7 Best AI Assistants for Trello in 2026
Trello has had automation longer than most tools that advertise it. Butler moves cards on due dates, applies labels, and fires on board events, and it is included with your plan. Within a board, Trello mostly automates itself.
What Butler cannot do is start outside Trello. The card that should exist usually begins as a client email, a message in chat, or a sentence in a meeting. Somebody reads that and makes the card, and if nobody does, the board quietly stops reflecting the work.
We tested seven AI assistants against Trello and ranked them by how much of that gap they close.
TL;DR: Carly is the pick. It creates and moves Trello cards from your email and messages, in plain language, with no rule to write. Butler stays the right tool for anything that starts on the board.
1. Carly
Carly is an AI agent with its own real email address, connected to Trello and to your mailbox. Forward a client email and the card appears in the right list, with the context in the description and a due date that matches what was promised. Text it “what is stuck in review” and it answers from the board. Say “move the onboarding card to done and tell Claire” and both happen.
Why it wins: Butler reacts to Trello events, and Carly starts from the conversation that should have produced a card. You describe what you want in plain language instead of composing a rule, and the same agent reaches your mail, calendar, and the rest of your stack, so the card and the follow-up meeting happen together.
Pricing: Free Zapier-style workflows; AI agents from $35/month
2. Butler and Trello’s built-in AI
Trello’s own automation, included with every plan: rules on board events, scheduled commands, card buttons, and due-date behavior, plus Atlassian’s AI assistance for drafting card content and suggesting rules.
Where it stops: it is board-shaped, which is exactly right for board-shaped work and useless for the inbox. Keep it on, and pair it with something that covers the outside.
Pricing: Included with Trello. See Trello pricing
3. ChatGPT
With a connector attached, ChatGPT can read and write Trello cards, and it is good at turning a rambling thread into a card description someone can act on.
Where it stops: one board connection at a time, and it does nothing until you open the chat and ask.
Pricing: From ~$20/month
4. Claude
Claude reaches Trello through a connector and is the strongest of the chat assistants at working out what a messy thread actually commits the team to.
Where it stops: same shape as ChatGPT. It acts when you ask, and not before.
Pricing: From ~$20/month
5. Zapier
Zapier creates Trello cards from a trigger in almost any app, with AI steps to shape the card text, and it is the standard answer for syncing Trello with other systems.
Where it stops: it is plumbing you define and maintain, and it has no judgment. A Zap that makes a card from every inbound email will make a card from every inbound email. See Zapier alternatives.
Pricing: Free plan; paid from ~$19.99/month
6. Make
Make gives you a canvas for multi-step Trello scenarios with branching and data transforms, at better economics than Zapier once the scenario grows.
Where it stops: the power lives in a canvas you build and debug. See Make alternatives.
Pricing: Free plan; paid from ~$9/month
7. Trello Power-Ups with AI
A crowded shelf of third-party Power-Ups that summarize boards, draft cards, and estimate effort, installed per board.
Where it stops: each one does a slice, they are configured board by board, and none of them can see your inbox.
Pricing: Varies; many free tiers

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
