Free Online Evidence Board Maker
AnacapaChart is a free evidence board that runs in your browser. Put people, notes, photos, videos, documents and web links on one board, join related items with string, and see how everything fits together. There is nothing to install and no account to create.
What you can add
- People and organisations. Give any card a category such as person or organisation, a status from verified to disputed, a source and tags.
- Notes and text. Write short notes, labels and open questions. Colour the notes so different kinds of evidence are easy to tell apart.
- Photos and files. Add photos, video, audio and PDFs from your device. Each file gets a SHA-256 fingerprint so you can show later that it has not changed.
- Links, videos and posts. Paste a YouTube or Vimeo link, a map location, an article or a social post and it appears as a card on the board.
- Connections. Join cards with labelled strings. Mark a link as suspected and it is drawn dashed.
- Dates. Give a card an event date and see everything in order in the timeline panel.
How to get started
- Open the board and pick Note, File or Link from the toolbar.
- Add your first items: type a note, drop in a photo or paste a link.
- Fill in the evidence details: category, status, source and date.
- Use the string tool to connect related items and add a label that says how they relate.
- Select any card to make its direct connections glow. Select two cards to trace the shortest path between them.
- Export a PNG, save a board file or open the printable case report.
A fictional example: the missing ledger
Pin a photo of the ledger, the clerk's statement, a link to a CCTV clip and the shipping manifest. Connect the clerk to the statement and the clip to the loading dock. Select the dock card and the clip and the manifest light up, showing at a glance what touches that location. The board organises what you know. It does not prove anything by itself.
Saving, sharing and export
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.
You can export a PNG image, save a board file you can import again later, or open a printable case report and save it as a PDF from your browser.
