CoCounsel vs Paxton: the research-AI decision for small firms

Our verdict: this is ecosystem versus rate card. CoCounsel brings Thomson Reuters' breadth — research, deposition prep, document review — with Westlaw gravity behind it, priced by quote (reported roughly $225–$500/user/mo depending on bundle). Paxton sells one self-serve seat at a published $499/mo ($2,999/yr) covering research, drafting, and document analysis across all 50 states, with a free trial and stated no-caps terms. A Westlaw firm should price CoCounsel as an add-on and negotiate; a firm starting from zero should trial Paxton first and make any quote beat a number it can already see.

Where each one wins

Pick CoCounsel if your firm already pays for Westlaw (negotiate the marginal add-on cost), litigation document review is a real workload, or the deposition-prep and review skills would replace multiple point tools at once.

Pick Paxton if you are buying research AI from scratch, want the price and terms before the conversation, practice across state lines, or simply refuse quote-only procurement on principle. The free trial is the cheapest diligence in this category.

The test that settles it

Take three real research questions your firm answered recently (sanitized). Run them through Paxton's trial and — if you can get one — a CoCounsel pilot. Open every cited authority and check it says what the summary claims; count the misses. Then compare all-in annual cost: Paxton's public $2,999 against the itemized quote. Verification quality on your matters, at a price you can hold in writing, decides it. Related: how to run AI legal research without getting sanctioned.
