# Reference Board Planner > Turn a list of website references into an editable board. Create an organized Pageboard from one reference per line, with optional source, type, platform and tags. Download the project and continue arranging it in Pageboard. Part of usefulweb.app (https://usefulweb.app/). Results are deterministic calculations from the inputs and the listed assumptions; the API returns exactly what the web page shows. ## Use it - Human interface: https://pageboardreferenceplanner.usefulweb.app/ (interactive tool at https://pageboardreferenceplanner.usefulweb.app/tool) - JSON API: POST https://pageboardreferenceplanner.usefulweb.app/api/v1/calculate with a JSON object of inputs (schema: https://pageboardreferenceplanner.usefulweb.app/api/v1/tool) - OpenAPI: https://pageboardreferenceplanner.usefulweb.app/openapi.json - MCP (Streamable HTTP): https://pageboardreferenceplanner.usefulweb.app/mcp - tool `pageboard_reference_planner` ## Inputs - name (text): Board name - references (textarea): References, one per line - Title | URL | Type | Platform | comma-separated tags. Only the title is required. ## Method - Each nonempty line is split into up to five pipe-separated fields: title, source URL, site type, platform and comma-separated tags. Empty optional fields may be left blank. - The board allows at most 100 references and eight tags per reference. URLs must be HTTP or HTTPS without credentials; each entry receives a stable sequential ID and an editable neutral accent. - Links are stored as text and never fetched. Screenshots must be added separately in Pageboard; use images you have permission to include. - The download is the native editable project. If its encoded data exceeds one million characters, import the project file instead of using the editor link. ## Limits - This tool does not capture screenshots, fetch URLs or import third-party galleries. Use your own links and images.
