The Idea Scorecard
You already had the idea. This tells you if it is worth your evenings.
The Idea Scorecard scores a product idea out of 100 on four things: whether the pain is real, whether anything similar already sells, whether you can name the buyer specifically, and whether you could reach those people without paid ads. Under 50 means do not build it. Over 70 means it is worth testing, not building.

The prompt
You are going to score one idea for me, honestly, and tell me whether it is
worth my evenings.
Be stingy. A high score has to be earned with evidence, not encouragement.
A low score is a favour: it just saved me weeks. Never invent a statistic,
a competitor, or a quote. If you cannot verify something, say so out loud
and score it low.
First, ask me this and wait for my answer:
"What's the idea, and who is it for? If you don't have one yet, tell me
instead what you know, do, or care about, and who you could genuinely
help."
If I don't have an idea yet, don't invent one for me. Pull it out of what
I told you: name one SPECIFIC group of people (not "everyone"), name the
real problem they already work or pay to avoid, then suggest one to three
small products that solve it. Small enough for one person to finish. Let
me pick one.
Then score it out of 100, twenty-five points each:
PAIN Do people feel this often and say it out loud? A mild
annoyance scores low. Something they already pay to avoid
scores high.
PROOF Does anything comparable already sell? Competition is
proof of demand. A completely empty market usually means
empty demand. Score that low and tell me why.
SPECIFICITY Is the buyer specific? "Everyone who wants to be
productive" is near zero. "First-year supply teachers
drowning in lesson planning" is high. Score what I
actually said, not what it could become.
REACHABILITY Could one person with a small audience put this in front
of its buyers? If it needs paid ads or a big platform to
even test, low.
Then give me exactly this, short and plain, no preamble:
Idea Score: __/100
Pain: __/25 one line why
Proof: __/25 one line why
Specificity: __/25 one line why
Reachability: __/25 one line why
Verdict: Under 50, say "don't build this yet" and why.
50 to 69, say "not yet, fix ___ first".
70 or over, say "worth testing" and name the smallest test.
Biggest risk: The ONE thing most likely to kill this. One sentence.
Never score above 70 without at least one real piece of evidence under
Proof.
Last thing. If the score is 70 or over, tell me the smallest possible
version I could put in front of a real person THIS WEEK to see if anyone
actually wants it. Not the finished thing. The smallest honest test.What to do next
