ai instead.

Skip Sonix if you only need occasional, free transcription or real-time live meeting transcription—Sonix offers only a 30-minute trial and no live transcription, so you'd be paying for features you don't use.
Going past your plan’s included transcription hours adds $10/hr per extra hour, which can add up quickly on high-volume projects.
Sonix's pricing ($10/hr pay-as-you-go, $25–$80/mo subscriptions) fits professionals with consistent transcription volume. For occasional users, Otter.ai's free tier or rev.com's pay-per-minute human service may be cheaper. For high-volume enterprise, Sonix's per-hour rates are lower than human transcription but higher than some batch AI APIs like Deepgram or AssemblyAI.

About Sonix
Sonix is an AI-powered transcription platform that turns audio and video into accurate, timestamped text in minutes. Built for professionals in legal, healthcare, media, and enterprise settings, it promises 99% accuracy across 54+ languages. The platform goes beyond basic speech-to-text: it offers speaker diarization, translation into 55+ languages, automated subtitles and captions, and AI analysis that generates summaries, chapters, and sentiment insights. A standout feature is its browser-based editor, where you can edit audio by editing the transcript text—a workflow that saves hours on corrections. The platform also supports collaboration with multi-user permissions, shared folders, and admin controls. For 2026, Sonix introduced Conversation Modeling, which converts recordings into structured data: named speakers, topics, key statements, action items, and metadata. Another new capability, Multi-Transcript Analysis, lets you ask questions across entire folders of transcripts to surface cross-conversation insights. Security is a priority: Sonix is SOC 2 Type 2 certified and HIPAA-compliant, with AES-256 encryption and a zero-training policy on customer data. For healthcare, automatic PHI detection helps protect sensitive patient information. Legal teams can rely on chain-of-custody audit trails. The platform integrates with Zoom, Zapier, Adobe Premiere, and Microsoft Teams, and offers a RESTful API for automated workflows. Compared to other AI transcription tools, Sonix differentiates itself with enterprise-grade security, structured data outputs, and multi-file querying. It’s a paid solution with no free tier—only a 30-minute trial—so it’s best for organizations that prioritize accuracy, compliance, and scalable workflows over casual, occasional use.
Behind the Verdict
Sonix has carved out a niche as the transcription tool for industries where accuracy isn't optional. Its 99% accuracy pledge, backed by SOC 2 Type 2 and HIPAA compliance, makes it a credible choice for law firms, medical practices, and government agencies. The new Conversation Modeling feature—which turns transcripts into structured objects with speakers, topics, and action items—goes beyond what most transcription tools offer, making it easier to audit and act on recorded conversations. Where Sonix really shines is in its workflow integration. The ability to upload documents alongside audio and ask questions across all files is a differentiator. For legal teams reviewing depositions and bodycam footage, or healthcare providers dictating clinical notes with automatic PHI detection, Sonix provides a level of depth that simpler tools like Otter.ai can't match. The browser-based editor that lets you 'edit audio by editing text' is genuinely clever and saves hours when cleaning up transcripts. However, there are trade-offs. Sonix is a paid subscription with no free tier—just a 30-minute trial—so casual users who need occasional transcription won't find it cost-effective. The pricing tiers, while transparent, can add up quickly when you factor in extra seats at $25/mo each. For high-volume teams, the Pro plan at $80/mo includes 40 hours, but additional hours cost $10/hr, which might surprise budget-conscious buyers. Also, while Sonix supports 54+ languages, accuracy can drop with heavy dialects or noisy audio—a caveat the company acknowledges. Real-time transcription for live meetings isn't the core use case; it's designed for pre-recorded files. If you need live captioning, look elsewhere. In comparison to alternatives, Sonix sits above basic transcription tools in
