An MIT repo of prompts and scripts that lets the AI assistant you already use turn a messy folder of receipts, PDFs and statements into a tax-ready summary, with country packs (Brazil IRPF first).

POP 5.6 slot: a NEW repo HBV would launch on GitHub (cesarx2) to go viral and earn from derivatives. Template proof: cleanyourtv hit 14,989 stars in 4 days (Verified, GitHub API) by shipping a prompt that any coding assistant follows to fix a universal annoyance; the 22-day PhotoCraft family reached 70K stars (Verified).…

Hook: 'AI sorted my tax paperwork in 10 minutes, offline, with no upload'. Universal audience (every adult files something), country packs invite contributors, tax season gives a calendar spike. Derivatives: hosted version, per-country SEO pages, paid packs. Existing open-source repos were not checked in detail this run (limited verification).

描述

Repo concept (GitHub cesarx2/taxfolder): PROMPT.md + CLI that scans a local folder, extracts amounts/dates/payees from PDFs and images with a local or API model, classifies by country pack (BR IRPF deductions: health, education, income reports; US schedule items; UK self-assessment), and outputs a CSV/Markdown checklist with missing-document warnings.…

阅读其余部分

Local-first, no upload by default. Not tax advice. Global Application: any country via contributor-written packs. LatAm Version: Brazil IRPF pack first (informe de rendimentos, despesas médicas), Mexico SAT pack second; PT-BR/ES README.

目标客户

Self-filers and freelancers in Brazil, Mexico and English markets who already use an AI assistant

痛点

Hunting documents for tax season; privacy concerns about uploads

为何是这个分数

分数较低的原因： Virality and liability

市场与竞争对手

TAM假设估算

$5B+ (Hypothesis) — Consumer tax-prep tooling spend. Method: Hypothesis. Sources: Hark estimate (Hypothesis).

SAM假设估算

$60M (Hypothesis) — Brazil/Mexico/Spanish and English self-filers using AI helpers. Method: ~20M x 2% x $15/year ≈ $6M near term; $60M ceiling. Sources: Hark estimate (Hypothesis).

SOM假设估算

$40K ARR (Hypothesis) — 12 months after traction. Method: ~1,500 hosted users x ~$25/year; depends on repo stars. Sources: Hark estimate (Hypothesis).

竞争对手

Commercial AI tax apps, spreadsheets, accountants, small unverified repos

商业模式

变现方式

Open-core: MIT repo; hosted tier, paid packs, sponsor slots, SEO pages

收入假设（每月）假设

Base ~$1K/month, conservative ~$0/month at 12 months (Hypothesis).

待完成的任务

When tax season means hunting for documents, I want a checklist built from my own folder, so I can file on time with confidence.

HXC

Fernanda · 38 · Porto Alegre: Keeps PDFs in folders, files IRPF every March. Frustration & buying signal: Dreads the paperwork hunt; would use a free local tool and pay for a hosted one.

构建与 GTM

技术栈

Cursor + Vercel + GitHub cesarx2 (one repo); Supabase; Stripe

GTM 渠道

HN/Reddit/dev.to launch with faceless assets, contributor PRs, per-country SEO; no founder on camera, no paid ads

风险

主要风险

Virality and liability

全部风险

Value Risk: Attention — Hook may not go viral. Next: Test README on HN/Reddit. | Usability Risk: Attention — Non-technical users need an assistant or hosted version. Next: Hosted checkup later. | Feasibility Risk: Attention — Accuracy per country. Next: Start with BR IRPF only. | Viability Risk: Elevated — Tax-advice liability. Next: Strict 'organiser, not advice' copy and legal review.

下一步验证

Prototype repo + README hook; enumerate existing repos; BR pack
