Gemini Toolbox: Watermark Remover & Search
Extension Actions
Gemini search, watermark remover, export chats to TXT, Markdown, JSON, PDF. Find conversations and clean AI images instantly.
Three things Google Gemini is missing: full-text search across your chats, watermark-free image downloads, and export to the format you actually use.
FULL-TEXT CONVERSATION SEARCH
The built-in Gemini search only matches conversation titles, so anything you or the AI wrote is effectively lost once a thread scrolls out of view. This extension indexes the full body of every message, prompts and answers, so you can recall any word or phrase from months-old threads in seconds.
- Keyword and exact-phrase matching across your entire chat history
- Filter by role (your prompts, AI responses, or both)
- Filter by date (any time, past week, past month, past year)
- Exact-match toggle to stop partial-word hits
- Results grouped by conversation with highlighted matches and expandable previews
- Match count and response time on every query
- Recent queries surface as one-click pills for instant reuse
- Cmd+Shift+F (Mac) or Ctrl+Shift+F (Windows) opens search from anywhere in the app
IMAGE DOWNLOADS WITHOUT THE WATERMARK
Every picture generated in Gemini's web UI ships with a visible sparkle logo stamped in the bottom-right corner. This extension removes it losslessly using reverse alpha blending, a mathematically exact method that reconstructs the original pixels with zero quality loss and no AI inpainting or hallucination.
- Works on every output size, aspect ratio, and resolution (up to 4K+)
- 100% lossless: pixels outside the stamped area are preserved byte-for-byte
- 100% local: images are never uploaded, processing runs in your browser
- Zero extra clicks: use the native download button and the saved file is already clean
- Preserves the original resolution and format
- Built on Allen Kuo's open-source pre-calibrated alpha masks (MIT licensed)
EXPORT ANY CHAT
Save any thread locally in the format you need:
- TXT: plain text with clear role labels
- Markdown: formatted headers and separators, ready for any notes app
- JSON: structured data with full metadata, suited for developers and automations
- PDF: A4 document with color-coded roles, page breaks, and page numbers
A one-click export button appears next to the native share button in every thread. No modal chains, no copy-pasting, no lost formatting.
PRIVACY
Your history is cached locally in IndexedDB so lookups are instant. Nothing is ever uploaded. Watermark processing runs on your device. Export processing happens in the browser. Your data never leaves your machine. GDPR compliant.
COMPATIBILITY
Works on gemini.google.com across Chrome, Edge, Brave, and Opera. Compatible with every model and every image generation feature. Handles multi-account Google sessions (/u/0, /u/1, etc).

- Gemini Toolbox - Finally, I can actually find what I’m looking for I use Gemini a lot, and the built-in search was always a weak point because it only looked at titles. This extension fixes that problem perfectly. What really works for me: Full-text search: This is the most important feature. It finds specific keywords deep inside old conversations from weeks ago in seconds. Smart filters: You can narrow results down by date or choose to search only within your questions or Gemini’s answers. It cuts out all the "noise." Clean exports: Being able to save a chat as a styled PDF or Markdown (perfect for those using Notion) is essential for documenting work. Privacy: A big plus - all data stays local in your browser and isn't sent to any external servers. Quick shortcut: Just hit Ctrl+Shift+F and it opens up. Simple and fast. The bottom line: A lightweight tool that cleans up the mess and turns Gemini into a much more professional workspace. Highly recommended if your chat history is getting too long to manage.
