For designers
Watch someone use it before it ships
Paste a prototype link or a live URL. Fiuto writes the usability test, runs it with AI respondents and real people, and reads back where they hesitated, what they clicked, and what they said about it.Free to start, in minutes, every method on every plan.
How it works
Fiuto runs your full research loop
Paste a URL and Fiuto takes it from there. No research experience needed.
What a design decision needs before it ships
A design review is a room full of people who already know what the screen is supposed to do. That is exactly the group least able to tell you whether a stranger can figure it out. You already have opinions about whether the flow works. What you need is someone who has never seen the file.
Fiuto turns a design question into a task someone else actually performs: find the setting, complete the checkout, sort these features into groups that make sense to you. It drafts the test from the prototype, runs it, and reads back the behaviour and a short explanation together, so a hesitation shows up next to the respondent's own words about it, not as a separate number to reconcile by hand.
What designers test first
A flow, a structure, or a first impression. Each one is a study Fiuto can draft from your file in minutes.
Can they get through the flow?
Give people a task on a clickable prototype or the live product and see how they get through it, or where they stop. Explore prototype testing.
Do the categories match how people think?
People group and name your content, and you see whether your structure and labels match theirs before the rename ships. Explore card sorting.
What lands in five seconds?
Show the screen briefly and ask what stuck. A five-second test tells you what a first look actually communicates. Explore five-second testing.
Which direction should survive?
Show two or three directions, ask which one people would choose, then ask why. Taste becomes a decision you can inspect. Explore preference testing.
What you get as a designer
The whole research loop, run for you, while the file is still cheap to change.
A test drafted from your prototype, not a blank builder
Paste the link and say what you need to learn. Fiuto reads the flow and drafts the task, the follow-up questions, and the screening, for you to review before it launches.
AI respondents go first
A cast of AI respondents works through the prototype before anyone else, so you get a first read in minutes and catch a broken link or an unclear task before real people see it. Up to two of the cast can be AI experts in conversion, usability, copy or SEO, on every plan including Free.
Real people, recruited or your own
Describe the audience you need and Fiuto recruits it from Prolific's global panel, with demographic filters. Or share the link with your own users and customers. Runs are labelled by who answered.
Behaviour and explanation together
Every task is paired with a short follow-up, so a completion rate and the words of the people who struggled come back attached to the same response, with the paths and clicks alongside.
Every method, on every plan
Prototype and live-website tasks, first-click, five-second, preference, card sorting, and tree testing, 18 methods in all, every one on the free plan. Testing an early idea never waits on a budget approval.
Templates you keep
Start from one of Fiuto's templates, or save your own studies as templates and reuse them, so the second usability test on the same product takes a minute to set up.
Unlimited collaborators, so the readout reaches the whole team
Fiuto's price is per account. Share results, findings and decks with as many collaborators as you like on every plan, including Free. Nobody needs a licence to open them.
MCP for user research
Your data is yours. Stay in Claude Code
Prototyping in v0, Lovable, Bolt, or Cursor? Ask the agent to create, launch, and read back the usability test over MCP, in the same session. Every result is yours, out as CSV or JSON through a per-study token, the API or MCP, on every plan including Free.

The free plan needs no card: every test method, card sorting and tree testing included, 1 live study a month, 10 responses per study, and 600 AI credits a month, with the AI drafting, the AI respondents, and the findings all included. Core is $29 a month, flat per account, with 3 live studies a month, 100 responses per study, and 3,000 AI credits. Pro is $69 a month with 10 live studies, unlimited responses per study, and 12,000 AI credits.
Share a study, its results or its deck with as many collaborators as you like, on every plan including Free, and export the raw data as CSV or JSON on any of them. Upgrade, downgrade or cancel any time from the billing page, with no sales call at any step. Recruited participants are paid for on top of the plan, and the total is shown before you order.
Frequently asked questions
01Do I need a finished prototype to run a usability test?
No. Card sorting works from labels alone, a five-second test from a single screen, and a prototype test from an early clickable version. Test the decision while the file is still cheap to change.
02Can I test a Figma prototype?
Yes. Paste the prototype link and Fiuto builds the task around it. A live website works the same way from its URL, so a shipped flow gets the same scrutiny as a mockup.
03What is the difference between a first-impression test and a usability test?
A first-impression test, such as a five-second test, shows what people notice or remember from a brief look. A usability test gives them a task to complete on a prototype or live site and records how they get through it, or where they stop.
04Can I see where someone hesitated, not just whether they finished?
Yes. Fiuto pairs a task with a short follow-up question, so you get the completion and the moment the respondent describes as confusing, in their own words, on the same response.
05Is card sorting available on every plan?
Yes, on every plan including Free, the same as every other method. Tree testing too.
06Does Fiuto recruit participants?
Yes. Describe the audience you need and Fiuto recruits it from Prolific's global panel, with demographic filters. You can also share the study link with your own users, customers, or community, and the two kinds of run stay labelled separately.
07Is it free to start?
Yes. The free plan includes every test method, 1 live study a month, 10 responses per study, and 600 AI credits a month. No card, no time limit.
08Does 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 across 18 methods, with AI respondents first and real people after.
09Can I change or cancel my plan without contacting anyone?
Yes. You can upgrade, downgrade, or cancel your subscription at any time from the billing page in the app. There is no sales conversation at any step, from the free plan onwards.
