| Feature | Description |
| Question text | Customized question text for each question can be displayed at the top of the entry form. |
| Help text | A help shortcut (F2 on desktop or the ? button on mobile) can bring up customized help information for each field. |
| Multiple languages | The CAPI entry application can be developed with question and help text in several languages; the interviewer can switch among languages as needed. |
| Response boxes | During entry, a response list of valid values for each question can be optionally displayed; these can make the interview go more smoothly. |
| Notes | Interviewers can enter field notes when needed. |
| Support for partial save | CAPI applications can be developed so that they support partial save. This lets the interviewer save an incomplete case, then return later to complete it. |
| Customized branching | The entry application can determine on the fly which forms or questions to present based on the user's previous responses. This is accomplished through program logic. |
| Immediate editing | Responses can be edited, and errors or possible mistakes signaled to the interviewer. This can help improve data quality. |
