Solo playtesting at 2am, every edge case you can think of.
Run as many sessions as you want — no scheduling, no no-shows,
no waiting on Discord for a quorum. The AI plays your rules immediately,
exactly as written.
🔁
Refine + re-run loop
Edit your rules between runs, re-run instantly, see what changed.
Each iteration is tracked — compare reports side by side, spot what
broke when you tweaked the damage formula, and iterate without
losing your history.

Common questions
Answers before you start.
Does it work with my custom system?
Yes. SagaForge parses whatever rules text you paste — it's not limited
to D&D or any preset system. OSR, PbtA, FitD, diceless, card-based,
totally homebrew: if you can describe the mechanics in text, the AI
can play them.
Can it run a full campaign?
Yes — Campaign mode runs a full 3-act, 52-action
autonomous campaign and produces a chronicle. It's a Pro feature ($19/mo),
but the standard 10-action playtest report is completely free.
How is it different from AI Dungeon?
AI Dungeon is a creative writing tool; it doesn't enforce your rules.
SagaForge is a rules engine — it parses your mechanics, runs
dice rolls, tracks character state (HP, conditions, inventory), and
produces a structured report designed for the designer, not the player.
What does it cost?
The 10-action playtest is free, no account needed.
The refine-and-re-run loop and campaign mode are available on the
Pro plan at $19/mo. You can try everything
before you pay.
Can I embed it on my itch.io page?
Yes. Every report generates an embeddable card you can drop directly
into your itch.io page — just copy the embed code from the report page.
It renders inline so potential backers see a live playtest without
leaving your game's listing.
