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.

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'll give you:
- The topic and industry
- Who will read it
- Length and format I 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 anything here is unclear or missing, ask me instead of guessing.

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

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: Produce a well-sourced industry report on a marketing trend.

First: restate the goal in one sentence, suggest 2–3 ways to approach it, recommend one, and wait for my pick.

Inputs (fill in or confirm):
- Topic
- Reader
- Length and format
- Budget for tools mentioned

Rules:
- Suggest angles and recommend one.
- Cite every statistic.
- Include examples and pricing.
- Add an implementation section.
- Separate theory from practice: include at least 3 real company examples with sources.
- Add a section on measuring results (metrics, baselines).
- Flag statistics older than two years.
- Write an executive summary under 200 words.
- Note where sources disagree and why.
- Include a pricing table for named tools with dates.
- Add a step-by-step implementation plan for a small team.
- Keep citations next to each claim, not only at the end.
- Keep the report to the length and format I set.
- Give a list of further reading.

If you get stuck: If a statistic can't be sourced, cut it. If a login, CAPTCHA or two-step code appears, stop and ask me to handle it; never guess or store passwords.

Verify before you finish: Open each source.

Output: Cited report, plus next steps.

Done when: stats check out and the plan is actionable.
