Where we stand

Synthetic Users built one flexible interview tool. Operators needed dedicated workflows.

Synthetic Users built a strong interview platform — multi-agent architecture, OCEAN-grounded participants, 21 peer-reviewed papers, customers like TikTok and JPMorgan. For broad qualitative discovery, it's the credibility you'd want. But every study starts from a blank script. Articos is built for the cadence you're already shipping at — same synthetic category, peer-reviewed methodology, with the workflow already configured.

What you run

Every research job you'd run on Synthetic Users. Built around the workflow, not the interview.

Articos isn't a single interview tool reconfigured per study. It's the full synthetic-research stack, with dedicated surfaces per job — all in under 30 minutes per study.

Concept Testing

Validate messaging variants in a single study.

Drop in up to three variants of ad copy, email subject lines, CTAs, hero headlines, value props, or positioning lines. Each persona reacts independently — clarity scores, resonance, objections, the language they'd actually use. Compare across segments in one pass, not three configured interviews.

Synthetic Users: configured interview per concept, OCEAN-grounded participants, per-interview pricing.

Message Testing

The recurring job most teams skip on a per-interview ceiling.

Headlines, ads, LP copy, full pages. Articos runs each persona blind to your hypotheses, then returns clarity scores, resonance, objections, and the language patterns your audience uses. Five drafts in parallel, no script writing required.

Synthetic Users: covered through Custom Script Interviews, billed per participant.

A/B Testing

Every A/B test starts with a question: which version wins?

Pre-launch testing for LPs, hero variants, pricing pages, and creative. No traffic needed, no spend. Get structured persona reactions and the "why" behind each preference — before you push to paid.

Synthetic Users: not a named capability — would run as a Custom Script comparison.

User Interviews

Your audience, mapped without recruiting anyone.

Up to 50 behaviorally diverse personas, each interviewed in an isolated session. Hypothesis-blind methodology. Follow up with Talk to Research — ask any persona any specific question.

Synthetic Users: 10–12 participants typical, OCEAN-grounded with multi-agent architecture.

ICP Discovery

Articos's superpower — including the segments panels miss.

Build personas for any role, seniority, industry, and geo. Test which patterns convert. Cultural intelligence built in — a CISO in Frankfurt doesn't sound like a CISO in Singapore.

Synthetic Users: covered through their participant builder, OCEAN dimensions only.

Reports That Ship

Evidence-traced, white-label, client-ready.

Every finding cited to a specific persona quote. Confidence scores on every theme. Six-stage actionability label for client delivery. Your logo, your colors, your voice.

Synthetic Users: structured report with executive summary, themes, and verbatim quotes — designed for stakeholder sharing, not white-label client delivery.

Where Synthetic Users strains

Four moments Synthetic Users wasn't built for.

01

Teams running multiple researches per month

Synthetic Users prices per interview, $2 to $60 — designed for the project-based studies UX researchers run at landmark moments. A marketing team running 8 message tests, 3 ICP studies, and 2 landing page comparisons in a quarter hits real four-figure spend before the work is done. Per-interview accounting becomes the bottleneck.

With Articos

One $199/mo Pro subscription, unlimited research. Run the test on Tuesday, the next one on Thursday, no per-interview math in between.

02

Recurring jobs without recurring setup

Synthetic Users hands you a script editor and a participant builder. The fifth message test this month starts from the same blank script as the first. For broad qualitative discovery, that flexibility is freeing. For high-frequency operator workflows, the configuration overhead compounds.

With Articos

Dedicated workflows per job. Message testing opens to a variant-comparison surface. Landing page testing opens to a two-variant uploader. Configuration designed once, used every time.

03

Decisions that hinge on cultural or behavioral nuance

Synthetic Users grounds personas in OCEAN — the Big Five personality model. Strong foundation, but a single layer. For positioning research across US and APAC, feature validation involving switching costs, or pricing decisions sensitive to organizational hierarchy, single-factor grounding sits one layer shy of what the research requires.

With Articos

Big Five (NEO-PI-R, 30 facets) + Hofstede's six cultural dimensions across 69 countries + Rogers diffusion of innovations + ACT-R cognitive architecture. Four behavioral science layers stacked.

04

Buyers asking "where's the paper that validates this product?"

Synthetic Users cites 21 peer-reviewed papers supporting the synthetic research thesis. Strong evidence for the category — but category-level. The papers validate that synthetic research as a methodology works across multiple products, not that any specific product matches expert findings.

With Articos

The Grounded Simulation paper validates Articos specifically at 86% recall against expert-published research from Baymard Institute and Nielsen Norman Group, across 46 studies in 9 industries. Peer-reviewed evidence of the product itself, not the category.

Grounded in science

Same category. Deeper methodology stack — proven on paper.

Articos and Synthetic Users sit in the same category: synthetic personas grounded in behavioral science. Both reject the ChatGPT approach. Both validate against established research. The difference is what's under the hood. Articos layers Big Five personality (NEO-PI-R, 30 facets), Hofstede's six cultural dimensions across 69 countries, Rogers' diffusion of innovations, ACT-R cognitive architecture, hypothesis-blind interview design, and a six-stage adversarial review pipeline. Same AI models everyone uses. Completely different architecture.

The honest part

Two reasons you might prefer Synthetic Users.

Worth saying out loud.

01

RAG-grounded studies with proprietary data.

If your research depends on grounding personas in your own customer transcripts, support tickets, sales call recordings, or other proprietary data sources, Synthetic Users' RAG-grounded studies feature is built for that pattern. Articos's grounding is in behavioral science and validated published research — not customer-specific corpus data.

02

Open-ended exploratory research without a defined hypothesis.

If your research starts without a clear question — pure problem-space exploration where you want personas to lead the conversation in any direction, with no pre-defined job to validate — Synthetic Users' open-script format fits that pattern. Articos's workflows assume you have a job to run (test these variants, validate this idea, map this ICP). For research that's genuinely undirected, their format gives the personas more room to wander.

For everything else — message testing, concept testing, ICP discovery, positioning, A/B tests, user interviews — the choice is structural, not loyalty.

For recurring research jobs — message testing, landing page testing, concept validation, ICP discovery, positioning research — yes. For broad qualitative discovery with custom interview formats or RAG-grounded proprietary data, Synthetic Users is built for that pattern and we don't pretend otherwise. Many customers run both for different research moments.
Synthetic Users cites 85–92% synthetic-organic parity supported by 21 peer-reviewed papers about the synthetic research category. Articos has its own peer-reviewed paper — the Grounded Simulation paper — validating Articos specifically at 86% recall against expert-published research from Baymard Institute and Nielsen Norman Group across 46 studies in 9 industries. Two evidence standards: category-level vs product-level. Both transparent.
Pricing model, not unit cost. Synthetic Users prices per interview ($2–$60). Articos prices per research, which includes the full persona panel (12–50 personas) and the structured report — $8–$20 effective on Pro. The Pro plan is unlimited. For a team running 5+ studies per month, the math diverges quickly.
At 86% recall against expert-published research findings across 46 validated studies in 9 industries, benchmarked against Baymard Institute and Nielsen Norman Group. 7.5× more accurate than bare-prompting the same AI model. The Grounded Simulation paper documents the methodology and the gap closure.
No. Articos is used across B2B and broader contexts — agencies running consumer brand work, SaaS teams across product and growth, founders validating early ideas, consultants on client engagements. The validated studies span finance, healthcare, fintech, consumer mobile, education, enterprise SaaS, and cross-cultural research.
Pattern mismatch. Synthetic Users is built around the flexible interview tool — designed for broad qualitative discovery configured per study. Agencies and SaaS teams running recurring jobs (message tests, ICP refinements, A/B comparisons) want the workflow already built. Articos provides dedicated surfaces per job, plus unlimited-research pricing that scales with frequency.
Yes. Unlimited researches across every client on one $199/mo Pro subscription. White-label reports built in — your logo, your colors, your voice on every deliverable.
Same underlying AI models. Different architecture. Direct ChatGPT prompting generates 142 themes per study at 4.5% precision — 22:1 noise. Articos produces 17 focused themes with hypothesis-blind interviews, stance diversity (Rogers diffusion), cognitive memory (ACT-R), and a six-stage adversarial review pipeline. 7.5× more accurate, p < 0.002.
