Case Study Builder

Turns raw client-win details into three ready-to-use case study formats for proposals, social posts, and your website.

Marketing & SEOBeginner★ 429⑂ 100AI score 9/10Last updated: Mar 19, 2026

What it does

  • Collects 8 required intake fields: client profile, before state, actions taken, results, timeline, quote, naming permission, and intended use.
  • Blocks drafting until you supply at least one concrete number, offering prompts (revenue change, hours saved, lead volume) if you only say "results were good."
  • Classifies outcome strength into Tiers 1–4 so the wording never overstates a soft or proxy result.
  • Reframes everything with the "client is the hero, you are the guide" principle.
  • Produces a two-liner for proposals, a 150–250 word story for LinkedIn/sales calls, and a full markdown case study for your site — plus a required self-critique checklist and a distribution plan.
  • Three modes: quick, standard (default), deep.

Who it's for

  • Freelancers, consultants, and agency owners who need credible proof in proposals.
  • B2B marketers and solo founders building a portfolio or sales enablement library.
  • Anyone who finished great work but never documented it.

Example uses

  1. "Built a content system for a Series B SaaS founder; 0 to 3 inbound leads/week in 6 weeks" → get a proposal two-liner and a LinkedIn story.
  2. Client won't allow naming → generate an anonymized full case study ("a Series B SaaS company").
  3. Vague outcome → the skill pushes back for a metric like "cut from 10 hours to 2 hours/week" before writing anything.
