02How to install into DeepSeek Harness
Prerequisites
- A Chromium (Chrome / Edge) or Firefox browser for the browser extension
- For DeepSeek Harness support: a DeepSeek Harness install plus the separate companion plugin `dsh-timeline`
Installation steps
- 01
Install the browser extension from the official store (Chrome Web Store, Microsoft Edge Add-ons, or Firefox Add-ons), or load the unpacked source directory for local development
- 02
Open a supported AI chat page (ChatGPT, Gemini, DeepSeek, …) and the features activate automatically
- 03
DeepSeek Harness users: install the companion native plugin `dsh-timeline` from https://github.com/houyanchao/dsh-timeline (this repo documents dsh support, but the dsh plugin lives in that separate repo)
Verify the integration
- After installing, open a supported AI chat page and confirm the right-side timeline of questions appears and features are usable
03DSH integration and capability boundaries
Timeline is a browser extension for AI chat web pages (ChatGPT, Gemini, DeepSeek and 10+ platforms). Its README states DeepSeek Harness is now supported via a companion native dsh plugin `dsh-timeline` (a separate repo, houyanchao/dsh-timeline) that brings the timeline, favorites, prompt library, conversation export and formula-copy into dsh. This repo itself is the browser-extension codebase, not a dsh plugin.
Conversation timeline navigation
a supported AI chat page (ChatGPT, Gemini, DeepSeek, …)→a right-side timeline where each node is one user question, with click-to-jump, keyboard navigation, back-to-bottom and question-time labels
Favorites, folders & prompt library
individual Q&A or whole sessions on the chat page→favorite single answers or entire sessions, organized with folders, notes and search; plus a reusable prompt library and quick follow-up input
Formula & code copy / run
LaTeX / MathML, Mermaid diagrams and code blocks in the chat→copy LaTeX / MathML formulas, preview Mermaid diagrams, and run or preview code blocks (JavaScript, TypeScript, SQL, HTML, JSON, Markdown)
Data backup & export
the extension's local data (favorites, folders, prompts, settings, notes)→JSON import / export and optional Google Drive backup & restore for migration and multi-device sync
04Who is it for? When not to use it?
Good for
- Heavy AI-chat users who re-read long conversations and want quick navigation, save and export without leaving the page
- DeepSeek Harness users who want the same timeline / favorites / prompt-library workflow in the harness
05Compatibility, maintenance and safety notes
- This repo is a browser extension (Manifest V3) for Chromium / Firefox. The DeepSeek Harness features require the separate companion plugin `dsh-timeline` (houyanchao/dsh-timeline); they are not built into this browser-extension codebase.
- Core data is stored locally in the browser by default. The optional Google Drive sync is only used after the user explicitly authorizes it, for backup / restore. The extension does not collect, upload or share conversation content or personal information.
- Released under GPL-3.0 (copyleft). Derivative or redistributed works must also be licensed under GPL-3.0; the source is open for review in the repository.
GPL-3.0 · actively maintained (no tagged release in this repo; distributed via browser stores; companion dsh-timeline plugin available)
06Frequently asked questions
How do I install Timeline?
Install the browser extension from the official store (Chrome Web Store, Microsoft Edge Add-ons, or Firefox Add-ons), or load the unpacked source directory for local development. Most features are on by default once you open a supported AI chat page.
Which AI platforms are supported?
13 platforms including ChatGPT, Gemini, DeepSeek, Claude, Kimi, Doubao, Qwen, Grok, Perplexity, Yuanbao, Wenxin, NotebookLM and others — timeline, highlight, smart input and follow-up work across them; some features vary by platform.
Does it work with DeepSeek Harness?
The README says yes — via a companion native dsh plugin called `dsh-timeline` in a separate repo (houyanchao/dsh-timeline). This repo is the browser-extension codebase; the dsh plugin itself lives in that other repo, so install `dsh-timeline` for in-harness use.
Is my chat data private?
Core data is stored locally in your browser by default. Google Drive sync is used only after you explicitly authorize it (for backup / restore). The extension does not collect, upload or share your conversation content or personal information.
What can I actually do with it?
Navigate long chats via a question timeline, favorite and organize Q&A with folders, reuse a prompt library, export conversations, copy LaTeX / MathML formulas, preview Mermaid diagrams, run code blocks, and back up data to JSON or Google Drive.
