• Interactive questions on legal merits, precedent and defendant behavior inside the platform

Compared with Supio

• Strong in the same markets as Supio: United States.

Check before buying: Prices for the law firm platform are not public, so request a quote and ask how fees are split when a case is accepted; the press reported an initial payment plus later fees in 2021. Check your bar's rules on case referrals, fee sharing and client solicitation. Darrow states it does not use personal or privileged data, and its browser add-on Torch is not offered in the EEA, UK or Switzerland.

Harvey is an AI platform for law firms and corporate legal teams that answers legal questions, analyzes large document sets and runs agents for multi-step legal work.

Key functions

• Knowledge answers legal, regulatory and tax questions across practice areas
• Vault stores document sets and analyzes them in bulk with AI
• Agents carry out multi-step legal tasks end to end

Compared with Supio

• Can store data in the EU; Supio states no EU option.
• Names 4 security certificates, Supio 1.
• Strong in the same markets as Supio: United States.

Check before buying: Prices are only available by quote, so clarify the license model and which modules are included. Choose the data region at contract signing, since Harvey offers EU and Switzerland, US and Australia. Check how the platform fits your document management system and confirm the confidentiality commitments against your professional secrecy rules.

Eve Legal sells EveOS, an AI platform for plaintiff law firms in the United States. It covers client intake by voice agent, drafting of demands and discovery, nightly case review, legal research and firm analytics in one system.

Key functions

• AI voice agent answers calls around the clock, runs the intake conversation and scores cases against the firm's own criteria
• Drafting agents for demand letters and discovery responses, trained on the firm's own documents
• Nightly case audit surfaces overlooked injuries, incomplete imaging and claim opportunities

Compared with Supio

• Strong in the same markets as Supio: United States.

Check before buying: Ask for a quote first, since no prices are published. The security page states that data sits in AWS databases in the United States and is encrypted at rest and in transit. We found no subprocessor list, retention terms or statement on model training. Check state bar rules on AI use, call recording consent and, for Illinois or Colorado clients, state AI and privacy laws. Request written security evidence, because the homepage and the security page describe SOC 2 differently.

Filevine is US case management software for law firms, government legal offices and in-house counsel. It covers matters, intake, documents, billing and e-signature, and its LOIS AI adds legal research, drafting and analysis of depositions and medical records.

Key functions

• LOIS Legal Research searches case law and verifies citations
• LOIS for Word reviews and drafts contracts inside Word
• Depo Copilot and Depo Summaries analyze testimony live and afterwards

Compared with Supio

• Offers a free trial; we found none for Supio.
• Strong in the same markets as Supio: United States.

Check before buying: Pricing is custom, so request a quote that separates the platform from LOIS modules. The security page names private AWS, Azure and Google Cloud instances but no regions, and it does not say whether customer data trains AI models, so ask for both in writing. The public data processing agreement lists a subprocessor page. Plan lawyer review of every AI output.

Litera Kira is an AI contract review and due diligence platform from Chicago-based Litera for law firms and corporate legal teams. It extracts key provisions from large contract sets, answers questions across a deal and turns findings into reports.

Key functions

• More than 1,400 lawyer-trained smart fields extract clauses, plus fields you train yourself
• Generative Smart Fields create custom extraction fields from a prompt in any language
• Grid Chat answers questions across all contracts in a review grid with clause citations

Compared with Supio

• Can store data in the EU; Supio states no EU option.
• Strong in the same markets as Supio: United States.

Check before buying: No prices are published, so ask for a quote that covers users, projects and Lito. Pick the AWS hosting region at the start. Generative AI runs on Azure OpenAI in a matching region, but generative requests from Singapore go to Japan East. Litera's master DPA covers UK and EEA customers, and Litera is certified under the EU-U.S. Data Privacy Framework. Check outside counsel guidelines before enabling generative AI per project.

Clearbrief is a Microsoft Word add-in for litigators and other legal writers. It checks the citations and factual claims in a brief against case law and the case record, and links each statement to its source before filing.

Key functions

• Fact-Cite: links statements in a brief to the supporting pages of the record
• Checks citations and quotes from case law and flags unsupported claims
• Tables, timelines and summaries built from evidence documents

Compared with Supio

• Publishes a price (from $300 per user/month); Supio quotes on request.
• Different pricing model: per user instead of contact for pricing.
• Strong in the same markets as Supio: United States.

Check before buying: Check how your matter data is stored: the vendor mentions bring-your-own-storage, but hosting regions, subprocessors and a data processing agreement were not stated on the pages we reviewed in October 2026. For US litigation, confirm court rules on AI use and certification of filings, such as Rule 11, and any local standing orders. Clarify the number of licensed users, since the public price is per user.

DeepJudge is an AI search and workflow platform for law firms and in-house legal teams. It indexes knowledge across document management systems, intranets and email, and lets lawyers search it, ask questions across documents and build AI workflows.

Key functions

• Intent-based search across documents, matters, clients and people
• Negotiation Intelligence finds opposing counsel positions in past agreements
• Questions and answers across several documents in a folder

Compared with Supio

• Headquartered in Switzerland, Supio in United States.
• Strong in the same markets as Supio: United States.

Check before buying: Ask which model and which hosting region your deployment will use, because the vendor lets customers choose and lists no fixed regions. Check the data protection terms under the Swiss FADP and GDPR, as the privacy policy mentions both and the EU-US Data Privacy Framework. Test how ethical-wall rules from your document system map into search results, since confidentiality between matters is central for law firms.

Smokeball is practice management software for law firms from a Chicago based vendor. Solo practitioners and small to mid-sized firms use it for matters, billing, trust accounting and documents, with an AI assistant called Archie working inside each matter.

Key functions

• Archie summarizes matters and documents and suggests next steps
• Archie compares documents and checks them against firm playbooks
• Archie drafts emails in Outlook and text in Word

Compared with Supio

• Strong in the same markets as Supio: United States.

Check before buying: Prices are not published and depend on users, plan, term and add-ons, and Archie AI is an add-on, so ask for a quote that includes it. The pages we checked in October 2026 name AWS as host but no region, and show no DPA or SSO details. Lawyers must review AI output and protect client confidentiality, so check your jurisdiction's rules.
