Which tool do you plan to use?

Understand the estimate

Can it estimate changes to existing projects?

Structural analysis for changes is already available: it considers the affected scope, the effort to preserve what works, risk and reuse. Conversion of that analysis into credits is still being calibrated.

How does the estimate work?

We convert your project's diagnostic into scope points, apply multipliers for clarity, design, codebase size and project stage, add risk and rework, and present a range. It is our own heuristic, not an official platform formula.

What are Lovable credits?

Credits are the platform's consumption unit. Each agent interaction consumes credits, and Plan Mode costs 1 credit per message. Plans include a monthly credit allowance.

What increases consumption?

Undefined scope, strict visual references, external integrations with unclear documentation, databases with many tables and policies, refactoring existing projects and multiple decision makers are the main causes of rework and extra consumption.

Why a range instead of an exact number?

AI-built projects vary with execution, scope clarity and direction changes. A single number would imply false precision. A minimum/likely/conservative range reflects reality better.

How to choose the most economical plan?

Compare your estimated monthly usage with the credits included in each plan and the cost of extra credits. A bigger plan is not always cheaper: it depends on your timeframe and monthly volume.

Frequently asked questions

Is the calculator free?
Yes. There is no charge to use the estimate. Acceptance of the Terms and Privacy Policy is required.
Do you have access to my project?
We do not directly access your project. The diagnostic is produced by your own AI agent. With your consent, we store only the structured data and result needed to deliver and improve the estimate; we do not store the raw pasted text.
Is this an official platform estimate?
No. It is an independent heuristic created by iRMarketingStudio.
Why is only Lovable available?
Each platform has its own consumption model. We started with Lovable; others will follow with dedicated engines.
Are the prices up to date?
Commercial values are volatile. We show the last verification date and never recommend options without a confirmed price.
Can I use this to quote a client?
Use it as a range reference, never as a fixed price. Actual usage may vary.
Do you show values in BRL?
Yes. We show USD and a BRL estimate using US$ 1 = R$ 5.00 as a reference, not a live exchange rate.
