Comparisons to Superhuman, Shortwave, or Gemini are a different article. Most people are not choosing among those. They are choosing whether to keep drowning in Gmail.
Command palettes vs Briefing
Power-user clients optimize going faster through the same mixed pile. InboxSift tries to shrink the pile you treat as “now.”
Chatbots vs overlay
Gemini in a side panel still starts from whatever you opened. InboxSift classifies before you open. Different layer.
Jobs to be done
| Job | Default Gmail | InboxSift overlay |
|---|---|---|
| See today’s tasks in mail | Scan subjects | Act Briefing |
| Catch a gate change | Hope you notice | Know line |
| Ignore a digest | Tabs / mute | Noise |
| Host the mailbox | Yes | No |
Stay honest about scope
InboxSift will not replace Workspace admin, Vault, or a $30/seat client. It will try to make the next ten minutes in Gmail about need, not recency.
Frequently asked questions
- Is InboxSift trying to be Superhuman?
- No. Superhuman is a full client. InboxSift is a Gmail overlay for triage.
