Every fact sourced
Each fact, date and quote points to the exact passage it came from.
Solutions / Themis
Every fact points to its source.
Themis is a case workspace for lawyers and investigators. It turns statements, messages and hours of footage into one sourced record of the case. The AI proposes, and a person decides.

Interface concept with a fictional case. Themis is in validation.
The problem
Evidence piles up faster than people can review it.
Cases are still built by hand, in spreadsheets and word documents, and the AI tools that promise to help can't be trusted to quote accurately.
90%
of practitioners build case chronologies in Excel or Word, where source links get lost.
17–33%
of answers from leading legal AI tools were hallucinated in an independent test.

The product
One sourced record. Every view generated from it.
The timeline, the contradictions, the court bundle: each is a view over the same record, so a correction made once shows up everywhere.
Living timeline
A chronology built from documents, messages and footage, with camera clocks corrected.
Contradictions and gaps
Flags where accounts disagree and where proof is missing.
Visual evidence
Upload images and video, label people and objects, and follow them across cameras.
Ask the case
Plain-language search in Sinhala, Tamil or English pulls up the right moments and passages.
Court-ready output
Bundles, schedules and reports in the court's format, with the method attached.
Built to be trusted
The AI proposes. A mechanism checks. A person decides.
- 01 · AIProposes
Suggests facts, dates and links, always with the passage it read.
- 02 · MechanismChecks
Rejects any quote that doesn't match the source word for word.
- 03 · PersonDecides
Only what a lawyer or investigator accepts enters the record.
Verified, not trusted
Every quote must match the source exactly before it's shown. Nothing enters the record until a person accepts it.
Client data stays local
An encrypted vault on the user's own machine that works offline. A file leaves only when the user chooses an AI action that needs it.
Face matching gives leads, not answers
Off by default, limited to the user's own case, and needing a second reviewer and corroboration before anything is exported.
Never offered
Open-web face search, image scraping or live-feed identification. Wrongful arrests show why.
