Proofsource is an AI visibility platform that puts approved buyer questions to AI answer engines, stores every answer with its sources and a screenshot, and ranks the fixes behind each lost answer. Pricing is per brand and per question.

| Fact | Value |

| Website | https://proofsource.co |
| Price | from $9/month billed monthly, $7.50/month billed annually |
| Free trial | Partly |

Two-day trial: 2 scans (today and tomorrow), 25 questions on all four standard-panel engines, 200 answers, plus 100 trial credits for drafts, chat and agents. No card, one trial per company domain; scanning then pauses and stored answers remain.

## What it does

**Monitors AI answers** · Yes — Core of the product: approved buyer questions are asked repeatedly and each answer is stored, scored for mention rate, share of voice and position per engine.

> — https://proofsource.co/ · Hero paragraph under 'Find where AI leaves you out. And fix it.'

**Optimises your content** · Yes — It ranks gaps behind lost answers by likely gain against effort, names the page or source to change, and runs technical, SEO and AI-readiness checks on existing pages.

## Answer engines

**ChatGPT** · Yes — ChatGPT is on the standard panel for the trial and the price card, read as a logged-out visitor on chatgpt.com with the OpenAI API as a fallback.

> As a logged-out visitor on chatgpt.com, read through a data provider. If that read fails, the OpenAI API answers instead, and the stored answer records which one it was.
