Document assistant
Build a tool that lets users search and summarize their own documents, with citations back to the source passages. The interesting engineering work is often in retrieval, permissions, chunking and a good user experience.
Study planner
A study assistant can turn a syllabus into a realistic plan, track progress and explain difficult topics. A useful version should be transparent about generated content and let the student correct the plan.
Developer helper
A focused tool can summarize build logs, explain errors or turn repository information into a project overview. The key is to keep the scope narrow enough that the result can be evaluated.
Content quality checker
Instead of automatically producing large amounts of content, build a tool that helps a human improve clarity, structure, accessibility or consistency. Human review remains the important final step.
What makes a project stand out
Show the problem, design decisions, tradeoffs, screenshots, limitations and what you learned. A portfolio reviewer learns much more from the engineering story than from a list of AI buzzwords.
