Monitor sources. Detect developments. Preserve the record.
Follow global news and RSS sources, track the keywords and entities that matter, capture webpages and video, and seal every finding into a signed, verifiable case record.
Free to use · Chrome MV3 extension · Runs in your browser
Every source, every language, in one feed.
Watchlists scan thousands of outlets in real time, translate and score each hit, extract entities, and file the ones that matter straight into your case.
From thousands of articles to connected case context.
Case Watch scans saved sources, matches articles to your watchlists, scores relevance, extracts entities, and groups related alerts into briefings. Captures, alerts, notes, indicators, and artifacts can then be explored in the case graph.
Global news + RSS
Poll saved sources and process large article sets by case.
Keywords + topics
Match incoming articles against the terms and patterns you follow.
Relevant alerts
Review matched terms, confidence, source metadata, and article text.
People, orgs, places
Extract and review entities that connect related stories.
Context summaries
Group related alerts into readable updates with uncertainty notes.
Connected record
See captures, alerts, entities, indicators, and artifacts together.
RSS and news feeds are polled by case.
Review connected people, organizations, places, and identifiers.
Save rendered pages, scripts, headers, screenshots, and clips.
case 2
From source monitoring to signed record.
Create a case
Use a case to organize source feeds, watchlists, alerts, captures, notes, tags, and exported records around a topic or workflow.
Monitor sources
Add news and RSS sources, define watchlists, poll feeds manually or automatically, and review matched articles, entities, relevance scores, and article text.
Capture and export
Capture pages and video clips from Chrome, save useful alerts to the case, add notes and annotations, then export a signed ZIP with manifest data and artifacts.
Capture pages while you work.
Install the Manifest V3 extension, connect it to a case, and capture pages manually or passively. OSINT Ledger stores the page content, screenshots, video clips, headers, timestamps, hashes, and related notes in the same case workspace.
- Manual + passive captureTrigger a one-off capture or let passive mode save pages as you browse.
- Rendered pages + JavaScriptCapture the page after browser rendering, including JavaScript-heavy content.
- Per-case capture tokensIssue credentials for a specific case instead of relying on shared browser state.
- Page data + indicatorsReview HTML, MHTML parts, JavaScript signals, selectors, extracted indicators, and metadata.
- MHTML, screenshots, video clipsSave full-page renders, screenshots, headers, and optional WebM clips for interactive content.
Export a case record with artifacts and hashes.
Export packages the case into a ZIP with captured pages, saved alerts, notes, timestamps, manifest data, and artifact hashes. The public verify endpoint checks the manifest signature and re-hashes the exported artifacts.

}Check exported records without an account.
Share the ZIP with someone who needs to review the record. They can upload it to /api/verify — no account required — and check the manifest signature, artifact hashes, and case event chain.
- › No install. Works from any terminal or upload form.
- › Verifies both the manifest signature and every artifact hash.
- › Confirms the append-only event chain is contiguous.
