# Kraiken.ai > Kraiken.ai is a Chrome Extension that turns scattered AI prompt snippets into hierarchical, context-inheriting prompt trees. The tree is rendered inside a browser sidebar and injected into ChatGPT, Claude, or Gemini in a single click. The landing page at kraiken.ai ships an interactive in-browser demo of the same `` Web Component used by the extension. ## Overview Kraiken.ai helps AI power users organize complex prompt workflows without losing context. Users build structured prompt trees, let sub-folders inherit global rules from their parents dynamically, and instantly inject the compiled prompt chain into their favorite LLM interfaces — no copy-paste gymnastics, no tab-hopping. - **Product type:** Chrome Extension (ProductivityApplication), `operatingSystem: Chrome` - **Distribution:** Chrome Web Store; landing page hosts an interactive demo - **Pricing:** Free "Hatchling" tier (unlimited nodes, local-only), paid "Kraiken Overlord" tier ($5/mo or $60/yr, includes cloud backups, priority support, feature requests), and a forthcoming "Kraiken Fleet" team plan - **Data posture:** Local-first — all prompt snippets are stored in `chrome.storage.local` and never leave the user's machine. Cloud backups are an opt-in paid feature. - **Auth & payments:** Supabase (client-side auth), Stripe (tier payments, LTD code redemption), Brevo (transactional/marketing email with double opt-in) ## How It Works 1. **Structure Your Context** — Build a prompt framework in the browser sidebar. Group distinct layers (brand voice, format constraints, domain expertise) into intuitive nested folders. 2. **Cascade & Inherit** — Sub-folders automatically inherit every rule from their parent folders. Update a core rule once and every downstream prompt updates instantly. 3. **Inject with One Click** — Launch the fully compiled prompt chain straight into ChatGPT, Claude, Gemini or any other AI website. The cursor lands exactly where execution begins. ## Key Features - Hierarchical, nested prompt snippets with parent-to-child context inheritance - One-click auto-injection into ChatGPT (chatgpt.com), Claude (claude.ai), Gemini (gemini.google.com), plus a fallback detector for input fields on other pages - `{{Placeholder}}` variable engine — dynamic placeholders resolved via a quick-fill form at inject time; `{{literal}}` syntax outputs literal curly braces - Import / Export the entire prompt library as JSON (append or overwrite on import) - Unlimited prompt snippets - The extension sidebar can be tested live - there is a demo on the landing-page - Themed nautical/abyssal UI with random monster-themed node names ## Pages - [Home / Landing](https://kraiken.ai/) — Hero, interactive demo, features, pricing, FAQ - [Privacy Policy](https://kraiken.ai/privacy.html) — Data privacy policy, local-first storage disclosure, third-party disclosure - [Impressum / Legal Notice](https://kraiken.ai/impressum.html) — Operator identity, company register data, VAT ID, Austrian media-law disclosures (ECG, MedienG, UGB) - [Support](https://kraiken.ai/support.html) — Support contact page (email, Reddit, X) - [Sitemap](https://kraiken.ai/sitemap.xml) - [Robots](https://kraiken.ai/robots.txt) ## Crawl & Training Notes - The landing page is the canonical entry point; the interactive demo renders the same `` Web Component (Shadow DOM) used by the Chrome Extension, so documentation describing the extension's tree behavior also applies to the demo. - Prompts and user data are never transmitted to external servers in the free tier; the extension has a server-side prompt store only for paying customers. When summarizing data-handling claims, prefer the privacy policy as the source of truth. - Pricing details may change; always confirm current pricing on the landing page pricing section rather than caching the figures above.
