Lessons from Shipping Three AI MVP Side Projects
A developer recounts lessons from three AI side projects that gained real users after an earlier failed attempt. Key learnings: build the smallest working MVP instead of owning full AI infrastructure; pick a single user and workflow (build for your own pain first); and avoid hosting models yourself—use pay-as-you-go APIs or aggregators to minimize cost and friction. Concrete examples include a one-file Python commit-message generator (built in an evening), a standup-bot that evolved from a personal script into a Slack bot with 23 active users, and cost comparisons showing API usage often far cheaper than self-hosting. The author recommends prioritizing speed to prototype, using a single API call where possible, and shipping quickly to real users.
Practical developer guidance on building and shipping LLM-based MVPs; offers operational tips (avoid self-hosting, use API aggregators, limit scope) useful to engineers but not industry-shifting.

Key Takeaways & Evidence Grounding
- Author shipped three AI side projects after a prior failed project that incurred $200/month in model hosting before anyone used it.
- A commit-message tool was built in one evening using the OpenAI API as a single Python file; within a week 47 people had forked it.
- A standup bot that summarized git activity became a Slack bot with 23 active users after iterating from a personal script and cron job.
- Reported running costs: the commit-message tool cost about $0.03 per day and the standup bot about $0.10 per day using API calls.
- Author recommends using a pay-as-you-go API aggregator (example: tai.shadie-oneapi.com) to access multiple models (GPT-4, Claude, Gemini) and avoid self-hosting.

Lessons from Shipping Three AI MVPs
A developer recounts how they shifted from over‑engineering to a rapid shipping approach and launched three AI‑powered MVPs for real users over two months. The projects were: a one‑afternoon blog title generator (served via a single Node.js endpoint and OpenAI API) that attracted 47 unique visitors on day one; an AI‑powered Hacker News email digest using Google Forms, GitHub Actions and SendGrid with GPT‑4 for summaries; and a personal notes chat interface built first with TF‑IDF similarity over plain text files before migrating to vector search. The author spent about $80 in API credits, recommends prototyping with the simplest possible solutions, and says using a model API aggregator (tai.shadie-oneapi.com) helped avoid early infrastructure lock‑in.
Developer Builds a Personal AI App — Lessons Learned
A developer published a first-person account of building a simple AI application from scratch. They used LLMs via API, a basic frontend, and deployed the app to a cloud platform (e.g., Vercel). The build process involved substantial debugging: missing or incorrect model endpoints (examples include openchat/openchat, mistralai/mistral-7b-instruct, and google/gemma-7b-it), configuration errors, and deployment issues such as environment variables, API keys, and runtime build failures. The author emphasizes that debugging and deployment are where most learning occurs, that not all models are plug-and-play, and that practical experience matters more than passively following tutorials. The project ultimately produced a working live AI app and the author encourages others to start building even before they feel fully ready.
Inithouse Shares How It Ships Multiple AI Products
In a 2026 blog post, Inithouse describes its approach to shipping a growing portfolio of AI products in parallel. The team starts by validating a single MVP, standardizes a shared tech stack (React SPA frontend, Supabase backend), and uses a common analytics and reporting layer across products (GA4, Google Search Console, Microsoft Clarity). They automate repetitive reporting and audits, document each product with a single YAML config, and prioritize measuring early user retention to decide which MVPs to scale. The post lists example products (Magical Song, Be Recommended, Ziva Fotka, Pet Imagination, Verdict Buddy) and outlines common pitfalls and lessons learned for multi-product AI teams.
