AI-Powered Usability Testing

Test with domain-expert personas, not generic participants

A developer tool needs feedback from developers, not a random testing panel. Tessary runs AI-powered usability testing with personas configured to match your actual users: their role, domain expertise, and behavioral context. Structured findings in minutes, not weeks.

The Problem

Finding participants with the right domain expertise is the real bottleneck.

For complex B2B products, generic testing panels can't reliably supply participants who understand your product. A developer tool needs developers. An analytics platform needs analysts. The result: wait times of 2–5 days for usable results, then hours watching recordings to extract three insights your team already suspected.

How It Works

Three steps from prototype to findings

No scheduling. No incentive coordination. No watching full session recordings to find one usable moment.

1

Configure a persona

Describe your target user's role, domain knowledge, goals, and familiarity with products like yours. Tessary's AI-assisted setup helps you shape a persona with the right behavioral context: a data engineer, a DevOps lead, a finance analyst.

2

Set the task

Paste your Figma prototype URL or live product URL. Write the task you want the persona to attempt, the same way you'd brief a real participant.

3

Get findings

Tessary runs the test in a real browser, navigating as your persona would. Within minutes, you receive structured findings: where the persona hesitated, what it missed, where it got confused, and why.

Side by Side

Not all "AI" in usability tools does the same thing

UserTesting's AI generates test plans. Maze's AI moderates interviews. Tessary's AI actually runs the test, acting as a domain-expert user on your prototype or live URL.

Key Benefits

Built for B2B SaaS sprint cadence

Test with the right expertise

Generic participant pools can't supply developers, operations managers, or finance professionals on demand. Tessary personas are configured with domain-specific knowledge so feedback reflects how your real users think.

Results before your next standup

Stop waiting two weeks for a panel, then another week for synthesis. Tessary returns findings in minutes — inside your sprint, not after it.

Replace the recruiting step entirely

Configure a persona once and reuse it across every design iteration. No coordinating schedules, managing no-shows, or compromising on participant criteria.

Reports your stakeholders can read

Findings arrive as structured reports with context for each issue, not raw recordings. Share directly with your team without a synthesis step.

FAQ

Common questions

Is Tessary accurate for complex B2B products?

Tessary uses a knowledge-grounded simulation approach that models role-appropriate behavior. A persona configured as a data analyst navigates your product with analyst-level familiarity, not as a generic internet user. This matters most for developer tools, analytics platforms, and workflow software where domain knowledge shapes how someone interacts with the UI.

Can Tessary test live products, not just prototypes?

Yes. Tessary runs tests in a real browser environment. You can test Figma prototypes and live URLs without any instrumentation on your side.

Does Tessary replace all user research?

Tessary replaces the usability testing step, specifically the part that requires recruiting domain-expert participants and waiting for results. For research that requires first-person narrative, emotional context, or discovery interviews, you still need real people. Tessary removes the recruitment bottleneck so you can test more often, not so you can skip research altogether.

How does Tessary compare to Maze and UserTesting?

UserTesting takes days and costs enterprise budgets, with results dependent on whoever their panel supplies. Maze gives you click data, not insight from someone who understands your specific product. For a full breakdown of where each tool fits, read our B2B SaaS usability testing guide.
