How we verify

Evidence: Article or interviewA newsletter, journalist or interview account of what happened.

Context: In a comparison test: from a head-to-head chatbot review, not a standalone agent test.

Outcome

Lisa Peyton gave Gemini, ChatGPT and Perplexity Deep Research the same prompt for a report on generative AI in B2B visual marketing; Gemini's roughly 9,500-word report was rated highly accurate with 95 distinct citations, though she found it more theoretical than practical, with fewer pricing details and implementation examples than ChatGPT's.

This is the source's own number. We haven't measured it.

Prompt Recreated prompt

The source didn't share its exact prompt, so we wrote this from what it describes.

Let's work this out together. I'll tell you what I'm after; help me sharpen the goal before you dive in, and check in with me before anything you can't undo.

Goal: Help me produce a well-sourced industry report on a marketing trend that I can use for strategy and content.

Questions to explore first: What trend and audience, how long should it be, and is this for strategy, a white paper or blog content?

What I need from you:
- The topic and industry
- Who will read it
- Length and format you want

Rules:
- Suggest 2–3 angles (market overview, how-to playbook, tool comparison) and recommend one.
- Cite every statistic with a link and date; prefer research firms and trade publications.
- Include real company examples and tool pricing, not just theory.
- Add an implementation section: first steps, costs and how to measure results.
- Export to a Google Doc.

Output: A cited report with an executive summary, examples and an action plan, plus next steps.

If any of this is unclear, tell me what you have and I'll help fill the gaps.

You'll know it worked when: the stats check out when you open the sources and the action plan is specific enough to start this quarter.
