What it solves

Timeline addresses the difficulty of managing long conversations with AI chatbots. It solves the problem of having to scroll endlessly to find previous questions, losing valuable insights across different sessions, and the difficulty of exporting or copying complex content like formulas and code blocks from AI platforms.

How it works

It is a browser extension that overlays additional productivity tools onto existing AI chat interfaces (such as ChatGPT, Gemini, and DeepSeek) without altering the original UI. It provides a navigation timeline on the right side of the page, a prompt library, and data management tools that save information locally or sync via Google Drive.

Who it’s for

Users who engage in long, complex interactions with AI platforms and need a way to organize, archive, and quickly navigate their chat histories.

Highlights

• Timeline Navigation: Generates a clickable timeline of user questions for fast jumping within long chats.
• Organization Tools: Includes a prompt library, favorite folders, and the ability to archive specific Q&A pairs or entire sessions.
• Reading & Export: Supports LaTeX/MathML formula copying, Mermaid chart previews, and code block execution for various languages (JS, TS, SQL, etc.).
• Broad Compatibility: Works across a wide range of platforms including ChatGPT, Gemini, DeepSeek, Claude, Kimi, and others.
• Data Portability: Supports JSON import/export and Google Drive backups for multi-device synchronization.
