| Spec score · Secure Notes Apps | 8.1 (#9) | 7.7 (#19) |
| AI integrations | Its built-in AI Chat plugin supports OpenAI-compatible services including Ollama, LM Studio, OpenAI, DeepInfra, Groq, Together, and OpenRouter. | Users can connect ChatGPT or Claude subscriptions, or provide API keys for OpenAI, Anthropic, and OpenRouter. |
| Editor | The live Markdown editor includes slash commands, tables, code blocks, LaTeX math, and Mermaid diagrams. | The Markdown editor includes wiki-links, foldable headings, slash commands, and more than 20 extensions. |
| Encryption | The encrypted database uses AES-256 with a passphrase and derives its key with Argon2id; Binderus says a lost passphrase cannot be recovered. | Locked notes use AES-256-GCM with a key derived from the lock password using PBKDF2; the key stays in the browser. |
| Purpose | Binderus is a local-first note-taking app with WYSIWYG editing of plain Markdown files. | OpenVLT is a self-hosted notes app that stores notes as plain Markdown files on your server. |
| Support | The docs direct users to the FAQ, Discord, or GitHub issues for help. | The documentation directs users to email support or open an issue on GitHub. |
| Sync limitation | Vaults must be located under the operating system’s Documents directory for Binderus to read and write them. | Sync is document-level and asynchronous, and simultaneous edits can produce a conflict file for the user to review. |
