Free online text compare tool with real-time line-by-line and word-level diff highlighting. Text compare code, documents, and files side by side instantly.

I noticed that many people online were looking for a simple and effective way to compare text. Most existing tools either felt outdated or overloaded with features, and I personally always preferred the comparison experience in IntelliJ IDEA — it’s intuitive, clean, and easy to read at a glance. That inspired me to build a web-based text comparison tool that focuses on clarity and usability. I wanted something lightweight that people could open instantly in the browser without installing heavy software. The first version is intentionally simple and focused on plain text comparison. While building it, I realized there’s potential to expand far beyond that. My roadmap now includes support for comparing PDFs, Word documents, and other file formats, as well as advanced features like folder/directory comparison and even a desktop version for offline personal use. Throughout the process, my approach evolved from “just building a diff tool” into creating a modern comparison workspace that balances simplicity with powerful functionality.

The side-by-side layout with word-level diff highlighting feels really thoughtful, especially how it stays responsive even on smaller windows. Nice work on making something that simple actually feel polished to use.

@harlan_cronin Thank you! I really appreciate that. I wanted the comparison experience to feel as clear and intuitive as possible, so it's great to hear you noticed the layout and responsiveness.

I hope this tool proves useful to more people. If you spot anything that could be improved or have any suggestions, I'd love to hear them. Your feedback will help make it even better.
