Whisp

London-based AI fact-checking and validation platform that claims to help law firms verify AI-generated legal documents against trusted sources. Founded 2023 by Luca Frost (now in Abu Dhabi), registered as Whisp Limited in Covent Garden. 2-10 employees, unfunded. Listed in F6S’s top 32 London LegalTech companies. Claims integration with DMS, eDiscovery platforms, and Microsoft Office, and cross-references against case law and legal commentary — but NONE of these claims are independently verified. The whisp.ai website positions the tool as general fact-checking for ‘people and organisations,’ creating ambiguity about whether legal is the primary or secondary focus. Trustpilot shows 2.6/5 from 4 reviews with a warning that the company has been displaying Trustpilot content incorrectly. No law firm deployments found. No product documentation, demos, or feature walkthroughs found publicly. No privacy policy or security documentation found — disqualifying for firms with data governance requirements. No coverage in any UK or US legal tech publication. Patent WO2019043379A1 for fact-checking methodology. Competitive survival risk is high — Harvey, CoCounsel, and new entrants like RealityCheck (ATL March 2026) are building verification features natively. The AI hallucination problem is real and urgent (Reuters Feb 2026: lawyer sanctioned, Stanford: 1/6+ hallucination rate), but whether Whisp actually solves it is entirely unverified.
