SaneBox moves your emails into smart folders. InboxBrief reads them, summarizes them, extracts the actions and turns them into an agenda.
SaneBox pioneered automatic email filtering: it files the non-urgent into folders (SaneLater, SaneNews) to declutter the inbox. Useful - but the emails are still emails, and you still have to read them. InboxBrief goes one step further: the AI reads the content, produces a prioritized daily summary, and turns whatever needs action into dated tasks and events.
| Criteria | InboxBrief | SaneBox |
|---|---|---|
| What it does to email | Reads and synthesizes: prioritized summary + extracted actions. | Files: moves messages into folders. |
| After the sorting | A 2-minute digest, tasks and agenda already filled in. | Cleaner folders… that you still have to open and read. |
| Team mailboxes | Shared spaces: summaries, assignments, shared agenda. | Built for individual inboxes. |
| Filtering maturity | Plain-language rules, learns your priorities. | Over a decade of refining the sorting algorithm. |
| Access required | Read-only: never moves or deletes anything. | Needs permission to move your emails between folders. |
Filtering reduces noise but doesn't answer the real question: "what do I have to do, and by when?". InboxBrief answers it literally: every digest lists the detected actions with their deadlines, already placed on your agenda.
