SiderMem

Save web pages, notes, and AI chats into a personal knowledge base with cloud sync, search, graph view, and public sharing.

SiderMem is a productivity extension for people who use AI assistants every day. It lets you capture, organize, and revisit the most valuable moments from your conversations — so you always have the right context ready for your next session. ── CAPTURE WITHOUT FRICTION ── One click saves any conversation, code snippet, or text selection from ChatGPT, Claude, Gemini, and DeepSeek. SiderMem works as a side panel, so it stays out of your way until you need it. ── ORGANIZED, NOT JUST STORED ── Tag and title every memory. Search across your entire library instantly. Two AI-powered tools help you go further: • AI Summary — condenses long conversations into a focused briefing you can paste at the start of any new session • AI Reformat — restructures raw notes into clean, scannable Markdown or plain text documents ── YOUR DATA, YOUR CHOICE ── Memories are stored locally in your browser first — no account required to get started. When you're ready, enable Cloud Sync to access your library from any device. You can export everything at any time as a single JSON file or a ZIP archive of Markdown files (fully compatible with Obsidian and other note-taking apps). ── IMPORT FROM FILES ── Paste text, or import directly from .txt, .md, and .pdf files. SiderMem extracts the content client-side — nothing is uploaded without your action. ── SHARE WHAT MATTERS ── Ultra plan users can publish individual memories as clean, publicly accessible web pages — shareable with a single link. ── PRIVACY-FIRST ── • No advertising trackers or analytics • No automatic data collection — only what you explicitly save • Cloud storage powered by Supabase (US-based infrastructure) • Passwordless login — no password to leak ── PLANS ── • Free — local storage, manual capture, core features • Pro — cloud sync, AI features (monthly quota) • Ultra — expanded AI quota + public sharing SiderMem is built for people who want to get more out of their AI workflows — without losing their best ideas to a chat history they'll never scroll back to.
