What is cognitive bias detection?

The system identifies which psychological triggers your idea activates, like anchoring, social proof, scarcity, loss aversion, and authority, so you can intentionally dial up or avoid them.

How many replicas can test my idea?

Between 5 and 300 replicas per test. More replicas give you finer demographic segmentation and more diverse feedback.

Can I test unpublished work?

Yes. All ideas are evaluated in isolation. Replicas never see them outside the test. Your unpublished work stays private.

The Wrong Direction Multiplies Through Everything That Follows

Three directions, two visuals, four headlines. Your team votes, instinct wins, and the brief goes out. Every subsequent decision builds on that first call. Getting it wrong at the start does not cost one campaign. It costs every campaign after it.

A/B testing requires live traffic or a published piece. If you do not have either, you are paying to learn what does not work. Idea Testing works before a single impression has run.

Internal creative review is taste. The only opinion that actually predicts conversion is your audience's. The people around you are invested in the work and cannot tell you it does not land.

Once you brief a direction, every subsequent decision builds on it. Getting the direction wrong at the start multiplies through the entire campaign or content calendar.

From Concept to Confidence

Submit your idea

Paste a hook, headline, or caption. Describe a visual or thumbnail. Outline a video script or audio intro. TikTok hooks, YouTube thumbnails, Instagram captions, ad copy, product concepts — any format is supported.

Define your audience

Match replica groups to your actual target market. Set the platform (TikTok, YouTube, Instagram, Google, LinkedIn, and more) and the goal: engagement, clicks, brand awareness, or conversions. Platform context shapes every score.

Cognitive Bias Detection

Lists every psychological trigger your idea is activating: scarcity, social proof, loss aversion, authority, anchoring. Knowing which levers you are pulling, and which you meant to pull, is how intentional creative gets built.

All formats

Any Content Type

Text, image, video, and audio across every major platform. TikTok hooks, YouTube thumbnails, Instagram captions, Google ad copy, LinkedIn posts, podcast scripts. If your audience encounters it, test it first.

Your buyers

Test against your real audience

Import your subscriber list or customer base and score your ideas against their replicas. Performance scores reflect the people who actually buy from you, not a generic proxy.

Who Tests Ideas Before Launching

Any team that turns creative decisions into spend, content, or products and needs to get the direction right before committing.

Performance Marketing

Test five headline variants before briefing copy. Hand the copywriter the winning direction backed by audience data, not a brief based on a hunch that gets revised four times in review.

Creators & Influencers

Test the hook, thumbnail, and caption before you post. Which opening line stops the scroll on TikTok? Which YouTube thumbnail drives the click? Which Instagram caption gets the save? Test variants against your actual target audience before the algorithm locks in your reach.

Brand & Creative Teams

Validate concepts before the production shoot. Know which direction the audience responds to before committing production cost to the wrong one.

Agencies

The client says 'we are not sure about direction B.' You bring audience data showing which direction wins and why. The creative debate ends the moment the evidence enters the room.
