CostGPT

CostGPT AI is a web-based AI software cost estimator for founders, startups, freelancers, and development teams that need quick, structured plans for new product ideas.

It turns a short idea description (or a reference URL) into an actionable project plan, including:

• Cost and timeline estimates with a consolidated project overview
• Feature breakdowns and dependencies to clarify scope and prerequisites
• Sitemaps and user flows, plus user stories for product planning
• Sprint milestones to support delivery planning and sequencing

Pricing: Freemium. The free plan includes project estimates, core features, and dependencies. A $19 one-time payment unlocks premium outputs such as sitemaps/user flows, user stories, and milestones (no subscription).

What makes it notable is its focus on fast, proposal-style planning for early-stage software projects, using a model trained on 2,000+ historical projects and returning estimates in under 5 minutes (positioned as ballpark figures, not exact quotes).
