🧭 Investigation Toolkit: What This Group Is For Resource
Links to sites run by other organizations. Each link opens in a new tab and is checked once a month.
The cards below collect tools that reporters, advocates and researchers use to check whether a photo or video is what it claims to be, trace where an image came from, save web pages before they change or disappear, collect and study social media material, organize a long investigation, and stay safe while doing it. They follow the order of a typical verification job: Verify (reverse image search, face tools, metadata and forensics, deepfake checks), Preserve (web archiving), Collect (social media research), Organize (data organization and analysis) and Protect (advanced online safety). Most entries come from the Bellingcat Online Investigations Toolkit, a community-maintained list; every link here goes to the tool's own site, and each link is checked once a month. Treat results as leads to confirm with a second source, not as proof. Face search and people search raise real privacy and legal questions, so read the Privacy and Security section first and follow the law and each site's rules.
🖼️ Reverse Image Search Tools Resource
Links to sites run by other organizations. Each link opens in a new tab and is checked once a month.
Reverse image search finds where else a picture appears online and which copy is oldest. Reporters use it to test a viral photo, find the original photographer, spot a photo recycled from an older event, and locate a place or object. Run the same image through more than one engine, because each one indexes different parts of the web.
5 links: show the list
- Google Lens ↗ FreeGoogle's image recognition tool. Upload or paste a photo to find matching pages, identify objects, text and landmarks, and narrow down where a photo was taken.
- InVID-WeVerify Verification Plugin ↗ FreeA free browser plugin built for fact checkers. Runs one image through several reverse search engines, pulls keyframes from a video, reads metadata and applies forensic filters.
- RootAbout ↗ FreeReverse image search that compares your photo against images saved in the Internet Archive, which can surface older versions of a picture.
- Search by Image ↗ FreeA browser extension for Chrome, Firefox, Edge, Safari and Opera. Right-click any image and send it to many reverse search engines at once. The page links to each browser's install page.
- TinEye ↗ FreeA reverse image search engine that can sort matches by oldest first, which helps trace an image back to where it first appeared.
🙂 Facial Recognition Tools Resource
Links to sites run by other organizations. Each link opens in a new tab and is checked once a month.
Tools that compare faces or search for look-alike faces. They can give a lead on who appears in a photo or whether two photos show the same person, but they make mistakes and a match is never an identification by itself. Using them on private people raises privacy, accuracy and legal concerns, and some of these sites are controversial. Confirm any lead with reporting before you publish a name.
6 links: show the list

🔬 Metadata and Image Forensics Resource
Links to sites run by other organizations. Each link opens in a new tab and is checked once a month.
Metadata is the hidden information inside a photo or video: camera model, date, software and sometimes GPS location. Forensic tools look for signs of editing, such as cloned areas or compression that does not match. Use them to check a file you received and, with the removal tools, to strip identifying data from files you publish. Metadata can be missing or faked, so it supports other evidence rather than replacing it.

🧩 More Image and Media Tools Resource
Links to sites run by other organizations. Each link opens in a new tab and is checked once a month.
Helpers that do not fit the other image groups: spotting AI-generated faces and fake audio, removing objects, joining photos into panoramas, finding duplicate files and arranging reference images. Detection tools are guesses with error rates, so use them to raise or lower suspicion, not to settle a question.

🗃️ Web Archiving Tools Resource
Links to sites run by other organizations. Each link opens in a new tab and is checked once a month.
Pages get edited, deleted and taken down, sometimes right after a story runs. Archiving tools save a copy with a date so you can show what a page said, watch a page for changes, and keep social media posts that may vanish.

🔎 Social Media Research (Multiple Platforms) Resource
Links to sites run by other organizations. Each link opens in a new tab and is checked once a month.
Tools that work across many platforms at once: finding the same username in many places, checking whether an email address shows up in breaches, and collecting posts for analysis. A username match is only a lead, since different people share names; confirm identity with other details before you connect an account to a person. Respect platform rules and privacy law, and keep notes of what you searched and when.
