About Spendict
Spendict answers one question, and tries to answer it honestly: should you spend money running this ad? It’s a scoring API that returns a deterministic run / fix_first / kill verdict on any ad creative — before the budget moves, not after.
What we build
Generating ad creative got cheap. Deciding which of it deserves budget did not. Most tooling sits on either side of that gap — producing more variants, or explaining performance after the spend is gone — so Spendict was built for the step in between: an independent judge that scores a finished ad and returns a verdict a machine can act on.
It scores seven dimensions — hook, angle, clarity, audience resonance, platform fit, CTA and compliance — names the single most likely reason the ad will underperform, and returns one of three verdicts. It’s platform-specific across Meta, TikTok, Google, LinkedIn and YouTube, and it’s reachable over MCP, a REST API, a CLI, or a drop-in agent skill.
Who it's for
- Developers and agent builders wiring a quality gate into an automated creative pipeline.
- Agenciesthat need a consistent, defensible reason a client’s creative was held back.
- Performance teams producing more variants than any human can review before launch.
The principles it's built on
Three commitments shape the product, and they’re the reason it behaves the way it does:
- The server decides, not the model.The score and the verdict are recomputed server-side from fixed gates. A confident model can’t talk a weak ad past the gate.
- Same ad, same verdict. Determinism is the point — a gate you automate against has to be stable, and auditable after the fact.
- A verdict, not a vibe.A number between 1 and 10 doesn’t tell anyone whether to launch. Three outcomes and one named failure mode do.
