Capture, organize and reuse your AI conversations — privately.
The only way to prove we're not mining your data: show you the code.
NODUS is a browser extension that captures and organizes your AI conversations across ChatGPT, Claude, Gemini, Perplexity, Copilot, Grok and DeepSeek.
Your captured content stays on your device. No accounts required. Anonymous usage telemetry is collected to improve the product — no conversation content, disableable in settings.
- AI conversations disappear when sessions end
- Valuable insights get lost across 7 different platforms
- No way to organize, search or reuse what you've captured
- Existing tools are closed-source black boxes
- One-click capture — save responses with a single button
- Quick save — zero-friction capture without modals
- Dashboard — organized cards, tags, notes and search
- Chains — link multiple captures into structured workflows
- Projects — group related ideas into projects
- Inject — send saved content back into any AI conversation
- Local storage — your captured content never leaves your device

AI Platform → NODUS Extension → Your Browser Storage (local only)
- All data stored in
chrome.storage.localand IndexedDB - No conversation content is sent to external servers
- Telemetry is anonymous and auditable
- Export your data anytime — it's yours
Telemetry is on by default (opt-out) and can be disabled at any time in Settings.
When enabled, it collects anonymous aggregated usage statistics (counts, not content). No PII. No conversation text. No platform data.
You can read the exact implementation in telemetry/.

Why Open Core? We capture your AI conversations. The only credible way to prove we handle them correctly is to make the code auditable. No trust required — verify it yourself.
Note: PRO and core logic are currently co-located in the same files. A clean architectural split into *.core.js / *.pro.js is planned post-launch.
