Pain: LearnHarness is a desktop app that needs your own provider API keys; most students cannot or will not set that up, and it is English-first. Monetization: Freemium with monthly study-minute plans (managed model costs); school/cursinho self-serve seats (hypothesis). Build: ~2–3 agent-weeks (host the AGPL app, managed keys, PT/ES prompts, billing); stack: Fork of LearnHarness (AGPL-3.0, source published) on Vercel; Supabase; OpenRouter managed keys with per-user caps; Stripe/Pix. GTM: SEO/GEO per topic ("entender derivada passo a passo"), shareable knowledge-graph images, student Discord/WhatsApp groups.

Por que esta nota

Por que a nota foi menor: The maintainer is likely to launch the same hosted, managed-key version.

Barreira de entradaHipótese

Weak: AGPL means competitors can copy. Local-language curriculum maps could help. Status: Hypothesis.

## Customer and pain
Target customer: University and pre-university students in Brazil and LatAm (ENEM, vestibular, engineering calculus) and self-learners who cannot set up API keys.
Pain: LearnHarness is a desktop app that needs your own provider API keys; most students cannot or will not set that up, and it is English-first.

## Market and competitors
TAM: Not sized this run — Scope: Global excl. China. Method: No third-party report fetched. (Basis: n/a)
SAM: Not sized — Scope: Target languages/markets above. Method: HBV assumption. (Basis: Hypothesis)
SOM: ~$6K–$48K ARR (hypothesis) — Scope: Month-6 run-rate. Method: From revenue hypothesis ×12. (Basis: Hypothesis)
Competitors: ChatGPT Study Mode, Gemini Guided Learning, Khanmigo, NotebookLM, Brainly, Me Salva! (BR), Descomplica (BR).
Geography: Brazil, Mexico, Colombia, Argentina; global English later

## Business model
Monetization: Freemium with monthly study-minute plans (managed model costs); school/cursinho self-serve seats (hypothesis).
Revenue hypothesis (monthly): ~$500–$4K/month at month 6 (HYPOTHESIS).

## Build and go-to-market
Build effort (agent-weeks): ~2–3 agent-weeks (host the AGPL app, managed keys, PT/ES prompts, billing)
Time to first revenue: ~4–6 weeks
Tech stack: Fork of LearnHarness (AGPL-3.0, source published) on Vercel; Supabase; OpenRouter managed keys with per-user caps; Stripe/Pix
GTM channels: SEO/GEO per topic ("entender derivada passo a passo"), shareable knowledge-graph images, student Discord/WhatsApp groups

## Risks and next step
Main risk: The maintainer is likely to launch the same hosted, managed-key version.
Next validation action: Do not build now. Watch whether stars keep accelerating for 7 more days and whether the maintainer launches hosting.
