## Diaform

Diaform is built around a simple idea: a form can collect an answer, but only a conversation can uncover the reason behind it. Its AI agents conduct customer interviews over voice or text, deciding their next question based on what the respondent just said instead of following a fixed script. Respondents get a single link — no signup, no app install — and can speak out loud or type in whichever of the 32 supported languages they are most comfortable with.

The natural voice agents start speaking immediately, use human pacing, emphasis, and pauses, and never stall mid-conversation, which keeps completion rates high and produces detailed answers rather than half-filled fields. Each conversation is then summarized so product teams can read themes instead of paging through raw transcripts. Common placements include churn surveys when a customer cancels, onboarding feedback in the first week, post-purchase testimonials, weekly customer conversations, and pre-build research pulses.

Privacy is handled explicitly: conversations are encrypted in transit and at rest, readable only inside your Diaform workspace according to roles and per-project access, with SSO available on Enterprise. Customer data is not used to train AI models and can be exported as CSV or deleted at any time.

**Pricing & Plans:** Plans start with a free trial; pricing scales with the number of conversations you run, and Enterprise adds SSO and additional controls.

- **Adaptive AI follow-ups:** Each answer determines the next question, so the agent chases specifics instead of reading a fixed script — turning a vague 'it's fine' into the actual reason.
- **Natural voice or text interviews:** Conversations happen in natural-sounding voice or in text chat, and the voice starts immediately without awkward pauses, which keeps people talking to the end.
- **32-language coverage:** Respondents answer in the language they are most comfortable with, including English, German, French, Spanish, Japanese, Korean, Arabic, Hindi, and more, with no extra setup on your side.
- **Automatic answer summaries:** Every conversation is summarized into themes and recurring findings so your team gets actionable insight without reading every transcript.
- **Privacy and data control:** Conversations are encrypted in transit and at rest, access is governed by roles and per-project permissions, data is never used for model training, and responses export as CSV or delete on demand.

**Strengths:** Conversational follow-ups surface the reasoning behind answers that static forms never capture; Voice and text options make it easy for customers to say yes and finish the whole session; Automatic summaries save researchers hours of reading raw transcripts; Customer data is encrypted, never used to train models, and can be exported or deleted

**Limitations:** Best results require you to supply good context about your product and the questions you want answered; Conversation-based pricing means heavy research programs scale in cost with volume; Some advanced governance features such as SSO are limited to Enterprise

## Voiceform

Most survey tools force a trade-off: closed questions scale cheaply but capture shallow signal, while qualitative interviews produce rich detail but require a moderator for every session. Voiceform attacks that trade-off directly. You build an interview from multiple choice, Likert, matrix, checkbox, dropdown, and open-ended questions, choose whether respondents answer by voice, video, or text, add branding and conditional logic, and then launch the same interview to thousands of people simultaneously. The AI moderator asks dynamic follow-ups when an answer is vague, which is the part that normally requires a human researcher in the room.

Analysis is where the automation pays off. Responses arrive transcribed, translated, and themed without manual coding, with sentiment scoring and charts ready to export. The platform advertises more than 50 languages, so a single study can span global audiences, and results can be pushed to CSV, Excel, or audio downloads in MP3 and WAV. Teams can either bring their own participants through a shared link or embed, or draw on Voiceform's screened respondent pool.

For larger organizations there is an enterprise story: SOC 2 Type 2 and HIPAA compliance, SSO, two-factor authentication, role-based access controls, an API and SDK with sub-500ms responses and webhooks, and a stated 99.99% uptime target. Integrations connect findings to thousands of other tools, and case studies cite results such as 500 interviews in 72 hours, four times completion rates, and markedly longer open-ended answers. Pricing is quote-based through a demo or sales conversation, with a free trial entry point.

**Pricing & Plans:** Contact for pricing. Voiceform offers a free trial and routes paid plans through a demo or sales conversation; enterprise terms cover compliance, SSO, and API/SDK access.

- **AI-moderated interviews:** An AI moderator generates dynamic follow-up questions when an answer is thin, adding interview depth without a human moderator per session.
- **Voice, video, and text responses:** Respondents can answer by speaking, recording video, or typing, and teams can embed the same questions into existing survey platforms.
- **Automatic analysis pipeline:** Every response is transcribed, translated, and themed with sentiment scoring and charts ready to drop into a report.
- **50+ language support:** Built-in AI translation and transcription let one study reach audiences across more than fifty languages.
- **Enterprise controls and API:** SOC 2 Type 2 and HIPAA compliance, SSO, two-factor authentication, role-based access, and an API/SDK with webhooks and sub-500ms latency.

**Strengths:** Combines interview depth with survey scale in one workflow; Transcription, translation, sentiment, and theming happen automatically; Highly customizable question types, branding, and conditional logic; Enterprise-grade compliance, SSO, and a low-latency API and SDK

**Limitations:** No public price list; you need a sales conversation to get numbers; AI moderation quality still benefits from human review of themes and edge cases; Voice and video responses are inherently more effortful for respondents than plain text forms
