About SinStories

SinStories is an AI story writer for adult fiction that generates erotica from a typed idea and plays interactive stories the reader steers with choices. Prompts are limited to 500 characters, finished text can be read aloud in an AI voice, and stories can be published to a community section under a pen name or anonymously. Sign-in uses an email one-time code, and the site shows an 18+ gate before any content loads.

Billing is credit based, as of October 2026. The free plan gives 5 credits per week; the weekly plan is $5.99 with 80 credits per week, the monthly plan is $14.99 with 150 credits per week and the yearly plan is $149.99 with the same 150 weekly credits. Paid plans also unlock additional AI models, and purchased top-ups do not expire.

The terms describe all output as fiction involving consenting adult characters and prohibit sexualizing minors, presenting non-consent as real and targeting real, identifiable people. One restriction worth knowing is ownership: the terms say every story and recording belongs to SinStories, and users receive a personal, non-exclusive license rather than ownership.
