# Wikinest > A team wiki: spaces, page trees, versions, comments and permissions per space. Wikinest is a knowledge base for you or your team. Write pages in Markdown with a toolbar and live preview — panels, tables, task lists, code, status lozenges and page links — and keep them in spaces with a page tree, versions you can compare and restore, labels, templates and search. Work alone in your browser, or share a space in a Teamspaces workspace with admins, editors, commenters, readers and guests, inline comments and live updates. Wikinest (Knowledge base and team wiki) is an app of usefulweb.app (https://usefulweb.app/): a full program that runs in the browser. Its engine is deterministic and the same functions are exposed as tools, so an agent can compute exactly what the app shows. ## Use it - Landing page: https://wikinest.usefulweb.app/ - Workspace (browser app): https://wikinest.usefulweb.app/app - open a project with https://wikinest.usefulweb.app/app#project= or a template with https://wikinest.usefulweb.app/app#template= - Project file format (JSON Schema): https://wikinest.usefulweb.app/project.schema.json - Tutorials: https://wikinest.usefulweb.app/tutorials - JSON API: POST https://wikinest.usefulweb.app/api/v1/tools//calculate (catalog: https://wikinest.usefulweb.app/api/v1/tools) - OpenAPI: https://wikinest.usefulweb.app/openapi.json - MCP (Streamable HTTP): https://wikinest.usefulweb.app/mcp ## Engine tools - [Wikinest Markdown to HTML](https://wikinestmarkdowntohtml.usefulweb.app/): Turn wiki Markdown with panels, status lozenges and a table of contents into safe HTML. Part of [Wikinest](https://wikinest.usefulweb.app/) (ownerApp: wikinest). API: POST https://wikinest.usefulweb.app/api/v1/tools/wikinest-markdown-to-html/calculate · MCP tool `wikinest_markdown_to_html` - [Wikinest Page Diff](https://wikinestpagediff.usefulweb.app/): Compare two versions of a page: added, removed and changed lines plus a unified diff. Part of [Wikinest](https://wikinest.usefulweb.app/) (ownerApp: wikinest). API: POST https://wikinest.usefulweb.app/api/v1/tools/wikinest-page-diff/calculate · MCP tool `wikinest_page_diff` - [Wikinest Confluence Import](https://wikinestconfluenceimport.usefulweb.app/): Convert a Confluence HTML export into Wikinest pages in Markdown with the page tree. Part of [Wikinest](https://wikinest.usefulweb.app/) (ownerApp: wikinest). API: POST https://wikinest.usefulweb.app/api/v1/tools/wikinest-confluence-import/calculate · MCP tool `wikinest_confluence_import` ## Formats - Import: Wikinest project (.wikinest.json), Markdown files (.md) or a folder as ZIP, Confluence HTML export (.zip or .html), Read-only page link (#share=) - Export: Wikinest project (.wikinest.json), Page or space as Markdown (.md / .zip), Page or space as HTML (one file, images included), Page or space as PDF, Read-only page link ## Limits - Pages are edited as a whole: two people typing in the same page at the same time are merged when publishing, not character by character. - Guests and viewers cannot create pages in shared spaces (Teamspaces lets only members, admins and owners create documents); permissions apply to a whole space, not to single pages. - Page statistics (views) are counted only in your own browser; there is no central analytics. - Markdown exports leave images out; HTML exports embed them. PDF exports show images as their description. - Confluence imports skip page history, comments, Jira macros, page properties reports and other macros without a Wikinest equivalent (their text is kept). - Very long share links (big pages) may not fit in every chat app; send an HTML export instead.
