The Uxia alternative for testing the message behind the interface.
Uxia tests whether people can use a design. Articos tests whether the message lands: a panel of personas reacts to your positioning, copy, or concept and explains why. Peer-reviewed, under 30 minutes, about $10 per study.
14-day trial · 900 credits · No credit card
Recall against expert-published findings, validated against Baymard Institute and Nielsen Norman Group.
Full segment breakdown with reasoning per persona in every report.
Per study on Lite, Starter or Pro, at about 400 credits each. Uxia includes one free test; paid plans are priced through a demo.
Uxia shows whether people can use your design. Messaging decisions need to know why it lands.
Uxia is a UX research platform that pairs AI synthetic testers with human testers. It runs unmoderated usability tests on Figma prototypes, AI-built apps, live websites, and static designs, and returns heatmaps, task success rates, and think-aloud transcripts. It also runs AI-moderated interviews with human participants in 90+ languages, drawing on partner panels of 14M+ participants or your own users. Customers on its site include Philip Morris International, Blinkist, and Dassault Systèmes.
The gap shows up when the question is about the words rather than the clicks. Will a VP of Engineering believe this positioning line? Which of three concepts does each buyer type prefer, and what would change their mind? A usability test shows whether people complete a task on a design. A study asks a panel of personas to react to a message and explain why, then groups the objections by segment. Articos was built for that.

Articos runs the study end to end.
Hypotheses, a stance-diverse panel, interviews, and an evidence-traced report. Full report in under 30 minutes per study.
Message Testing
Segment reasoning for every variant.
Test up to 3 messaging variants in a single study. Each persona reacts independently and returns clarity scores, resonance signals, objection patterns, and the actual language your audience uses. Panels are engineered across five stance categories (Champions, Pragmatists, Skeptics, Blockers, Observers), so the study doesn't collapse into uniform approval.
Survey questions and tasks inside unmoderated tests, run by synthetic and human testers.
Concept Testing
Which segments preferred which, and why.
Compare multiple concept directions across buyer archetypes in one study. You see which segments preferred which concept and the reasoning behind each preference.
Static designs and prototypes tested with synthetic and human testers.
A/B Testing
Reasoning behind every preference.
Pre-launch testing for landing pages, hero variants, pricing pages, and ad creative. No traffic needed, no ad spend. Each preference comes with structured persona reasoning.
Not listed as a feature on its site.
User Interviews
50 personas, no recruitment, instant.
Interview up to 50 behaviorally diverse personas. The method is hypothesis-blind, so the interviewer doesn't steer toward the answer you hoped for. Follow up with Talk to Research for text questions, or start a live call for a real-time voice conversation with any persona.
AI-moderated interviews with human participants, with configurable probing, in 90+ languages. Synthetic testers produce think-aloud sessions inside usability tests.
ICP Discovery for B2B Roles
Any role. Any seniority. No panel to recruit.
Describe the audience and Articos builds the panel: software engineers, CISOs, procurement managers, C-suite buyers, RevOps directors. Roles and seniority are part of the study specification, not a filter on a panel.
Synthetic testers built from 15+ demographic filters, OCEAN profiles, and your own uploaded files (PDF, DOCX, PNG, JPG).
Reports That Ship
Client-ready, white-label, evidence-traced.
Every finding cites a specific persona quote, and every theme carries a confidence score. Six-stage adversarial review runs before findings land in your report. Export as PDF with white-label on Pro.
Unified reports combining synthetic and human results, plus chat with your data. The free test includes 5 insights and 1 full tester transcript.
Four moments when a design test is the wrong tool.
Peer-reviewed methodology, not persona prompting.
Skepticism about AI-generated research is fair, especially for tools where a persona prompt is the whole method. Articos works differently.
Personas are engineered from Big Five personality science (NEO-PI-R, 30 facets), Hofstede's six cultural dimensions across 69 countries, Rogers' diffusion model, and ACT-R cognitive architecture. Every interview is hypothesis-blind. Every finding runs through a six-stage adversarial review.
Validated against Baymard Institute and Nielsen Norman Group. Research Fidelity Index, 46 studies across 9 domains.
Validated across e-commerce, SaaS, healthcare, fintech, consumer mobile, education, enterprise, cross-cultural, and mixed research domains. Grounded Simulation peer-reviewed study, Articos Research (2026).
More accurate than prompting the same AI model directly. Five-condition comparison, p < 0.002 (Wilcoxon signed-rank).
Uxia says it calibrates its synthetic testers against human behavior using a “Golden Dataset,” and its site lists parity studies. Articos reports 86% recall against expert-published findings in a peer-reviewed study. The two measure different things, so compare the methods, not the percentages.
Two jobs where Uxia is the better pick.
Worth saying out loud.
Usability testing of designs.
Task success rates, heatmaps, accessibility checks, and think-aloud sessions on Figma prototypes, live sites, and static designs. Articos reasons about messaging and concepts. It doesn't watch anyone use an interface.
Synthetic and human testers in one workflow.
Uxia combines AI testers with human participants from a 14M+ panel and AI-moderated interviews in 90+ languages, and reports both together. Articos uses synthetic personas only and complements human research.
For everything else — B2B positioning, messaging depth, concept testing, user interviews, and decisions with no design to test yet — Articos is the fit.
