Competitive Landscape
- Decision journals: [FactTune](https://www.fact-tune.com/) centers on probabilistic predictions and later calibration; the App Store also contains multiple Calibrate/Decision Journal products.
- Decision coaching: [Resolve](https://resolvewith.me/) uses AI to expand options, challenge biases, and run 30/60/90-day reviews; [Jury](https://www.askjury.app/) uses multiple AI personas to provide scored opinions.
- Higher-end decision intelligence: [Reflect OS](https://www.reflect-os.com/) publicly targets executives and investment teams and displays individual and team subscription pricing; [RISELENS](https://riselens.com/) emphasizes evidence traceability, scenarios, and team decisions.
- AI-output validation: [Taplid](https://taplid.com/) and adjacent products compare AI output with evidence, policies, or structured rules and return review decisions or trust scores.
- **SERP ownership (observed, not rank-tested):** Candidate queries already return brand sites, app stores, editorial pages, and direct or adjacent tools. We have not recorded localized incognito Top 3/Top 10 positions, so detailed ownership remains unverified.
- **Entry wedge:** Existing products usually ask AI to help decide, validate AI output, or log ordinary decisions. This product measures how AI advice changes human judgment: freeze the baseline, reveal or paste advice, then record the outcome. That behavioral-data wedge is understandable, local-first, and does not ask one AI to grade another.

Why Build This
- Target users are knowledge workers who use ChatGPT, Claude, Gemini, or Copilot for product, operations, research, hiring, content, and technical decisions. Team leads, consultants, analysts, and AI trainers are the most plausible payers.
- The real problem is not merely knowing that AI can be wrong. Users cannot see when confident language moved them from “I don’t know” to a wrong answer, or when confidence rose without new evidence.
- Free chatbots do not reliably preserve a pre-advice baseline or provide cross-decision influence delta, Brier scores, reversal rates, and outcome reviews.

How to Build (8h MVP)
Next.js + Tailwind CSS
8h MVP Checklist
- 1.Define schemas for decision, baseline, AI advice, post-AI judgment, outcome, and metrics; add calculation tests.
- 2.Build judgment creation, baseline locking, and the `I don't know` path.
- 3.Build AI advice, post-AI judgment, and Influence Report.
- 4.Build outcome review, Brier score, calibration buckets, and Dashboard.
- 5.Add local persistence, delete controls, and JSON/CSV/Markdown export.
- 6.Add Home, Method, About, FAQ, Privacy, and 10–15 practice scenarios.
- 7.Add Paid Pilot, Payment Link/priced lead, and privacy-safe analytics events.
- 8.Complete mobile, accessibility, SEO, unit-test, and production-build verification.

Risks
- △**Acquisition:** no measured search volume and a crowded head-term SERP. Research content must prove it can convert people into journal users.
- △**Retention:** calibration needs real outcomes and some decisions resolve slowly. Include 1–14 day sample decisions with observable outcomes.
- △**Payment:** individuals may only want a free local tool. Test a small-team paid pilot before assuming consumer subscriptions.
- △**Competition:** decision journals, AI coaches, and AI verifiers already exist. `Answer-first + AI influence delta` must be obvious in the hero and demo.
- △**Privacy:** decision content is sensitive. Default to local storage, provide delete/export controls, and warn against entering professional secrets or high-risk personal information.
- △**Scientific claims:** do not generalize one experiment into “AI always makes people worse,” and do not claim the product improves accuracy without product-specific evidence.
- △**Portfolio:** it is still a tool site, but it does not compete for recent checker, coding, or Chrome-extension keywords. Reusable scoring/report components create synergy rather than internal competition.
