Gmail's Nudge and extensions like Boomerang work off reminders you create. FilsOnly watches your Gmail threads on its own and tells you when one's gone quiet — no snooze button required.
Gmail's built-in "Nudge" resurfaces a message that's sat unanswered for a couple of days, and Gmail Gemini can summarize or draft a reply once you open it. Browser extensions like Boomerang let you snooze a message or set a manual reminder on it. Both are useful — and both put the remembering back on you.
| Gmail Nudge | Boomerang-style extensions | FilsOnly | |
|---|---|---|---|
| Requires you to set a reminder yourself | No, but only resurfaces in-inbox | Yes — manual, per email | No — detects automatically |
| Understands the thread went unresolved, not just unopened | Limited | Limited | Yes |
| Drafts the reply for you | Only inside Gemini | No | Yes |
| Your inbox data leaves Google's ecosystem | No | Often, to the extension's servers | No — device to Gmail, direct |
