PDF annotation tool for research papers

Helps researchers annotate academic PDFs with persistent highlights, categories, and codes, making it easier to organize and revisit important sections of papers.

User opens extension popup -> uploads/selects a PDF file -> highlights text and adds categories/codes -> views annotations in sidebar -> can export all annotations to Excel

Target users: Researchers / Academics / Students reading academic papers

The main logic is in a single minified webpack bundle (extensionPage.js ~1.7MB), making detailed feature-by-feature code tracing difficult. However, key signals (no auth, no payments, local processing) are clear from manifest, store description, and absence of relevant patterns.

Monetization

No paid features detected

No payment platforms, subscription flows, upgrade prompts, or billing APIs were found in the code. The extension is described as an 'ongoing school project' with no mention of paid tiers. Keywords like 'license' and 'pro' found in static scan are from MIT/Apache license headers and React/MUI library code, not extension monetization.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension processes PDFs locally in the browser. No login UI, auth tokens, session management, or remote API calls requiring authentication were found. The manifest has no permissions for identity or remote services. The description states 'Create persistent highlights on uploaded pdf files (only in extension)', confirming local-only processing.
