## Intervool

Intervool is built for product managers, UX researchers, and founders who run continuous customer discovery but struggle to keep what they learn usable. Instead of scattering calls across Drive folders and note apps, Intervool gives you one interview library: upload a recording, an audio file, or even plain notes, and the platform stores the media, generates a transcript, and surfaces structured takeaways such as pain points, opportunities, quotes, and feature requests. Every extracted item stays linked to the exact moment in the conversation it came from, so nothing becomes an unattributable assertion.

What makes Intervool more than an archive is the loop it closes. Insights roll up into evidence-linked themes, themes become concrete feature ideas, and those ideas land on a roadmap board you can view by MoSCoW priority, status, impact versus effort, or any custom single-select attribute like quarter or team. Dynamic personas and segments let you read each theme through the lens of who it came from, so you can see how needs differ between a seed-stage SaaS founder and an enterprise procurement lead rather than treating 'the customer' as one voice. A research Copilot answers questions such as what pain points are emerging most often or where the gaps in your research sit, and it answers with sources from your own library.

Intervool positions itself against repository-first tools like Dovetail, Condens, and Marvin, arguing that a tidy archive of findings is not the same as a closed decision loop. Pricing starts with a free 14-day trial: a Basic plan at $39 per month for one seat with 20 calls, a Team plan at $279 per month with six seats and 50 shared calls, and custom Enterprise pricing. Extra calls can be topped up for $15 per 10 calls, transcripts and insights are retained indefinitely, and video is kept for 90 days with extended retention available on request.

**Pricing & Plans:** Free 14-day trial. Basic $39/mo (1 seat, 20 calls/mo), Team $279/mo (6 seats, 50 shared calls/mo) plus $49 per extra seat, Enterprise custom. Top-ups available at $15 per 10 extra calls.

- **Interview library with transcript capture:** Upload video, audio, or notes for each customer call and get a stored recording, full transcript, and structured takeaways in one searchable repository.
- **Configurable AI insight extraction:** Define your own output types and a plain-English prompt per series, so each call surfaces exactly the pain points, opportunities, quotes, or feature requests you care about.
- **Research Copilot with sources:** Ask questions about your interviews, themes, and personas in natural language and get answers drawn from your own research with the underlying sources cited.
- **Themes, personas, and segments:** Insights cluster into evidence-linked themes, while dynamic personas and segments group the people behind each finding so needs can be compared group by group.
- **Evidence-backed roadmap board:** Turn themes into feature ideas and lay them out by MoSCoW, status, impact versus effort, or any custom attribute, each one a click away from the customer quote behind it.

**Strengths:** Closes the loop from raw interview to prioritized roadmap instead of stopping at an archive; Every insight and roadmap item stays linked to the source moment in the call; Highly configurable AI extraction with plain-language prompts and custom output types; Transparent, self-serve pricing with a free trial and low-cost call top-ups

**Limitations:** Per-seat and per-call limits mean larger research programs will need the Team tier or Enterprise; Video retention is capped at 90 days by default, which may not suit long-term archival needs; No free tier for ongoing use beyond the trial period

## Prolific

Prolific operates a marketplace where researchers and organisations post studies and verified participants complete them for payment. The pitch is quality over volume: instead of a massive but unvetted panel, Prolific verifies participants, applies attention and honesty checks, and lets requesters filter by detailed demographic, professional, and behavioural criteria. That makes it possible to target narrow, representative groups — for example coding experts, healthcare professionals, or specific national populations — which matters when a study compares groups or needs to generalise beyond a convenience sample.

In recent years Prolific has leaned heavily into AI. Its AI offering covers human preference data for fine-tuning and reinforcement learning, safety evaluation, red-teaming, and benchmarks across languages and tasks. It also publishes a leaderboard of model quality based on human evaluation, and offers developer-facing tooling such as a human-feedback API, agent workflows, and a Model Context Protocol server so AI pipelines can call for human input programmatically. Alongside this, the original academic and market-research business remains central.

Pricing is usage-based. Requesters pay for participant rewards plus a platform fee, and researchers either fund studies per response or talk to sales for larger programmes and managed services. Because rates depend on study length, targeting criteria, and volumes, published list prices are rare — the platform directs larger customers to a sales conversation.

**Pricing & Plans:** Usage-based for requesters: you pay participant rewards plus a platform fee, with custom quotes for large or managed programmes. Participants earn per completed study; joining is free.

- **Verified, targetable participant pool:** Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
- **AI data and human feedback:** Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
- **Built-in data-quality controls:** Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
- **Fast study launches:** Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
- **Participant side with guaranteed pay:** Participants get a clear per-study reward, flexible scheduling, and a minimum pay standard enforced by the platform.

**Strengths:** Strong focus on data quality with verification and attention checks; Granular targeting that supports niche and representative samples; Fast turnaround compared with traditional panel providers; Growing AI-focused tooling including a human-feedback API and MCP server

**Limitations:** Pricing is quote-based for many use cases, which makes budgeting less transparent up front; Participant availability in some narrow demographics can be limited or slower to fill; Costs add up quickly for large multi-country or longitudinal studies
