FileConcat.com

FileConcat.com is a web-based tool that lets you combine multiple files into a single document. You can drag and drop files from your computer, upload folders, or import directly from GitHub repositories. The tool processes everything locally in your browser, meaning your files never leave your device. This makes it particularly useful for preparing materials to use with AI tools like ChatGPT or Claude, where you might want to analyze multiple files together.

The tool includes several practical features for technical workflows. It provides real-time token counting so you can stay within different AI models' context window limits. It automatically filters out binary files and other unnecessary file types that wouldn't be useful for text-based AI analysis. The GitHub integration allows developers to pull entire repositories directly into the tool without manual downloads.

FileConcat.com is most valuable for developers who need to share codebases with AI assistants for review or debugging, content creators combining multiple documents for editing, and researchers compiling papers or documentation. Since it works entirely locally and requires no registration, it's a simple, secure option for quickly preparing files for AI analysis without complex setup or data privacy concerns.
