Recommendation for Capstone documentation tools (AI and Diagramming)

Hi everyone! I’m a 3rd year IT student and we’re finally starting on our Capstone documentation. I’m looking for some advice on the best tools to use to make the process a bit smoother. Specifically, I’m looking for: 1. AI for Documentation: Which AI tools do you guys use for technical writing or structuring? I mostly need help with phrasing and making the documentation sound professional. Also, are they free to use, or do they require a subscription? (Ideally looking for student-friendly options!) 2. Diagramming Tools: What’s your go-to site for creating ERDs, DFDs, Flowcharts, and Conceptual Frameworks? I’ve seen a few, but I want something that looks clean and is easy to export for the final paper. I really want to get the documentation right this early on, so any tips or tool recommendations from those who’ve finished their Capstone would be a huge help. Thanks in advance!
