Summary
Under 150 lines of Python, Shittu Olumide built a custom AI assistant he now uses regularly for research synthesis, drafting and file analysis instead of relying on off-the-shelf tools.
GPT-4o powers the assistant through LangChain, with DuckDuckGo search for current information, a custom file-reading tool, and SQLite-backed memory that preserves context across sessions.
Two weeks of use showed the biggest payoff in research work: summarizing three to five URLs fell from about 45 minutes to 4 minutes, while text-based files under roughly 50,000 words were handled reliably.
Olumide said he chose to build rather than buy for workflow control, data-location concerns around client material, and hands-on understanding of AI systems as the assistant market is projected to grow from $3.35 billion in 2025 to $21.11 billion by 2030.
