“-- Problem here is often times the sync from one to the other will overwrite the keyword and you’ll need to have some logic in to determine, hey how long ago was the sync timestamp and if it was less than 1 minute don’t sync - yet then that will miss syncing the second change if someone makes two changes to a calendar event 30 seconds apart.”

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Power users syncing Google Calendar and Outlook experience real data loss from sync conflicts. No search volume, but the pain signal (overwriting keywords, sync timestamp conflicts) is specific and costly to users.
Competition & the opening
Crowded (7/10): Zapier, Make, built-in Outlook-Google sync, and calendar management tools exist. Gap is deduplication logic that preserves data and resolves conflicts intelligently without data loss.
What's hard to build
Building robust bidirectional sync is hard: detecting true duplicates vs. legitimate overlaps, handling time zone edge cases, managing API rate limits on both platforms, and testing against calendar rule variations. Feasibility 5/10 reflects the complexity of maintaining consistency across two major systems.
Why now
Multi-calendar workflows (Google/Outlook/Slack) are now standard but sync logic remains dumb and destructive.
How you'd monetize
$19/mo SaaS or usage-based per sync event
