Reagent provides the AI model through its own service, and you pay for the model’s work with credits.

Plans

See pricing for current prices and what each plan includes. Reagent uses your plan credits first:
  • Plan credits come with your plan. Trial credits never reset. Paid-plan credits reset each billing period, and unused ones don’t carry over.
  • Add-on credits are credits you buy on a paid plan. They’re used only after plan credits run out, and they never expire.
Manage billing on the website dashboard. Polar handles subscriptions and payments. After you pay, new credits usually appear in the app within a few minutes (up to 5). If they don’t, click Refresh in Settings > Subscription.

What Uses Credits

Every reply uses credits. Some tasks cost extra: A reply costs more the more the model reads and writes:
  • Long chats. Every new message resends the earlier conversation, or a summary of it.
  • Attachments. They add to what the model reads.
  • Big tasks. Every step of a many-step request uses the model.
To save credits, start a new chat when you switch to an unrelated task.

Stopping a Reply

Stopping a reply doesn’t refund credits. You’re charged for finished work, and the step in progress keeps running on the server and can still be charged in full.

Check Your Balance

The bottom of the sidebar shows your plan, a credit bar and remaining / total (+N). remaining includes add-on credits, total is your plan’s amount, and (+N) is how many of the remaining are add-on credits. It updates on its own.

When You Run Out of Credits

At zero credits, Reagent can’t reply. If you send a message, the reply stops right away and the chat shows a Credits Exhausted card with one button: On a paid plan, you can also wait for the next billing period. Once you have credits, resend your message.
If you run out partway through a task, Reagent stops at its next step. Changes it already made in REAPER stay in your project, so check where it stopped before you continue.

Buy Credits, Upgrade or Cancel

Buy Add-on Credits

On a paid plan, click Buy Credits on the dashboard’s Credit Balance card. In the Add credits window, enter an amount and check out. The window shows the allowed range and total price.

Upgrade Your Plan

On the dashboard, under Available Plans, click Upgrade to … on the plan you want.
  • From Free: check out. Your plan’s credits replace any trial credits you have left. Add-on credits aren’t affected.
  • From a paid plan: your plan changes right away, with no confirmation step. Polar immediately charges the prorated difference for the rest of your billing period. The plan shows Activating until the change comes through.

Switch to a Cheaper Plan or Cancel

The dashboard can’t move you to a lower plan directly. To switch to a cheaper plan or stop paying, cancel first.
  1. On the dashboard’s Credit Balance card, click Manage Subscription to open Polar’s billing portal.
  2. Cancel there. The card shows Canceled and your plan’s end date. You keep your plan and its credits until then. After that, unused plan credits are removed, add-on credits stay, and the app shows Free.
  3. Optional: after your plan ends, click Upgrade to … on the cheaper plan. The button says Upgrade even though the plan costs less.
