Put an AI agent to work inside Trello

Connect Trello in one click and delegate the busywork: an autonomous agent that files incoming requests as cards, labels and assigns them with judgment, keeps boards clean, and turns your boards into action across the rest of your stack. You set the autonomy, it does the work.

In short

Fleece AI connects to Trello through managed OAuth and lets autonomous agents create and update cards, move them across lists, apply labels, set due dates, assign members, and check off checklist items. Agents combine Trello with 3,000+ other apps — Gmail, Slack, Notion, Google Drive — so an email or a message becomes a well-formed card, and a board can keep itself clean, under the approval rules you set.

What a Fleece agent does with Trello

Trello organizes work as boards, lists, and cards. Each card carries a description, labels, checklists, a due date, members, attachments, and comments, and work moves from list to list as it progresses. The friction shows up as boards grow: cards land in the wrong list, due dates slip past unnoticed, stale cards pile up, and requests that arrive by email or Slack never make it onto the board at all. A Fleece agent sits on top of your boards, reads the actual content of cards, and acts — creating and moving cards, applying labels, assigning members, setting due dates, and ticking checklist items — according to instructions you give it in plain language.

Under the hood, the connection runs through managed OAuth — you authorize Trello once, and Fleece handles tokens, scopes, and refresh securely. The agent can create cards, update titles and descriptions, move cards between lists, add and check checklist items, apply and remove labels, set and change due dates, assign and unassign members, post comments, and read board and card activity. Event triggers let it react in real time when a card is created, moved, assigned, or when a due date approaches — no polling, no delay — and it can work alongside the power-ups your team already relies on.

What makes this different from Butler, Trello's native automation, is judgment. Butler runs rule-based commands — buttons, card, board, calendar, and due-date rules that match a fixed trigger to a fixed action. An agent reads the card's description and comments, decides what the card is actually about, writes the label, assignment, or reply a person would, and coordinates other tools to finish the job. And because Fleece agents work as a hierarchy — a lead agent delegating to specialized child agents — one Trello-facing agent can hand research, drafting, or reporting to another agent and post the result back on the card.

What the agent can do in Trello

Card intake and triage

Files incoming requests as cards in the right list, writes a clean title and description, and assigns a member — from email, Slack, or a form.

Judgment-based labeling

Reads the content of a card and applies the labels a person would, not brittle keyword rules — then routes it to the correct list.

Board hygiene

Nudges owners on stale cards, follows up on approaching and overdue due dates, and flags cards left with no member or no checklist progress.

Editorial calendar ops

Runs a content calendar board — scheduling cards, moving them through stages, and ticking checklist items as each piece of work completes.

Real-time triggers

Reacts the moment a card is created, moved between lists, assigned, or a due date nears, through event-based triggers rather than polling.

Approval gates

Anything sensitive — archiving cards, bulk moves, external-facing comments — pauses for your one-click sign-off before it happens.

Integrations

Automations teams run on Trello

These are concrete setups you can describe to a Fleece agent in plain language. Each one combines Trello with other connected apps.

1

Support and ops: card intake that sorts itself

When a request lands via Gmail or Slack, the agent creates a Trello card in the right list, writes a clean title and description, applies labels based on what the request is about, sets a due date, and assigns a member. It attaches the source email or Slack thread to the card so the context travels with the work. Nothing gets lost between the inbox and the board.

2

Board hygiene: no more stale cards

Each morning the agent scans your boards for cards that have not moved in a week, cards past their due date, and cards with no member, then nudges the owners in Slack with a direct link. It ticks off checklist items that other tools have already completed and comments on cards where a linked Google Drive document has changed, so the board reflects reality without anyone tidying it by hand.

3

Content and editorial calendar operations

On a content calendar board, the agent moves cards through Draft, Review, and Scheduled as work completes, sets due dates from the publishing plan, and creates cards for new topics pulled from a Notion database. When a card reaches Scheduled, it posts the summary and the go-live date to Slack so the whole team can see what is shipping and when.

4

Weekly board digest to the team

Every Friday the agent reads all your boards — cards completed this week, cards slipping, checklist completion, and load per member — and posts a concise digest to Slack, then files the same summary as a Notion page for the record. The status update writes itself, and the history is searchable later.

How to connect Trello to Fleece AI

1

Create your Fleece account

Sign up and start the 7-day trial. You land in a workspace where agents, flows, and integrations live together.

2

Connect Trello via managed OAuth

Pick Trello from the integrations catalog and authorize it in one click. Fleece manages tokens and scopes for you; you can revoke access at any time from Trello or from Fleece.

3

Describe the job in plain language

Create an agent and tell it what to watch and what to do — "file new #requests as cards in Intake, label them, and nudge owners on overdue cards". No flowchart building required.

4

Set autonomy and approval gates

Choose what the agent may do on its own and what waits for your sign-off. Sensitive actions like archiving or bulk moves pause for one-click approval.

5

Run it on triggers or a schedule

Let the agent react to Trello card events in real time, or schedule recurring flows — morning board hygiene, Friday digests — that run without you.

Trello works better with the rest of your stack

Trello automations get powerful when they cross app boundaries. Pair Trello with Gmail to turn incoming requests into well-formed cards, with Slack to nudge owners on stale or overdue cards, with Notion to file board digests and pull new card topics, or with Google Drive to attach and track linked documents — all through the same agent, all under the same approval rules. Fleece connects to 3,000+ apps, so the stack you already use is almost certainly covered.
