This review is part of a larger series of LinkedIn newsletters titled The Human Side of AI: Cutting through the AI noise to show you how AI can be a powerful tool for your creativity, efficiency, and strategy.
SYMAR, the platform formerly known as OpinioAI, lets you create synthetic respondents and run research against them without recruiting a single human. When I first covered it, that meant a flat $99 a month. Today it’s credit-metered, starting at €99 / $119 a month (more on that below).
What’s new since we last reviewed this tool in 2024: OpinioAI has since rebranded to SYMAR (symar.ai). Most of what were filed under “future plans” back then, including synth-driven focus groups and multi-synth interviews, has shipped. The pricing model changed too, enough has moved to warrant a real refresh.
You still begin with the persona builder, where you define the demographics and traits relevant to your “synth”: educational level, income, interests, personality, needs and wants, primary motivation, and more. The notable addition since my first review is that personas now layer OCEAN (Big Five) personality traits over multiple foundational LLMs. A price-sensitive parent in Berlin behaves differently from a tech-forward student in San Francisco.
You can still choose which AI model backs your persona work, and you can still fine-tune custom models by uploading your own data. The data-formatting step remains. It’s not quite drag-and-drop a text file, though it’s not a heavy lift either. New here is “Synthetic Memory,” which lets you inject real data such as past surveys or CRM records into a persona, grounding its responses in actual behavior instead of pure model output. For anyone worried about hallucinated synthetics, that is a useful guardrail.
The biggest change is that the roadmap described last time is now the product:
- Synthetic Focus Groups. An AI moderator runs a virtual room of multiple personas, guides the discussion, and hands you a full transcript and analysis.
- Synthetic 1-on-1 Interviews. The multi-synth interview capability I said was coming is now live.
- Synthetic Surveys. Define a segment, ask up to roughly 30 questions, and run insights research at scale.
- Multi-modal Creative Evaluation. Test text, images, and video through the lens of your personas.
- Document and dataset analysis. Still here, and still one of the more useful everyday features.
SYMAR still points to a growing list of academic studies on the role of synthetic respondents in market research. Give them credit for one thing: the marketing has caught up to reality. My original gripe was with the claim that you could get buyer and ICP insights “without… custom research.” SYMAR now says the opposite. Its stated position is that synthetics can’t replace humans and work best as an augmentation of traditional research. That is what I argued in 2024, and now the vendor says it too. Any researcher worth their salt still wants real human responses in the mix.
One caveat that didn’t exist last time: the field has gotten crowded. In 2024, an affordable self-serve synthetic platform was a rarity. Today SYMAR competes with Synthetic Users, Minds, Aaru, Evidenza, Perspective AI, Lakmoos, the heavily funded Simile, and Qualtrics baking synthetic respondents straight into its survey platform. Several of those rivals publish accuracy benchmarks. SYMAR still leans on a methodology narrative rather than prominent published numbers, which is the one place I’d most like to see it catch up.
Here are my updated ratings from a market research perspective.
| Dimension | Rating | Rationale |
|---|---|---|
| Usability | 3.5 / 5 | The rebrand brought a cleaner site, dedicated feature pages, and real documentation. The old “Windows vs. Mac” gap has narrowed, though I’d want a fresh hands-on pass before calling it polished. |
| Power | 4.5 / 5 | The upgrade I predicted happened. Focus groups, interviews, surveys at scale, multi-modal evaluation, and Synthetic Memory make this a far more capable platform than the one I first reviewed. |
| Flexibility | 4.5 / 5 | More ways to tune the work: inject your own survey or CRM data, build custom models, choose among foundational LLMs, and dial in OCEAN traits. |
| Cost | 4 / 5 | Still cheap next to custom research, but the clean flat $99 is gone. Entry is now €99 / $119 a month, credit-metered and capped at 400 credits, with the next tier starting around €199 / $239. |
| AI Washing | Low | The “world’s leading” positioning and human-parity language lean harder on marketing than the published evidence supports. Real capability underneath, but a notch above the “None” I gave last time. |
The verdict: SYMAR is worth a look, with eyes open. For early message testing and a rough read on a segment before you spend real money in the field, it saves time and budget. Just don’t treat it as a stand-in for your actual buyers. The strongest studies use synthetics to sharpen the questions, then put those questions to real people. Human plus AI is the operating model here, same as everywhere else in this series.
