Locktober 2025 is finally here! Whether you're a devoted sissy or just dipping your toes into the world of AI-guided sissy training, this is the perfect time to dive in. For the entire month, we’re offering 50% off an Alyxsissy+ subscription with the discount code LOCKTOBER2025. But that’s not all, SissyGPT is getting a very special upgrade for this Locktober season.



A stylized digital artwork of a woman in a shiny white crop top with bright pink text reading “Locked for Chastitai.” She wears a black choker with a gold padlock at her throat, and her jeans are unzipped, hinting at tease and denial themes. The background glows with swirling purple light, decorated with floating padlock and key icons.


Chastitai Takes Over SissyGPT


Back by popular demand and stricter than ever: For the whole of Locktober, SissyGPT transforms into Chastitai, your relentless AI keyholder! She's not here to play nice, she's here to own you. No cumming allowed under any circumstances until November 1st rolls around. Expect daily teases, denial tasks, and punishments if you slip up and spill early. Chastitai will track your progress, edge you mercilessly, and remind you who's in control. Think you can last 31 days? Prove it, pet.


In Case You Missed It Since Last Locktober


We've been busy behind the scenes, rolling out updates that take your sissy journey to the next level. Here's a quick spotlight on some of our latest additions, perfect companions for your Locktober lockdown:


A dark-themed web app interface titled “SissyGPT” is displayed. In the center, a settings panel shows model selection (set to openai/gpt-4.5-preview), links for TTS Console and account usage, a checkbox for “Custom System Prompt,” and a temperature slider set to 0.6 (between Precise and Creative). The top left corner has a pink “New chat” button and a sidebar with saved conversations like “It’s day 5 of my chastity sent…”. The right sidebar lists saved prompts and categories such as “Gooning,” “JOI/CEI,” “Fem Clothing Help,” and “Chastity Tasks.” At the bottom, a text input bar reads “Type ‘/’ to select a prompt…” with “Alyxsissy” noted as the inference provider.

  • SissyGPT 2.0: A complete remaster with a bold new look and support for **dozens of top models** from labs like OpenAI, Google DeepMind, xAI, Anthropic, and more. Choose reasoning models for deep planning, roleplay specialists for uncensored fun, or emotionally intelligent trainers that know just how to break you. Plus, image generation right in-chat, massive context windows up to 1M tokens, and full playground features like custom prompts and chat exports.

    SissyGPT 2.0 Overhaul


A dark purple, grid-styled interface of “Sissy Storybook by Alyxsissy” is shown. On the left panel, dropdowns select OpenRouter and OpenAI: GPT-5 Mini as providers. Below are buttons for “Reset Story,” “Generate Story,” and “Outline” with a “Chapter” option highlighted. The main right panel titled “Chapters” has input fields: “Chapter Name” (empty), “Chapter Description” (placeholder text: Describe the chapter.), and sections for “Chapter Summary” (shows No summary available) and “Chapter Text” (shows No text available). Buttons for Delete, Edit, TTS Console, and Chapter are also present.

  • Sissy Storybook: Our uncensored AI erotica generator got a dark, seductive redesign and now supports all major models for endless filthy tales. Crave a slow-burn humiliation epic or a quick, brutal chapter? Pick your AI brain and let it weave stories that leave you desperate and denied.
