UltraCompare 2025.0 brings AI capabilities to your diff workflow and modernizes secure file transfer protocols.

Pieces AI integration

UltraCompare now includes the Pieces for Developers plugin, bringing AI assistance directly into your comparison workflow. This optional plugin adds a dockable chat window that understands the context of the files you’re comparing.

You can ask questions about changes, request summaries, or get help understanding complex diffs. The AI can:

  • Understand changes faster — Ask why a block changed, what a diff means, or whether it’s safe to merge
  • Summarize changes — Generate readable summaries for commits, PRs, or release notes directly from diffs
  • Spot bugs and risks — Review diffs for logic errors, edge cases, regressions, or security oversights
  • Resolve conflicts smarter — Get suggestions on which version to keep during merge conflicts

Choose your preferred LLM service including OpenAI’s ChatGPT, Google’s Gemini, or Anthropic’s Claude. Pieces is completely optional—install it only if it fits your workflow.

Updated FTP support and protocols

UltraCompare receives the same FTP protocol enhancements introduced in UltraEdit 2025.1:

  • Expanded cryptographic support with modern key exchange and signature algorithms, including ECDSA variants (ecdsa-sha2-nistp256/384/512)
  • Improved compatibility with current server requirements, adding rsa-sha2-256, rsa-sha2-512, ed25519, and chacha20-poly1305 cipher modes
  • More reliable connections, especially for environments with ED25519 requirements

What’s new in UltraCompare?

UltraCompare 2025.0 adds AI-powered comparison analysis with Pieces integration and expanded FTP protocol support for secure file transfers.

UltraCompare gets a revolutionary update in 2023. Some of the notable changes in this release are visual tweaks to the comparison interface, new folder compare options, and more granular control on how comparisons are executed.

It will also be the first major release that will make its way to the Windows and Mac versions of UltraCompare simultaneously.

The most prominent update will be the functional facelift of the tool’s main comparison panes. Careful thought has gone into deciding what needs to be updated and what would make the most sense in making compare merges much more intuitive.

Secondly, UC 2023 comes with a lot of new filter options and compare parameters. This includes new tweakable options to fine tune your compare and merge settings. These settings include adding time stamps parameters, new hash compares, and setting default session options. Most of these may come off as niche use cases but it is an indispensable addition to those that can use it, so try them out!

Lastly, this release comes with a number of tweaks and bug fixes based on your reports. For a complete list of QoL tweaks and bug fixes read our blog post.

UltraCompare 2022.20 released

If you merge text in UltraCompare, have you ever thought, “I wish this were faster…”? Yeah, us too.

That’s why we’ve pushed pause on installing new functionality in UltraCompare and turned our focus exclusively on making merging faster and more responsive than ever. We’ve re-tooled the text merge engine completely to provide lightning fast merge results. We’ve redesigned UltraCompare’s data handling to completely eliminate unwanted redrawing of compare panes and refreshing of compares so you can get your merges done as quickly and as nimbly as you expect.

UltraCompare 2022 also includes more granular merge settings for text and folder mode. Check out more belo

Improved merge settings

Want a prompt for folder mode merge but not text mode? You got it. The new Merge section in Settings provides you with more granular control over merge behavior.

Oh yeah, we threw in a few new application themes for you too.

Check out our three new themes with modernized colors. Just because you’re dealing with data doesn’t mean you can’t do it in style.

  • Prompt backup systems when a file is updated
  • Verify backups or automated sync processes

Text mode gets Quick Find, and merging in Just Differences view

One of UltraEdit’s handy features makes its way to UltraCompare. Quick find is a small search interface that provides a quick and easy-to-access search dialog accessible via Ctrl F.

Merging blocks in Just Differences mode is now also possible.

Improved look and features for Git

We’ve also implemented several improvements for  Git integration in UltraCompare.

  • Added sort by conflict and modified files
  • Option to hide remote branches
  • Revamped visual design for reviews and compares
Improved look and features for Git

Get more control with updated Binary Mode

Binary mode now supports hex offsets for both the beginning and end of the compare. This means that you can focus on specific portion(s) of the data you wish to compare, even if it doesn’t logically align. We’ve also added the ability to customize the number of hex bytes per line as well as go-to hex address, similar to UltraEdit.

There are several small changes that impact usability all throughout the application, as well as some quality issues being addressed. Read the documentation to see the complete list.
