Obsidian is a note-taking and personal knowledge management application by Obsidian.md that stores notes as local Markdown files. It provides features for linking notes (backlinks), a graph view, and a plugin system for extensibility across desktop and mobile.

YOINK is a Python terminal note-taking and forecasting tool that stores notes as plain Markdown files with Obsidian-compatible frontmatter and wikilinks. It adds claims, deadlines, confidence levels, machine-testable conditions, and data sources to notes; when a claim is due, `yoink settle` reads the source, applies the test, and writes the outcome and reading back into the note. Supported sources include local files, CSV values, public EVM-chain JSON-RPC readings, and manually recorded URLs. The terminal interface provides capture, search, link navigation, tags, graph views, claim settlement, and vault health commands. It recomputes the vault from disk without a database or index, and `yoink score` reports note activity, settled-claim accuracy, confidence gaps, and Brier scores. An append-only, hash-chained JSONL ledger records captures, reads, claims, and settlements; the project describes it as tamper-evident rather than tamper-proof. The repository states that it targets Python 3.10 or later, uses only the standard library, has no external dependencies, and is licensed under MIT.

NoteDiscovery is a lightweight, self-hosted knowledge-base and note-taking application developed by Gamosoft. It stores notes as plain Markdown files in folders on the user's server and provides search, navigation, graph views of connected notes, an outline panel, favorites, themes, plugins, LaTeX/MathJax, HTML export, printing, responsive desktop, tablet, and mobile interfaces, and an in-app drawing editor that saves sketches as PNG files alongside notes. The application serves its browser libraries locally without requiring a CDN, allowing operation on air-gapped networks. It can be deployed with optional password authentication and Docker, and includes a built-in Model Context Protocol (MCP) server for compatible assistants such as Claude and Cursor. Through the MCP integration, assistants can search, create, edit, move, tag, and append to notes and explore connections between them.

git-knife is a desktop GUI for editing Git commit metadata, including messages, author and committer names and email addresses, and author and committer dates. It can open a repository and edit a local branch by its ref without checking it out, leaving the working tree untouched. The application shells out to the system Git CLI and rebuilds commits with `git commit-tree`, reusing each commit's original tree so the file contents are not changed. It supports literal or regular-expression find-and-replace across metadata fields, previews changes before applying them, preserves merge parents when rebuilding the commit graph, and creates an automatic backup ref for restoration. It also warns about rewriting pushed history and flags signed commits whose signatures would be affected. The repository describes reorder, squash, and drop operations as not yet implemented. Development requires Git 2.x, Node.js with pnpm, and Rust; Tauri build workflows target macOS, Linux, and Windows.
