An AI Dungeon Master with a perfect memory

No setup Bring your own AI — or use our managed option

An AI Dungeon Master that actually remembers your story.

Your AI forgets after a few sessions. Wistmere doesn't — real rules, fair dice, and a world that stays consistent for months.

Join the waitlist See how it works

D&D 5e & Pathfinder · fair dice · play solo or between sessions

Three sessions in, the cracks show — your AI forgets your rival's name, your bag of holding, the fact that you're level 6, and the story you built quietly falls apart.

It doesn't have to. Wistmere keeps every thread — so the tale only deepens.

How it works

Your AI GM forgets. Wistmere remembers.

Your AI runs the table. Wistmere quietly keeps track of everything that happens — so nothing slips through the cracks.

Your AI plays

Bring your own Claude, ChatGPT or Gemini to run the campaign — narrating scenes, voicing NPCs, and adjudicating the action turn by turn.

The mind at the table

Wistmere remembers

The AI tells Wistmere what happened; Wistmere writes it all down — every event, item, level-up and relationship — and keeps it safe for good.

Every event, kept

Recall it forever

Sessions later, Wistmere reminds the AI exactly what it needs to know — so your world stays consistent, even after the AI itself has forgotten.

No drift. Ever.
See it in action

Your story on the left. Your world, remembered, on the right.

A peek at the table: the AI narrates, you act, and Wistmere quietly records what matters.

What you get

Built for the long campaign

Everything a table needs to keep a story consistent across months of play.

A world that stays consistent for months

Characters, inventory, NPCs and lore are remembered exactly — the saga only grows richer, never contradicts itself.

Dice your GM can't fudge

Every roll is cryptographically verifiable — no quiet re-rolls, no phantom crits. Trust the result, every time.

Real rules, actually enforced

5e & Pathfinder by the book — spell slots, conditions and saves are tracked, not hand-waved away.

Use the AI you already pay for

Connect Claude, ChatGPT or Gemini — or let us manage it for you. Your AI, your choice.

Level up by the book — correct every time

Step through advancement properly: new spells, features and HP applied right and remembered for good.

See your scenes — art conjured mid-session

Bring key moments and characters to life with art generated on the fly, without breaking the flow of play.
