CommonBench is a research instrument built for the people who can't afford one — and the practitioners who need answers faster than billing permits.
The common law is a public inheritance. The ability to read it, cite it, and reason with it should not be gate-kept by a £400-an-hour billing structure.
We built CommonBench because the existing options are broken: generic AI hallucinates citations, and qualified counsel is unaffordable for the people most likely to be sued.
Our bet is simple. With a curated corpus, a live verification pipeline, and a disciplined prompt architecture, we can deliver professional-grade analysis in seconds — and never invent a case.
This is not a substitute for a qualified practitioner. It is a research instrument. The output is information, cited to its source, designed to be checked. We are proud of that distinction and committed to it.
Every citation is verified against a public legal database before it reaches your screen. Unverifiable citations are stripped. We would rather return less than return fiction.
Every analytical claim carries a citation. Every citation links to the source. If you can't check our work, we aren't doing ours.
"Can I recover?" is the question every client actually asks. Every response with financial figures includes a costs estimate and net-recovery calculation.
Statutory demands. Limitation periods. Asset dissipation risk. If there's a clock running, we tell you before the analysis begins.
Six stages. A fabricated citation never survives past stage four.
After watching court hearings clog up with citations no judge had time to verify, the founder set out to build a research engine that refuses to invent. Every authority cited has to exist, has to be retrievable, and has to come with its source.
Hand-curated across England & Wales and the US. Every case tagged, summarised, and cross-checked. The verification pipeline ships with it.
Hong Kong, Singapore, and Australia added. The corpus crosses 2,000 authorities. First paying users onboarded under the Starter tier.
Hard isolation between seats. SAML SSO. Direct onboarding. The first firm deployments begin.
Document drafting service launches end-to-end. EU jurisdictions under evaluation. Additional verification partners in onboarding.
We answer email like lawyers don't.
