Harvey AI Alternatives: Seven Legal AI Tools by Firm Size and Security

Harvey sells a firm-wide legal AI platform: agents, document vaults, knowledge search across a firm’s own precedents, and workflow apps for intake, contracts and fact chronologies. Its home page speaks to large firms, mid-size firms and in-house teams, lists a long run of security certifications, and offers no public price. Buyers request a demo and negotiate.

That model suits a firm ready to standardize on one platform. It suits a three-lawyer practice, a research-heavy litigation team or a transactional group that lives in Word less well. The seven alternatives below cover those cases, and each entry says plainly how big a firm the vendor targets, how a buyer gets a price, and what security claims the vendor makes on its own site.

For the broader shortlist, including Harvey itself and Clio’s matter-based AI, see the best AI for lawyers roundup. For how these tools fit into day-to-day practice, How Lawyers Use AI covers the workflows.

Selection notes

Three criteria shaped this list: the firm size each vendor says it serves, from solo practitioners to global legal departments; pricing access, meaning whether a firm can see a price, start a trial or must go through sales; and security certifications the vendor publishes, such as SOC 2 Type II, ISO 27001 and ISO 42001, plus any statement on training models with customer data. Every vendor had to be live and selling under the name used here. Vendor details checked November 9, 2026.

For a firm-wide platform like Harvey

Legora

Task: A collaborative workspace for research, document review, drafting and multi-step workflows, with agents, tabular review, monitors and add-ins for Word and Outlook.

Pricing: Not published. Legora’s site offers a demo booking as its only route.

Data handling: Legora lists SOC 2 Type II, ISO 27001 and ISO 42001, says it operates under GDPR with HIPAA-compliant processes, and states there is no AI training on customer data.

Legora’s product scope, a firm-wide workspace with agents and workflows, is the nearest match to Harvey’s on this list. It pitches law firms and in-house teams across M&A, litigation, banking, tax and insurance work, and names mid-sized firms, smaller in-house teams and private equity as segments. A firm already in a Harvey evaluation can run the same use cases through both and compare on outputs and contract terms.

For research-first teams

CoCounsel Legal (Thomson Reuters)

Task: Research grounded in Westlaw and Practical Law, brief building, and bulk document review.

Pricing: No price on the product page, but it offers a free trial, plan pages segmented for law firms by size, corporate counsel and government, a demo and a sales phone line.

Data handling: SOC 2 and ISO 42001 certified, per Thomson Reuters, which says customer data is never used to train underlying models.

Firm size served runs from small firms to large ones, with separate government and corporate plans. Tabular Analysis can run up to 100 questions across 10,000 documents, which covers much of the large-scale review work firms buy Harvey’s vault for. The research is anchored to Westlaw content, so firms already on Westlaw keep one research source of truth.

Lexis+ with Protégé (LexisNexis)

Task: Research, drafting and analysis inside Lexis+, with Protégé as the AI assistant layer.

Pricing: Customized by organization size, practice needs and subscription. Protégé isn’t sold on its own, per the Protégé page, which also offers a trial.

Data handling: LexisNexis says it never uses customer data to train AI models, encrypts sensitive information, and lets customers control whether firm documents feed AI answers. We couldn’t confirm specific certifications from the Protégé page.

LexisNexis names small firms, large firms, law schools, courts, government agencies and corporate legal departments as users. Lawyers searching for Lexis+ AI will find that the old product URL now redirects to Lexis+ with Protégé.

Vincent by Clio

Task: Cited research, multi-state surveys, contract and deposition analysis, and litigation intelligence on judges, counsel and parties.

Pricing: Not published. The vLex site offers a free trial and a demo.

Data handling: SOC 2 and ISO 27001 certified, per the vLex site. Clio’s pricing page says Vincent runs under zero-retention agreements with model providers and that customer data is never used for training.

Vincent came to Clio with the vLex acquisition in 2025. Clio now sells it as part of its enterprise offer for Am Law firms and corporate legal departments, while smaller firms get Clio Work. Its content library spans more than 100 countries, a point in its favor for firms with cross-border matters, and it supports Spanish-language work.

For solo and small firms that want a published price

Paxton

Task: Legal research, court-formatted drafting, and matter fact tables and timelines.

Pricing: Individual plan $499 per user per month, or $2,999 per user per year, with a 7-day free trial. Enterprise pricing is custom. Both are on Paxton’s pricing page.

Data handling: SOC 2, ISO 27001 and HIPAA compliant, per Paxton, which says client data never trains AI models.

Paxton is the only tool here with a self-serve price, which makes it the practical choice for a solo or small firm that can’t wait on an enterprise sales cycle. The Individual plan connects to Box, Dropbox, OneDrive and SharePoint; Word and Outlook plugins and iManage or NetDocuments connectors are Enterprise features.

For contract-heavy practices

Spellbook

Task: Drafting, reviewing and redlining contracts in Microsoft Word, with playbooks, benchmarks and a multi-document agent.

Pricing: Custom by team size, with a 7-day free trial and longer trials for larger organizations, per Spellbook’s pricing page.

Data handling: SOC 2 Type II compliant, with zero-data-retention agreements so customer data isn’t used for training. Spellbook also cites GDPR and CCPA compliance.

Spellbook serves individual lawyers through to global legal departments, and offers free academic access. Transactional teams that found Harvey’s platform broader than they need can get contract work done without leaving Word.

Luminance

Task: Contract intelligence: portfolio search, negotiation against playbooks, and automated workflows from intake to signature.

Pricing: Not published; Luminance routes buyers to a demo.

Data handling: ISO 27001 certified, with regular SOC 2 Type II examinations and third-party penetration testing, per Luminance. The home page doesn’t address model training.

Luminance targets enterprises, naming legal, procurement, finance, sales, compliance and HR teams. It fits a corporate legal department managing a large contract portfolio better than a law firm.

Firm size, pricing access and certifications compared

For reference, Harvey’s own page lists SOC 2 Type II, ISO 27001, ISO 27701 and ISO 42001, but doesn’t state a training policy on its home page.

Questions to settle before switching

A certification badge says an auditor reviewed controls. It doesn’t answer whether a tool suits a firm’s matters. Before signing with any vendor above, a practice group lead can settle these points in a two-week pilot:

1. Which matters go in. Pick three closed matters with known outcomes and run the same tasks through each shortlisted tool.
2. Where the data lives. Ask for data residency, retention periods and the subprocessor list in writing.
3. Who sees what. Check whether the tool respects existing ethical walls and document management permissions.
4. What it costs at scale. Get the per-seat price at the firm’s real headcount, plus any usage caps or overage charges.
5. How to leave. Confirm export formats and deletion timelines in the contract.

The prompt below turns pilot notes into a comparison a partner can read in five minutes. It contains no client data, so it can run in any assistant.

I am comparing [TOOL A], [TOOL B] and [TOOL C] for a
[NUMBER]-lawyer firm focused on [PRACTICE AREAS].

Here are my pilot notes, with client names removed:
[PASTE NOTES]

Build a table with one row per tool and these columns:
task tested | output quality (1 to 5, with one-line reason) |
citation problems found | time to useful result |
price at [NUMBER] seats | open contract questions.

Then list the three biggest risks for each tool in plain language.
Do not invent any figures; write "not in notes" if missing.

Paralegals often run these pilots day to day; AI for Paralegals covers review steps for that work.

Don’t paste this in

During a pilot, the temptation is to test with a live matter. Don’t, until the vendor’s terms are signed and reviewed. ABA Formal Opinion 512 (July 2024) reminds lawyers that Model Rule 1.6 requires keeping client information confidential unless the client gives informed consent, and that Rules 1.1, 1.4 and 1.5 also apply to generative AI. The State Bar of California’s 2026 practical guidance adds that reasonable efforts mean understanding how a product collects, stores and discloses inputs, not relying on marketing assurances, and that agentic tools with access to email or document systems need tight limits on what they can reach. Test with closed or synthetic matters first.
