An honest comparison
Looking at Checker Plus for Gmail? Here is where TriageBox differs.
Checker Plus is one of the most-liked Gmail extensions there is, and as a notifier it is the best thing in our own scorecard. TriageBox does a different job: it clears the inbox — scores it, summarises it, then sweeps it by the thousand with an exact count in front of you before anything moves.
TriageBox on the Chrome Web Store: v1.23.48. Checker Plus remains the stronger notifier; TriageBox is built to clear the pile.

Scores are 0–10 and they are ours — including the column we lose. The same scorecard, with every reason and eleven more products, ships inside the extension under Settings → Product comparison.
| What you need | TriageBox | Checker Plus |
|---|---|---|
| Desktop notifications — know mail arrived without a Gmail tab | 7 / 10 | 10 / 10 — the best in our table, with actions and even voice |
| Bulk clean-up — archive or delete whole senders and domains, with an exact count first | 9 / 10 | 2 / 10 — one message at a time; there is no sweep |
| Unsubscribe — per exact sender, so statements survive while marketing stops | 8 / 10 | 1 / 10 — nothing beyond what Gmail offers |
| AI triage — every unread scored 0–100, summaries with the actual figures | 9 / 10 | 1 / 10 — none of any kind |
| Spam review — read the whole folder at once, rescue false positives | 8 / 10 | 3 / 10 — can mark spam; no folder review |
| Price | Free · no subscription, AI on your own key | Free · optional donation for extras |
| On your phone | 0 / 10 — desktop Chrome only | 0 / 10 — desktop browser only |
