Alexandrie turns your own words into a map of what you're thinking about, alone or together. Write knowledge cards the way you'd write notes, or pull from real, curated sources (arXiv, OpenAlex, Crossref, Wikipedia, MIT OpenCourseWare, Guardian/BBC/Reuters, and more), and Alexandrie finds the lexical connections between them automatically, while you decide what those words are. It's built for real collaboration: invite people onto a map with precisely assigned permissions, and work on the exact same knowledge card at the exact same time as someone else. Card editing merges through a CRDT, so simultaneous edits combine cleanly instead of overwriting each other. Add a shared blackboard for sketching, shapes, and LaTeX, explore live in Search with zero setup, then save what you find into Studio.
Generate a Map builds a map automatically, either from up to 20 topics you choose or from an uploaded document (currently in beta). Alexandrie picks sources, extracts knowledge cards, and lays out the connections between them for you.
Create map starts from a blank canvas, if you'd rather build a map card by card yourself.
Alexandrie Search skips maps entirely: type a topic and explore results live. Nothing is saved unless you choose to send it into Studio.
Click a card to select it, double-click to zoom in, drag the canvas to pan, and scroll to zoom. Hovering a relation line shows which words connect two cards. The pencil icon on a card opens its editor, and the toolbar's Add Knowledge button creates a new one.
The sliders and 3D projection cube let you tune how cards connect and lay out spatially, reshaping a generated map's structure instead of only accepting the first layout.
Manage Map (available to admins and the map's creator) controls sharing, visibility (public or private), invitations, and the embed code for a public map.
Invite people onto a map by email and assign each one a permission level: read, write, or admin. Collaborators can work on the same map, including the exact same knowledge card, at the same time; card editing is built on a CRDT, so simultaneous edits from different people merge cleanly instead of overwriting each other.
Every map also has its own Blackboard (a shared canvas for freehand drawing, shapes, text, and LaTeX) and Map Chat, so collaborators can sketch and talk through ideas without leaving Studio.
Starred is a personal collection of knowledges saved from anywhere on the platform, including from Search results, kept separately from any one map so you can organize them or send them to a map later.
Quick note is a one-click way to capture a thought straight into Starred from the homepage, with zero setup.
The homepage also shows a feed of knowledge cards from maps you have at least read access to, and a small set of recommended maps to explore.
Browse public and authorized maps on the Discover page, and duplicate any of them into your own account to build from. Every user also has a public profile listing their public maps, total stars received, and join date.
See the Plans page for the full feature breakdown.
Alexandrie turns your own words into a map of what you're thinking about, alone or together. Write knowledge cards the way you'd write notes, or pull from curated sources like arXiv, Wikipedia, and MIT OpenCourseWare, and Alexandrie automatically finds the lexical connections between them, while you decide what those words are. It's built for real collaboration, from precisely assigned permissions to same-card real-time editing, plus a shared blackboard, live search, and a home for every map you save.
Alexandrie analyzes the words you actually use in each knowledge card (lemmatized, so “connect,” “connects,” and “connection” count as the same concept) and draws a relation wherever two cards share meaningful vocabulary. It's deterministic lexical overlap, not a language model guessing at what might be related, so every connection you see is traceable back to your own words. With 100 knowledge cards there are up to 4,950 possible pairwise relations, far more than anyone would find by comparing cards manually.
No. Alexandrie runs entirely in your browser; no plugin, desktop app, or extension required.
Two ways: “Generate a Map” builds one automatically from up to 20 topics or from an uploaded document, picking sources and laying out connections for you. “Create map” starts from a blank canvas if you'd rather build it card by card.
Search is live and disposable: type a topic, get results as an on-the-fly map, and explore before creating anything permanent. Studio is where your saved maps live; everything you build or generate ends up there, and a Search session can be saved into Studio whenever you're ready.
Yes, currently in beta. Upload a document and Alexandrie extracts knowledge cards from it; image and attachment retention limits depend on your plan.
When generating or searching, Alexandrie draws on a curated set of sources: Wikipedia, arXiv, Guardian/BBC/Reuters, MIT OpenCourseWare (math, economics, finance), Wikiversity and Wikibooks, the Math/MathOverflow/Money/Quant StackExchange network, OpenAlex and Crossref (citation-grade academic metadata across disciplines), PhysicsForums worked exercises, the Stanford Encyclopedia of Philosophy, and general web search, not just a single generic scrape.
Click the pencil icon on any card to open its editor, with full formatting, tables, undo, and image/PDF attachments where your plan allows.
The sliders and 3D projection cube reorganize how cards connect and lay out spatially, letting you reshape a generated map's structure instead of only accepting the first layout.
Yes, any card can be exported as PDF, an HTML page, plain text, or Markdown, directly from its editor.
Alexandrie ships 50+ visual themes, each individually checked for WCAG color contrast so text stays readable no matter which one you pick. The free Essence tier includes 12 of them; paid tiers unlock all 50+.
Yes. Invite collaborators by email, assign each one a precise permission level, and work together on the same map, including the exact same knowledge card, at the same time.
Read (view only), write (can edit), and admin (can also manage sharing and settings); the map's creator always keeps full ownership.
Yes. Card text editing is built on a CRDT (conflict-free replicated data type), so two people's simultaneous keystrokes merge cleanly instead of one overwriting the other.
A shared drawing surface on every map: freehand drawing, shapes, text, and LaTeX, visible and editable by every collaborator, and persisted so it's still there next time anyone opens the map.
A chat scoped to each individual map, for collaborators to talk through what they're building without leaving Studio.
Yes. Toggle a map's visibility to public and it becomes shareable, including an embed code for placing it on another page.
Your personal collection of knowledges saved from anywhere on the platform, including from Search results, kept separately from any one map so you can organize or send them to a map later.
A one-click way to capture a thought straight into Starred from the homepage, with zero setup, so you can organize it into a map later instead of deciding where it belongs right away.
Yes, through Discover: browse public and authorized maps, and duplicate any of them into your own account to build from.
Yes. Your profile page lists your public maps, your total stars received, and your join date, shareable like a portfolio.
Yes, a feed of knowledge cards from maps you have at least read access to, each one linking straight to that knowledge on its map.
Yes, the homepage surfaces a small set of maps to invite exploration beyond your own.
Yes, a built-in inbox lets you message other users directly, tied into the same notification system as everything else.
Yes. The Essence tier is free, with generous limits on maps, searches, and themes; see the Plans page for the full breakdown.
Essence is free. Atelier is 10 CHF/month. Maison is 50 CHF/month (coming soon). Sur-mesure is a custom enterprise tier; contact us to discuss.
Not yet. API access is planned for the Maison tier once its pricing is finalized.
Yes. The platform is served entirely over enforced HTTPS/TLS, uses CSRF protection and a strict Content Security Policy on every page, scopes session cookies to same-site requests, and the codebase goes through regular internal security review.
