DISCO Pricing: What E-Discovery on DISCO Costs
DISCO does not publish a dollar rate, but it does publish the shape of the bill, and that is more than most e-discovery vendors do. As of October 23, 2026, DISCO's own pricing pages say the platform is billed per gigabyte of processed data, that unlimited use of its Cecilia AI is included in that rate, and that there are no separate fees for ingest, processing or users. Its Auto Review first-pass product is the exception: it is billed per document. There is no list price, no stated minimum and no stated free trial, so every real number comes from a written quote. Anyone who tells you what DISCO costs per GB without a source is guessing, and a few pages ranking for this question are doing exactly that.
We do not sell, resell or take referral fees from DISCO, Everlaw or Relativity. This is software evaluation and industry analysis, not legal advice. Everything attributed to a vendor below comes from that vendor's public pages, read on October 23, 2026. Where a figure comes from anyone else, we label it as reported and say how thin it is.
What does DISCO's pricing page actually say?
DISCO has two pages that matter: the general pricing page and the DISCO Platform pricing page. Read together, they make five claims.
First, the unit is processed data. The pricing page says DISCO bills "on processed data," and the platform page says the per-GB hosting fee is "based on the size of your processed data." Processed means after ingest, not the raw size of what you hand over.
Second, AI is not metered. The platform page says "No limits, no tokens" and describes unlimited use of Cecilia AI inside the per-GB rate. That is a real structural difference from vendors that sell AI as credits or per-document actions.
Third, a list of things carries no separate fee. The platform page says there are no separate fees "for ingest, processing, or users." That sentence is worth reading twice, because several third-party pages say the opposite, as covered below.
Fourth, duplicates can be free. When the deduplication option is selected on ingest, the page says you are not charged for duplicate data at a global, family level. That makes your ingest settings a pricing decision, not only a technical one.
Fifth, every page ends the same way: a "Get a quote" button. There is no rate card, no tier table and no calculator.
What is included in the price and what isn't?
DISCO's pricing page lays out a feature grid showing what falls inside the per-GB rate and what does not. Here is our reading of it.
| Item | Billed how, per DISCO's pages |
|---|---|
| Hosting in Active Review and early case assessment | Per-GB rate on processed data |
| Search, filters, search builder and visualization | Included in per-GB rate |
| Cecilia Q&A, single-document Q&A, summaries, definitions | Included in per-GB rate |
| Deposition summaries and transcript review | Included in per-GB rate |
| Automatic timelines | Included in per-GB rate |
| Legal hold (unlimited requests, users and custodians) | Included in per-GB rate |
| Auto Review (AI first-pass review) | Per-document charge |
| Professional services (task-based, matter-based, managed) | Quoted separately; no rates published |
| Ingest, processing and user access | No separate fee, per the platform page |
Two gaps are worth naming. The page does not state a minimum commitment or contract term, so ask for both in writing. And the professional services tiers it lists (self-service, task-based, matter-based and enterprise managed service) have no stated price. If your matter needs a vendor project manager or a complicated ingest, that labor sits outside the per-GB number and should be a separate line in your quote.
DISCO also runs a free tier for a narrow audience. Its pro bono program page offers up to 50 GB of free hosting for eligible pro bono matters, with data above that, and any project management time, charged at what DISCO calls a significantly reduced rate. That is not a trial for commercial work.
How are DISCO's AI features charged?
Split the AI into two products, because DISCO bills them differently.
Cecilia is the question-and-answer layer: ask a question across a case, summarize a document or deposition, get a definition, build a timeline. DISCO prices it as unlimited inside the per-GB rate. If your team likes to interrogate the record repeatedly, this is where the model is most predictable, since the hundredth question costs what the first one did.
Auto Review is the first-pass review product. DISCO describes AI tag suggestions with explanations and review metrics, and claims review speeds of up to 32,000 documents an hour. The pricing page marks Auto Review as "included in per document charge," which means the bill scales with how many documents you send through it.
The speed and accuracy statements on that page are vendor claims. The same page says its precision and recall run 10 to 20 percent above reviewers or the industry average, depending on which line you read. Treat any such comparison as something to test on a sample of your own documents before it enters a budget or a protocol.
For budgeting, this means two variables. Hosting grows with processed gigabytes and how long you keep them. Auto Review grows with documents. A matter with a large, mostly irrelevant collection can be cheap on one and expensive on the other, so model both.
What do buyers report paying?
Very little verifiable data exists, and it is worth being plain about that.
The one third-party figure we found is on an AI Vortex page that reports a $9,458 median annual contract on Vendr's marketplace, from only two purchases, with a range of $3,332 to $15,584. AI Vortex itself calls that too few data points to rely on, and says it does not publish its own estimate. We could not confirm the Vendr numbers independently, so read them as an anecdote about two contracts, not a market rate.
Two other claims circulate and are worth handling carefully.
- "No per-GB hosting charges." The same AI Vortex page says DISCO has no per-GB hosting charges. DISCO's own platform page says the opposite: a clear per-GB pricing structure. When a third-party page contradicts the vendor's published model, go with the vendor page and ask the vendor.
- "Per-user seat fees and a $500 monthly minimum." A competing platform's comparison page makes both claims about DISCO. DISCO's current platform page says there are no separate fees for users, and we found no minimum stated on DISCO's pages. That page is also selling its own seat-based plan, so it has a reason to describe DISCO's model unfavorably. We cannot confirm or refute the minimum, which is why it belongs on your question list.
Older community posts quote hosting and processing rates from years ago. DISCO has changed its model since then, and the platform page now describes a single per-GB structure. Any per-GB rate dated before the current pages describes a model that may no longer exist.
The pattern is the same one we see across the market: published structure, unpublished price, and a handful of unverifiable numbers that circulate as if they were list prices.
How does it compare to Everlaw and Relativity?
All three vendors sell on a data-volume basis and none publishes a rate. The models differ in where the variable cost hides. This table is built only from each vendor's own pricing page, read on October 23, 2026.
| DISCO | Everlaw | RelativityOne (now Relativity aiR) | |
|---|---|---|---|
| Billing unit | Per GB of processed data | Hosted data; rate not published | Committed data volume |
| Published dollar rate | None | None | None |
| Payment options stated | Quote only | Demo or meeting request | Pay as you go, one-year or three-year commitment |
| User licenses | No separate user fees on the platform page; unlimited users on hold | Unlimited user licenses | No per-user fees for the AI capabilities |
| AI charges | Cecilia unlimited in the per-GB rate; Auto Review billed per document | Several AI features marked as credits; single-document use of some needs none | AI capabilities included with the committed data volume |
| Separately licensed extras | Professional services | Public records add-on | Data Breach Response, Translate, Relativity FOIA, Legal Hold |
| Free tier | Up to 50 GB for eligible pro bono matters | Everlaw for Good program for eligible organizations | None stated |
The sources are DISCO's pricing page, Everlaw's pricing page and Relativity's pricing page.
Read the table for structure, not for a winner. DISCO and Relativity both fold AI into the data-volume rate, though DISCO carves out Auto Review. Everlaw meters batch AI with credits, so its unpredictability sits in how often you re-run prompts. Relativity's bill has its own quirks, such as peak-day measurement, which our Relativity pricing breakdown walks through line by line.

How should you get a quote you can compare?
Give every vendor the same matter on paper. Otherwise you are comparing three different projects.
- Peak processed GB and how much you expect to cull after early case assessment.
- Months in active review versus months you must merely retain.
- Review population you would send through AI first-pass, in documents.
- Deduplication setting you plan to use on ingest.
- People involved, including outside reviewers, so any user fees show up.
- Services you want from the vendor: migrations, project management, productions.
Then ask each vendor the same questions in writing.
- What is the per-GB rate, and what exactly counts as billable data?
- Is there a minimum monthly or annual commitment, and what is the term?
- What is the per-document Auto Review charge, and does a re-run count again?
- What happens to the bill when we delete or export data?
- Are there charges for productions, exports or extra training?
- What do the services tiers cost, and who decides when they are needed?
Platform cost is also not independent of the case. Federal Rule of Civil Procedure 26(b)(1) ties the scope of discovery to proportionality, including whether the burden or expense of proposed discovery outweighs its likely benefit. How that applies to a particular matter is a question for the lawyers on it.

FAQ
How much does DISCO cost per GB?
DISCO does not publish a per-GB rate. Its pricing pages say it bills per GB of processed data and direct you to request a quote. Any specific dollar figure you see elsewhere is a reported number or an estimate, so get it in writing from DISCO for your own data volume.
Does DISCO charge per user?
DISCO's platform pricing page says there are no separate fees for ingest, processing or users, and its legal hold section lists unlimited users. A competitor's comparison page claims DISCO charges per-user access fees. Those claims conflict, so ask for the answer in your quote.
Is DISCO cheaper than Relativity?
No published data can answer that. Neither vendor lists a price, and the structures differ: DISCO bills per GB of processed data with Cecilia AI included and Auto Review per document, while Relativity sells a committed data volume with its AI capabilities included. The only fair comparison is two itemized quotes against the same matter profile.
Does DISCO offer a free trial?
We found no free trial for commercial use stated on DISCO's pricing pages. DISCO does offer up to 50 GB of free hosting through its pro bono program for eligible matters, with additional data charged at a reduced rate. Check the program page for eligibility, which is not open to every user.
