Sonix Pricing: The Verified Numbers (and the Parts Nobody Publishes)

Sonix publishes two rates clearly, and then a lot of structure it doesn't publish. The verified pay-as-you-go rate is $10 per audio hour ($0.167/minute) with no subscription required — a figure corroborated by Sonix's own help docs and its bodycam-analysis page. The Premium tier, reported at $5/hour plus $22 per user per month, comes from a single third-party analysis of Sonix's pricing page (verified October 24, 2025), so treat it as unconfirmed by Sonix itself.

The metering matters as much as the numbers. Sonix bills by media duration — prorated to the second — and its subscription plans bundle transcription, translation, and re-alignment credits, with overage billed beyond those credits at $10/hour ($8/hour for education and nonprofit accounts), according to Sonix's help center. Translation is charged separately at the transcription rate.

What Sonix does not publish anywhere we could verify:

• Dollar amounts for the Core, Advanced, and Pro multi-user subscription tiers — the pricing page describes the structure but omits the figures.
• Volume-discount rates for team plans. Sonix says volume pricing exists; it doesn't quantify it.
• Whether annual commitments carry a discount. Industry norms run 15–20% off with a 12-month lock, but that's a general pattern, not a confirmed Sonix price.
• Enterprise pricing, which is custom-quoted for volumes of 100+ hours per month.

The math gets counterintuitive fast. A competitor's analysis calculated the single-user breakeven between Standard and Premium at 4.4 hours per month — below that, pay-as-you-go wins. But at team scale the per-seat fee can backfire: a five-user team transcribing 20 hours monthly paid $210 on Premium versus $200 on Standard, making Premium's effective rate higher despite its lower hourly rate. That critic's framing is promotional, but the arithmetic is transparent and worth running against your own intake volume.

For a defender staring down a discovery dump — 40 hours of bodycam, jail calls, interrogation footage — that means your bill scales with whatever the prosecutor turns over, not with what you planned to review. One reviewer of transcription tools described Sonix as running "three separate meters at once — seats, overage hours, and translation," producing bills that are "hard to predict." It's a competitor's opinion, but it tracks the structural reality.

Two honest caveats. First, Sonix's $10/hour buys transcription only — no grounded citations into evidence, no redaction, no defense workflow. Second, if you need a workspace where every AI answer cites the exact video second or PDF page and stays flagged for human review, Evidence Copilot publishes flat pricing with no sales wall: Solo at $39/user/month (15 media-processing hours), Firm at $99/user/month (60 hours), and a PD Office tier at $750/attorney/year (100 hours) — with overage hard-capped at 3x included hours so a surprise production can't blow up the bill.

Sonix offers a 30-minute free trial with no credit card required, which is enough to test accuracy on one bodycam file before committing to any tier.

Why Sonix's Hybrid Model Makes Bills Hard to Predict on a Discovery Dump

If you're defending a case with 40 hours of bodycam plus jail calls, the real question isn't Sonix's sticker price — it's how many separate meters are running your bill up at once.

Sonix's structure is a hybrid: a subscription fee layered on top of per-minute charges. The pay-as-you-go Standard plan runs $10/hour ($0.167/min) with no subscription, while Premium charges $5/hour ($0.083/min) plus $22 per user per month, according to an independent pricing analysis. Sonix's own help center confirms that overage beyond subscription credits bills at $10/hour. Translation is charged separately at the transcription rate — one competitor review describes it as "three separate meters running at once — seats, overage hours, and translation," and a bill that scales in ways that are hard to predict. That's a competitor's framing, but the math behind it is transparent.

The breakeven between Standard and Premium for a single user is 4.4 hours per month. Below that, pay-as-you-go wins. Above it, Premium should — except the per-seat fee muddies the picture. A 5-user team transcribing 20 hours a month pays $210/month on Premium versus $200 on Standard, which works out to an effective rate of $0.175/min on Premium versus $0.167/min on Standard. The "cheaper" plan costs more per minute.

At heavier volumes the gap widens in Premium's favor: a 50-hour month runs $500 on Standard versus $272 on Premium. But discovery dumps rarely stop at included credits. Once a subscription's hours are exhausted, overage bills at the standard $10/hour rate — the same as pay-as-you-go, now on top of the subscription you're already paying. A real case with 40 hours of bodycam plus jail calls and interrogation audio blows past included hours fast, and every hour after that is metered.

• Standard: $10/hour, no subscription — simple, but expensive at volume
• Premium: $5/hour plus $22/user/month — cheaper per hour, but the seats add up
• Overage beyond subscription credits: $10/hour standard ($8/hour for education/nonprofit)
• Enterprise: custom pricing for 100+ hours/month

The practical problem for a defense team is that intake is unpredictable. You don't know in advance whether a case means 5 hours of media or 50, and you can't move between plans mid-case without re-running the breakeven math. Pricing that's prorated to the second sounds fair until you're trying to forecast a monthly bill across three meters.

It's worth noting what the $10/hour buys: transcription only. It doesn't include grounded citations into the exact moment of a video, redaction with an audit trail, or defense-specific review workflows — those are the gaps that push defenders toward purpose-built evidence-review tools like Evidence Copilot, which publishes flat pricing (Solo $39/user/mo with 15 hours, Firm $99/user/mo with 60 hours) and hard-caps overage at 3x included hours so a runaway intake can't surprise you.

What $10/Hour Buys You — and What It Doesn't for Criminal Defense

So you've run the math: at $10/hour pay-as-you-go, transcribing a 40-hour bodycam dump costs $400. That number is real — Sonix confirms the rate on its own pages — but it's worth asking what the money actually buys a criminal-defense practice.

What you get is generic transcription. Sonix supports 38+ languages and claims up to 99% accuracy on clear audio, per its bodycam analysis page. But bodycam audio is rarely clear: wind, radio chatter, overlapping voices at a traffic stop. And "99% accurate" is a self-reported figure on ideal input, not a guarantee on your discovery.

The deeper problem is what transcription doesn't do. Calli Schroeder of EPIC put it bluntly in comments on AI bodycam transcription: "An AI transcription or summary may be 98% accurate, but that 2% could completely change who is at fault and what occurred in an encounter." A transcript with a wrong word can flip who said what — and you won't know which word is wrong unless something flags it for review.

Here's what the per-hour rate doesn't cover:

• Speaker diarization QC — renaming Officer 1 vs. Speaker 2 across every segment, and catching where the model merged two voices into one
• Report-vs-bodycam comparison — finding the inconsistency between what the officer wrote and what the camera recorded is review work, not transcription work
• Citations into the exact video second, so a cross-exam question points to a moment a jury can watch
• Redaction for discovery turnover — faces of minors, bystander PII, license plates
• Suppression and Miranda workflows — a transcript doesn't tell you where the stop exceeded its scope or when custody began

The honest framing: Sonix sells words on a page. Finding the 2% that "could completely change who is at fault" is attorney or investigator time, billed on top of the $10/hour — and on a 40-hour production, that review time dwarfs the transcription cost.

This is why Evidence Copilot prices the workspace, not just the transcript: diarized transcripts, auto-signals that compare each new file against earlier evidence in the case, cross-exam drafts tied to quoted sources, and frame-accurate redaction — with Solo at $39/user/mo including 15 media-processing hours, and overage hard-capped so runaway intake can't overbill. Transcription alone gets you a searchable document. Review is where cases are won.

Published Flat Pricing: The Evidence Copilot Comparison

Sonix bills you for every hour of media you feed it. That's fine if all you need is a transcript — but a 40-hour bodycam dump in a felony case means the bill scales with your caseload, not with your subscription.

Sonix's verified pricing (as of October 24, 2025) runs $10/hour pay-as-you-go with no subscription, or Premium at $5/hour plus a $22/user/month subscription fee, according to a third-party pricing analysis. The $10/hour rate is corroborated on Sonix's own bodycam page. Overage beyond subscription credits bills at $10/hour, and enterprise plans use custom pricing.

Run the 40-hour bodycam case through both models. On Sonix Standard, that single case costs $400 in transcription alone. On Premium, it's $200 in media charges plus your seat fee — and if a five-user firm splits the work, the per-seat fees can push Premium's effective rate above Standard's, as one scenario showed ($210 vs. $200/month for the same 20 hours). Sonix's own help docs confirm overage billing beyond included credits, metered to the second.

Evidence Copilot publishes flat pricing with no sales wall, and the same case lands very differently:

• Solo — $39/user/mo: 15 media-processing hours included; the 40-hour case runs overage on 25 hours, metered and hard-capped at 3x included hours.
• Firm — $99/user/mo: 60 hours with priority queue; a 40-hour case fits inside the monthly allowance.
• PD Office — $750/attorney/yr: 100 hours per attorney, which absorbs the case with room to spare.

That 3x hard cap is the structural difference. Runaway intake — a surprise discovery dump the week before a preliminary hearing — cannot produce an unpredictable bill, because overage stops at three times your included hours. Every plan includes the full workspace; there are no feature tiers.

And what's included goes well beyond transcription. Sonix's $10/hour buys you a transcript. Evidence Copilot's plans include diarized transcripts with word-level timestamps, OCR for scanned police reports and photo exhibits, an AI evidence agent whose every answer cites the exact second of video or page of PDF, frame-accurate video and audio redaction for discovery turnover, and agent playbooks for suppression motion prep and Miranda timelines — with every AI output marked pending human review.

For a solo defender, the honest math is this: Sonix charges per hour of audio and stops there. Evidence Copilot charges a flat monthly rate and includes the review workspace around the transcript — the part you actually bill hours against.

How to Price Your Transcription Stack Before Your Next Case

Before you commit to any transcription tool, price it the way you'd work a case: against your actual discovery volume, not the vendor's demo numbers. A tool that looks cheap at two hours a month can quietly become your third-largest expense by the time a felony file hits.

Start with your own media tally. Pull last month's intake and count the hours across bodycam, interrogation footage, 911 audio, and jail calls. That number drives everything else, because transcription pricing is metered by media duration — billed to the second, per Sonix's own pricing documentation — so your bill scales directly with what the state hands you.

Then run the breakeven math before you sign anything with a per-seat fee. Sonix's model is a hybrid: pay-as-you-go at $10/hour, or Premium at $5/hour plus a $22/user/month subscription, per a detailed pricing breakdown. The single-user breakeven between those two options is 4.4 hours per month. But per-seat fees punish mixed-usage teams: one worked example showed a five-user team at 20 hours/month paying $210 on Premium versus $200 on pay-as-you-go — the "cheaper" plan actually cost more.

Third, check what happens at overage. Sonix bills beyond included subscription credits at $10/hour standard, according to its help center — uncapped, so a discovery dump can spike your bill. Ask any vendor the same question: is overage metered, and is there a ceiling? For comparison, Evidence Copilot publishes flat pricing (Solo $39/user/month with 15 hours; Firm $99 with 60; PD Office $750/attorney/yr with 100) and hard-caps overage at 3x included hours, so runaway intake can't overbill you.

Finally, verify the tool covers the review workflow, not just the transcript. A generic transcription service hands you text and stops there. Ask:

• Does every answer cite the exact video second or PDF page it came from?
• Can you redact video, audio, and PDFs without touching the originals?
• Does it surface report-vs-bodycam inconsistencies automatically, before you think to ask?
• Is there an audit trail you can defend when opposing counsel asks how the exhibit was made?

That last point matters more than price. As Calli Schroeder of EPIC put it in commentary on AI transcription, a transcript that's 98% accurate still has a 2% that "could completely change who is at fault" — which is why every AI output should be marked for human review, never treated as the record.

Run these four checks and the pricing page becomes honest arithmetic instead of a sales pitch.
