Commentography από Fro K

Cache, search, and analyse comments on WordPress, Discourse, and Substack. Demographics, sentiment, networks, timezones, sock puppets, and 40+ analytics sections — all stored locally, nothing leaves your browser.

Commentography turns comment sections into a research tool. It caches every comment from any WordPress, Discourse, or Substack site you visit, then lets you search and analyse them — all locally in your browser, with no data ever leaving your device.

Search
Find any comment instantly across your entire cache. Filter by date range, username, or keyword. Exact phrase matching with quotes. Search live from the site or across everything you have cached. Results open in a dedicated tab for sharing or printing.

Analytics — 40+ sections across 9 groups

Users — per-user profiles with full comment history, posting rhythm heatmaps, and writing style analysis. User rankings by activity score. Side-by-side comparison of multiple users over time.

Activity — comments per day, week, month, or year. Velocity and site health trends. User activity spans — who has been around the longest.

Conversations — reply networks, hot comments, Q&A threads, monologue detection (articles dominated by a single voice), and conversation diversity.

Content — longest and shortest comments, reading level (Flesch-Kincaid), comment tone and sentiment, emotional arc per article, comment gap timing, most-linked domains, and contact info detection.

Language — word cloud, vocabulary drift over time, word search, and term trends as a line chart.

Demographics — estimated user timezones (from posting patterns), language detection, estimated generation, estimated location, and estimated gender — all inferred from writing, not collected.

Moderation — sock puppet detection (12-signal similarity scoring), deleted user and deleted comment tracking.

Cross-site — find users who comment on multiple sites you have cached.

Database
Full control over your local cache. Import by date range or all at once. Export as a portable ZIP or CSV. Article gap scan finds exactly which articles have missing comments and fetches only those. Full rescan with manual start page for resuming after a network error.

Privacy
Everything is stored locally using your browser's built-in storage. The extension never phones home, sends data to any server, or tracks anything. It fetches data from the sites you visit using your existing login session — the same way your browser does.

Platforms
Works on any WordPress site (including self-hosted), any Discourse forum, and any Substack publication. Add a site in one click by navigating to it and pressing +.
