Core features

Four views, one tool

Everything is accessible from a single browser tab. Switch between Comments, Search, Analytics, and Database without losing your place.

💬

Comments

Browse comments grouped by article, rendered as threaded trees. Cache-first loading means the view is instant. Click any username to see their full profile and jump to their analytics.

🔍

Search

Search across your entire cache or live from the site. Filter by date range, username, or keyword. Exact phrase matching with quotes. Results open in a shareable tab.

📊

Analytics

40+ analysis sections across 9 groups — users, activity, conversations, content, language, demographics, moderation, and cross-site comparison. All in one page.

🗄️

Database

Full control over your local cache. Import, export as ZIP or CSV, find missing comments, run a full rescan with resume support, or check live site coverage statistics.

Database

Your cache, your control

The Database view gives you full visibility into what is cached and precise tools to keep it up to date.

⬇️

Smart import

Binary search finds the first uncached page and fetches from there. Phase 1 catches newest comments. Full rescan with a manual start page lets you resume after a network failure.

🔎

Article gap scan

Fetches comment totals per article from the site API and compares against your cache. Finds exactly which articles have missing comments and can fetch only those — no full rescan needed.

📦

Export & import

Export your entire cache as a portable ZIP (including article metadata) or a flat CSV. Import a ZIP to restore a previous snapshot or migrate between browsers.

📈

Coverage stats

See total comments on the site, how many you have cached, coverage percentage, and the oldest comment date. Gaps explained when WordPress reports unapproved comments in its totals.

Privacy

Nothing leaves your browser

Commentography is built on a simple principle: the data is yours and stays with you.

Local storage only. All cached comments, analysis results, and preferences are stored in your browser's local extension storage — the same mechanism used by password managers and other privacy-focused tools. No account required. No server. No analytics on your usage.

Fetch via your session. Comments are fetched through your open browser tab, inheriting your existing login cookies. Commentography does not handle or store your credentials.

No external requests. The extension makes no requests of its own beyond fetching comments from the site you are actively visiting. It does not phone home, send telemetry, or contact any third-party service.

Free and open source. No account. No server. Everything stays on your device.
