Local archival tool for Gemini conversations and generated media
gemini-collector, from FirenzeLor, is a native Windows utility that creates local backups of Google Gemini conversations for long-term preservation. The app synchronizes chat histories and attachments to local storage using a zero-config model with resumable transfers and incremental updates. Its interface supports timeline navigation, export filters, and theme switching. Power users, researchers, and AI hobbyists get a private, searchable archive separate from cloud-based exporters.
Archives conversation artifacts as structured, exportable files
The app writes archived content to local files and preserves AI-generated media alongside text, which means conversations and attachments are captured as discrete artifacts for later analysis. It saves conversation data in JSON and downloads user-uploaded attachments plus generated images, music, and video, making exports usable for scripting or academic workflows. Export options include time-range filtering and a timeline view for locating specific periods quickly.
Handles large histories with native synchronization and resumable transfers
The Windows build runs as a native application, which the developer says improves handling of thousands of conversations compared with browser extensions. Incremental updates mean the tool requests only new or changed items since the last sync, and resumable transfers let interrupted downloads continue without restarting. The sign-in flow uses a built-in WebView2 browser and local cookies to permit automatic synchronization after authentication.
Keeps data local and isolates multiple accounts for privacy
The app follows a local-first privacy model: all synchronization and storage occur on the user's machine and no data is uploaded to the developer or third parties. Multi-account support places each account in an independent data silo, so personal and professional profiles remain separated. Community feedback highlights the utility for preventing loss when hosted chat histories are removed.
Zero-configuration entry, with features suited to technical users
The tool targets power users by combining a one-click sync experience with advanced rendering, including Markdown, LaTeX math, and syntax-highlighted code. The native interface switches themes automatically and exposes timeline navigation plus export filters, which lowers setup friction while keeping controls available for scripted or research-oriented workflows. The developer's Windows release followed an initial macOS version, reflecting active maintenance.
Recommended for users who need private, local archives with trade-offs
gemini-collector is a practical option for power users and researchers who need persistent, machine-readable backups of AI conversations. Its trade-off is a desktop-focused workflow that requires local storage management for media-heavy histories. For routine use, schedule synchronizations during idle hours to avoid network contention. Recommended.
Pros
Saves conversation text and AI-generated media to local JSON files
Supports incremental updates and resumable transfers for large archives
Multi-account management keeps profiles in independent local silos
Cons
Local archives require managing disk space for media-heavy histories
Uses WebView2 and local cookies for sign-in and sync
