WHO IT’S FOR

Deep forensic research for professionals working with complex evidence.

Evidence is built for professionals dealing with large, complex documentary records, especially where time, budget or team size makes traditional enterprise research tools difficult to justify.

Professional-grade forensic research without enterprise-scale licensing.

Lawyers & legal teams

For litigation, disclosure-heavy matters, case preparation and evidence review across complex document sets.

Planning professionals

For local plans, appeals, development proposals and technical evidence where the answer sits across many documents.

Planning consultants & barristers

For inquiries, examinations and complex planning records requiring disciplined source-grounded research.

Investigators & regulatory teams

For large records, competing accounts, timelines, contradictions and missing evidence.

Construction & infrastructure professionals

For technical reports, claims, programmes, correspondence and supporting evidential records.

Insurance & claims teams

For complex claims files, evidence comparison, chronology and inconsistencies across large records.

HR & employment professionals

For investigations, grievances, disciplinary matters and document-heavy workplace disputes.

Public bodies, charities & community organisations

For complex evidence where professional-grade research capability is needed without enterprise software overhead.

If your work depends on understanding what a large body of evidence actually shows, Evidence is built for you.
