Investigation Notes is a private, browser-based case manager for OSINT work. Organize subjects, usernames, contact details, sources, and timelines per investigation, switch between multiple cases, and export your work as JSON, HTML, or PDF. Everything is stored locally in your browser — nothing is uploaded.

This is a private, browser-based workspace for keeping OSINT investigation notes organized — track findings, record sources, and build a timeline as you work. Everything stays on your device; nothing is uploaded, and there is no account to create.
Use it alongside the investigation tools to capture what you find as you go. When you need techniques rather than a notepad, the OSINT guides cover the methods, and the tools directory lists what to use for each task.
Good OSINT notes record not just what you found but where and when you found it — a link, a timestamp, and a screenshot or archived copy, since sources vanish. Separate confirmed facts from inferences, and note the confidence behind each finding so a reviewer (or future you) can retrace the reasoning. Because this workspace stays entirely on your device, it suits sensitive work where uploading case data to a third-party service would be inappropriate. Pair it with the archive tools to preserve evidence before it disappears.
All investigations are saved in your browser's local storage on your own device. Nothing is sent to a server, so export regularly to back up.
Yes. You can export and re-import investigations as JSON and generate HTML or PDF reports for sharing or archiving.
No. The tool is fully client-side; your case notes never leave your device.
