Free evidence board · No sign-up
See how everything connects.
AnacapaChart is a free online evidence board. Pin photos, notes, videos and links, join them with string, and select anything to light up its direct connections.
Free. No sign-up. Works on desktop, tablet and phone.
Try it: hover or tap any card. Only its direct links light up.
Pin everything you find
Photos, notes and documents each land on the board as a card you can move, rotate and resize.
Bring in video, posts, maps and files
Paste a YouTube link, a social post, an article or coordinates, or attach a PDF. Each becomes a live card with its source and date.
Connect what belongs together
Draw a string between two cards, label it, and mark it suspected when you are not sure.
See direct links light up
Point at any card and only its direct connections glow. The noise fades away and the story stands out.
Find how two things connect
Pick any two cards and AnacapaChart traces the shortest chain of links between them.
Mark what you can prove
Give every card a category, status, source and date. Files get a SHA-256 fingerprint so you can show they have not changed.
Put events in order
Arrange the board by date or open the timeline panel to read your case as a story.
Studio mode and seven lights
Switch to a realistic cork board and choose the light. Now showing: Warm.
Publish it anywhere
Create a snapshot link or paste the embed code into your blog. Readers can explore the board but cannot change it.

Read the guidesQuestions
Is AnacapaChart free?
Yes. The board is free to use and needs no account. We show ads on our guides and home page, never inside the board.
Do I need an account?
No. Open the board and start pinning.
Where are my boards stored?
Boards autosave in your browser on this device and stay there until you clear your site data, so export a board file when a board matters. A share link uploads a copy of the board to our storage, so do not share anything sensitive that way.
Can I add video, posts and maps?
Yes. Paste a YouTube or Vimeo link, a social post, an article or map coordinates, or attach video, audio and PDF files from your device.
Which browsers work?
Current versions of Chrome, Edge, Firefox and Safari on desktop, tablet and phone.
