| 2. Wrap a UI | Add a simple page to record, convert and download. |
| 3. Limit free use | Give a small free quota so people can try before they pay. |
| 4. Share demos | Post short before and after demos on X and in directories. |
| 5. Ask for pay | Offer a yearly or monthly plan once people return. |
| 6. Watch churn | Track whether paid users keep using the product after week one. |
