DirDiff
yoy.be
DirDiff started as a tool to check two copies of files in separate directories, either by date or by a different modified date. From there, we had a go at building our own text-diff. Other diff's show the content of both files, and thus show the content that is equal twice. Sounds like a lot of wasted screen-space, so we show a single 'flow' and the different parts in different colors. Yes, we know we might have got green and red reversed, but since we use diff primarily to check what we've changed before commit, We like them to show up in red because it draws attention. It can also show the structure of XML documents in a tree view. If you configure the usual attribute names that holds identifying values, it will use those to show the relevant changes. If you're using TortoiseSVN, it turns out to be a good alternative diff to use with TortoiseSVN, open the settings and enter the command provided in our site for the external Diff Viewer. -

The goal in a future version is to introduce the comparison step directly into the beautifiers between the parse step and the beautification step to become a truly language-aware code comparison and analysis tool. The code comparison mode is the default mode and the only mode to require two code samples. Pretty Diff has progressively moved from community-driven dependencies to custom parsers to accomplish code beautification for a diversity of features and requests. Each of Pretty Diff's beautification libraries has a minify feature. -

Morph Fast Apply
Morph
Morph FastApply is a specialized AI infrastructure tool designed to dramatically improve how AI coding agents edit and update source code. Instead of rewriting entire files or relying on fragile search-and-replace operations, FastApply merges AI-generated code changes directly into existing files using a semantic understanding of the code structure. It works by allowing an AI model to output only the relevant modifications to a file while marking unchanged sections with placeholders. The FastApply model then merges those changes server-side, reconstructing the complete updated file while preserving formatting, syntax, comments, and dependencies. This approach significantly reduces the number of tokens required and eliminates many of the errors caused by traditional diff-based or search-and-replace editing methods. It processes edits at speeds of over 10,500 tokens per second with approximately 98% accuracy.Starting Price: $20 per month -

Kuku
Kuku is a native macOS note-taking and knowledge management app that combines a lightweight Markdown editor with modern AI-driven tools while keeping your files as plain .md on your disk so they remain accessible by editors like vim, versionable with git, and free from cloud vendor lock-in. It supports bidirectional links with autocompletion and backlinks panels that help you interconnect ideas, plus a graph view for visualizing relationships between notes. It includes an AI agent powered by Gemini with a tool that can search your local vault, read files, generate summaries, and create or edit documents with cursor-style edit previews that show suggested changes as diffs before you accept or reject them. Kuku also offers local Whisper speech-to-text for offline audio transcription, fast full-text search using SQLite FTS5 with BM25 ranking, and a native performance footprint built on Tauri that results in a small installation and low memory usage without Electron overhead.Starting Price: $12 per month -
