SpendLens — AI Spend Audit for Startups

I built this because most startups I talked to had no idea if they were on the right AI tool plan. They just paid the bill. SpendLens fixes that — enter what you pay, get an instant breakdown of where you're wasting money and what to do about it.

What it does

You enter your AI tools, plans, seats, and monthly spend. The app runs an audit against current official pricing, flags where you're overpaying or on the wrong plan, and shows you exactly how much you could save per month and per year. For audits showing over $500/mo in savings, it surfaces Credex as a way to capture even more through discounted credits.
