Most project-tool comparison articles pick a winner and then work backward to make the case. This is not that kind of article. Trello is one of the most well-designed tools in project management — simple by design, deeply familiar, with a Power-Up ecosystem that took a decade to build. We studied it carefully when we designed Comuna. Some things we matched, some things we replaced, and some things Trello still does better.
Here is the actual side-by-side.
What Trello does genuinely well
Ubiquity is a feature. Trello's Kanban model is the one the internet taught an entire generation of PMs and developers. The learning curve is almost zero — drag a card, move a list, add a label. Your new hire has used it before. That familiarity is worth something real.
The Power-Up ecosystem is hundreds of integrations: GitHub, Google Drive, Slack, Salesforce, Jira, Figma, and dozens of calendar and automation connectors. If your workflow is built around a specific tool, there's probably a Power-Up for it.
Butler (Trello's automation engine) lets you write rule-based automations without code: "when a card is moved to Done, send an email to the reporter". It's not flexible enough for complex workflows, but for simple recurring steps it works well.
And Trello sits inside the Atlassian ecosystem. If your company already runs Jira for engineering, Confluence for documentation, and Jira Service Management for support, adding Trello costs almost nothing to integrate — SSO, admin, billing, and user provisioning all share the same stack.
What changes when the AI is a member of the board, not a feature
This is where the comparison shifts.
Trello has added AI-powered features — card summarization, drafted descriptions, smart suggestions. They're useful. But the underlying model is the same as most tools: AI as a sidebar. You write the cards; the AI reads them back to you in a different format.
In Comuna, Claude or ChatGPT is a board member. It has its own account, its own avatar in the activity feed, its own list of assigned cards. You connect it once (OAuth, no API keys) and it can create cards, move them through columns, write notes, flag blockers, and close tasks when done.
The key architectural decision is attribution. Every action the AI takes carries its badge: "Claude created this card on Tuesday." "ChatGPT moved this to In Progress." If you ever need to audit what happened on a project, you can tell the human decisions from the AI decisions at a glance. No anonymous edits. This sounds obvious, but it isn't — the dominant pattern today is to attribute AI actions to the human who triggered the prompt, which means the audit trail disappears.
The other key decision is escalation. When the AI hits something it's not confident about — "should I close this card, or wait for the client to respond?" — it doesn't guess. It opens a small approval request. You see it, decide, and the AI reads your decision the next time it runs. You stay in control; the AI handles the execution.
The cost picture
Trello's free tier covers basic Kanban for small teams. When you need timeline views, advanced automations, per-user permissions, or admin controls, you move to paid plans — per seat, per month.
Comuna is free forever, with no feature gating. Unlimited projects, unlimited team members, every view (Kanban, Table, Calendar, Gantt, Diagrams, Canvas), built-in chat, notes, wiki pages, the AI coworker — all included, no credit card.
The AI isn't a paid add-on either. You bring your own Claude or ChatGPT subscription — the one you're probably already paying for. We don't proxy tokens or add a margin. Your AI subscription already covers it.
What you'd be giving up
We think it's worth being direct about this.
The Power-Up ecosystem. Trello's library of integrations is a decade old and very deep. If your workflow depends on a specific third-party Power-Up that hasn't been rebuilt anywhere else, switching tools means rebuilding that connection. For most teams, the integrations that matter (GitHub, Slack, Google Drive) are available natively in modern tools — but check before you migrate.
The Atlassian fit. If your company runs Jira and Confluence and Jira Service Management, the administrative overhead of introducing another tool is real. SSO, provisioning, billing — it's not just the tool, it's the system around it. For pure-Atlassian shops, this is a genuine reason to stay.
Institutional muscle memory. If a twelve-person team has four years of Trello habit, that's real. A migration to any tool costs time, even when the concepts are identical (lists → columns, cards → cards, labels → labels). Factor that in honestly.
Migrating from Trello
The conceptual mapping is one-to-one. Trello's board is a project. Lists are columns. Cards are cards. Labels are labels. Attachments and checklists work the same way.
The practical move: export your Trello board as JSON (Trello → Show menu → More → Print and export), then create the matching structure in Comuna manually or with the AI coworker's help. Start with one board, run it for two weeks, then migrate the rest. Most teams find the transition takes a day of setup and a week of habit-changing.
Comuna is free forever — no credit card, bring your own AI. Spin up a workspace and try it.
