Where it fits
You have several creative options. Which ones deserve live-test budget?
Adsynex is the screening step between making variants and paying to test them. It narrows the field. A live test still confirms the winner.
- Create variantsImages and copy

How it works
Four steps from upload to verdict.
Describe the audience
Start from a preset or set age, gender, up to six cities or countries, language and interests.
Upload creatives
Two to ten images, each with the headline, primary text and CTA you plan to run.
Choose a plan and see the cost
Pick Fast or Smart and the number of personas. The cost in credits is shown before you launch.
Read the report and iterate
Ranking with confidence ranges, five criteria per creative, feedback and next steps. One click copies the setup into a new round.
What is a persona?
An AI-generated profile drawn from the audience you set.
Each persona has an age, location, language and interests from your settings, plus its own taste, skepticism and reading habits. Every persona scores every creative independently on five criteria: visual appeal, relevance, message clarity, trust and emotional pull. Scores roll up into a 0–100 composite per creative, with a confidence range.
Skims the imageSees the picture, the headline and the button label.
Reads the headlineAlso reads the first line of your primary text.
Reads everythingTakes in all the copy, including prices and dates.

The report
Know what to launch, what to fix and why.
A score tells you which ad won. The report shows why, in the personas' own words, so the next version is better and not just different.
Line-by-line feedback
See the exact words and image areas that cost you attention.
Personas flag fragments of your headline, primary text and CTA, and mark which parts of the image helped or hurt. Each flag shows how many personas raised it and what they said.
Next steps
A clear call for every element.
Keep, revise, remove or test next for the image, headline, primary text and CTA, with the share of personas behind each call.
Segments
Find the ad that wins overall but loses your core buyers.
Composite score for each creative within every age, gender, location and interest group. Small groups are marked as low confidence.
Predicted vs actual
Check the ranking against your real results.
After launch, upload your Meta Ads export. Adsynex matches it to your creatives and compares its ranking with real ROAS, CPA or CTR.
Share with your client
A report you can put your own name on.
Export a PDF with the sections you choose, with or without Adsynex branding, or share a read-only link protected by a password.
Choose your plan
Two plans. The same full report.
The plan sets how deeply each persona studies your creatives. You can pick a plan for each experiment.
Fast1 credit / evaluation
Quick, affordable screening. Every persona scores your creatives and names what caught them or lost them. Great for comparing distinct concepts.
100 personas × 2 creatives = 200 credits
Smart New8 credits / evaluation
Deep review. Every persona reads your headline, offer and visual closely and explains each reaction. Built for close variants and final pre-launch calls.
100 personas × 2 creatives = 1,600 credits
Checked against real campaigns
We tested the tester on live Facebook ads.
We ran Adsynex on Facebook campaigns that had already spent real budget, then compared its ranking with what Facebook delivered: clicks on the buy button per 1,000 impressions.
Fast plan
5 of 7campaigns: the real winner was in the Adsynex top two (38 concepts in total)
3 of 7campaigns: the Adsynex #1 was the real #1
Smart plan
0.97rank correlation with real results on a 5-concept campaign
Top 2matched the real top two on a second campaign
It is most reliable when your concepts are clearly different, and weaker at separating near-identical designs. Use it to cut weak creatives and build a shortlist, then let a small live test pick between the finalists. When two creatives are too close to call, the report says so.

FAQ
Questions we hear before the first test.
Do personas predict real results?
They predict the ranking more reliably than exact numbers. On live Facebook campaigns, the real winner was in the Adsynex top two in 5 of 7 cases. Every report shows confidence ranges and says when two creatives are a statistical tie. Use Adsynex to build a shortlist, then confirm the winner with a small live test.
Does Adsynex forecast CTR?
No. It scores each creative from 0 to 100 based on persona reactions and ranks them. To see how the ranking held up, upload your Meta Ads results after launch and compare.
Fast or Smart: which plan should I use?
Use Fast to compare clearly different concepts and to screen many variants cheaply. Use Smart for close variants and the final call before launch, when you need each persona to study the copy and visual in depth.
How are credits counted?
Personas × creatives × plan rate. Fast costs 1 credit per evaluation, Smart costs 8. A test with 100 personas and 2 creatives costs 200 credits on Fast and 1,600 on Smart. You see the exact cost before you launch.
What can I test?
Static images in PNG, JPG or WEBP up to 10 MB, 2 to 10 per experiment, each with a headline, primary text and CTA. Video, carousel and animated formats are not supported yet.
How long does an experiment take?
Most experiments finish in under 10 minutes. A small test takes about a minute; very large runs with over a thousand evaluations can take around 15 minutes.
What happens to my creatives and data?
Creatives are stored in the EU (AWS, Frankfurt) for 12 months and then deleted. They are never used to train AI models. Evaluations run on Google Gemini, OpenAI and Anthropic Claude models with no training on your data and zero data retention. To delete your account or creatives sooner, email adsynex.inc@gmail.com.
What if an experiment fails?
If an experiment fails on our side, it is marked as failed, no report is built from partial data, and its credits return to your balance automatically.
Can I share a report with a client?
Yes. Export a PDF with the sections you choose, with or without Adsynex branding, or share a read-only link with an optional password.
Know which ad deserves your budget before you spend it.
Your first experiment is free: 100 personas, 2 creatives, the full report. No card needed.
