Richard Kovacs is a Hungarian full-stack developer and security trainer based in the Budapest area who builds side projects in the evenings and shares the process on X. His background in security includes strong placings in the CrySyS Security Challenge, and by day he runs Konvert7, which offers AI engineering training, consulting and development for companies.
His indie products lean on AI and accessibility. Fyzz.chat brings models such as GPT, Gemini and Perplexity into a single chat app, with PDF chat and image analysis, so users do not need several subscriptions. ReadSonic is focused on making the web more accessible through text-to-speech, and LetterBox lets creators write a post once, tailor it per platform and schedule it to LinkedIn, X, Threads and Bluesky from one queue.
He has also released open source work for other builders, including Catalyst, a Next.js boilerplate, and HighlightCSS, a tool for animated headline effects on landing pages.
