AI Realm is a browser-based AI game master for text roleplaying games: you create a character, open a campaign and type what that character does, while the AI Game Master narrates the story and runs combat in D&D 5e inspired adventures.
The rules layer is built on D&D 5e SRD (2014) content, covering character classes, spells, skills and combat, so players who know fifth edition will recognize the structure. AI Realm states that it is not affiliated with Dungeons and Dragons or Wizards of the Coast. AI Realm and its software are owned by AI REALM LLC or its licensors. The AI Game Master itself is powered by third-party AI services.
AI Realm Version 2 redesigned the Notes system around NPC Cards, a visual Character Sheet, custom sheet design and auto-updating notes. AI Realm reports 766K+ campaigns created and 22K+ Discord community members (company figures, as captured on October 5, 2026). A third-party AI tool directory estimates 786.0K monthly visitors to the site, also as captured on October 5, 2026.
AI Realm's feature set is organized around one idea: the campaign state lives in Notes, and the AI reads whatever is enabled there. All enabled Notes content shares one context limit, which starts at 70,000 characters on the free plan and rises on higher plans; disabled items stay stored but do not count.
AI Realm suits players who want an AI dungeon master on demand and are willing to curate notes so the story stays consistent.
It is a weaker fit in a few cases:
AI Realm runs in the web browser on desktop and mobile.
AI Realm has a free plan, and creating an account does not require a credit card. Paid tiers are named Bronze, Platinum, Emerald and Obsidian, but their prices are not listed on AI Realm's public homepage, guides, roadmap or terms as of October 5, 2026. What the public documentation does publish is how each tier changes campaign capacity:
| Plan | Base context | Listed "With DeepSeek" | NPC Cards per chat | GM Guides per chat | Auto-update tier |
|---|---|---|---|---|---|
| Free | 70,000 chars | 98,000 chars | 25 | 25 | Standard |
| Bronze | 70,000 chars | 98,000 chars | 50 | 50 | Standard |
| Platinum | 80,000 chars | 112,000 chars | 75 | 75 | Standard |
| Emerald | 100,000 chars | 140,000 chars | 100 | 100 | Advanced |
| Obsidian | 150,000 chars | 210,000 chars | 200 | 200 | Advanced |
Hitting the NPC cap means deleting NPCs or upgrading before you can create new ones.
Premium models require a subscription, although everyone can browse the full model list. Each model card shows its cost per message, free or premium, and how many messages you have sent with it. The AI Guide Generator uses 1 message per generation, and the AI Data Assistant costs 1 normal message per use. Lifelike text-to-speech has its own allowance, with remaining characters shown under Account.
Refunds may be granted depending on the reason but are not guaranteed, and unless the law requires otherwise, all purchases on AI Realm are final.
The closest comparisons are other AI game masters built on 5e-style rules and open-ended AI story games; group size and how combat is presented separate them most clearly.
