Kept is a self-hosted notes app modeled after Google Keep. It supports text notes, checklists, images, drawings, links, attachments, labels, colors, pinned notes, search and filters, reminders, offline editing with synchronization, real-time collaboration, and Google Keep Takeout import. It includes local accounts, optional two-factor authentication, user management, database backups and restore, and native iOS and Android apps that connect to a Kept server. The web application uses an Angular frontend, a Node/Express backend, and SQLite storage, and can be deployed with Docker Compose or hosted through Railway.

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.

Keel is a local-first native macOS coding workspace that runs coding agents through a Rust/GPUI application. It combines sessions, a composer, transcripts, a terminal, change inspection, settings, Git history, crash recovery, and an agent graph showing active agents, subagents, and files as shared context; agents can be steered or stopped from the graph. It connects Claude Code, Codex, Cursor, Grok, Hermes, and pi through the Agent Client Protocol, and also includes an embedded DeepSeek agent loop with host-enforced tool focus. For unpinned tasks, a local Laya selector running through Core ML or an optional hosted Jev selector chooses among host-prepared routes or abstains. Keel validates each choice before applying it, falls back to the ordinary route when a choice is rejected, stale, or expired, and records candidates, validation, fallback, and observed outcome in bounded decision receipts. Decision receipts can be exported as JSONL and summarized with CLI reports. Keel also provides headless and daemon modes, while each coding provider retains its own authentication, model configuration, and tool loop. The repository supports Apple Silicon and macOS 15 or later for the packaged Laya model. It can be built from source, but the repository does not currently publish downloadable app releases; packaged builds are ad hoc signed development builds. Automatic training, public installer distribution, cloud sync, and native Codex realtime voice are not implemented or included in this build.

WeKnora is an open-source, LLM-powered knowledge platform from Tencent for turning documents into queryable knowledge bases, retrieval-augmented Q&A, autonomous reasoning workflows, and self-maintaining Markdown wikis. It supports RAG-based quick Q&A and a ReAct agent that orchestrates retrieval, MCP tools, sandbox skills, and web search for multi-step tasks. Its Wiki Mode distills source documents into structured, interlinked Markdown pages with an interactive knowledge graph, manual editing, revision history, line-level diffs, and rollback. The platform ingests formats including PDF, Word, Markdown, HTML, images, spreadsheets, presentations, and XMind, and can synchronize sources such as Feishu, GitLab, Tencent IMA, Notion, Yuque, and RSS. Its modular pipeline supports interchangeable parsers, LLMs, embedding providers, vector databases, and storage backends, with dense, sparse, hybrid, parent-child, and graph-based retrieval strategies. WeKnora provides a web interface, REST API, command-line client, MCP server, website embed widget, and integrations with messaging channels. It can be deployed locally, with Docker, or on Kubernetes, including private and offline deployments. The repository states that it is licensed under the MIT License and supports workspace RBAC, scoped API keys, audit logs, and Langfuse-based observability.
