Can I export my conversations to Word or PDF?

Yes. Export any capture as DOCX (Word) or HTML (printable as PDF). With Chains, chain multiple captures together and export everything as a structured document.

If I uninstall the extension, do I lose everything?

Before uninstalling, use the full export function to back up all your captures. Data lives in browser local storage — uninstalling clears that storage.

Real privacy

Your data stays with you.

No account. No server. No company with access to your conversations.

Everything on your device

Your captures are saved directly on your computer — not on any server, ours or third-party.

No account, no tracking

We don't ask for email, don't build a profile, don't monitor what you save. It's an extension, not a service.

You control everything

Export, delete or move your data whenever you want. Nothing gets locked in — it's your history, your rules.

Open source and verifiable

NODUS is open source. No need to take our word for it — the code is on GitHub for anyone to check.

🔗 EXCLUSIVE FEATURE

Chains: your thinking
never starts from zero again

A chain is an ordered trail of connected ideas — from any platform, any conversation, in any order you want. You build the reasoning gradually, over days. NODUS keeps everything linked.

📎

Connect ideas from different platforms

One response from ChatGPT, another from Claude, another from Gemini — all in the same chain.

🗓️

Build over time

Add new nodes whenever you want. A chain can grow over days, weeks, entire projects.

💉

Inject back into any AI

Select a chain and send the full context to continue the conversation where you left off.

📤

Export whenever you want

Export the chain as structured text to document, share or archive.

#1 Claude Mar 28

Pros and cons: JWT vs session-based auth

JWTs are stateless and scale horizontally, but revocation is hard without a blocklist. Sessions require server-side state but allow immediate invalidation.

#2 ChatGPT Mar 29

Unit tests for the auth middleware

Use Jest with custom matchers for auth errors. Mock the token validator at the module boundary and test each middleware in isolation.

#3 Gemini Mar 30

Edge cases to test before going to production

Expired token during a long request, forced revocation on password change, multiple active sessions and token reuse attempts after logout.
