Voiact
Voiact turns routine Trello upkeep into a voice or chat command instead of clicking through boards, and it reaches further than the board itself with mail and calendar integration in the same chat. The catch is the request-based free tier disappears fast for a real team, and it only reaches Trello, not other project trackers.
Pros
- Works over voice, chat, and as a listed Trello Power-Up rather than a third-party bolt-on
- Reads and sends mail and manages calendar events from the same chat interface, not just Trello cards
- Handles bulk card operations, not just single-card edits
Cons
- Locked to Trello — no support for other board tools
- Free tier's 20-request cap is used up quickly by a real team
- No published API for wiring it into other systems
