Gotham vs CoCounsel, side by side

What to compare	Gotham	CoCounsel
What it is	A legal operating system: research, drafting, review and filing in one workspace.	Agentic legal AI from Thomson Reuters: Deep Research, Brief Builder, Workspaces, a Drafting Agent in Word and Tabular Analysis.
Who uses it	Law firms of every size, from chambers to large multi-office firms, and in-house legal teams. Built India first, for US, UK and cross-border work too.

Indian law	Built in: 365 million Indian legal documents: the Supreme Court, all 25 High Courts, tribunals and regulators, in 22 scheduled languages. Search by SCC, AIR or neutral citation.	Not published. Thomson Reuters sells CoCounsel in India, but its India pages name Westlaw and Practical Law content, not Indian sources.
US and UK law	US and UK case law and legislation, plus official court, legislation, regulator and tax sources from 90+ countries and territories. Pick the countries for each question.	Westlaw and Practical Law, with KeyCite and Key Numbers. More than 650 attorney-editors write Practical Law.
Agents and bulk review	Gotham AI answers with citations to the paragraph. An agentic citator shows how later judgments treated each point of a case. Deep Research with a plan you approve. Tabular Review across a whole data room, and contract review against your firm's playbook.	Deep Research with a check that each cited authority supports the point, and Tabular Analysis of up to 10,000 documents and 100 questions.
Drafting and filing	Drafting in court formats, redlines and a Word add-in, on Gotham Pro. Matters, chronologies, case tracking by CNR, a hearing diary, eSign and e-stamp in the same workspace.	A Drafting Agent in Word and Brief Builder for US litigators. Court-format drafting, e-stamping or eSign for India are not described.
Integrations	Word add-in, Google Drive and SharePoint import, and integrations on Gotham Pro.	Word, Outlook and Teams; iManage, SharePoint, Box and HighQ; NetDocuments in Canada; a connector for Claude.
Citator	An agentic citator built on a legal ontology: treatment point by point (followed, distinguished, doubted, overruled, referred to a larger bench), with the passage, and bench strength applied.	KeyCite, Westlaw's citator, for US law, and Deep Research Verify to check that a cited authority supports the point. Indian coverage is not published.
Security	SOC 2 Type II and ISO 27001. Data stored in your own country. Never used to train AI. SSO, SAML and SCIM.	Its product page says SOC 2 and ISO 42001; a December 2025 Thomson Reuters post says SOC 2 and ISO 27001. No training on your data.
Data location	Stored in your own country, India for Indian customers.	Not published. Thomson Reuters asks you to contact your representative.
Pricing	Junior for one lawyer: ₹499 a month or ₹3,999 a year plus GST in India; $9 a month or $79 a year elsewhere. Gotham Pro: priced with your firm.	Prices shown by an online calculator for firms of 1 to 10 attorneys; larger firms call sales. Westlaw Advantage starts at $256.75 a month.

Products change often. Ask both vendors to show each point in a live demo, and put anything important in the contract.

Why teams choose Gotham

Built for large firms

Shared matters, roles and ethical walls. SSO, SAML and SCIM. Firm workflows, playbooks and a library of agent skills. SOC 2 Type II, ISO 27001 and data stored in your own country. Gotham Pro is priced with your firm.

An agentic citator for Indian law

India is the most complicated jurisdiction to get right. Gotham's legal ontology records each holding, bench and statute version. Its agents read every later judgment that cites a case and show, point by point and with the passage, whether it was followed, distinguished, doubted or overruled.

Indian law is built in

Gotham includes 365 million Indian legal documents from the Supreme Court, all 25 High Courts, tribunals and regulators, with citations to the paragraph. Thomson Reuters does not publish Indian coverage for CoCounsel.

Your data stays in India

Gotham stores Indian customers' data in India. Thomson Reuters does not publish data regions for CoCounsel.

Indian court work end to end

Draft in the court's format, track cases by CNR, keep a hearing diary, then stamp, sign and file, in the same workspace as your research.

What CoCounsel does well

Westlaw and Practical Law

CoCounsel reasons from Westlaw primary law with KeyCite and Key Numbers, and from Practical Law guidance written by more than 650 attorney-editors. For US and UK research, this content is hard to match.

Checks on cited authority

Deep Research Verify checks whether a cited Westlaw or Practical Law authority supports a specific statement, and Brief Builder validates authority as it drafts.

Microsoft 365

CoCounsel works inside Word, Outlook and Teams, with iManage, SharePoint and other systems.

How to test both fairly

Pick one real, bounded piece of work, not a demo question.
Give both products the same documents and the same question.
Agree beforehand what a good answer needs: the right authorities, pinpoint citations, the right format.
Have a qualified lawyer check every answer against the source.
Time the corrections, not just the first draft.
Check permissions, data deletion, exports and audit logs as well as output quality.

Include an Indian research question that needs Supreme Court and High Court authority, and a US or UK question if you have cross-border work, so you see each tool where it is strongest.

You want one platform for research, drafting, review and filing.

Stay with CoCounsel if

You already pay for Westlaw and Practical Law.

You are a small US firm that wants to buy online.
