Problem
Care-experienced people are legally entitled to their own social care records, but these documents are written in professional jargon, often dense or patchy depending on the author, and lack context. Navigating these records to piece together one's own story, understand decisions, or identify legal entitlements is time-consuming and emotionally taxing, leaving individuals feeling reduced to a case file rather than a whole person.
Solution
Limn is a free, not-for-profit AI desktop app that helps care-experienced people make sense of their own care records. Users drag in PDF, Word, or text files, which are processed entirely on-device to summarize key events, people, and dates. The app allows users to ask questions in their own words, receiving plain-language answers with citations showing where each response came from, and includes a knowledge base covering UK legislation like the Children Act 1989 and leaving care entitlements. Limn also surfaces positive details that may be easily missed in the records, and is built on privacy by architecture—it is structurally impossible for documents or conversations to leave the device, with no cloud, no API calls, and no tracking by design.
Target Audience
Primary users are care-experienced individuals in the UK—particularly young people leaving care—who want to understand their own social care records, alongside advocates and researchers supporting them in navigating these documents.
