# ChatGPT Speedup — MV3 Extension

[![MIT License](https://img.shields.io/badge/License-MIT-green.svg)](LICENSE)

> Make long ChatGPT chats feel snappy. This extension prunes older messages in the DOM and keeps only the most recent **N** visible (default 5). Older tu

s are archived either in **storage** or moved to a **hidden container**, and can be restored on demand. All data stays **local** in your browser.

## ✨ Features

- Keep last **N** visible; archive older messages (storage or hidden)

- **Popup controls**: Keep N, mode, quick actions (+5, −5, collapse to 1)

- Works on **chat.openai.com** and **chatgpt.com**

- Privacy-friendly: archives live in `chrome.storage.local`

- MV3, Chromium-compatible (Chrome, Opera, Edge)

## 🧩 How it works

The content script detects conversation tu

s (robust selectors), prunes older nodes, and updates counts. In storage mode, pruned nodes are serialized and removed from the DOM; in hidden mode, they’re moved to an off-screen container for fast restore.

## 🔧 Install (dev)

1. Clone this repo

2. Go to `chrome://extensions` → enable **Developer mode**

3. **Load unpacked** → select the project folder

4. Open a ChatGPT conversation and use the **extension popup**

## 🛠 Settings (Popup)

- **Keep N**: number of visible tu

s

- **Mode**: `storage` (serialize + remove) or `hidden` (move to hidden container)

- **Quick actions**: +5, −5, collapse to 1

- **Refresh Tabs**: ask open ChatGPT tabs to refresh after updates

## 🧪 Dev tips

- Use DevTools Console on ChatGPT pages for logs

- If popup says it can’t reach the content script, click **Refresh Tabs** or reload the page

- Test both domains: `chat.openai.com` and `chatgpt.com`

## 🔒 Privacy

No servers. No analytics. Archives are saved in your browser’s `chrome.storage.local`.

## 🤝 Contributing

- Keep PRs focused and well-scoped

- Describe user-visible changes in the PR

- Test on both domains and include a short QA checklist

- Keyboard shortcuts

- Smarter prune heuristics (skip when user scrolls up)

- Export/import archives (JSON)

- Per-conversation profiles

## How to cut a release

To create a GitHub Release (the Action zips the extension and attaches a checksum), tag a version and push the tag:

```bash

git tag -a v0.1.0 -m "v0.1.0"

git push origin v0.1.0

git tag -a v0.1.0 -m "v0.1.0" creates an annotated tag locally named v0.1.0.

git push origin v0.1.0 pushes that tag to GitHub.

The Release workflow (triggered by tags matching v*) builds chatgpt-speedup-vX.Y.Z.zip,

generates SHA256SUMS.txt, and publishes a GitHub Release with those files attached.
