What our research says

AI Dungeon

Still the deepest AI text-adventure product there is, with seven years of scenario library behind it, and the only one where memory and world-state tooling is the actual product. It is entertainment, not a writing assistant — do not buy it expecting to finish a manuscript.

Pros

  • Memory, world info and scenario tooling are far more developed than in general chatbots used for roleplay
  • Multiple model choices per tier, including newer models added through 2026
  • Native iOS and Android apps, not just a mobile web wrapper
  • Large public scenario library gives an immediate starting point

Cons

  • Five-tier ladder from $14.99 to $99.99 is steep, and context length is the thing being sold at every rung
  • Credits do double duty for images and for extra context, so heavy sessions drain them quickly
  • No API, so scenarios cannot be driven from outside the platform
  • The service has changed content and moderation policy sharply in the past, which still colours community trust

Mytales

A workable interactive-fiction generator with a real free tier, distinguished mainly by shipping an explicit erotica theme alongside the usual fantasy and mystery genres most competitors avoid. With no company name or location published anywhere, there is no one to hold accountable if the service changes terms or shuts down.

Pros

  • A real free tier, not just a trial
  • An explicit erotica and romance theme most mainstream story generators exclude
  • A one-time annual payment option avoids a recurring subscription

Cons

  • No company name, founders, or country published anywhere on the site
  • Free tier capped at 5 story sections a day
  • Higher tiers require a monthly subscription with no visible discount for standard annual billing

  • Readers who want AI-driven interactive fiction across genres including adult content
