Architecture

Protection that starts
where work happens.

SecureIntent protects credentials and sensitive data at the point of paste. Detection runs on your device, before a browser-based AI tool receives the prompt.

Three local stages before an AI prompt leaves the browser.

Your secrets.
Your side of the screen.

Trust through transparency. How we protect you without ever seeing your code. A security tool should earn your trust—here’s what happens before you send.

  1. 1. Intercept Event

    User triggers a copy and paste inside the browser.

  2. Volatile memory

    2. Local AI Evaluation

    Regex and entropy scoring run in RAM. No disk writes.

  3. 3. Guided Sanitisation

    Choose to block the paste or anonymise detected keys before sending.

Detection and anonymisation happen on your device.

Detection happens on your device.

SecureIntent intercepts the paste event and evaluates the text using regex and entropy scoring in local RAM. Your raw pasted text isn’t sent to a server to be scanned.

Your pasted content isn’t stored for detection.

Detection runs in volatile memory, with no disk writes. Choose to block the paste or anonymise detected values before sending. Anonymous fingerprints and detection metadata may be sent for aggregate reporting, never your raw text.

You can inspect the source.

The extension code is publicly available. See how interception, local evaluation and guided sanitisation work, and how your information is handled.

Designed to be checked

Security should not be
a black box.

The original architecture commitments, made easier to scan and assess.

100% auditable code

The extension codebase is publicly verifiable and auditable.

Dehydrate & Rehydrate

Tokens can be salted and anonymised on the way out, then rehydrated in local RAM when the model replies.

Built for flow state

SecureIntent runs in the background and guides a sensitive moment rather than arbitrarily blocking a prompt.

Advanced entropy

Entropy scoring complements regex detection to identify undocumented and high-entropy keys.

Reproducible builds

A public GitHub pipeline is designed to make the Web Store binary match the published source.

Minimal permissions

The extension requires storage and activeTab, with no global clipboard read or background tracking.

Coverage

High-accuracy detection.
Where you work.

Browser coverage is available now. Desktop and agent layers extend the same local protection model.

Available now

Browser platforms

Chrome, Edge, Brave, Opera and Firefox support browser-based paste protection across AI tools.

Desktop beta

Desktop architecture

A lightweight agent observes the clipboard and desktop AI workflow, then evaluates content locally in RAM before it leaves the machine.

In development

MCP and agent security

Discover MCP connections, distinguish approved servers from unapproved ones and apply policy as agents connect to tools.
