Recall against expert-published research findings — validated against Baymard Institute and Nielsen Norman Group.
From message variants to a shippable report — per test.
Effective cost on the Pro plan. Unlimited message tests, no credit ceiling.
Agencies, SaaS teams, and consultants using Articos to test messaging before launch.
Most messaging ships without being tested. So it ships on gut.
The hero headline gets rewritten six times, debated on Slack, and shipped on whichever version won the last meeting. Three ad variants sit in a Google Doc until the team picks the one that “feels right.” The email subject line goes out with whichever version someone wrote at 11pm on Tuesday.
Traditional message testing takes 2 to 4 weeks and costs thousands per round through research panels. So teams reserve it for the campaigns big enough to earn the budget. Everything else ships on instinct, which means everything else is a bet.
You'll learn which one lost — after paid spend already paid for the lesson.
Message testing you can afford to run on every ship.
A message test on Articos takes 30 minutes and costs $8. Drop in three variants of any messaging asset, define the audience, and get back a structured report with clarity per variant, segment-level winner, and the exact language your audience uses.
That economics shift changes what you test. The category launch still gets one. So does the email subject line, the retargeting ad, the LP hero variant, the pricing page hook, and the LinkedIn post the CEO wrote last night. Same architecture every test.
Six recurring message tests, one platform.
The work most teams skip because a panel test isn't budget-defensible now runs in 30 minutes at $8. Test ad copy, email, headlines, taglines, value props, and CTAs on one message testing tool. Same rigor every time.
Test three ad concepts before paid spend goes live.
Meta, Google, or LinkedIn creative. Find the duds before CAC absorbs them.
Testing 3 LinkedIn ad hooks for a fintech launch. Get the winner in 30 minutes.
Validate the email before it hits 50,000 inboxes.
Three subject lines, three body framings, or three CTAs. See open likelihood and objections per segment.
Nurture sequence email A/B/C. Ship the version that earns the reply, not the one that sounded clever in review.
Validate your value prop before the homepage rewrite.
Multiple framings side-by-side. Get clarity, resonance, and the exact words your audience uses.
SaaS team testing 3 value-prop framings. Find out which converts your ICP and which confuses them.
Pick the hero headline before creative production begins.
Two or three hero variants tested for clarity, resonance, and segment-level preference.
Growth team testing 2 headlines for a paid landing page. Kill the underperformer before traffic teaches you.
Test taglines and positioning before committing the GTM.
Two or three hypotheses tested against your audience before the launch deck or website rebuild.
"Category leader" vs "cheaper alternative" vs "AI-native challenger." See which one your ICP can repeat back.
Pick the CTA that converts, not the one that sounds clever.
Three CTAs tested against the exact segment about to see them, with click likelihood and reasoning per persona.
"Get Started" vs "Book a Demo" vs "See How It Works." Ship the one that earns the click.
Four steps. Thirty minutes. One report you can ship.
Articos works as an automated message testing platform — comparing up to three variants against synthetic audiences before the message goes live.
Upload up to three versions of one message — ad copy, subject lines, headlines, taglines, value props, positioning lines, or CTAs. Articos handles them as a single comparison test, not three separate studies.
Select role, seniority, industry, company size, geography, and buyer stage. Articos generates 12 to 50 synthetic personas, including five built-in dissenters per panel calibrated to push back on your message.
Each persona reacts independently, hypothesis-blind. They can't see your winning criteria or each other's responses. Architectural bias control, not moderator training.
Findings per variant — clarity score, resonance, objection patterns, language your audience uses, and the winner with reasoning per segment. Evidence chains cite every finding to a specific persona quote. Export as PDF, white-label for client delivery.
A report you'd ship to a client or a board.
Every message test returns a structured report, not a transcript dump. Built for the room where the decision gets made — an exec review, a client pitch, or Monday morning stand-up.
Clarity, resonance, believability, and segment-level reactions.
Which variant wins for enterprise buyers, SMBs, decision-makers, or price-sensitive segments. Separately, not averaged into a single winner that hides the trade-off.
Each finding traces back to a specific persona, a specific question, and the exact quote that generated it.
Know which findings hold across personas, and which need a closer look.
Your logo, your colors. Ship the PDF to a client, a board, or your CEO without rewriting a line.
Same AI everyone uses. Completely different architecture.
Articos is the only AI message testing platform with a peer-reviewed validation paper. Personas are built on Big Five personality (NEO-PI-R, 30 facets), Hofstede's six cultural dimensions across 69 countries, Rogers' diffusion model for stance diversity, ACT-R cognitive architecture, hypothesis-blind interviews, and a six-stage adversarial review pipeline.
Recall against expert-published findings, validated against Baymard Institute and Nielsen Norman Group.
Validated across e-commerce, SaaS, healthcare, fintech, consumer mobile, education, enterprise, cross-cultural, and mixed research domains.
More accurate than prompting the same AI model directly. Same model, different architecture.
