Summary

BriefingVerifiedHypothesis

Benchmark: GitHub repo wheresryan22/anatomy (https://github.com/wheresryan22/anatomy), MIT license. Verified (GitHub API, 20 Oct 2026): created 8 Oct 2026 10:12 UTC (12 days old), 17,227 stars and 1,310 forks, i.e. ~1,435 stars per day since creation. Stars in the last 7 days: ~8,900 (Hypothesis: OSS Insight event-derived cumulative series, 8,105 on 13 Oct → 17,048 on 20 Oct; the source marks its counts as lower bounds).…

Daily additions are slowing (≈2,900/day on 11–12 Oct, 2,730 on 15 Oct, 743 on 19 Oct; same source). The maintainer hosts a free gallery (33 figures) and a community gallery (54 figures, 27 authors) but no hosted generator, no paid plan and no consumer UX: users must install the skill into Claude Code, Codex or similar and wait from minutes to hours per figure. Existence check: No hosted consumer product on top of Anatomy was found: GitHub search (created since 8 Oct) shows agent ports (Codex, Grok, Cursor, ChatGPT plugin), an MCP server (Muwei-TA/anatomy-mcp, 0 stars), a course-writing skill (course-studio), a Chinese translation, a B-roll player (anatomy.easynote.cc) and single-figure personal sites. Human-made "how things work" libraries already exist: Know.it, Animagraffs, Auto Veteran, AskGif, Vectree and Bartosz Ciechanowski's essays.

Revenue hypothesis: ~$1.5K–$5K/month at month 9 (HYPOTHESIS: 300 figure pages, 150k monthly visits, 4 sponsor slots at $150–$400 + 100 teacher plans at $5 + 20 custom figures at $19).

ious adults who search "how does X work"; first in Portuguese and Spanish, where interactive explainers are scarce, then English. Pain: Explanations of how things work are mostly static diagrams or videos; the interactive ones (Ciechanowski-style) are rare and hand-made. Anatomy can produce them, but only for engineers who run coding agents and can spend hours of agent time per figure. Monetization: Free library pages with labeled sponsor slots priced with traffic (education, hardware and tool brands); teacher plan with embeds, classroom mode and printables; paid custom figures with a queue. No approved price. Build: 1–2 agent-weeks for the site and first 30 figures (Next.js library, i18n, embeds, request queue, Stripe); figure generation runs as background agent jobs; stack: Next.js on Vercel; Anatomy skill (MIT) run by coding agents in background jobs; static SVG/HTML custom elements; Stripe; Plausible. GTM: SEO/GEO pages per "how does X work" query in PT/ES/EN; embeddable figures with a backlink (embed loop); "request a machine" voting queue; faceless clips of figures moving on TikTok and Shorts.

Target customer

Students (12–22), teachers and curious adults who search "how does X work"; first in Portuguese and Spanish, where interactive explainers are scarce, then English.

Pain

Explanations of how things work are mostly static diagrams or videos; the interactive ones (Ciechanowski-style) are rare and hand-made. Anatomy can produce them, but only for engineers who run coding agents and can spend hours of agent time per figure.

Why this score

Why it scored lower: Generation cost and quality: good figures take from minutes to many hours of agent time and the skill admits Claude does not always see visual faults, so the library may grow slowly and need human review; the MIT lice…

MoatHypothesis

Library depth + PT/ES SEO + embeds: The moat is the number of reviewed figures ranking in Portuguese and Spanish search and AI answers. Embeds on school sites and blogs create backlinks that compound rankings. Status: Hypothesis.

A broad "/anatomy" X query returned 28,428 posts but is dominated by unrelated human-anatomy posts, so it is not used. The narrower X query peaks Wed 14 Oct and is 52% below that peak on Mon 19 (a POP 5.3 window-closed signal for copycats; POP 5.4 judges repos by age and star velocity instead). Search demand for "how does X work" was not measured this run.

Market and competitors

TAM

Not sized this run — Scope: Educational explainer content in PT/ES/EN. Method: No market report fetched. (Basis: n/a)

SAMHypothesis

~$18K–$60K / yr (hypothesis) — Scope: Sponsor slots + teacher plans + custom figures. Method: Revenue hypothesis × 12 (HBV assumption). (Basis: HBV assumption)

SOMHypothesis

~$18K–$60K ARR (hypothesis) — Scope: Month-9 run-rate. Method: as SAM. (Basis: Low (hypothesis))

Competitors

Know.it (animated how-things-work library), Animagraffs (paid animated infographics), Auto Veteran (interactive machine explainers), AskGif, Vectree (visual explainers), Bartosz Ciechanowski (hand-made interactive essays); the maintainer's own free galleries; agent ports of the skill.

Business model

Monetization

Free library pages with labeled sponsor slots priced with traffic (education, hardware and tool brands); teacher plan with embeds, classroom mode and printables; paid custom figures with a queue. No approved price.

Revenue hypothesis (monthly)Hypothesis

~$1.5K–$5K/month at month 9 (HYPOTHESIS: 300 figure pages, 150k monthly visits, 4 sponsor slots at $150–$400 + 100 teacher plans at $5 + 20 custom figures at $19).

Jobs to be done

When I need to understand how a machine or system works for school or out of curiosity, I want to play with an interactive model I can take apart and slow down, so I can understand it fast and share it with classmates.

HXC

Larissa, 16, Belo Horizonte (illustrative) · High-school student preparing for ENEM; learns from YouTube and Google. Buying signal: She searches "como funciona um motor a jato" and finds only static diagrams; a page where she can take the engine apart and slow it down would be shared in her class WhatsApp group.

Build and go-to-market

Tech stack

Next.js on Vercel; Anatomy skill (MIT) run by coding agents in background jobs; static SVG/HTML custom elements; Stripe; Plausible

GTM channels

SEO/GEO pages per "how does X work" query in PT/ES/EN; embeddable figures with a backlink (embed loop); "request a machine" voting queue; faceless clips of figures moving on TikTok and Shorts

Risks

Main risk

Generation cost and quality: good figures take from minutes to many hours of agent time and the skill admits Claude does not always see visual faults, so the library may grow slowly and need human review; the MIT license also lets anyone, including the maintainer, ship the same wrapper.

All risks

Value: High — Slow, costly figure generation | Usability: Attention — Factual errors in education content | Feasibility: Attention — Easy to copy (MIT) | Business Viability: Unvalidated — Sponsor demand on education pages

Next validation step

Publish 20 Portuguese figures on top school topics in 7 days; kill if fewer than 5,000 organic visits or fewer than 30 embed or custom-figure requests in 45 days.

    PaidToStudyAbroad-powered scholarship finder

    A searchable, multilingual finder of fully funded study-abroad routes (government scholarships, tuition-free countries, paid PhDs, paid apprenticeships) built on the official-source list from the PaidToStudyAbroad repo.

    Why it scored lower: Crowded scholarship-directory market and unclear content license.

    LearnHarness-powered hosted tutor

    A hosted, no-API-key web version of the open-source LearnHarness tutor (measure → plan → teach → practice, with a personal knowledge graph), in Portuguese and Spanish.

    Why it scored lower: The maintainer is likely to launch the same hosted, managed-key version.
