Is Sonix AI Free in 2026? Sonix Pricing for Legal Work Explained

No, but every new account starts with 30 free transcription minutes — no credit card required. Sonix's own pricing guide notes that is enough to transcribe a 30-minute interview for $0. After that, Pay As You Go costs $10 per audio hour prorated to the second, and subscriptions lower the effective rate to $5.00/hour on Core ($25/month for 5 hours), $2.50/hour on Advanced, and $2.00/hour on Pro. There is no permanent free tier beyond the initial 30 minutes.

Pay As You Go is a flat $10 per audio or video hour, prorated to the second, with no surcharge for noisy audio, three or more speakers, or rush turnaround — Sonix's pricing guide contrasts this with human transcription at $100–150 per audio hour plus modifiers. Subscriptions reduce the effective rate: $5.00/hour on Core, $2.50/hour on Advanced, and $2.00/hour on Pro. A subscription beats pay-as-you-go from 2.5 hours of monthly usage.

Sonix reports 85–98% accuracy depending on audio quality, with marketing materials claiming up to 99%, and every word is editable in the browser editor. For clean interview audio that is workable. For the audio defenders actually face — bodycam with wind and sirens, muffled jail calls, overlapping speakers — expect to spend correction time in the editor. Accuracy on the transcript is only half the issue, though: Sonix has no case layer, so the transcript still has to be manually tied to the report, the footage, and the rest of the discovery.

Sonix can transcribe the audio and video in your discovery, and it includes useful features like automatic speaker labels, timestamps, entity detection, and click-to-redact audio muting. But it is a general transcription platform, not an evidence workspace: there is no case structure, no OCR of scanned police reports alongside the media, no auto-signals flagging report-vs-bodycam inconsistencies, no timeline or party records, and no AI answers cited to the exact second of footage. Defense teams typically use it as a first-mile tool and assemble the case manually.

Evidence Copilot publishes its pricing: Solo at $39/user/month with 15 media-processing hours included, Firm at $99/user/month with 60 hours, and a PD Office tier at $750/attorney/year with 100 hours. Overage is metered and hard-capped at 3x included hours, and every plan includes the full workspace with no feature tiers. New accounts start on a 7-day full-access trial (Firm-level, no card), and there is a 14-day money-back guarantee on every paid plan. Sonix Core is cheaper at $25/month for 5 transcription hours, but it buys transcription only — not the evidence-review workflow.

Sonix offers click-to-redact audio muting at millisecond precision, documented on its law-enforcement resource page — useful for muting sensitive spoken content before a public-records release. It does not offer frame-accurate video redaction (blacking or blurring regions of footage), image redaction, or PDF redaction. Evidence Copilot covers all four media types, keeps originals immutable, treats every redaction as a new derived file, audits every action, and files AI-suggested redaction regions as suggestion cards that always require human review.
