KleinValue Advisor

KleinValue Advisor delivers AI-powered item analysis for Kleinanzeigen

KleinValue Advisor adds an "Analyze with AI" workflow to every Kleinanzeigen listing so you can negotiate with data, not guesswork. Run Google Gemini, OpenAI GPT, Anthropic Claude, or Puter.js on the photos and details of any ad to receive an estimated fair price, confidence rating, reasoning, and cost transparency. Every analysis is stored locally so you can revisit insights from the popup, dashboard, or search overlays without re-running the model. WHY INSTALL KLEINVALUE ADVISOR? - Vision-first valuations: Uploads listing images plus description context to multimodal LLMs for richer price guidance. - Multi-provider studio: Switch between Gemini, ChatGPT, Claude, and Puter.js in one place, with per-provider model catalogs. - Puter.js quick start: No API key required, free usage quota included, and access to models from multiple underlying providers. - Inline UI on Kleinanzeigen: Adds a floating price badge beside the seller's number, including collapsible reasoning, confidence, and API cost. - Realtime bargain radar: Highlights listings you've already analyzed directly inside Kleinanzeigen search results. - Analytics dashboard: Browse a responsive grid with natural-language search, chip-based filters (price, AI value, good-value, date), inline reasoning tooltips, and quick open/remove actions. - Cost transparency: Surface estimated token counts and EUR-formatted pricing so you always know what each call costs. - Privacy-respecting: All data stays in Chrome storage on your device; nothing is uploaded to third-party servers beyond the AI providers you enable. WHAT YOU GET 1. Analyze button on each listing that fetches images, builds prompts, and sends them to your selected provider. 2. Popup recap with the last analyzed items, quick links to dashboard/settings, and active provider/model status. 3. Dashboard view for browsing history with natural-language search, chip filters spanning price/value/dates, inline reasoning reveals, and one-click open/remove controls. 4. Settings lab with provider management (including Puter no-key mode), image limits, temperature controls, and auto-analyze toggles. PERMISSIONS EXPLAINED - storage: persist analyzed items, provider selections, and API keys locally. - browsingData: used only for the optional "Reset Puter Auth" action in settings. - Host permissions (kleinanzeigen.de + AI APIs): needed to read listing data and call the AI endpoints you configure. No user analytics, payment collection, or background network requests occur beyond the explicit AI API calls you trigger.
