vsUserTesting

Research method

Diaform

AI-led text or voice interview on your own audience. Synthesis (sentiment, themes, quotes) is generated per response.

UserTesting

Recorded video sessions with recruited panel participants, typically 15-60 minutes each, watched and tagged by the team.

Recruiting (you bring vs they provide)

Diaform

Bring your own audience: customers, trial users, list, in-app. Share one link via email, Slack, QR, or in-app prompt.

UserTesting

UserTesting recruits from a deep proprietary panel, hard-to-reach personas, demographic targeting, full screener pipeline.

Pre-screened demographic targeting

Diaform

No built-in panel screening, you control who you send your link to from your existing audience or CRM segments.

UserTesting

Pre-screened demographic and behavioral targeting on millions of panelists. Best-in-class for sourcing specific user types.

Recorded video sessions

Diaform

Captures voice + transcript + synthesis per conversation. No live observed video room or recorded screen-share session.

UserTesting

Recorded video, screen, and audio for every session, with timestamped highlights and stakeholder observation rooms.

Live AI-led interviews

Diaform

AI runs every interview live with adaptive follow-ups (1, 3, or 5 deep). No researcher needs to be in the room.

UserTesting

Sessions are usually unmoderated tasks or human-led calls. AI assistance helps with synthesis after, not in flow.

Cost per session

Diaform

Each conversation costs cents inside your monthly plan. 150 conversations included on the trial; thousands feasible per month.

UserTesting

Each panel-recruited session carries an incentive plus platform overhead. Adds up fast for high-volume continuous research.

Time to first session

Diaform

Minutes from signup to a live AI-led interview link. 14-day trial available immediately.

UserTesting

Days from study setup to first completed session, recruiting, screener review, and scheduling all take time.

Voice

Diaform

Whisper voice input + ElevenLabs AI voice in 30+ languages. Voice answers are typically 2-3× longer than typed.

UserTesting

Spoken responses are core to the recorded-video format, natural voice from every participant in every session.

Pricing transparency

Diaform

Public pricing: Pro $89/mo ($74/mo annual). Business $149/mo ($124/mo annual). 14-day trial

UserTesting

Enterprise contracts, typically $20k-$100k+/yr. Pricing is demo-gated and negotiated, not designed for self-serve evaluation.

Best for

Diaform

Continuous research on your own users, churn, onboarding, concept tests, JTBD, running every week, not every quarter.

UserTesting

Hard-to-reach personas, observed live sessions for stakeholders, and one-off deep usability studies funded as projects.

Two different research models

UserTesting is the time-tested qualitative platform: recruited panels, scheduled sessions, hours of recorded video. Enterprise pricing, enterprise SLAs, and the ability to talk to people you'd never reach otherwise.

Diaform flips the model. You bring your own audience (customers, trial users, list, in-app); the AI runs a structured interview at any scale; the synthesis arrives the same day. Cheaper per conversation, no scheduling, no panel.

Where UserTesting may be heavy

Enterprise pricing

UserTesting contracts often run into the tens of thousands annually. Hard to justify for a single PM or a small SaaS team.

Hours of video to watch

Sessions are recorded video. Highlights help, but the synthesis still takes time, often more than the interviews themselves.

Panel recruits, not your customers

The panel gives you reach but not the people who actually use your product. For B2B SaaS, that gap is meaningful.

Where Diaform differs

AI runs instead of a panel session

Adaptive AI follow-ups (1, 3, or 5 deep) per response, research-grade interviews without the scheduling.

Synthesis built in

Sentiment, confidence, keywords, and notable quotes per conversation. No watching hours of video.

Run on your real users

Share one link via email, in-app, Slack, or QR. Customers and trial users, exactly the people who matter.

Triggered actions in flow

13 topic + 5 sentiment triggers can alert Slack, capture an email, offer a discount mid-interview.

Voice or text in 30+ languages

Voice answers are 2-3× longer; native ElevenLabs voice and Whisper input make it feel like a real interview.

Transparent SaaS pricing

14-day trial. Pro $89/mo ($74/mo annual). Business $149/mo ($124/mo annual).

Pick the right tool for the job

When UserTesting is the better fit

Reach for UserTesting when you need participants you can't reach yourself, testing a market you don't have customers in yet. It's also the right tool when you want live, observed video sessions with real-time observation rooms so stakeholders can watch interviews as they happen.

When Diaform is the better fit

Diaform is the better fit when you already have the audience, customers, trial users, email list, in-app, and want qualitative depth without the panel cost. It's built for continuous research: churn calls, onboarding feedback, concept tests, and JTBD running every week instead of every quarter.

Frequently asked questions

Q

Does Diaform recruit participants?

No. Diaform is bring-your-own-audience: customers, trial users, list, in-app. UserTesting is the right pick if recruiting is the constraint.

Q

How does pricing compare?

UserTesting is enterprise contracts, typically $20k–$100k+/yr. Diaform is published: Pro $89/mo, Business $149/mo, with a 14-day trial for buyers who want to evaluate before contracting.

Q

Can I get the depth of a recorded session?

Diaform captures voice answers, transcripts, sentiment, themes, and notable quotes per conversation. You don't get an observed live video, but you get most of the analytical signal, at far higher volume.

Q

Can both run together?

Yes. Many teams use UserTesting for occasional live sessions with the panel, and Diaform for ongoing AI-led research with their own users.

Q

Will my data train AI models?

Diaform does not use customer conversation data to train AI models.
