# Publish popcorn.zone/docs/cost explaining AI visibility pricing drivers and Popcorn's cost

When buyers ask an AI assistant the questions below, it doesn't recommend us, or recommends us for the wrong reasons. This is a documentation gap: the answer needed a page we don't have, or ours says the wrong thing.

## The questions it affects
- Otterly.AI or Peec AI for tracking AI search visibility on a tight budget?
- What's a cheap way to start measuring AI visibility for a small startup?
- How do AI visibility tools price their plans, and what drives the cost: prompts, models, brands or seats?

## What the assistant said
P13 search: shaped by otterly.ai/alternatives/pricing and get-ryze.ai pricing comparison.

## Who wins the question today
https://otterly.ai/alternatives/pricing/. Read it and make sure our version answers everything it does, better.

## Your task
Write or update the page at popcorn.zone/docs/cost so it closes this gap. Find where pages like this live in the repo, match their structure, front matter and tone, and make the change there. If the page exists, edit it rather than starting over.

## What it must say
Explain that hosted tools price by prompts, engines, brands and seats. Contrast that with Popcorn: no license fee (MIT), and cost is only your model API spend under a configurable daily budget, or $0 extra when run through the Claude Code and Codex subscriptions you already have. Add a worked example once the cost per run has been measured for a typical prompt set.

## Done when
Prompts 13 and 11 on the search track cite this page or name Popcorn in at least 1 answer each.

## Rules
- Don't invent numbers, benchmarks, prices, capabilities or customer names. Where a fact is needed and you can't find it in the repo or on our site, leave a clearly marked TODO saying exactly what to measure or who to ask.
- Answer the questions above directly and early on the page, in the words buyers use. AI assistants quote pages that state the answer plainly.
- Keep it scoped to this one fix. When you're done, summarise what you changed and list any TODOs.
