AI Data Export File Format Fixer — clean up your AI chat exports for reuse

The problem we solve
--------------------
When you export your conversation history from AI chat tools like ChatGPT, Google
Gemini, Anthropic Claude, or xAI Grok, the download is often a bundle of cryptic
".dat" files instead of plain readable text. These files mix real conversation
text together with binary noise — audio clips, images, and other attachments —
so you cannot simply open them and paste your history into another AI chat. There
is no easy, private way to turn that messy export back into clean, usable text.

How it works
------------
1. You drop your ".dat" files (or a ".zip" archive that contains them) onto the page.
2. The tool reads each file directly in your browser. Nothing is uploaded to a server.
3. It detects the text encoding (UTF-8 or UTF-16, with or without a byte-order mark)
   and decodes the readable text, while automatically detecting and skipping binary
   and audio files such as MP3, WAV, OGG, FLAC, MP4/M4A, PNG, JPEG, GIF, PDF, and ZIP.
4. Each converted file is renamed using the first eight readable words of its content,
   so the output filenames are meaningful instead of random. Duplicate names are de-duplicated.
5. You download the cleaned ".txt" files one at a time, or all together as a single zip.

Features
--------
- Accepts multiple ".dat" files at once via drag-and-drop or file browsing.
- Accepts a ".zip" archive and extracts only the ".dat" files inside, ignoring everything else.
- Smart encoding detection for UTF-8 and UTF-16 text, including BOM handling.
- Automatic skipping of binary and audio files, with a clear reason for each skip.
- Automatic, human-readable file naming from the first eight readable words.
- Per-file download and download-all-as-zip.
- Light and dark mode.

Benefits
--------
- Completely private: all conversion runs locally in your browser, so your data
  never leaves your machine and there is no upload, account, or server storage.
- Free and offline-capable once the page has loaded.
- Turns unusable AI export bundles into clean text you can paste into any other
  AI chat, document, or note-taking tool.
- Fast, with no waiting on a server and no file-size limits beyond your own device.
