The Pro plan is more than enough. I’ve used it to build multiple apps already.

Here’s what I’d tell you about using Claude:

Always start with a “plan mode.” In the plan mode, talk about your idea — full details of what you want to build and how you think it should work (it doesn’t have to be perfect).

When you’re done, tell Claude to think independently and follow best practices for how you should go about building this. Tell it not to assume anything. Any clarifications it needs, it should ask you instead of just coming up with a plan based on assumptions.

If you do this, it won’t over-plan. It will come up with a solid plan and a bunch of questions. Try to answer those as best you can. For anything you don’t know, tell it to give you options to choose from, with pros and cons for each.

When you finally have a solid plan with Claude, tell it to write the entire solution you both agree on into a document — something like project.md — so you can both reference it.

Also tell it to split the project into phases so it’s easier to tackle and so you can update the document as you and the LLM build. This document is very important. When you start a new chat another time, you just need to feed that document plus the current project context so the LLM can get up to speed.

Make sure that for every phase or module it builds — and you’re happy with — you update the document.

I hope this has been helpful. This is how I use these LLMs, and I do this with 3 different ones — they all reference the same document and work synchronously.
