An honest comparison — sources linked below

A beautiful plan for the idea.
Kitty checks the idea first.

The short answer: IdeaBuddy is a guided business-planning platform — $15/mo Dreamer, $20/mo Founder, 15-day free trial — that turns your assumptions into a structured plan with real financial projections. kitty.build is validation and execution: nine boards research the live market, cite what they find and return a free GO / PIVOT / NO-GO verdict, then the same product builds the site, writes code into your GitHub repo and runs the venture. Plan versus proof — you may honestly want both.

What IdeaBuddy does well

  • Genuinely good financial modelling — the only tool here that takes projections seriously
  • Produces a real business plan document, which banks, grant bodies and visa applications still ask for
  • Cheap: $15–$25/mo, with annual discounts advertised up to 60%
  • Guided structure is reassuring for first-time founders who do not know what questions to ask

Where IdeaBuddy falls short

  • It is a planning tool, not a research desk — the numbers are yours, it just organises them
  • AI requests are capped and the free tier's 10 requests barely scratch the surface
  • Public sources quote the Founder tier at both $20 and $25/mo
  • No execution, no live market research, no ongoing operations

When IdeaBuddy is the better buy

If you need a formal business plan with financial projections — for a lender, a grant application or a visa — IdeaBuddy does that job better and cheaper than anything else on this page, kitty.build included. We produce a verdict, a research pack and a build kit, not a bank-ready plan document with a five-year P&L.

Our verdict on IdeaBuddy in 2026

IdeaBuddy is the strongest business-planning tool in this comparison and the only one that treats financial projections as a first-class deliverable. If someone has asked you for a business plan — a bank, a grant committee, an immigration officer — this is the cheapest sane way to produce one. It is not validation: the plan organises your assumptions rather than testing them, and a beautifully structured plan for a product nobody wants is still a plan for a product nobody wants. Validate first with something evidence-based, then use IdeaBuddy to write it all down properly.

Frequently asked

Is IdeaBuddy free?
There is a 15-day free trial with no credit card, and their own plan page lists a free tier limited to one idea and 10 AI requests. Capterra records no permanent free version, so treat the free tier as a trial and check their pricing page before relying on it. Paid plans run $15–$25/mo.
Does IdeaBuddy validate your idea?
It gives an Idea Score and validation testing, but it scores what you enter rather than what the market is doing. That is planning, not validation. Pair it with an evidence-based tool that researches live sources before you commit to the plan.
How much does IdeaBuddy cost?
Dreamer is $15/mo, Founder $20/mo and Team $25/mo according to Capterra's tracker, with annual billing advertised at up to 60% off. IdeaBuddy's own blog has quoted Founder at $25/mo, so the numbers differ across sources — their live pricing page is the one to trust.
Is IdeaBuddy good for a bank loan application?
That is its strongest use case. The business plan editor and financial projections produce exactly the document lenders and grant bodies expect, exported to PDF, Word or Excel.
Should I switch from IdeaBuddy to kitty.build?
Only if the gap you keep hitting is the one kitty.build closes. kitty.build is the only tool in this set that both refuses to build a bad idea and builds the good one. Nine boards research the live web, cite what they find and return a GO / PIVOT / NO-GO verdict for free; if the verdict is GO, the same product ships the site on your domain, writes the code into your GitHub repo and runs daily cycles where a task only counts as done with evidence attached. The trade is that it is a subscription and it is opinionated. If you want a single document, or you want to art-direct every pixel yourself, something else on this list fits you better. Where IdeaBuddy still wins: If you need a formal business plan with financial projections — for a lender, a grant application or a visa — IdeaBuddy does that job better and cheaper than anything else on this page, kitty.build included. We produce a verdict, a research pack and a build kit, not a bank-ready plan document with a five-year P&L. The first kitty.build verdict is free with no card, so you can find out without cancelling anything.
