Dowser Labs
Tools for the business of truth.
A free press is how truth reaches the public — but adversaries work to pollute and distort the record, and the reporters who hold the line bear real personal and professional risk. Dowser Labs builds the tools that help them carry the work through.
What we build
SourceNote
Encrypted messaging apps secure conversations — but still expose metadata, traffic patterns, and call signals that can reveal critical intelligence. SourceNote makes that exposure visible: detect risks, analyze encrypted activity, and verify communications without breaking encryption.

Journalists, newsrooms, NGOs, legal investigators, and others whose work depends on protecting sources and verifying what those sources share.
How we operate
- Processing is on-device by default. No telemetry, no cloud-stored data. Any optional third-party data enrichment is opt-in and can be disabled.
- Message content is never captured, decrypted, or stored. Our tools operate on packet headers and protocol-layer signals — the same surface a network observer already sees.
