4.2 ShipScore / 10

Weakest is need — no paying demand; entry near zero, weekend-cloneable feature.

Condition: Only proceed if you find 20+ teams already paying for capitalization/style enforcement inside a regulated document workflow (e.g., legal or pharma copy compliance) — not generic text checking.

Scale

What the five commandments measure

C — Control	Do you own the customer, or does a gatekeeper stand between you and revenue?
E — Entry	How hard is this to copy once it works? A rival's existence isn't the question — the durability of their advantage is.
N — Need	Is demand proven with money rather than vibes?
T — Time	Can income detach from your hours, or did you buy yourself a job?
S — Scale	How far does it reach without linear cost?

Scored on the evidence below, against CENTS as we've adapted it plus a Buffett-style moat reading of every rival — the same referee for every idea, including the ones we generate ourselves. The verdict follows the arithmetic: we never relabel a score to make it read better, and the weakest commandment is always named. The exact rubric stays in-house so the scale can't be written for.

Part II — The Evidence the receipts, good and bad

03 — Rival scan — corpus tracks 5 similar, 2 stalled under $2k MRR

Kibu	verified MRR $234k · CENTS 7.8 (trustmrr)
ClearPolicy	verified MRR $0k (x)
AI Fact Checker App	verified MRR $0k (x)
Flightview - Flight Tracker	6338 reviews · 3.7★ (appstore-us)
Letterly	353 reviews · CENTS 5.8 (appsumo)

Grammarly / built-in style checkers (general market knowledge) — Capitalization and formatting rules are already free, bundled, and better trained in every writing tool and word processor.
Kibu ($234k MRR, CENTS 7.8) — Shows the corpus's money sits in a substantive product, not a one-rule validator; it sets the bar you can't reach with a formatting check.
Dili ($21.7M Series A) — Funded compliance-automation capital can absorb trivial validation features as a checkbox inside a broader diligence platform.

04 — Demand evidence

Evidence is thin to absent: 2 of 5 tracked similar products with verified revenue stall under $2k MRR.
Two closest analogues — ClearPolicy and AI Fact Checker App — both sit at $0k verified MRR.
Zero Reddit demand signals found for these keywords, meaning no visible complaint volume or unmet-need chatter.
Money in adjacent space is in heavyweight compliance workflows (real estate txn mgmt asking $1.7M at 2.4× profit), not text validators.

05 — Risks

Capitalization checking is a feature, not a product — bundled free by Word, Docs, and Grammarly.
Self-described 'test idea' with no defined buyer, industry, or compliance regime to anchor pricing.
Price ceiling is a few dollars/month, so CAC will exceed LTV on paid channels.
Two directly comparable products already validated $0 revenue in this exact lane.

06 — Kill switches — what kills this with one decision

LLM API providers (OpenAI/Anthropic) — A single model-quality bump makes 'check my capitalization' a free prompt, erasing the product overnight.
Microsoft/Google editor roadmap — One shipped style-enforcement setting inside Word or Docs removes the entire reason to install a third-party checker.
Chrome Web Store / app-store distribution — If distributed as an extension, one policy or ranking change removes your only discovery channel.

Part III — The Plan if you insist on proceeding

07 — What this scan can't tell you

Cannot tell which vertical's style guide (AP, legal citation, pharma labeling) you'd target — that choice decides everything.
No data on whether any compliance regime actually mandates capitalization checks with audit trails.
Cannot assess the founder's existing distribution or embedded-API partnerships that might change unit economics.

Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-08-02.

08 — The wedge & the next step

Abandon generic capitalization; embed as an auditable style-and-format gate inside one regulated document pipeline (pharma promo review or legal filings) where a formatting error carries real financial penalty.

Cheapest next step: Spend two days cold-emailing 25 medical/legal review managers asking what they currently pay for document style enforcement; if fewer than three name a line item, drop it.

Not quite it? Spin the model

Business-model variations of this idea, engineered to beat 4.2 — different vertical, audience, model, or wedge. Same harsh scale. Pro feature.
