Open Source Intelligence Platform
Collect at scale.
Understand what matters.
Aletheia brings the open web and social media into a unified view, uncovering meaning, mood, and motive across 30+ languages.
Investigations should be won by the quality of your questions, not by how many tabs you can keep open.
Built for governments, investigators, and newsrooms.
One investigation, end to end.
See how the same case moves from raw sources to citable facts. The views below are interactive recreations of the real platform.
Demo scenario: coordinated influence activity around a parliamentary election in Arvenia, a fictional country. All data below is illustrative.
Step 1
Point it at sources.
Paste a channel, a site, or a handle. Aletheia backfills the archive and keeps collecting in real time: text, video, audio, and images, all indexed by content, not just by title. You can also bring your own documents, archives, and recordings.

Step 2
Ask in plain language.
Describe what you are looking for. Semantic search finds content by meaning, not exact words, so a query in English surfaces a Telegram video in Russian or a Romanian news article, with no keyword overlap required. Or search by image to match a photo across video and stills.

Protest footage tagged only “вечер в столице”, matched by transcribed audio and scene content.

Local coverage of the energy-price rally, including organiser names and permit details.
- VIDEO SEGMENTYouTube · Arvenianmatch 0.84
A 40-second segment inside a two-hour broadcast, located by its transcript, not its title.
Step 3
Read the map, not the feed.
Aletheia groups thousands of posts into the stories they are actually telling. Each bubble is a narrative detected automatically across your sources. Its size is how loud it is, and the timeline shows when it surges.
Try it: click a narrative to see its keywords, the people and places inside it, its emotional tone, and how it built over time.
Step 4
See who claims what, and how.
Pick any claim and Aletheia shows who supports it and who opposes it across your sources, with the exact quote, whether it is the author speaking or someone being quoted, and the rhetorical techniques in play, flagged automatically.
Try it: switch between the tracked claims and expand a mention to see the evidence behind the judgement.
Ballots from the diaspora arrived pre-marked — anyone can see the numbers do not add up. This was decided before a single vote was cast.
Step 5
Turn talk into facts you can cite.
From the same sources, Aletheia extracts concrete events: who did what, to whom, where, and when. Each one is typed, confidence-scored, and linked to the sentence it came from.
Try it: filter by event type, then open “Show evidence” on any event.
Open API & custom analysis
Query your ingested content programmatically, run it through Aletheia's analysis models, or pipe it into your own and third-party tools.
Who it's for.
The same platform, three very different days at work.
Journalists & newsrooms
Chase the story, not the collection. Backfill a source in minutes, search it by meaning, and pull quotes with the link, date, and original language intact, ready for publication.
OSINT & research teams
Scale coverage without scaling headcount. Monitor hundreds of sources in 30+ languages, with clustering, stance, and event extraction running on top, plus an API to feed your own pipeline.
Governments & institutions
See influence activity early. Narrative surges, coordinated framing, and structured events, with every judgement traceable to its source. Deployment and data-handling options on request.
