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

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
- "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.
- Client won't allow naming → generate an anonymized full case study ("a Series B SaaS company").
- Vague outcome → the skill pushes back for a metric like "cut from 10 hours to 2 hours/week" before writing anything.
