How to Convert a Gravity Forms Survey to an AI Interview (2026)
A field-by-field guide to migrating a Gravity Forms survey into a Koji AI-moderated interview: map every core and Survey Add-On field to one of Koji's 6 structured question types, add AI follow-up probing, and theme responses automatically.
Converting a Gravity Forms survey into a Koji AI interview takes about 20 minutes: you map each Gravity Forms field to one of Koji’s six structured question types, move contact fields to the intake form, turn on AI follow-up probing, and publish a single interview link. You keep every number your Gravity Forms survey collected — Likert averages, star ratings, choice distributions — while adding something a static WordPress form can never do: an AI moderator that asks “why?” in the respondent’s own words and themes every open answer automatically.
Why convert a Gravity Forms survey to an AI interview?
Gravity Forms is an excellent form builder for WordPress. But a form is a one-way instrument: it records whatever the respondent types into the box and stops there. If someone rates your onboarding a 3 out of 5, the form saves “3” and moves on. You never learn what the 3 actually means, which is exactly the insight you needed.
An AI interview closes that gap. With a platform like Koji, every question you migrate can carry up to three AI-generated follow-ups, so a low rating triggers an immediate, conversational “What made it a 3 rather than a 5?” — and the answer is captured, transcribed, and thematically coded with no moderator in the room. Koji’s AI handles this automatically across hundreds of respondents at once, which is why teams describe the switch as replacing days of manual verbatim reading with a report that is ready the moment interviews close.
Three differences matter most when you move off a static Gravity Forms survey:
- AI follow-up probing turns every open question into a real conversation instead of a one-line fragment.
- Voice or text — respondents answer by speaking or typing, on any device, from the same shareable link.
- Real-time themed analysis clusters open answers into named themes with supporting quotes, so you read insights instead of scrolling raw entries.
Map every Gravity Forms field to one of Koji’s 6 question types
Koji interviews are built from six structured question types: open_ended, scale, single_choice, multiple_choice, ranking, and yes_no. Nearly every Gravity Forms field — core fields plus the Survey Add-On field types (Likert Scale, Rank, and Rating, available on the Elite or Nonprofit license) — maps cleanly onto one of them.
| Gravity Forms field | Koji question type | Notes |
|---|---|---|
| Single Line Text, Paragraph Text | open_ended | The AI probes up to 3 times for the “why” behind the answer. |
| Drop Down, Radio Buttons | single_choice | Reuse your exact option labels. |
| Checkboxes, Multi Select | multiple_choice | Pick one or more. |
| Number (used as a rating) | scale | Set the range, e.g. 1–5 or 0–10. |
| Survey Add-On: Likert Scale | scale | One scale question per statement — see below. |
| Survey Add-On: Rating (stars) | scale | Map a 5-star field to a 1–5 scale. |
| Survey Add-On: Rank | ranking | Respondents order items by preference. |
| Two-option yes/no radio | yes_no | Renders as a clean binary with a follow-up. |
| Name, Email, Phone, Address, Website | intake form | Identity fields move to the pre-interview intake. |
| File Upload, Section Break, Page Break, HTML | dropped / structure | Sections become interview sections; layout fields aren’t needed. |
A Gravity Forms Likert matrix (several statements sharing one scale) becomes one Koji scale question per row. That looks like more questions, but each becomes a conversation the AI can probe — so instead of a grid of numbers you get a rated answer and the reason behind it.
Move identity fields to the intake form
Every Name, Email, Phone, and Address field you used in Gravity Forms to identify a respondent moves out of the question flow and into Koji’s intake form, which runs before the interview starts. This keeps the conversation focused on insight rather than admin, and still links each transcript to a known participant for segmentation later.
Add what Gravity Forms can’t
Once your questions are mapped, switch on the capabilities a WordPress form simply doesn’t have:
- AI follow-up depth. Set 0 follow-ups for a quick quantitative item, or up to 3 for questions where the reasoning matters most.
- Scale anchors. On any scale question, enable the anchor follow-up so the AI automatically asks “You said 4 — what would make it a 5?” the moment a respondent rates.
- Voice or text mode. Voice interviews cost 3 credits and text interviews 1 credit; both come from the same link.
- Automatic themes. As responses arrive, Koji codes open answers into themes with representative quotes and charts every scale and choice question — no export, no spreadsheet.
Gravity Forms to Koji in 5 steps
- List your questions. Open your Gravity Forms form and note each field’s type, label, and options.
- Recreate them in Koji. Map each field using the table above; keep wording identical so historical trends stay comparable.
- Set probing depth. Choose 0–3 follow-ups per question and turn on anchors for key scales.
- Move identity fields to intake and pick voice, text, or respondent’s choice.
- Publish and share the link anywhere you shared the Gravity Forms form — email, your WordPress site, or a QR code. Insights populate in real time.
Pricing: Gravity Forms vs Koji
Gravity Forms is a WordPress plugin licensed annually — roughly $59/year (Basic, one site), $159/year (Pro), and $259/year (Elite, which unlocks the Survey Add-On and its Likert, Rank, and Rating fields). Because it is self-hosted, there is no per-response fee, but there is also no analysis: you pay separately, in staff hours, to read and code every open answer.
Koji folds collection and analysis into one step. The Insights plan is €29/month (29 credits) and the Interviews plan is €79/month (79 credits), with annual billing giving two months free. Text interviews cost 1 credit, voice 3, and a report refresh 5 — and a quality gate means only conversations scoring 3 or higher consume a credit, so blank, joke, or bot responses are free. New accounts get 10 one-time credits to test a full migration before paying.
When to keep Gravity Forms
Be honest about fit. Keep Gravity Forms for transactional jobs it does brilliantly: payment and order forms, event registrations, file-upload submissions, and tightly WordPress-embedded lead capture. Reach for a Koji AI interview whenever the goal is understanding — onboarding feedback, churn diagnosis, concept tests, NPS follow-up — where the reason behind each answer is the whole point. Many teams run both: Gravity Forms for the transaction, Koji for the conversation.
