For solo lawyers, paralegals, accountants, HR, healthcare admin, and consultants bound by confidentiality.
Every AI document tool has the same first step: upload your file. For most people that's fine. For anyone handling privileged, regulated, or client-confidential documents, it's the step that makes the whole category unusable. Your bar association, your engagement letter, your HIPAA training, or your firm's policy says the same thing: client data does not go into third-party cloud AI.
The usual answers are bad. Enterprise legal AI starts around $99 per user per month and is built for contract teams at firms, not a solo practitioner. "Privacy" browser tools that scrub text before you paste it into ChatGPT only hide the obvious patterns — and you're still uploading the document. And doing it all manually is where you are now.
Modern browsers can parse a PDF, run rule-based analysis, and even run a small AI model — entirely on your machine. No server round-trip, which means no data-processing agreement to negotiate, no vendor retention policy to audit, and no "we promise we delete it" to take on faith. Privacy stops being a contractual claim and becomes a property of the software: nothing is transmitted, so there is nothing to leak, subpoena, or breach.
Deterministic, rule-based analysis does the trust-critical work — it can't hallucinate a clause that isn't there. On supported hardware, an on-device AI layer adds plain-English explanations and ask-the-document Q&A, with every answer linked back to its source passage.
On-device analysis is triage, not counsel. It won't out-reason a $2,000/month legal AI trained on case law, and it doesn't try to. It reads, extracts, flags, and redacts so that you — the professional — review faster and miss less. If you need portfolio-scale contract analytics with playbook negotiation support and your firm has cleared a cloud vendor, an enterprise tool is the better choice.
We're building a browser extension for exactly this problem: drop a PDF or DOCX and get risk flags, clause extraction, PII redaction, and summaries — 100% on your device. No account, no server, no subscription. One-time license. By hakeemify, maker of Roost.
We'll email you once, at launch. Nothing else.
Yes, in a stronger sense than cloud tools: the document is parsed and analyzed locally in your browser and never transmitted. There is no server that receives it, so privacy doesn't depend on a vendor's retention policy — it's a property of the architecture.
That's the intended use case. Because nothing is uploaded, using it doesn't share client data with a third party. As always, confirm against your own firm's or regulator's policy — you remain the decision-maker.
No. It's a triage and extraction assistant: it flags risks, extracts terms, redacts sensitive data, and summarizes. Professional judgment stays with you. It does not give legal advice.
PDF, DOCX, and plain text, plus the web page or selected text you're viewing. Files are parsed locally in the browser.
The core analysis (risk flags, extraction, redaction, summaries) runs in any modern browser with no account and no AI hardware. The optional AI assist layer uses your browser's built-in on-device model where available.
