Synapse AI

Your AI second brain inside Obsidian — chat with your notes, bring your own key, keep your data private.

Report a bug · Request a feature · 🇬🇧 English · 🇷🇺 Русский

Synapse AI turns your vault into a knowledge base you can talk to. Ask questions, pull notes in as context, and save the best answers back as permanent notes — powered by the model you choose (Gemini, OpenRouter, or any OpenAI‑compatible API, including local Ollama / LM Studio) with your own key.

⚠️ Beta. Core chat works and is in daily use. Semantic search (embeddings), agents and a local privacy layer are on the roadmap.

Features

• 💬 Chat in a side panel — streaming responses, stop mid‑stream, regenerate, edit your messages.
• 🔌 Bring your own model — Gemini, OpenRouter, or any OpenAI‑compatible endpoint (custom baseURL, incl. local Ollama / LM Studio). Add several and switch on the fly.
• 📎 Vault‑aware context — pull notes into the prompt via [[wikilinks]], the active note (toggle), or automatic keyword search.
• 💾 Save reply as a note — turn any answer (or a selected fragment) into a permanent, linkable note with frontmatter. Right‑click a message for the full menu.
• 🗂 Chat autosave — conversations saved as plain .md in your vault (configurable, optional).
• 🌐 Proxy support — route requests through your own proxy/VPS (for geo‑blocked regions)
• 🌍 Localization — English & Russian UI.
• 🔒 You stay in control — your notes and key go only to the AI provider you pick (or your own proxy). No middle‑man server, no analytics.
