Proofsource vs Peec AI
Pick Peec AI if you want to choose your own 3 engines per plan from a list that includes Gemini, Microsoft Copilot and Naver AI, buy self-serve, and dig deep into sources and citations. Pick Proofsource if you need ChatGPT, Perplexity, Claude and Google AI Overviews together in the default panel, a 95% interval on every figure, and a draft fix for each gap. On Peec AI's standard plans, Perplexity is an extra model and Claude appears on Enterprise.

Peec AI sells three self-serve monthly tiers by prompt count, with 15% off annual billing; Proofsource starts with a free trial, then one self-serve price card per brand. Peec AI's prices assume 3 models; each additional model is an add-on priced by plan. Proofsource prices each engine per question, with four on by default.
Does Peec AI charge extra for additional AI platforms?
Yes. Each Peec AI plan includes 3 models, and its pricing page lists each additional model, Perplexity included, as a paid add-on. It says countries and languages cost nothing extra; pricing follows prompts and models.
What are the key limitations of Peec AI in 2026?
From its own pricing page: 3 models per standard plan, Claude on Enterprise, a free trial whose length it does not state, and no published confidence interval on its figures. API access is listed on Enterprise.
Where Proofsource shines: 4 things it is built to do.
Each one is a mechanism: what runs, how often, and what would catch us out if it were not true.
The free trial is the real report.
The free trial asks 25 buyer questions on ChatGPT, Perplexity, Claude and Google AI Overviews, 2 scans a day apart, and hands back what a subscriber reads: which questions name you on which engine, who is named instead, and the pages each engine cited. No card, no call. One per company domain.
Every number arrives with the interval it was measured at.
Ask an engine the same question twice and you can get two answers, so one read is a draw, not a fact. We publish a 95% Wilson interval on every percentage and hold alerts until a change clears it. A tool that treats a single run as a finding will sell you progress on a day you did nothing.[2]
Four engines from the free trial, 4 on the price card.
ChatGPT, Perplexity, Claude and Google AI Overviews run side by side from the free trial upward, each priced per question on paid plans; Google AI Mode, Gemini, Microsoft Copilot, Grok, DeepSeek and Meta AI are enabled on a call. The questions are re-asked on their own on the cadence you pick: daily or weekly. The full history leaves as CSV or JSON over any date range, or through the REST API, so the record is yours.
Each gap names the page that beat you, then drafts the answer.
A gap carries the sources the engines cited instead of you. Then a draft built on what those pages have and yours does not, held for a human to approve, because nothing should publish itself in your name.

Where do the Peec AI facts on this page come from?
From Peec AI's own public pages, linked in the Sources list with the date we read them. We have not run Peec AI on a domain of our own, so no measured number on this page is theirs. If a row is out of date, tell us and we will change it.
Where each fact on this page comes from.
- Peec AI pricing, read Oct 5, 2026. Peec AI's own page; no third-party roundup is used as a source.
- Wilson score interval. The interval we put on every visibility percentage. Introduced by E. B. Wilson in 1927 and standard for binomial proportions, because it stays honest at small sample sizes and near 0% or 100% where the naive normal approximation breaks.
- Proofsource sampling: day-over-day change in which brands get named, same question one day apart. Perplexity 27%, ChatGPT 18%, Google AI Overviews 12%, Claude 9%. How we measure.
