Save web pages, notes, and AI chats into a personal knowledge base with cloud sync, search, graph view, and public sharing. SiderMem turns anything worth keeping on the web — an article, a code snippet, a random idea, a whole AI conversation — into a self-organizing personal knowledge base. No folders, no manual tags. Just capture, and let your LLM-Wiki build itself. Works just as well as a lightweight sticky-notes app — jot anything down, access it from any device, and find it instantly. ✦ CAPTURE ANYTHING, ONE CLICK Right-click any page, selection, or file to save it straight into SiderMem — no copy-paste, no switching tabs. Works on every website, including ChatGPT, Claude, Gemini, and DeepSeek. Import from .txt, .md, and .pdf files too. ✦ LLM-WIKI: YOUR PERSONAL KNOWLEDGE BASE, AUTO-BUILT This is the core of SiderMem. Instead of you sorting notes into folders, an LLM reads what you save, pulls out the topics and entities inside it, and merges related captures into living wiki pages automatically — the same idea behind Karpathy's llm-wiki concept, built into your browser and always up to date. Your second brain organizes itself as you feed it. ✦ ASK YOUR KNOWLEDGE BASE Chat with your LLM-Wiki in plain language. Ask anything — SiderMem searches every page in your personal knowledge base, explains its reasoning, and answers using only your own saved content. No hallucinations. ✦ VISUALIZE YOUR SECOND BRAIN Switch to Graph view for an Obsidian-style force-directed map of your LLM-Wiki. See how topics connect to each other, and click any node to open the full page. ✦ AI-POWERED TOOLS → AI Summary — compress a long capture into a crisp briefing, ready to paste into your next session → AI Reformat — transform raw notes into clean Markdown or plain text, structured for humans and AI alike ✦ BUILT FOR DEVELOPERS & VIBE CODING SiderMem ships with a companion CLI — install with npm install -g sidermem-cli and pipe shell output, git diffs, and log files directly into your knowledge base. Carry context between vibe-coding sessions across Claude Code, Codex, and other AI coding agents, or query your LLM-Wiki from any terminal with clean JSON output. ✦ YOUR DATA, YOUR WAY Local-first — no account needed to start. Enable Cloud Sync when you're ready. Export everything as JSON or Obsidian-compatible Markdown ZIP at any time. Ultra plan users can publish individual pages as public web pages, shareable with a single link. ✦ PRIVACY BY DESIGN ✓ No ad trackers or analytics ✓ Nothing uploaded without your explicit action ✓ Passwordless login — no password to leak ✓ Cloud infrastructure powered by Supabase (US-based) ✓ AI requests always routed through our backend — never sent to providers directly ✓ Your data is never used for model training Whether you're building a second brain, keeping sticky notes for everyday life, or sharing context across AI coding agents — SiderMem is the knowledge layer for anyone tired of losing good ideas to ind again. ───────────────────────────────────────── Privacy Policy: https://sidermem.com/privacy.html Terms of Service: https://sidermem.com/terms.html
