Gemini Chat Exporter

Download the current Google Gemini conversation as JSON.

Gemini Chat Exporter lets you download the Google Gemini conversation currently open in your browser as a clean, structured JSON file. Use it to back up important conversations, preserve research and technical discussions, archive project notes, search your chat history with your own tools, or reuse conversations in scripts, databases, note-taking applications, and other AI workflows. Important: Gemini conversations may contain private, professional, or confidential information. For that reason, the complete extension source code is publicly available for inspection at: https://github.com/AshtonIzmev/gemini-chat-exporter-chrome-extension Using the extension is simple. Open a Gemini conversation, click the Gemini Chat Exporter icon, then click “Download current chat.” The JSON file is saved directly to your normal Downloads folder. Each export contains the conversation title, source URL, conversation identifier, export date, user prompts, and Gemini responses. Messages are provided as readable plain text and sanitized HTML, preserving useful formatting such as headings, lists, links, tables, and code blocks. Privacy is a central design goal. Your conversation is processed locally inside your browser and saved directly to your computer. The extension does not upload your chat, send it to the developer, store it on a remote server, collect analytics, display advertising, or track your browsing activity. The extension only reads the active Gemini conversation after you explicitly click the download button. It does not run continuously in the background and does not request permanent access to Gemini or every website you visit. Only three permissions are requested. activeTab provides temporary access to the page you selected. scripting runs the local conversation extractor. downloads saves the JSON file requested by you. The repository contains all runtime code, the permission manifest, automated tests, the privacy policy, the security threat model, public security checks, reproducible packaging tools, release checksums, and a ready-made prompt you can give to your own trusted LLM for an independent security review. Users who want maximum control can download the source, review the exact files, and install their reviewed copy using Chrome’s “Load unpacked” feature. This makes it possible to verify exactly what Chrome executes instead of relying only on a store description or privacy promise. The project uses automated tests, CodeQL analysis, dependency auditing, permission checks, and checks for unexpected network access, remote code, persistent storage, tracking, and sensitive browser APIs. These checks improve transparency but do not guarantee that any software is perfectly secure. Users are encouraged to review the public source and decide whether the requested permissions are appropriate for their needs. The extension currently exports rendered user prompts and final Gemini responses. Attachments, generated media, thinking traces, tool traces, alternate drafts, source panels, and individual message timestamps are not currently included.
