Research Assistant Pro – Private Paper & PDF Summarizer

Summarize papers, reports, web pages, and PDFs locally. Verify exact evidence and compare sources in encrypted projects.

Turn the paper, report, or article already open in Chrome into a brief you can verify—without uploading it to a chatbot. Research Assistant Pro is a private evidence desk for pages, selected passages, text-based PDFs, and text you explicitly paste. Start with an instant local extractive brief that preserves source wording. On a compatible Chrome desktop, use Chrome's built-in on-device model for a richer overview, distinct key points, five output languages, and grounded questions. Every supported point stays connected to source evidence you can inspect. Keep the original material open, follow an evidence label back to the exact excerpt checked, and export the finished brief when you are ready. Free single-source workflow: - Research a whole page, selected passage, text-based PDF, or pasted text - Create an instant extractive brief locally, even when Chrome's AI is unavailable - Create richer on-device AI briefs on compatible Chrome devices - Choose quick, standard, or detailed output - Ask grounded questions and inspect the exact source excerpts checked - See answer drafts progressively and stop an answer without retaining it - Use English, Spanish, German, French, or Japanese AI output - Copy the result or download a Markdown brief Optional Pro projects: - Keep passphrase-encrypted projects in this Chrome profile - Compare up to 12 sources in a literature review, market scan, or decision memo - Build an evidence matrix with source links and supporting excerpts - Export projects as Markdown, CSV, or JSON - Download and restore an encrypted full-vault backup - Activate one annual license on up to three Chrome installations Private by design: - No Needly Labs account, research upload, cloud history, analytics, tracking, advertising, or telemetry - No permanent access to every website or browsing history - Page, PDF, selection, pasted text, question, and answer content is not sent to Needly Labs, Paddle, Keygen, or the entitlement Worker - Full source text and questions are not saved by the extension - License checks occur only after an explicit license action and contain no research content Requires Chrome 138 or newer on desktop. The instant extractive brief does not need Chrome's generative model. Richer AI briefs, output languages, grounded Q&A, and synthesis require compatible hardware and Chrome's built-in model; Chrome may need an unmetered initial download. Scanned, password-protected, and image-only PDFs are not supported. AI output can be inaccurate, so verify important information against the source evidence.
