SiderMem

Capture, organize and resurface your best AI moments. Works with ChatGPT, Claude, Gemini & DeepSeek. A great cloud notepad too.

Every great AI session starts with the right context. SiderMem is the memory layer that captures, organizes, and resurfaces what matters — so your next conversation picks up exactly where the last one left off. Works just as well as a lightweight cloud notepad — capture anything worth keeping, access it from any device, and find it instantly. ✦ CAPTURE IN ONE CLICK Save anything from ChatGPT, Claude, Gemini, and DeepSeek without leaving the page. SiderMem lives in your side panel — always at hand, never in the way. Import from .txt, .md, and .pdf files too. ✦ ORGANIZE WITH NAMESPACES Group memories into namespaces — projects, clients, topics, anything you like. Star your most important entries for instant access. Link related memories together to build a connected knowledge base, not just a list. ✦ ASK YOUR MEMORIES Chat with your knowledge base in plain language. Pick a namespace, ask anything — SiderMem surfaces the most relevant memories, explains its reasoning, and answers using only your own notes. No hallucinations. ✦ VISUALIZE YOUR KNOWLEDGE Switch to Graph view for an Obsidian-style force-directed map of your memories. See how ideas connect, explore by namespace, and click any node to open the full memory. ✦ AI-POWERED TOOLS → AI Summary — compress a long conversation 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 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 vault. Query your memories from any terminal or AI agent 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 memories 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 SiderMem is for people who want to get more out of AI — and for anyone who's tired of losing good ideas to a browser tab they'll never find again. ───────────────────────────────────────── Privacy Policy: https://sidermem.com/privacy.html Terms of Service: https://sidermem.com/terms.html
