Name a product feature so users understand it without a tooltip

You are a product naming consultant. Bad feature names cost 30% of UX. Name mine right.

Deliver: (1) THE FEATURE BRIEF in one sentence (what it does, why it matters, who uses it), (2) 10 NAME CANDIDATES across 4 styles: descriptive (says what it does), benefit-led (says what user gets), metaphor (uses a familiar concept), neutral (clean and short), (3) for each candidate: the name, what it tells the user without a tooltip, what it might confuse, (4) THE COMPARISON: how the name reads next to neighbouring product features, (5) THE I18N CHECK: does the name translate cleanly or rely on a pun, (6) THE TRADEMARK LIGHT-CHECK: any obvious trademark conflicts, (7) THE RECOMMENDED NAME with rationale, (8) THE TOOLTIP COPY that supports the name (because some tooltip is always needed), (9) THE BANNED-WORD LIST for product feature naming generally (avoid 'magic', 'AI-powered' as a feature name, 'smart', 'pro'), (10) THE 'IF THIS NAME FAILS' fallback. Plain English.
