A spam filter for startup thinkingNot a generator. A reality engine.

Stop wasting your brain on ideas that do not need to exist.

Full of Shit tells you whether your startup idea is real — or just disguised repetition. It detects vague language, crowded categories, missing buyers, and fake differentiation.

Run a reality check

We don’t validate ideas. We eliminate bad ones before they kill your time.

BS Score

How much is marketing fog

Redundancy

How crowded / copycat it smells

The fastest validation step

POSITIONING

Is this actually forward progress… or just activity that feels like progress?

Founders are drowning in motion: decks, roadmaps, landing pages, “AI agents,” and vague platforms. Most of it is just… noise.

This engine is built to say the quiet part out loud: what’s missing, what’s redundant, and what would have to be true for this to be worth anyone’s time.

Core principle

If you can’t name the buyer, the pain, and the wedge — you don’t have a startup. You have a sentence.

LIVE REALITY CHECK (MVP)

Paste the idea. Get the truth.

Deterministic heuristics. No external APIs. No “infinite imagination.” Just the signals that usually decide whether a startup is real… or full of it.

VERDICT

Maybe — but it’s under-specified and flirting with redundancy.

Buyer is at least hinted. Pain is vague — nothing sounds urgent or expensive. No payment path mentioned — danger of building a free toy. No wedge — sounds copyable.

Time waste risk: Low

Probably not a waste. Still prove it.

WHY IT MAY FAIL

No concrete pain, risk, or cost described.
Nothing suggests budget authority or willingness to pay.
Doesn’t connect buyer → pain → solution in a crisp way.
No edge stated (why you, why now, why better).

MAKE IT NOT SHIT

For a specific buyer, when they hit a recurring painful moment that costs time/money/risk (weekly), we replace the current workaround with ______, delivering ______ in <14 days via a wedge you can prove (distribution, data, compliance, workflow lock-in).

NEXT VALIDATION MOVE

Write a pricing hypothesis (who pays, how much, why now). Offer a paid pilot to 3 target buyers.

NOTE

This is deliberately brutal. The goal is not to “feel inspired.” The goal is to remove fake progress and force buyer truth.

THE 2.0 SYSTEM (COMING NEXT)

Narrative vs activity vs reality.

Version 1 is a deterministic heuristic reality check. Version 2 becomes a structured “reality engine”: it forces the idea through buyer truth, problem truth, and edge truth — then demands proof.

Narrative: the story founders tell themselves.

Activity: the work that feels productive (but isn’t).

Reality: what buyers pay for, and what pain they admit.

Buyer check

Who has budget authority? What would they cut to pay you?

Pain check

What breaks weekly? What costs money or creates risk? Where are the receipts?

Redundancy check

Is this already shipped by 20 incumbents? Is your wedge provable?

Value creation check

Are you creating new value or rearranging existing tools with marketing?

Time-waste check

How fast can you disprove yourself? The faster, the better.

WHO THIS IS FOR

Built for people tired of fake startup progress.

Founders

Kill the idea fast, or sharpen it into a wedge worth validating.

Investors

Pressure-test differentiation, buyer truth, and “why now” in minutes.

Accelerators

A reality filter for cohorts: less fluff, more buyer truth.

Operators

Evaluate “internal startup” projects before they consume quarters.

Studios

Run idea intake through a repeatable brutality pipeline.

Venture builders

Pick bets with real pain, real buyers, and provable wedges.

VISION

A reality engine for startups.

The world doesn’t need more ideas. It needs fewer bad ones — killed faster. Full of Shit exists to compress “wasted months” into “wasted minutes.”

Run the engine

Brutal truth now. Beautiful product later.
