A paste-ready one-pager calibrated to your reader, your voice, and your purpose. Pick the document shape (pitch, sales sheet, executive summary, briefing, internal proposal). Get back the full doc plus the variants you'll send.
Same content, dramatically different documents depending on what the one-pager is for. The tool branches the structure based on which job you pick.
Hook → positioning → proof → ask. For when you want them to take the meeting, make the intro, invest, partner, or hire you.
Benefits → features → proof → contact path. Optimized to be forwarded internally to a buyer or stakeholder.
Bottom line up front → context → key facts → decision frame. Front page of a longer doc.
Situation → key facts → options → recommendation with counter-argument → ask. For stakeholder alignment before a decision.
Proposal → cost → benefit → risk and mitigation → approval path. For pitching up at your own company.
Same inputs, different purpose, structurally different document. Validated across three AI models before launch.
Drop in what you're presenting and who reads it:
The thing: Northwind cost-monitor service for Postgres-heavy AWS stacks What it is: A 90-day done-for-you implementation that cuts AWS bills 40% on average. Audience: Procurement lead at a Series B SaaS company Context: Recently raised, scaling infra, evaluating cost-control vendors Cares about: time-to-value, vendor lock-in, predictable cost Skeptical of: outsourced infra (got burned in 2023), buzzword-heavy pitches Purpose: Pitch What's true: - 14 implementations completed since 2024, average 67 days door-to-door - Customer reference: Beth at Skyline (will take a call) - $180K avg first-year savings on infra - Built by ex-Heroku infra team, 2 named engineers - Fixed-price contract, no T&M scope creep The ask: 30-minute scoping call in the next two weeks.
Plus 1 to 3 short samples of your own writing.

Northwind sits in front of Postgres-heavy AWS stacks and tells you what's about to break the budget before it does. 90-day done-for-you implementation. No T&M scope creep, no quarterly add-ons.
Quick ask: 30-minute scoping call in the next two weeks. If it isn't a fit, you'll know in 15.
A Series B procurement team got burned by an outsourced infra vendor in 2023. That's reasonable, and it's exactly why fixed-price plus a customer reference plus a 90-day window matter here. The shape of the contract is the answer to the trust question.
30-minute call. We come prepared with a back-of-envelope read on your AWS posture (you don't need to share anything before the call; we work with public signal). If it's a fit, we scope. If it isn't, you've got 15 minutes back.

Works in ChatGPT, Claude, or Gemini (Claude is our pick for this one). Full one-pager plus your variants comes back in 30 to 60 seconds.
The tool runs entirely in your browser. Your inputs and writing samples never leave your computer until you paste them into your AI of choice. No Shelf server in the middle. No account, no API key, no data collected. Download once, use forever. Form state saves locally so a tab close doesn't cost you your work.
What it does well. Produces a paste-ready first draft that's structurally correct for the job and calibrated to your reader. The five purpose shapes produce different documents from the same content. The voice match is real on Claude. The what's-missing report catches gaps a buyer would flag.
What it does reasonably well. The variants (elevator, 2-minute, email, LinkedIn DM, Slack) are useful starts but you'll want to read each one cold before sending. AI output is a strong first draft, not a finished document.
What it can't do. Invent your substance. The tool will not fabricate customer references, numbers, or proof points. If your "what's true" inputs are thin, the output will read hollow and the gap report will tell you exactly which sections to strengthen.
How we make it. AI drafts. A human reviews and edits everything before it ships. Built for ChatGPT, Claude, and Gemini. Shipped with a 19-check internal quality rubric. If it doesn't work as described, use the 7-day refund, no questions.
