AI transcription platform

Sonix is the AI transcription platform that delivers up to 99% accuracy at prices that make legal transcription agencies look like highway robbery. With support for 30+ languages and pricing as low as $5/hour on Premium plans, it's become the go-to transcription tool for small and mid-size law firms that can't justify $200+ per hour for traditional court reporting services.

Sonix isn't legal-specific — it's a general transcription platform that legal professionals have adopted heavily because the accuracy-to-price ratio destroys everything else in the market. For depositions, client interviews, recorded statements, and internal meetings, Sonix gets you usable transcripts in minutes instead of days, at a fraction of the cost.

What Sonix Does

Sonix uses AI speech recognition to convert audio and video files into text transcripts. Upload a recording, and you'll get a timestamped, speaker-identified transcript back in minutes — not days. The platform includes a built-in editor where you can review, correct, and annotate directly alongside the audio playback.

Key features for legal use: automated speaker identification (critical for multi-party depositions), custom vocabulary (teach it your case-specific terminology), timestamp-level editing, and export formats including Word, PDF, SRT, and plain text. The 30+ language support makes it valuable for firms handling multilingual matters or immigration cases.

Pricing

Sonix offers two tiers that matter for law firms:

Standard Plan: $10 per hour of audio. Pay-as-you-go, no monthly commitment. Good for firms with sporadic transcription needs — a few depositions or interviews per month.

Premium Plan: $5 per hour of audio plus $22/month base fee. The per-hour rate drops 50%, making this the obvious choice once you're transcribing more than ~4 hours per month. Premium also includes advanced features like custom vocabulary and priority processing.

Compare this to traditional legal transcription services charging $150-$300+ per hour. Even with attorney review time factored in, Sonix cuts transcription costs by 85-95%.

Who It's For

Small and mid-size law firms that currently pay too much for transcription or, worse, don't transcribe recordings because of the cost. Solo practitioners handling their own depositions. Insurance defense firms processing high volumes of recorded statements. Immigration lawyers dealing with multilingual interviews.

The sweet spot is any practice where you're recording conversations that need to become text — and where you can't justify traditional transcription pricing. Sonix is also excellent for internal use: transcribing client intake calls, strategy meetings, and attorney dictation. Anything you're currently typing up manually or paying someone else to type.

What It's Not Good At

Sonix produces draft transcripts, not certified transcripts. For court filings, official depositions of record, or any situation requiring a certified court reporter, Sonix doesn't replace the human. The 99% accuracy claim is for clear, single-speaker audio — real-world legal recordings with crosstalk, poor audio quality, or heavy accents will drop that number.

It's also not a legal-specific tool. There's no case management integration, no automatic exhibit marking, no legal-specific formatting templates. You get a solid transcript that you'll need to format for legal use. And for real-time transcription needs (live court proceedings, real-time deposition feeds), Sonix only handles pre-recorded files.

The Verdict

Sonix owns the best price-to-accuracy ratio in legal transcription. At $5-10 per hour of audio, it eliminates the cost barrier that prevents many firms from transcribing recordings they should be transcribing. The accuracy is genuinely good — not perfect, but good enough that attorney review catches the remaining errors quickly.

This isn't a replacement for certified court reporters on critical proceedings. But for the 80% of legal recordings that need to become searchable, reviewable text? Sonix delivers in minutes at a price point that makes "we'll just listen to the recording again" an inexcusable workflow.

The Bottom Line: Sonix delivers the best price-to-accuracy ratio in legal transcription — at $5-10/hour, there's no excuse for leaving recordings untranscribed.
