Google Gemini in Gmail: A Designer's Take on Inline AI Suggestions

AI · 5 min read

Gemini's inline suggestions appear as light cards above the composer and in a condensed action sheet for mobile, offering grammar fixes, tone adjustments, and suggested subject lines. The placement is intentional: suggestions don't hijack the cursor but remain available, reducing interruption. We analyze the cadence of suggestions and how timing affects adoption—immediate corrections are useful, while late-stage tone suggestions often feel redundant.

Safety and provenance are surfaced via subtle badges and an "AI-suggested" chip with a tooltip explaining the change. This falls short for power users who want edit diffs; our teardown proposes a compact diff-view that highlights AI changes inline without losing the natural flow of the email. We also look at how Gemini handles attachments and sensitive content, recommending clearer cues and a sandbox mode for reviewing AI content before sending.

Lastly, the UX around undo and accountability deserves attention. One-tap undo is available, but users reported uncertainty about what exactly changed. Adding granular undo and a history panel for AI edits would boost confidence. The integration is a strong step toward assistive writing in email, but smoothing provenance and edit transparency will be critical for broad acceptance.
