Every plan works at the same quality. What changes between plans is how much work you can do each month - the amount of reading and writing Plank does for you. Think of it like a data plan: Starter is for light, occasional use; Plus covers daily work across several processes; Pro handles heavy, continuous usage. You can always upgrade if you outgrow your plan.

Everything the AI processes: reading your files and context, searching the web, and producing output (reports, documents, dashboards, responses). A complex spreadsheet analysis uses more than a quick question. Plank tracks this transparently so you can see where your usage goes.

Yes. You can upgrade or downgrade at any time. Upgrades take effect immediately; downgrades take effect at the end of your current billing period.

Plank uses a fair-use model with gentle reminders as you approach your monthly capacity. If you consistently hit the limit, upgrading to the next tier is almost always cheaper per unit of work.

Every plan starts with a 7-day free trial with full access. For companies, we also offer a paid proof-of-concept on a real business process before you commit.
