Título provisório: Personal Inflation Mirror: your real inflation from forwarded receipts (working name)

Resumo

BriefingHipótese

New idea. Existence check: Checked 22 Oct 2026: Argentina's INDEC offers a personal CPI calculator based on spending categories (not receipts); Recibbi tracks repeated purchases from receipt photos vs CPI (claims promotional); Nottei (Brazil) calculates personal inflation from receipts but is still in family testing; El Changuito (Argentina) tracks prices.…

DescriçãoHipótese

Forward supermarket receipts or Pix/ticket photos on WhatsApp and get "your inflation vs the official one" each month — a shareable card plus a city leaderboard of what really got pricier — for Argentina, Turkey, Nigeria, Brazil and Egypt. Who: Aplicação global: households in high-inflation countries (Argentina, Turkey, Nigeria, Egypt) who distrust official CPI.…

Versão LatAm: Argentina and Brazil first (Spanish/Portuguese), then Colombia and Mexico. Pain: Official inflation does not match a family's own basket; people feel poorer than the number says but cannot prove it or see which items drove it. Monetization: Free for users; self-serve sponsor slots (supermarkets, cashback apps, fintechs) priced with traffic; paid monthly "price newsletter" per city (hypothesis ~US$2–$3); anonymized price-index licensing later. Build: 1–2 agent-weeks (WhatsApp receipt intake, OCR/LLM line-item parsing, basket matching to CPI categories, share cards, city pages); stack: Next.js on Vercel; WhatsApp Cloud API; OCR + LLM parsing; Postgres; OG image cards. GTM: Monthly share cards on CPI release day; SEO/GEO for "mi inflación real", "inflação pessoal"; press-friendly city leaderboards; faceless.

Cliente-alvo

Aplicação global: households in high-inflation countries (Argentina, Turkey, Nigeria, Egypt) who distrust official CPI. Versão LatAm: Argentina and Brazil first (Spanish/Portuguese), then Colombia and Mexico.

Dor

Official inflation does not match a family's own basket; people feel poorer than the number says but cannot prove it or see which items drove it.

Por que esta nota

Por que a nota foi menor: Weak current X signal (69 posts/7d) and receipt-forwarding friction; Nottei or INDEC could cover the angle.

Barreira de entradaHipótese

Receipt-level price dataset: Line-item prices by city compound into a unique index. Monthly CPI-day cards create recurring virality. Status: Hypothesis.

Demanda na webVerificado

Topic X talk is small (69 posts/7d, Verified X API) — demand shows mostly through government action (INDEC launched a personal inflation calculator, per Clarín and BAE Negocios) and several small receipt-based tools.

Jobs to be done

When official inflation does not match my bills, I want to see my own inflation from my receipts, so I can prove it and share it.

HXC

Martín, 36, Córdoba (illustrative) · Shops weekly at the same supermarket; argues about INDEC numbers with family. Buying signal: Would forward receipts and share his monthly card on CPI day.

Canais de GTM

Monthly share cards on CPI release day; SEO/GEO for "mi inflación real", "inflação pessoal"; press-friendly city leaderboards; faceless

Riscos

Principal risco

Weak current X signal (69 posts/7d) and receipt-forwarding friction; Nottei or INDEC could cover the angle.

Todos os riscos

Value: Attention — Small X signal | Usability: Attention — Receipt forwarding friction | Feasibility: Supported — OCR/LLM parsing feasible | Business Viability: High — Low monetization

Próximo passo de validação

Launch in Argentina for the next INDEC CPI release; kill if fewer than 2,000 receipts forwarded in the first 30 days.

Forward supermarket receipts or Pix/ticket photos on WhatsApp and get "your inflation vs the official one" each month — a shareable card plus a city leaderboard of what really got pricier — for Argentina, Turkey, Nigeria, Brazil and Egypt.
