AI Prototyping Tools for SaaS Teams: What the Free Tiers Allow

AI prototyping tools turn a sentence, a sketch or screens that already exist into a flow you can click through, and five of them publish a free plan worth judging on real work before anyone pays: Uizard [1], Banani [2], Figma Make [3], Visily [4] and Alloy [5]. Banani describes what comes out as a prototype flow you click through to see how it works or feels from a user perspective [2]. Visily calls its version a navigable prototype, easily customized [4].

That's the line we draw around this stage. A tool belongs in it when the output navigates, so you can send a link and watch somebody walk from the second screen to the third unaided.

The sections below are sorted by what's already in your hands: a sketch, a sentence, a set of screens, or a product that already ships. Each one carries that tool's real free ceiling, quoted from the vendor’s own page and dated.

For the whole workflow this stage sits inside, the stage-by-stage AI design stack runs from first concept to the accessibility check.

What are AI prototyping tools?

AI prototyping tools generate several screens from a description, a drawing or an interface that already exists, then wire those screens together so the result can be clicked. Uizard’s line for Autodesigner 2.0 is that it generates multi-screen, editable prototypes in seconds using simple text [1]. Figma puts its version as describe it once, and Figma Make builds it with logic, layout and data [3].

The test that makes the category useful is navigation. Does the output move from one screen to the next on a click?

If it does, you're in this stage, and the result is testable with somebody who didn't draw it.

That test is also what keeps the stage cheap. A flow you can click settles the order of the steps and the labels on the buttons, and those are the two arguments that otherwise run for a week in Slack.

Can AI create a prototype?

Yes, and across several screens rather than one. Banani says you get multiple screens that visualize your product idea from a single prompt, then click through the prototype flow to see how it works or feels from a user perspective [2]. Visily’s Auto-Prototype analyzes your screens and creates a navigable prototype, which you can easily customize to fit your vision [4]. Uizard generates multi-screen, editable prototypes from simple text [1], and Figma Make turns ideas into interactive prototypes with AI [3].

So it's yes with a boundary on it. What comes back is a flow to test, and the production UI stays a separate piece of work: components, empty states, error copy, edge cases. Let the generated flow settle step order, and keep the real screen as a design job afterwards.

Every one of those descriptions is a vendor describing its own product, read on 23 October 2026.

Which tool fits your starting point?

Pick by what you already have. Here are the five, in the order the sections run, with each free ceiling in the same row as the thing the tool is good at. Nothing in it ranks them, and every figure names the page it came from.

Which AI is best for prototyping?

No measured ranking exists for these five, so this guide gives none. We ran no comparative test, and not one of the vendors publishes an independent measurement of its own output quality, so a score here would be our opinion dressed as a finding.

So the ranking question doesn't have an answer here. The starting-point question does.

What's left is the useful answer, which is the match to a starting point. Uizard takes a hand-drawn wireframe or a screenshot [1]. Banani takes one sentence [2]. Figma Make works inside the file where the team already comments [3], Visily starts from screens somebody drew [4], and Alloy starts from a product that has live users [5].

From a sketch to a clickable flow

Uizard starts from whatever is already on the whiteboard. Autodesigner 2.0 generates multi-screen, editable prototypes in seconds using simple text, and the same product digitizes a hand-drawn wireframe and converts a screenshot into an editable mockup [1]. If a flow is sketched on a wall, that's the shortest route from the wall to something clickable.

The free plan is where this guide goes past a one-line mention. Uizard’s pricing page caps Free at 3 AI generations per month, 2 projects and 10 free templates, and names the AI engine on that plan as Autodesigner 1.5 [1].

Read that engine line twice before you plan a trial around it. The free tier runs an earlier generation of the thing the product page describes, so a trial there teaches what 1.5 does [1].

Paid plans are published, which makes this one easy to budget. Free sits at $0, Pro at $12 per month, Business at $39 per month, and Enterprise is custom [1]. Both middle figures carry billed annually on the page [1], so ask for the month-to-month rate before you compare them with anything else.

From one sentence to a flow

Banani starts from a prompt. It generates design prototypes using natural language and references you like, hands over multiple screens that visualize your product idea from a single prompt, and lets you click through the prototype flow to see how it works or feels from a user perspective [2]. The result moves to Figma in 1 click [2].

The free plan carries 12 monthly credits and 3 daily credits, asks for no credit card, and the page says it never expires [2]. Beside those figures Banani notes that a single generation typically costs more than 1 credit, depending on the complexity of the task [2].

So read 12 as the ceiling and expect fewer than 12 goes.

Above the free plan, Plus reads $12 a month and Pro $30 a month [2]. The page carries a yearly and a monthly view, and a struck-through list price sits beside each paid tier, so confirm the monthly rate before budgeting on it.

How do I create a prototype in Figma?

In Figma, the AI route to a prototype is Figma Make. Figma’s page for it says turn ideas into interactive prototypes with AI, and describe it once, and Figma Make builds it with logic, layout and data [3]. Figma’s own FAQ answers the cost question directly: you can try Figma Make for free on the Starter plan, and advanced features are available on paid plans [3].

The pricing page lines up with that today. Starter is free and lists unlimited drafts, UI kits and templates, and 150 AI credits a day up to 500 credits a month [3]. Prompting the model is marked as included on Starter, while some Make features sit on paid plans, among them turning a Make preview into design layers to paste and edit in Figma Design [3]. A Professional Full seat is $16 a month and carries 3,000 AI credits a month [3].

So there's a free way in, and what runs out is a credit allowance. That's the same shape as the other four.

From screens you already have

Visily starts from drawings that exist. Auto-Prototype analyzes your screens and creates a navigable prototype, which you can easily customize to fit your vision, and Visily describes the output as clickable app and website prototypes [4]. Once a wireframe is in the tool, this is the step that makes it walkable.

The free Starter plan is roomy on credits and tight on space. Starter is $0 with 300 AI credits a month, 2 editable boards per workspace, 2,500 elements per board, 150 template credits a month and 50 workspace members [4].

That combination decides how you'll use it. Credits are plentiful and boards are not, so the ceiling it meets first is project count. One board per flow, finish it, archive it.

Above Starter, Pro runs $14 per editor a month with 3,000 AI credits a month, and Business runs $29 per editor a month billed annually with 10,000 AI credits a month [4].

Against the product you already ship

Alloy starts from the product itself. Its line is AI prototyping with your real product, and the method is to capture your product from the browser and make changes with chat [5]. What you share is the live UI with the change in it, which is a different starting point from a blank prompt.

Once a product has customers, that's often the realistic case. The flow you want to test is already half built, and the open question is what one screen should do differently.

The free plan is $0 with unlimited users and $5 of credits per user a month, plus unlimited sessions, unlimited viewers and external sharing [5]. Pro is $20 per user a month and includes $20 of credits per user a month and code export [5].

Credits priced in dollars make this allowance hard to line up against the other four, and we'd rather say so than build a comparison out of units that don't convert.

Can you build a prototype with AI for free?

Yes, on all five, and free here means metered. Every plan below is real, every one is capped, and the caps are written in four different units.

One pattern runs the length of that table. Every free plan is a metered allowance, and the meters read in generations, credits a day, credits a month and dollars of credit, which don't convert into each other.

So the comparison that survives is the one against your own next flow. Count the screens it needs, read the ceiling in the row, and start where the two numbers fit.

How we checked these free tiers

Every feature, price and limit in this guide comes from the vendor’s own product or pricing page, and we read all ten of those pages on 23 October 2026. All five references are therefore vendor primary sources, the weakest kind of source a claim like this can rest on, and the reference list labels each one that way.

No comparative test sits behind this guide, and no quality ranking comes out of it.

One page disagreed with itself, so here's how we read it. Banani’s visible Free column says 12 monthly credits and 3 daily credits, the structured data embedded in the same page says 20 monthly credits and 5 daily refills, and we quote the column a reader actually sees [2]. Figma’s FAQ and its plan comparison agree today that Figma Make can be tried on Starter, and the figures above come from both [3].

Credit allowances and prices move, which is why every figure here carries the date we checked it. If you're reading this months from now, the vendor page is the authority and this guide is a starting point. There are no affiliate links in it.

Where AI prototyping stops

Four limits run across all five tools, and the figures behind them are all on the pages cited here.

Free means metered.

Uizard caps its free plan at 3 AI generations a month [1], Banani at 12 monthly credits and 3 daily [2], Figma Starter at 150 AI credits a day [3], Visily Starter at 300 AI credits a month and 2 editable boards [4], and Alloy Free at $5 of credits per user [5]. Every one is a genuine way in, and not one is a free quarter of work.

A generated flow is enough to settle step order and to test with a handful of users, and it isn't the production UI. Your components, empty states, error copy and the design system are all still design work once the prototype has done its job.

The engine behind a free plan can be older than the one the product page describes. Uizard names Autodesigner 1.5 on its free tier while its product page describes 2.0 [1], so a trial there measures the older model.

None of the five publishes an independent measurement of its output quality. Every capability claim above is a vendor describing its own product, which is why there's no score and no winner in this guide.

The only quality judgement worth having is the one your own team runs, on one real flow.

Cluma pairs senior designers with AI and tooling for speed, which is set out on the AI excellence page and in more detail on the technology page. Product design, prototypes and design systems run in uShip, the SaaS UI/UX design agency side of Cluma, and the work is design only, so your engineers implement what gets designed.

Everyday graphic design tasks come back in about 48 hours, and bigger product and website projects move milestone by milestone, with progress roughly every 48 hours in a shared board.

The rest of our playbooks sit on the Cluma guides page.
