Prompt volume is the whole argument
Fifteen prompts is a sample small enough that a single competitor publishing one good page can swing your reported visibility. It tells you a direction, not a diagnosis.
MyFast AI runs 100 distinct unbranded buyer questions through all seven engines. That is 700 recorded answers, which is enough to see patterns: which question types you lose, which engines skip you entirely, and which competitor keeps appearing in your place.
What you do after the measurement
Otterly.ai is a rank-tracking style product adapted to AI answers. It watches prompts and reports movement. The action is left entirely to you.
MyFast AI is designed around the action. Every audit produces a plain-English fix plan, and the optional Developer Bundle turns that plan into finished files - llms.txt, schema, answer pages, FAQ pages, sitemap - that a developer publishes once and you own permanently.
Where Otterly.ai fits
If you want the cheapest possible monthly line item to watch a dozen brand-critical prompts, and you have a team already producing AEO content, Otterly.ai is a defensible pick.
If you need to know why AI is not recommending you and want the fix in your hands, the prompt volume and deliverables are why businesses pick MyFast AI instead.
