DISCO: cost, fit and limits
DISCO is an ediscovery platform made by DISCO that handles collection, review, legal holds and deposition management, with an AI layer called Cecilia for questions, summaries, timelines and automated review. It is used by law firms and corporate legal departments, with separate login portals for the US, Canada and the EU.
What to know first
DISCO prices by the unit that each product consumes, which makes its page easier to read than most. Platform use is per GB processed, Auto Review is per document, and Hold is per GB, with Cecilia AI use stated as unlimited. The dollar amounts sit behind three separate quote forms. The company's speed figures are its own claims, not an independent benchmark.

Who DISCO is best for
Teams that want predictable AI spend
DISCO's pricing page says Cecilia AI use is unlimited at no extra charge for the platform, which removes the worry of a bill that grows with every question asked.
Litigators managing depositions
Deposition Management is a named product with AI summaries, so trial teams can move from transcript to summary without a separate vendor.
Departments that run holds
Hold is priced per GB with unlimited requests, users and custodians, which fits legal operations that issue many notices a year.
Firms that want review help
Four professional services levels run from self-service training to a fully managed ediscovery portfolio, which lets a firm change support as workload moves.

What DISCO does
- Cecilia Q&A
- Reviewers ask plain-language questions about a case or drop in a document and receive answers from the document set, with the home page citing the vendor's own figure of 87 percent time saved on fact questions.
- Auto Review with Tag Tuner
- Generative AI proposes tags with explanations, and Tag Tuner lets a team adjust the criteria, so reviewers can see why a document was called responsive.
- Cecilia Advanced Research
- Described as agentic AI for complex cases and queries, aimed at investigations where a single question needs several rounds of searching across documents. The pricing page lists Cecilia AI use as unlimited on the platform.
- Timelines
- Facts from documents become a legal chronology that can be updated as review continues, saving the manual work of a separate spreadsheet timeline. The pricing page lists search, filters, visual and list views, and ediscovery integration.
- DISCO API
- The home page lists a DISCO API for integrating DISCO with existing systems, which matters when a firm wants matter data to flow into its own workflow tools, and points to developer documentation at developer.csdisco.com.
How DISCO handles your data
DISCO's security page says it is SOC 2 Type 2 and ISO 27001 certified and GDPR compliant, with ISO 27701 and SOC 3 badges. It states hosting on AWS global infrastructure and encryption in transit and at rest, and the home page lists US, Canada and EU login portals without naming storage regions. The page does not state AI training use or retention, and sends buyers to trust.csdisco.com for those answers.
Where DISCO falls short in practice
- Quote forms for every product. Three separate quote links mean a buyer must price the platform, review and hold products one at a time and then add the results together.
- Unaudited speed claims. Figures such as 32,000 documents reviewed per hour and 98 percent faster deposition summaries are vendor numbers and depend heavily on matter type. The pricing page adds a claim of 10 to 20 percent higher precision and recall.
- Region questions deferred. The security page does not name data regions or AI training terms and defers both to a separate trust center, which it links at trust.csdisco.com, so those details are not on the page itself.

Alternatives to DISCO
DISCO: common questions
How does DISCO charge for AI?
The pricing page says Cecilia AI use is unlimited with no extra charge for the platform, which is billed per GB processed. Auto Review is a separate per-document charge, so the two AI features sit on different billing lines, one per GB and one per document.
What is DISCO Auto Review?
Auto Review is generative AI document review that suggests tags with explanations and includes review metrics and collaboration. It is priced per document, apart from the platform, and the Tag Tuner feature lets a team adjust how documents are judged.
Does DISCO have an EU login?
Yes. The home page lists separate login portals for the US, Canada and the EU, at login.csdisco.com, login.csdisco.ca and login.csdisco.eu. It does not state where each portal stores data, and the security page names only AWS global infrastructure for hosting, with encryption in transit and at rest.
Can DISCO manage legal holds?
Yes. DISCO Hold is priced per GB with unlimited requests, users and custodians, one-click in-place preservation, customizable notice and reminder templates, and audit logs. A team can start a hold before any review begins, then move preserved data into the platform.
What security certifications does DISCO state?
The security page says SOC 2 Type 2 and ISO 27001 certified, GDPR compliant, and shows ISO 27701, SOC 2 and SOC 3 badges. It also lists two-factor authentication, single sign-on and expiring passwords. AI training terms are directed to the trust center.
