I Tried EvaluateMyIdea.ai. Then I Built Something Better.

Last month, I had an idea for a side project. Nothing earth-shattering — a tool that helps freelancers track unpaid invoices. Before I spent a weekend building it, I wanted a quick sanity check. You know, the "is this even worth my time?" kind of check.

So I Googled "evaluate my business idea" and found EvaluateMyIdea.ai. Looked slick. Promised AI-powered validation. Cool, I thought. Let me try it.

Here's what happened.

The Signup Wall Problem

First thing: I had to create an account. Email, password, the whole thing. I hadn't even typed my idea yet, and they already wanted my contact info.

I get it — they need accounts for their credit system. But I just wanted a quick score. I didn't want to commit to a platform before I even knew if it was useful.

I signed up anyway. Got my first evaluation for free. The AI wrote about 500 words about my invoice tracking idea. Some of it was generic ("make sure you have product-market fit"). Some was genuinely helpful. Fair enough.

Then I wanted to test another idea. That's when the paywall appeared.

The Credit System Trap

EvaluateMyIdea.ai uses a credit system. Your first evaluation is free. After that, you buy credits. Each additional evaluation costs money.

Now, here's the thing about idea validation: you rarely nail it on the first try. Most founders iterate. You test one angle, learn something, then tweak and test again. A credit system punishes exactly the behavior that leads to good ideas — iteration.

I had three ideas I wanted to compare. One free, two behind a paywall. That didn't feel right.

The Privacy Question Nobody Asks

Here's what bugged me most, and what most people don't think about: when you type your business idea into an AI-powered tool, where does that text go?

It goes to a cloud API. Your idea gets sent to OpenAI or similar providers for processing. That means:

• A third party now has your business idea in their logs.
• Your idea might be used to train future AI models (depending on the provider's terms).
• You have no control over what happens to that text after you hit "submit."

For a silly side project, maybe that doesn't matter. But if you're serious about an idea — if it's something you think could actually work — do you really want it sitting in someone else's database?

What I Built Instead

After that experience, I built ValueMyIdea.com. It does the same core job — tells you if your business idea is worth pursuing — but with a completely different approach.

Instead of feeding your idea to an AI and getting back a wall of generated text, ValueMyIdea asks you 12 structured questions. Things like: How painful is the problem? How big is the audience? Can you build an MVP? What's your budget?

Then it calculates a feasibility score from 0-100, breaks it down into four categories (Market Fit, Revenue Potential, Execution Feasibility, Financial Health), and gives you actual numbers — estimated total cost of ownership, projected revenue, breakeven timeline, and specific risks.

The key differences:

No Signup Required

You open the site, answer 12 questions, get your score. That's it. No email, no password, no account creation. If you want to save your scores and compare ideas over time, you can optionally create a free account. But it's not required to use the tool.

I've seen the data on signup walls. They kill 60-70% of your traffic. People bounce before they even try the tool. If the whole point is to help people evaluate ideas, why put a barrier in front of that?

Everything Runs in Your Browser

This is the big one. All scoring happens client-side, in JavaScript, right in your browser. Your idea text is never sent to any server. There's no AI cloud call. No API. Nothing leaves your device.

That means:

• No third party ever sees your idea.
• Nothing to train AI models on.
• Results are instant — no waiting for API responses.
• Works offline if you've already loaded the page.

Numbers, Not Paragraphs

AI validators give you paragraphs. Sometimes useful paragraphs, sometimes filler. ValueMyIdea gives you numbers.

Your idea scored 72/100. Market Fit is 85%. Execution Feasibility is 58% — that's your weak spot. Your estimated Year 1 cost is $4,200. Projected MRR at month 12 is $1,800. Breakeven in 7 months. Two high-risk flags: small initial market and long time to MVP.

You can act on numbers. You can compare two ideas side-by-side using numbers. "Idea A scored 72, Idea B scored 61" tells you more than two pages of AI-generated text.

Free PDF Reports

After scoring, you can download a complete PDF report with everything — score breakdown, cost analysis, revenue projection, risk assessment, and recommended next steps. It's free. No credits, no paywall.

Want to share it with a co-founder or mentor? Just send them the PDF.

The Honest Comparison

When to Use Which

I'll be fair. EvaluateMyIdea.ai has strengths. If you want detailed, narrative feedback on your idea — the kind of thing a mentor would write in an email — AI-generated reports can be helpful. Their roadmap feature guides you from validation to market entry, which is valuable if you're a first-time founder who needs more hand-holding.

ValueMyIdea is better for a different type of founder. The one who wants fast, quantitative answers. The one who's iterating between multiple ideas and needs a quick comparison. The one who cares about privacy. The one who doesn't want to create yet another account for yet another tool.

I built it because that's the founder I am. If you're anything like me, you'll probably like it too.

What People Ask

"But isn't AI analysis more thorough?"

More words, yes. More thorough? Not necessarily. AI validators give you paragraphs that sound smart but often say generic things. "Make sure you validate with real customers." "Consider your competitive landscape." You already knew that. ValueMyIdea gives you specific numbers based on your specific inputs. That's more actionable.

"Why is it free?"

Because the scoring runs in your browser and costs us nothing per evaluation. No API calls, no server-side processing. We might introduce premium features later, but the core scorer will always be free.

"Is my idea really safe?"

Check our data security page. In short: anonymous users leave zero trace. Your idea text never hits a server. It's processed entirely in JavaScript on your device. We literally couldn't read your idea even if we wanted to.
