Help knowledge workers preserve independent judgment before seeing AI advice, measure how AI changes their answers and confidence
At a glance
- 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.
Differentiation Opportunity
- Answer first: the AI-advice step stays unavailable until the baseline answer, confidence, and rationale are frozen.
| Keyword | Volume/mo | KD | CPC | Read |
|---|---|---|---|---|
| ★ brier score | 1,900 | — | — | The strongest real signal in the family — and codex didn't name it: 1,900/mo, +85% yearly (1,300 → 2,400), almost certainly riding the LLM-calibration research wave. The head term's SERP is an academic wall (NIH featured snippet, Wikipedia, scikit-learn), but a forecasting SaaS (cultivatelabs) holds #6 — commercial results can rank. The wedge is an interactive calculator page, not the head term. |
| ai decision making tool | 30 | 16 | $8.35 | Codex's pick, measured at 30/mo (-60% yearly). The difference from every prior week: codex PRE-DECLARED this as an unverified hypothesis and wrote 'the launch cannot depend on ranking for this word'. Measurement confirms the caution instead of puncturing a claim — the new evidence-grading rules working as designed. |
| decision log (+ template) | 480 | 1 | $22.64 | The money words: `decision log` 480/mo at $22.64 CPC, `decision log template` 320/mo at KD 1 ($11.72). But the SERP is a PM-SaaS content wall (monday, Miro, Aha!, Plane, ProjectManager all rank via template pages) and the intent is ENTERPRISE project decision tracking — not personal decision quality. Usable only through a 'personal decision log' bridge page; don't mistake this for product-fit demand. |
| decision journal | 170 | 25 | $0.50 | The closest true-fit word with any volume — the Farnam Street legacy term for exactly this practice. 170/mo, KD 25, declining -35%. Small, but the searcher's intent matches the product one-to-one. The honest homepage word. |
| ai fact checker | 590 | 10 | $4.72 | The adjacent trap, measured for the record: 590/mo at KD 10 looks inviting, but codex itself flagged the mismatch — this product deliberately does NOT verify facts. Chasing this word would attract users the product is designed to disappoint. Stay out. |
| product vocabulary (verify ai answers / should i trust chatgpt / ai second opinion) | 50 | — | — | The fifth 'vocabulary not formed yet' case in eight days (after workplace-surveillance, podcast-cleanup, chrome-AI, and roblox's planner words): every phrase describing what this product actually does is absent from the database, plus `confidence calibration` at 50/mo. The category doesn't exist in search — which is precisely why codex's 3-5 day paid-pilot plan (validate demand off-search first) is the right-sized bet. |

Three key findings: (1) both lanes with volume have a wall — brier is academic, decision log is PM-SaaS content marketing — but neither is unclimbable (cultivatelabs and the 'Decision log app' related search are two seams); (2) no result anywhere serves 'personal AI-advice calibration' — that's either a blue ocean or a nonexistent market, and that question is exactly what the paid pilot answers; SEO data cannot; (3) decision journal's Farnam Street legacy intent is the only one-to-one entry, at just 170/mo.
Verdict: measurement CONFIRMS codex's 🟡 — the first report in this archive where DECISION and measurement pointed the same way from the start. The new evidence-grading rules worked.
verify ai answers, should i trust chatgpt, ai second opinion — all absent from the database.
