From a vacancy to a structured application draft

The goal was not another general chatbot, but a guided workflow: understand the vacancy, select relevant arguments and generate an editable letter.

Product concept, information architecture, UI implementation, prompt logic and model API integration.

— Focus, tone and strengths are explicit controls instead of hidden prompt text.
— Groq and rotating free OpenRouter models load dynamically.
— Provider failures fall back to the next available model.

Next development step

Next I would add quality checks for facts, tone and repetition, plus side-by-side draft comparison.
