Which plan fits today
If you are still validating the workflow, anonymous and signed-in free quota already cover lightweight tasks and first-time evaluation.
Tasks like AI PDF summary use longer context and higher token cost, so a trial-plus-credits model is more sustainable.
Anonymous users get 5 runs per day, signed-in users get 10, and credits mainly cover the high-cost workloads.
Most tools stay free, while only the truly expensive file AI flows move into credits after a trial. That creates a more natural conversion path.
Purchase flow
Step 1
Users land here when they hit a high-cost tool, run out of quota, or want to prepare credits ahead of time.
Step 2
The page now offers three fixed credit packs, and the frontend purchase entry currently exposes WeChat Pay only.
Step 3
The frontend only starts the purchase. The server remains the source of truth for payment success and account crediting.
Step 4
Once the callback is confirmed, the system writes a ledger record and updates the user credit balance.
FAQ
Yes. Credits are valid for 1 year after they are added to the account, which keeps long-term balance and reconciliation risk under control.
Credits need a stable account owner and reliable order reconciliation, so anonymous purchases are intentionally blocked.
Right now that mainly means AI PDF summary and other future high-cost file AI flows. Most local and light AI tools still prioritize free quota.
