The short version
- Only CouchDB has a free tier, so it costs nothing to try first.
- Each has a real cost: CouchDB append-only storage model may have performance implications for certain workloads with high update rates; Notion AI full AI access including agents and meeting notes requires the Business plan at $20 per member per month, double the $10 Plus plan
- They diverge on capability: CouchDB covers Multi-master Replication, Notion AI covers Writing assistance.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CouchDB
- Append-only storage model may have performance implications for certain workloads with high update rates
- Requires network synchronisation for cluster data consistency; can introduce latency in multi-master scenarios
- No explicit support for complex joins; MapReduce queries may be inefficient compared to relational databases
Notion AI
- Full AI access including agents and meeting notes requires the Business plan at $20 per member per month, double the $10 Plus plan
- The Free and Plus plans offer trial AI capabilities rather than the full feature set
- AI is not sold separately from the workspace seat, so every member must be upgraded to reach it
- Zero data retention with LLM providers is Enterprise only, which is custom priced
