The Problem

Free testing tools miss the why

The User Interviews Research Budget Report found that 29% of research teams operate with under $25,000 per year for all user research. For most founders, that budget covers tools, recruiting, and analyst time combined. A free usability testing tool is not a luxury in that context. It is often the only way testing gets into the workflow at all.

The Gap

Where behavior ends, reasoning begins

The typical free tier offers a survey-based tool that asks participants to complete a task and rate the experience, or a behavioral analytics tool that shows where clicks went. Both catch obvious breaks in a flow. Neither explains what a specific user type was thinking when they hesitated before the primary CTA, or why the secondary option looked more trustworthy to them. To get that, the testing tool needs to reason from the perspective of a configured user, not a generic participant who has never seen your product category before.

The Free Plan

Three sessions per month, no credit card

Tessary's free plan gives founders and small teams everything needed to validate a flow before shipping. Three sessions covers a signup flow, an onboarding path, and one additional check. The findings arrive in minutes.

3 sessions per month, no credit card

The free plan includes three usability testing sessions per month with no credit card required and no trial expiration. Start testing a live URL or Figma prototype the same day you sign up.

Domain-aware AI personas

Configure the persona with your target user's role, expertise level, brand familiarity, and goals. The persona navigates as someone with exactly that background, not as a generic panelist drawn from a panel.

Structured findings with reasoning

Each session returns severity-ranked usability issues, screenshots showing where the persona hesitated, the full interaction steps taken, and a reasoning trace explaining each decision.

Works on live URLs and Figma

Point Tessary at your live staging environment, production URL, or Figma prototype. The persona navigates in a real browser, seeing exactly what your users see. No SDK or code changes required.

How It Works

Paste your URL. Get findings.

No scheduling, no participant coordination, no waiting for results that are already stale by the time they arrive.

  1. Paste your URL or Figma prototype link

    Tessary works on live staging environments, production URLs, and Figma prototype flows. No SDK or code changes required.

  2. Configure an AI persona

    Describe your target user: their role, what they already know about your product, their domain expertise, and their tolerance for unclear interfaces. The persona navigates as someone with exactly that background.

  3. Review structured findings

    Severity-ranked usability issues arrive in minutes, with screenshots showing where the persona got stuck, interaction steps, and a reasoning trace explaining each hesitation and decision.

Two Approaches

Tessary free vs. generic free tools

Most free tools return behavioral data: where users clicked, where they dropped. Tessary returns reasoning: why a specific persona hesitated, what confused them, and what to fix.

  • Task completion rates and click maps
  • Generic participant panels with no domain context
  • No reasoning trace: you see where, not why
  • No persona configuration for your specific user type
  • No coverage of Figma prototypes in all tiers

FAQ

Questions about the free plan

The free plan includes 3 usability testing sessions per month with no credit card required. Each session runs an AI persona through your live URL or Figma prototype in a real browser and returns structured findings, severity-ranked usability issues, screenshots, and a reasoning trace.
For directional questions (is this flow confusing, where do people stall, why are users dropping off at step 3), AI persona findings are reliable enough to act on within a sprint. For research requiring lived emotional experience or compliance-grade documentation, combine AI testing with occasional moderated sessions.

Tessary runs domain-aware AI personas in a real browser. The persona is configured to your target user's role, expertise, and context, not drawn from a generic pool.
