04Who is it for? When not to use it?
Good for
- DeepSeek Harness users who want to manage reusable prompts across the Harness web UI and other AI sites
- Researchers juggling dozens of threads, developers saving code snippets, and anyone who wants ordered AI chat history
Not for
- For Gemini for Enterprise, Prompt Manager is the only supported feature — folders, export, timeline and other features do not apply.
05Compatibility, maintenance and safety notes
- For Gemini for Enterprise, Prompt Manager is the only supported feature — folders, export, timeline and other features do not apply.
- Safari is not distributed through a store — you must download the Safari package from GitHub Releases; Safari cloud sync uses iCloud instead of Google Drive.
- The DeepSeek Harness integration is at the browser-UI level: Voyager injects its Prompt Manager into the Harness web page via the extension, so it does not touch the dsh CLI or agent runtime — inferred from the README, which only shows the localhost:3080 web UI.

06Frequently asked questions
How does Voyager work with DeepSeek Harness?
Voyager connects at the browser-UI level, not via dsh CLI or MCP: add the DeepSeek Harness site in the extension popup and the Prompt Manager follows you there. The README shows it running inside DeepSeek Harness on localhost:3080.
How do I install Voyager?
Install from the Chrome Web Store, Edge Add-ons, or Firefox Add-ons; the Safari package is downloaded from GitHub Releases. Manual installation and development builds are covered in the Installation Guide at voyager.nagi.fun.
Which features work on DeepSeek Harness?
The Prompt Manager is the feature shown working inside DeepSeek Harness. The Gemini-exclusive suite (folders, timeline, export, Mermaid rendering) targets Gemini / AI Studio, with extra plugins for Claude and ChatGPT.
Where do my prompts and folders sync?
Optionally through Google Drive (or iCloud on Safari) via Cloud Sync. Without cloud sync, data stays in the extension's local storage.
