Evidence infrastructure — pre-launchFollow the
evidence.
SourceLayer connects public claims to original sources, transcripts, documents, and records — so anyone can verify context, trace narratives, and understand what is actually supported by evidence.
"Official X said Y at the Sept. 14 hearing."
"…the figure of 3.2% reflects the prior quarter, not the projection…"
The internet broke context.
Public information moves through fragments — not sources. By the time a claim reaches you, the evidence behind it is often invisible.
- Claims travel faster than verification.
- Clips are removed from their original meaning.
- Sources are buried or inaccessible.
- AI-generated summaries amplify uncertainty.
- Most people cannot trace a claim back to its origin.
A new layer of the internet: context you can trace.
SourceLayer connects every claim to its origin and reconstructs full context with transparent sourcing.
Source linking
Every claim tied to original material — documents, transcripts, datasets, and records.
Context expansion
Surrounding information automatically surfaced so quotes are never read in isolation.
Timeline reconstruction
Events ordered across time so narratives can be checked against the record.
Confidence indicators
Transparent signals of evidentiary strength — high, medium, or low.
Source chains
Full provenance — from primary record to the place a claim was first repeated.
From fragment to evidence in three steps.
Input a claim
Paste a quote, headline, clip, or statement. Ask: did this official actually say X?
Source retrieval
SourceLayer pulls the underlying material — transcripts, video, official records, datasets.
Context reconstruction
Full quote, timestamp, surrounding statements, related entities, and a confidence score.
We don't interpret truth.
We trace it.
SourceLayer does not decide what is true. It shows:
- where information came from
- how it connects to other records
- what supports or contradicts it
- how strong the underlying evidence is
Built for the people who need the record.
Journalism & investigations
Move from a claim to the underlying record without rebuilding the trail by hand.
Academic research
Cite primary material with full provenance and timeline reconstruction.
Legal discovery support
Surface relevant transcripts, filings, and records connected to a statement.
Public accountability
Track what was said, when, by whom, and what the record actually shows.
Policy research
Connect public statements to legislation, hearings, and official datasets.
Media verification
Check viral clips against original transcripts and source recordings.
An evidence infrastructure layer for the internet.
A new category at the intersection of public records, AI retrieval, and verifiable information.
Structured data moat
A growing graph of public records, transcripts, and official documents — structured for retrieval, not just search.
AI-native retrieval
Context reconstruction built on modern retrieval and reasoning — designed for evidence, not summarization.
Citation network effects
Every traced claim strengthens the underlying citation graph and improves the next retrieval.
Expandable surface
Starts with FOIA and media records; extends to global public-records ecosystems and partner archives.
A glimpse of the interface.
A simulated view of what verification feels like when the source is one click away.
