Developer builds LaTeX conversion business in 7 days using Claude Pro
A developer documented building a complete business in 7 days using Claude Pro for $23.60. The service, called The LaTeX Lab (thelatexlab.com), converts Word documents to LaTeX for PhD students and researchers submitting to journals.
Project timeline and components
Day 1 - Research and go-to-market plan: Claude researched the market, competitors, pricing, and customer pain points. The developer estimated this saved about $500 in consulting fees and a week of manual research.
Days 2-3 - AI agent development: Built an AI-assisted formatting pipeline as the core service delivery system. The developer valued this component at $5,000+ if outsourced.
Days 4-5 - Custom WordPress theme: Created a production-level WordPress theme from scratch, not using templates. Achieved page speed scores of 96 on desktop and 80 on mobile. For comparison, most premium WordPress themes score 60-70 on mobile. Estimated value: $1,000-$2,000.
Day 6 - SEO-optimized copy: Wrote all website copy with search intent in mind, including target keyword research, FAQs with schema markup, and meta titles/descriptions for every page. Estimated value: $800-$1,500.
Day 7 - QA, optimization, and launch: Tested everything, fixed edge cases, and deployed the live site.
Business context
The service targets a niche market of approximately 10,000 potential customers worldwide who need Word-to-LaTeX conversion for journal submissions. The developer identified pain points including weeks lost to LaTeX errors, automated tools breaking equations, and inconsistent freelancers.
Developer notes
The developer emphasized that Claude doesn't do everything perfectly and still requires human oversight: "You still need to know what you're doing. You still need to QA everything. You still need a brain." However, with clear ideas and effective prompting, the leverage can be significant.
Total estimated value of work completed: $7,200-$8,200 across research, AI agent development, theme building, and copywriting.
