FAQ
Is AnnexVTT a replacement for Roll20, Foundry, or Owlbear Rodeo?
For investigation games, Annex is built to be the home base for your table — the case, the archive, the sheets, the dice, and the fight, all in one place. For Call of Cthulhu, Delta Green, or Vaesen, it is built to run the whole night, case to combat. Step in and what your investigation needs is already here.
What games is it for?
Systems where investigation is the game: Call of Cthulhu, Delta Green, Vaesen, World of Darkness, and similar mystery or horror campaigns. If a session is mostly spent piecing together what happened and what to do next, Annex is built for that table.
Does it do combat, dice, and character sheets?
Yes. Annex has a Conflict surface — a square or hex grid with tokens, two-way HP tracking, an initiative order, and dice — so a fight runs without leaving the table, alongside lightweight character sheets. It scales to what the game needs, from a quick lethal skirmish to a gridded standoff. More is on the way: if there is something your table needs that you do not see, send it through the contact form — I am always taking ideas.
Is it free?
Yes. AnnexVTT runs entirely in the browser and is free to use. There are no ads and nothing to install.
Do my players need accounts?
Boards are real-time and collaborative — players join with shared cursors and presence and work the case together live. Each collaborator signs in so their edits and contributions are attributed to them.
Is my data private? Can I export or delete it?
Yes. No advertising, no per-user tracking, and no third-party trackers. Your boards are yours: you can export everything as a ZIP and delete your account at any time from Settings. The Privacy page details exactly what is stored and why.
Is the artwork AI-generated?
Some of it is. The landing illustrations and the AnnexVTT logomark are AI-generated; everything that ships — art, code, words — is reviewed and approved by a human first. AI is a contributor here, not the one making the call.
How finished is it?
Annex is built and run by one person, in the open, and growing on a steady cadence — features added, bugs fixed, rough edges sanded down. It is a working tool today, with more landing regularly.
