What you get with Fiuto
The rehearsal and the answer in one place, on a plan you open yourself today.
AI respondents first, real people after, on every plan
Up to five AI respondents go through the study first, up to two of them experts in conversion, usability, copy or SEO, so you get a read in minutes and catch a bad task before anyone else sees it. Then the same study goes to real people from Prolific's global panel, priced per response with no quote, or to your own users by link. The AI pass is the rehearsal. The real pass is the answer.
Eighteen methods, not one interview
Card sort, tree test, first-click, five-second and preference test, click heatmaps, live site and prototype tasks, copy tests, surveys and open text, mixable in one study on every plan including Free. An interview asks what someone thinks they'd do; a first-click test records where they went. AI interviews are an upcoming feature.
A free plan today, not an annual commitment
Free needs no card and carries 1 live study a month, 10 responses per study, 600 AI credits and every method. Core is $29 a month and Pro is $69, and you change or cancel from the billing page. Synthetic Users' pricing page says plans start at $12,500 a year.
Your data is yours
Every response, click, rating and recording is readable per person, and exportable as raw CSV or JSON, over a per-study API token, or over MCP, on every plan including Free. Findings, a readout and a deck you can share with as many collaborators as you like.

| Fiuto | Synthetic Users | |
|---|---|---|
| Free plan | Every method, 1 live study a month, 10 responses per study, 600 AI credits a month, no card. | Not published. Its pricing page names no free plan and no trial, and offers a 30-minute demo instead. |
| Paid plans | Core $29 and Pro $69 a month, published, flat per account. Upgrade, downgrade or cancel from the billing page. | Annual only. Its pricing page says plans start at $12,500 a year, sold as one pool of research tokens rather than as named tiers. |
| Collaborators | Share with as many collaborators as you like on every plan, including Free. | Its pricing page says collaborative seats are always unlimited. |
| Unmoderated methods | 18 method blocks, every one on every plan. Card sort, tree test, first-click, five-second, preference test and click heatmap among them. | Problem exploration interviews, concept testing and custom script interviews, all answered by synthetic participants. No card sort, tree test, first-click, five-second or preference test. |
| AI moderator | Upcoming. AI interviews are in development, and this row will list them the day they are out of alpha. | Both sides of its interview are AI: the questions and the answers. |
| AI respondents | Up to five per run on every plan including Free, up to two of them experts in conversion, usability, copy or SEO. Then real people answer the same study. | The whole product. Synthetic participants enrichable with your own documents, per its pricing page. |
| Study drafting | AI drafts the whole study from your URL and goal, on every plan including Free. | Custom script interviews let you bring your own guide, and its templated study types set the questions otherwise. |
| MCP server | Read and write: create, launch and read results from seven coding agents, plus an API, on every plan including Free. | No MCP server published. It documents an API with Python and TypeScript SDKs. |
| Recruitment | Prolific's global panel across 38+ countries, priced per response with no quote. Or share the link with your own people. | None, by design. Its pricing page lists participant recruitment as not needed, because the participants are generated rather than found. |
| Instrumented build | @fiuto/runner is on public npm and attaches to any live URL. Clicks and events come back in the same export as the answers. | Not published. Its pricing page says a live website can be shown as stimulus inside an interview. |
| Templates and product memory | 24 curated templates plus the ones you save, on every plan. Fiuto remembers your product, your audience and what you're trying to learn between studies. | Your own documents can enrich a participant. Study templates and cross-study memory not published. |

Frequently asked questions
Is Fiuto a Synthetic Users alternative?
Yes, for small teams that want the AI pass and the real-people pass on the same study, at a published price. Fiuto sends up to five AI respondents through the study first, then puts it in front of real people from a global panel with no quote, across eighteen unmoderated methods, from a free plan with no card.
Does Synthetic Users have a free plan or a published price?
It publishes a floor and no free plan, as of 11 September 2026. Its pricing page says plans start at $12,500 a year, sold as one annual pool of research tokens, with a 30-minute demo as the call to action. Fiuto's free plan needs no card and runs 1 live study a month with every method and the AI included, and Core and Pro are $29 and $69 a month on the pricing page.
Are Fiuto's AI respondents the same thing as synthetic users?
The same idea, used for a different job. Fiuto's AI respondents rehearse the study so you catch a confusing task early, and up to two of the five can be experts in conversion, usability, copy or SEO judging the surface. Then real people answer the same study, and their clicks and words come back in the same export.
Does Fiuto run AI interviews?
AI interviews are an upcoming feature, in development now, and this page will list them the day they are out of alpha. Until then Fiuto runs unmoderated studies, with AI respondents first and real people after.
Can I export my data from Fiuto?
Yes, on every plan including Free. Raw CSV and JSON export, a per-study API token, and the same data over MCP. Your data is yours.
Which methods does Fiuto support?
18 method blocks on every plan: prototype and live website tasks, first-click, click heatmap, five-second tests, preference and design feedback, card sort, tree test, matrix, ranking, rating scales, open text, and copy tests among them.
