  📅 Chat Timeline – See When Every Conversation Happened
  
  Ever tried to find a conversation from last week in your AI chat history — and realized there are no dates anywhere?
  
  Chat Timeline fixes that.
  
  This extension automatically displays clear, readable timestamps for every conversation in your sidebar, so you always know exactly when a chat happened.
  
  
  🎯 What It Does
  
  Chat Timeline adds date and time information above each conversation in your ChatGPT sidebar. No more guessing which chat was from yesterday and which was from last month — now you can see it instantly.
  
  
  ✨ Key Features
  
  📆 Automatic Timestamps
  Dates appear above each conversation title automatically — no clicks or setup required.
  
  🕐 Smart Date Formatting
  See time in a human-friendly way: "Just now", "2 hours ago", "Yesterday", or "Dec 15, 2024" for older chats.
  
  🌙 Dark Mode Support
  Seamlessly adapts to light and dark themes to match your ChatGPT interface perfectly.
  
  ⚡ Lightweight & Fast
  Zero performance impact. The extension runs quietly in the background without slowing down your browser.
  
  🎨 Fully Customizable
  Choose your preferred date format (Smart, Relative, or Absolute) and adjust font size to your liking.
  
  🔄 Auto-Updating
  Timestamps refresh automatically whenever your conversations update — always accurate, always current.
  
  
  📅 Choose Your Date Format
  
  Smart Mode (Recommended)
  Shows relative time for recent chats and full dates for older ones:
  → Just now · 2h ago · Yesterday · Dec 15, 2024
  
  Relative Mode
  Always shows how long ago:
  → 2h ago · 5d ago · 3mo ago · 1y ago
  
  Absolute Mode
  Always shows the exact date:
  → 15 Dec 2024
  
  
  🔒 Your Privacy Matters
  
  We take privacy seriously. This extension:
  
  ✅ Collects NO personal data
  ✅ Uses NO tracking or analytics
  ✅ Sends data to NO external servers
  ✅ Runs 100% locally in your browser
  
  Your conversations are never read or accessed. The extension only displays timestamp information that already exists on the page — we simply make it visible to you.
  
  
  💡 How To Use
  
  Step 1: Install the extension from Chrome Web Store
  Step 2: Visit chat.openai.com or chatgpt.com
  Step 3: Log in to your account
  Step 4: Timestamps appear automatically in your sidebar
  
  That's it! No configuration needed. It just works.
  
  Want to customize? Click the extension icon in your toolbar to change date format, font size, or refresh data manually.
  
  
  🛠️ Permissions Explained
  
  We believe in full transparency:
  
  → Site Access 
  Required to inject timestamp elements into the conversation sidebar.
  
  → Storage
  Used only to save your preferences locally on your device. Nothing is uploaded anywhere.
  
  
  ❓ Common Questions
  
  Q: Does this extension read my conversations?

  Q: Does it work on mobile?
  A: No. This is a desktop Chrome extension for the web version only.

  A: Yes — completely free with no hidden costs, subscriptions, or premium features.
  
  Q: What if timestamps aren't showing?
  A: Make sure you're logged in to ChatGPT, then click the extension icon and press "Refresh". If the issue continues, try refreshing the page.

  📅 Chat Timeline – See Exactly When Every AI Conversation Happened
  
  Tired of scrolling through your ChatGPT history with no idea when a conversation happened? Can't tell if that chat was from last week, last month, or last year?
  
  Chat Timeline fixes that instantly.
  This extension automatically displays clear, readable date timestamps above every conversation in your ChatGPT sidebar — so you can find any chat in seconds without guessing.
  
  🎯 What It Does
  Chat Timeline reads the real creation and last-update timestamps for each conversation directly from the ChatGPT interface and displays them as neat, color-coded badges above every chat title. No configuration required — install and it just works.
  
  
  ✨ Key Features
  📆 Automatic Date Stamps
  Timestamps appear automatically above every conversation in your sidebar. No clicks, no setup. Works as soon as you open ChatGPT.
  📅 Show When a Chat Was Created
  See the exact date your conversation was first started — not when it was last replied to. This is the real creation date, displayed accurately for every chat.
  ↻ Show When a Chat Was Last Updated
  Prefer to know the last activity date? Switch to "Last Updated" mode to see when each chat was most recently replied to or renamed.
  📅 + ↻ Show Both Dates Simultaneously
  Enable "Both" mode to display two stacked badges per conversation — one green badge for the creation date and one blue badge for the last updated date. Never lose context again.
  
  🕐 Three Date Format Modes
  Choose the format that works for you:
  → Smart Mode (recommended): Relative for recent chats, full date for older ones — "Yesterday · 22 Apr 2026", "15 Jan 2026"
  → Relative Mode: Always shows how long ago — "38d ago", "3mo ago", "2y ago"
  → Absolute Mode: Always shows the full date — "15 Jan 2026" (year always included)
  
  🌙 Full Dark Mode Support
  Seamlessly adapts to light and dark themes to match your ChatGPT interface perfectly.
  
  ⚡ Lightweight & Fast
  Zero noticeable performance impact. The extension runs quietly without slowing down your browser or ChatGPT.
  
  🎨 Customizable Badge Size
  Choose Small, Medium, or Large badge size — whatever fits your screen and preference.
  
  🔄 Auto-Refresh & Smart Caching
  Timestamps refresh automatically. A built-in cache means fast loading on repeat visits. Hit "Refresh" in the popup anytime to force a fresh data fetch.
  
  ⚡ Instant Settings Change
  Switching between date formats or date types (Created / Updated / Both) instantly re-renders all badges — no page reload needed.

  🛠️ Permissions Explained
  We believe in complete transparency:

  → Tabs
  Used to instantly apply setting changes (like switching date format) to your open ChatGPT tabs without requiring a page refresh.
  
  
  ❓ Frequently Asked Questions
  Q: Does this extension read my conversations or messages?
  A: Absolutely not. The extension only accesses timestamp metadata — specifically when a conversation was created and when it was last updated. Your actual chat messages are never read, accessed, or stored in any form.
  
  Q: Will this slow down ChatGPT?
  A: No. The extension uses smart caching and only injects lightweight visual elements. Performance impact is negligible.
  
  Q: Where does the date data come from?
  A: The extension reads timestamp information from the ChatGPT interface that is already available during your logged-in session — the same data your browser already has access to when you use ChatGPT.
  
  Q: Does it work on mobile?
  A: No. This is a Chrome desktop extension for the web version of ChatGPT only.
  
  Q: Is it free?
  A: Yes — completely free. No subscriptions, no premium tier, no hidden costs.
  
  Q: What if dates aren't showing?
  A: Make sure you are logged in to ChatGPT. Then click the Chat Timeline icon and press "Refresh & Re-fetch Dates". If timestamps still don't appear, refresh the ChatGPT page and wait a few seconds.
  
  Q: Why do some badges look slightly different (italic or different color)?
  A: Green badges show the real creation date fetched from the API. Blue badges show the last-updated date. Italic badges are estimates based on ChatGPT's own sidebar date groups (shown while the real API data is loading).
