CoCounsel Alternatives: 7 Options by Firm Size and Budget

The best CoCounsel alternative depends on why you are leaving, and almost everyone leaves for one of two reasons: the Westlaw bundle or the price. If the bundle is the problem, the options that stand on their own research content are Lexis+ AI, vLex, Midpage and Alexi. If the price is the problem, the short list is the tools that actually publish one: Paxton at $499 per user per month or $2,999 per year, and Midpage, whose pricing page lists a Professional seat at $100 a month (both checked on the vendors' own pages on September 28, 2026). If CoCounsel is too small for what you need rather than too big, the head-on enterprise rivals are Harvey and Legora. That is seven options, sorted by the reason, not by who wrote the list.

We don't sell CoCounsel or any of the seven, and no vendor pays to change what this page says. Featured placements in our directory are labeled and never move a tool up a ranking. Every pricing line below comes from our directory listing data or from the vendor's own pricing page, and where a vendor quotes rather than publishes, we say so instead of guessing.

Why do firms look for a CoCounsel alternative?

CoCounsel started life at Casetext, which Thomson Reuters acquired for $650 million in cash in August 2023. Since then it has been folded into the Westlaw and Practical Law business, and the packaging shows it. As we laid out in CoCounsel pricing, three of the four legal configurations Thomson Reuters sells pair the AI with a content subscription, online pricing is limited to firms of up to 10 attorneys, and there is no published per-seat price for the AI layer itself.

That packaging produces four distinct reasons to look elsewhere:

1. The bundle. You are a Lexis shop, or you want to drop Westlaw entirely, and paying for a second research platform to get an AI assistant makes no sense.
2. The budget. You cannot put a number in next year's plan until a sales rep gives you one, and the number you get is tied to jurisdictions and term length.
3. The scope. Your work is mostly contracts, not research, or your team wants one workspace for drafting, review and research across practice groups.
4. Firm size. A solo attorney and a 400-lawyer firm are shopping in different markets, and CoCounsel's sales motion is built for the middle and top of it.

Each reason leads to a different shortlist. Here is the tree.

The decision tree

• Leaving because of the Westlaw bundle?
  • Already pay for Lexis: Lexis+ AI. Your AI sits on the research content you already license.
  • Want broad and international coverage: vLex, now part of Clio.
  • Want US case law with a citator and no enterprise contract: Midpage.
  • Litigation-heavy and want memo-style research output: Alexi.
• Leaving because of the price?
  • Need a number before you talk to anyone: Paxton or Midpage, both with published rates and self-serve trials.
  • Need to test at zero cost first: vLex (free trial) or Midpage (two-week trial).
• Leaving because CoCounsel doesn't cover enough?
  • Large firm, many practice groups, one platform: Harvey.
  • Collaborative review and research across a team, Stockholm-founded: Legora.
  • Mostly transactional drafting inside Word: step outside research tools and look at the contract review category instead.
• Leaving because of firm size?
  • Solo to 10 attorneys: Paxton or Midpage.
  • Mid-size litigation practice: Alexi or Lexis+ AI.
  • 100+ lawyers with a procurement team: Harvey or Legora.

Which options don't require a Westlaw subscription?

All seven. The question that matters is what each one uses instead, because an AI research assistant is only as good as the law it retrieves.

Lexis+ AI. LexisNexis' generative AI product runs conversational search, drafting and summarization on Lexis content, with citations checked against Shepard's. For a firm already on Lexis, this is the least disruptive swap in the market: the content, the citator and the billing relationship stay the same. Our directory lists it as pricing on request. We compared the two incumbents head to head in Westlaw AI vs Lexis AI.

vLex. vLex's AI assistant, Vincent, draws on a database the company says covers more than a billion documents from over 100 countries. It is now part of Clio, which sells research and practice management together. That matters if you already run your firm on Clio, and it matters more if your matters cross borders. Free trial available; paid pricing on request.

Midpage. Midpage built its own US legal database rather than licensing one, covering case law, statutes and regulations, with an AI citator that labels treatment as negative, caution or neutral and shows the reasoning behind each signal. A citator is the piece people forget when they leave Westlaw. Losing KeyCite without replacing it is how a research workflow quietly gets worse.

Alexi. Alexi, based in Toronto, is litigation-first: research memos, document intelligence and drafting workflows. It was independently evaluated in the 2025 Vals Legal AI Report. Pricing on request.

Paxton, Harvey and Legora also run without a Westlaw subscription, and are covered below under price and scope.

One caution applies to every tool on this list, CoCounsel included. When Stanford RegLab and HAI researchers tested the major research AI products, they found that Lexis+ AI and Ask Practical Law AI produced incorrect information more than 17% of the time, and Westlaw's AI-Assisted Research more than 34% of the time. Better grounding reduces errors. It does not end them. Whatever you switch to, every citation still gets read before it gets filed, and the courts have been making that point with sanctions, which we track in legal AI hallucination sanctions.

Which alternatives publish a real price?

Of the research tools in our directory, most answer the pricing question with a demo form. Two answer it with a number.

Tool	Published price	Trial	Where verified
Paxton	$499 per user per month, or $2,999 per user per year; custom enterprise pricing	7-day free trial	Paxton pricing page, September 28, 2026
Midpage	Professional plan, $100 per seat per month billed monthly; law student plan $25 a month	Two weeks free, no sales call	Midpage pricing page, September 28, 2026
vLex	Paid pricing on request	Free trial available	Directory data
Trellis	Paid plans on request	Free account	Directory data
CoCounsel, Lexis+ AI, Alexi, Harvey, Legora	Pricing on request	Varies	Directory data

The two published prices describe very different products. Paxton is an all-in-one assistant covering research, drafting and document analysis on one plan, and the annual rate works out to about half the monthly one. We did the break-even arithmetic in our Paxton AI review. Midpage is research-centric and priced like a research tool, so the lower number buys a narrower job.

Trellis deserves a mention even though it is not a CoCounsel replacement on its own. It covers state trial court dockets, motions and judge histories, the layer national research databases have historically covered least well, and it has a free account. For a litigation practice, pairing a published-price research tool with Trellis can cover more ground than one bundled seat.

A published price does not make a tool cheaper. It makes it budgetable. A firm that can see the number can run a two-week trial, decide, and put it on a card. A firm that has to wait for a quote is also waiting on term length, jurisdiction bundles and seat minimums, and none of that shows up until the proposal arrives.

Which enterprise platforms compete head-on?

If CoCounsel feels too narrow rather than too expensive, the real competition is the enterprise platforms, and both are sold the same way CoCounsel is: through a demo, with pricing on request.

Harvey is an AI platform for law firms and professional services teams covering research, drafting and document analysis, with agents built for specific practice areas. It is the most common name in large-firm evaluations, and the one CoCounsel is most often compared against. The difference buyers feel first is grounding. CoCounsel's core advantage is Westlaw and Practical Law content, while Harvey sells breadth of workflow. We covered the trade-off in Harvey vs CoCounsel vs Legora, and if Harvey is also on your list for replacement, see Harvey AI alternatives.

Legora, founded in Stockholm as Leya and renamed in 2025, is a collaborative workspace offering agentic research, tabular document review and a Word add-in. Teams that review large document sets together tend to evaluate it for the tabular review alone.

So, is Harvey a CoCounsel alternative? For a large firm, yes, and a direct one. For a five-attorney litigation shop, it is usually the wrong comparison. The procurement process alone assumes a buying committee most small firms do not have.

How do you switch without losing research history?

Switching research platforms is less about the new tool than about what you leave behind. A clean switch has five steps.

1. Find your term end date first. Thomson Reuters sells CoCounsel Legal on one-year, two-year and three-year terms, and multi-year discounts come with multi-year commitments. Your switch date is set by the contract, not by the trial.
2. Move work product out of the tool. Memos, drafts and research summaries that live only inside an AI assistant's history are the easiest thing to lose. Save finished work to your document management system now, matter by matter, while you still have access.
3. Ask the vendor two questions in writing. What can be exported from your history, in what format? And what happens to uploaded documents and prompts after termination? Get the answer from the vendor, not from a sales summary.
4. Run the new tool on closed matters. Re-run research you already know the answer to. You will see the gaps in coverage, citator behavior and output format faster than any demo will show you.
5. Replace the citator on day one. If you are leaving Westlaw, you are leaving KeyCite. Make sure the new platform has its own citation checking, or that you have one alongside it.

The confidentiality side of the switch matters as much as the research side. The State Bar of California's practical guidance on generative AI for lawyers says reasonable efforts to protect client information require more than marketing assurances and may include reviewing a product's terms of use, privacy policy and vendor documentation. That applies to the tool you are leaving and the one you are joining. For a fuller checklist, see how to evaluate legal AI.

Frequently asked questions

What is the best alternative to CoCounsel?

There isn't one best alternative, because firms leave CoCounsel for different reasons. For a Lexis subscriber, Lexis+ AI. For a solo or small firm that wants a published price, Paxton or Midpage. For a large firm that wants a broader platform, Harvey or Legora. Start from the reason you are leaving and use the decision tree above.

Is there a CoCounsel alternative with published pricing?

Yes. Paxton publishes $499 per user per month or $2,999 per user per year, with a 7-day free trial. Midpage publishes a Professional plan at $100 per seat per month with a two-week free trial. Both were checked on the vendors' own pricing pages on September 28, 2026. Most other research assistants, CoCounsel included, quote on request.

Can you use legal AI without Westlaw or Lexis?

Yes. vLex, Midpage, Alexi and Paxton all run on their own or licensed content without a Westlaw or Lexis subscription. What you need to check is coverage for your jurisdictions and whether the tool includes a citator, since that is the feature most often missed after leaving an incumbent platform.

Is Harvey a CoCounsel alternative?

For large firms, yes. Harvey competes directly with CoCounsel for enterprise research, drafting and document analysis, and both are sold through a sales process with no published price. For small firms, Harvey is usually not a practical swap, because its buying process is built for enterprise procurement.
