Legal research
CoCounsel
Generative AI assistant integrated with Thomson Reuters legal research and drafting products.
Last observed 48 days ago. Records are treated as awaiting re-check after ninety days.
Only some data-handling statements were found. The checked sources did not contain all three of a confidentiality, training, and data-location statement. That is a gap in what the vendor publishes, not a finding about the product. Ask the vendor directly, or weigh it however your firm sees fit.
Editorial assessment
A research assistant for small firms that publishes a firm-size scope and a clear no-training statement.
This section is the CounselAtlas editorial desk’s own reading of the dated facts below. It is not a vendor statement, not a rating, and not a recommendation. Every product fact it rests on is recorded with a source in the record.
What it is
A legal research assistant. The vendor addresses small firms, and the checked source contains both a confidentiality statement and a no-training commitment.
What it is not
It is not a citator with the depth of the long-established research platforms, and it is not a drafting tool. It is a research surface.
Who it tends to fit
- Small firms in the 2-5 range, which the vendor's firm-size language addresses
- General-practice firms that need research help without a large-platform contract
- Firms that weight a published no-training commitment heavily
Who it tends not to fit
- Firms that need a citator with decades of editorial treatment
- Firms that need drafting or review rather than research
- Firms outside the firm-size band the vendor names
What to ask before you buy
- What is the underlying source of the answers, and how current is it?
- How do I check a citation the assistant returns before I rely on it?
- What happens to my queries, and can I see the no-training commitment in the contract?
- Does the price change as my firm grows past the band the vendor names?
Limits in the record
- The vendor's firm-size language points at the 2-5 band, so larger and solo fit is not established by the checked source.
- It is a research surface, so it does not cover drafting or review work.
How it sits in Legal research
Inside legal research, this is the small-firm option. Lexis+ AI is the large-platform option with a different contract shape. The practical difference is usually not answer quality but whether you want a focused subscription or a seat inside a platform you may already pay for.
Reading the vendor’s wording
The vendor publishes both a confidentiality statement and a no-training commitment, which is more than some research tools state. The firm-size language points at the 2-5 band.
How to evaluate it in a trial
- Ask what the underlying source of answers is and how current it is.
- Take a question you already know the answer to and check whether the citation holds up.
- Confirm the price and whether it changes as the firm grows past the 2-5 band.
- Ask to see the no-training commitment in the contract, not just the marketing page.
What adopting it costs
It is a focused subscription rather than a platform seat, so adopting it does not require leaving an existing research platform. That also means it can sit alongside one, which lowers the switching risk.
Closest alternative
Lexis+ with Protégé — The large-platform option with a different contract shape. This one is a focused subscription; that one is a seat inside a platform.
