With over 10,800 GitHub stars earned in under two years, Blinko has emerged as the privacy-first answer to cloud-dependent note-taking tools by combining instant thought capture with AI-powered retrieval that actually understands what you wrote rather than just matching keywords. The core engine uses Retrieval-Augmented Generation to build vector embeddings of every note in your PostgreSQL database, enabling natural language queries like "what were my thoughts on the database migration last Tuesday" to surface relevant content through semantic understanding rather than exact string matching. AI integration supports both cloud providers — OpenAI, MiniMax, and compatible endpoints — and fully local inference through Ollama running models like Llama 3.2 on your own hardware, ensuring your notes never leave your network when privacy demands it. Built on Next.js with a React frontend, the web interface presents notes as cards with full Markdown support including code blocks, LaTeX, and rich formatting, with a clean input bar for capturing fleeting thoughts in seconds. The Tauri-based desktop and mobile clients extend access to macOS, Windows, Linux, and Android with native performance characteristics. Notes are stored as plain text in PostgreSQL with vector indexes that update incrementally as new content arrives, and the embedding index can be rebuilt on demand when switching between AI providers. Multiple users can share a single instance with individual accounts, and data exports to standard formats. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Standard Notes keeps your notes, files, and tags encrypted on your device before anything touches the network, meaning the server stores only ciphertext it cannot read. Cross-platform sync across desktop, mobile, and web delivers fast, conflict-free updates on unlimited devices with the same zero-knowledge guarantee that only your password can decrypt your content. The V2 server architecture condenses everything into four Docker containers consuming roughly 570MB RAM total (down from 13 containers and 1.7GB in the legacy setup), with startup under one minute. Revision history automatically preserves every version of every note, so recovering deleted text or reverting to a previous state never depends on manual backups. A nested tag system organizes thousands of notes with hierarchical categorization that goes well beyond flat folder structures, while search operates entirely on client-side decrypted content. File attachments of any type encrypt and sync alongside notes with identical end-to-end protection. Multiple editor options span plain text, Markdown with preview, and rich formatting to fit different writing workflows. Two-factor authentication via TOTP with email backup codes adds a second barrier beyond your password. An optional separate container serves the web frontend, providing browser access to your encrypted vault without depending on standardnotes.com infrastructure. With 5,500+ GitHub stars and active development, the project continues expanding editor plugins and sync improvements.

With nearly 600 GitHub stars and a feature set that rivals commercial note apps, Glass Keep is the self-hosted Google Keep alternative that wraps a full-featured notes system in a glassmorphism UI with blurred backdrops, translucent modals, and smooth transitions. The React and Vite frontend renders notes in a masonry card grid with pinning, color themes, tag chips, and drag-and-drop reordering. Text notes support Markdown with headings, bold, italic, strikethrough, blockquotes, and fenced code blocks, while checklists offer inline editing, drag-to-reorder items, and direct toggle from the grid without opening the note. A freehand drawing mode provides customizable brush sizes and colors for handwritten notes. The private AI assistant runs an optimized Llama 3.2 (1B) model entirely inside the Docker container using RAG over your own notes, answering queries like "what are my AWS commands?" without any data leaving your server. Deep search spans titles, Markdown text, tags, checklist items, and image names. Import notes from Google Keep via Takeout JSON files or export your entire vault as JSON with per-note Markdown downloads. The Express backend with better-sqlite3 requires no external database. Real-time collaboration enables shared checklists with live item toggling. Dark and light themes persist across sessions, and the PWA manifest supports installation on any device.
