Kerprompt
Better Designs. Fewer AI Credits.
About
Kerprompt: Get to the creative output faster.
Stop burning AI credits watching LLMs invent bad color palettes and generic typography.
Kerprompt is a visual parameter-tuning engine that front-loads your design system baseline, generating highly-structured prompts for Cursor, Antigravy, any IDE or chat windows really...
Skip the back-and-forth iteration. Define the rules upfront, and force your AI to output professional-grade UI on the first try.
🚀 Key Features
- Dual Output Modes: Generate prompts for chat windows (Claude/ChatGPT) or export a
DESIGN_SYSTEM.mdfile as standing orders for IDE agents (Cursor/Windsurf). - Visual Token Engine: Dial in exact hex codes, border radii, spacing scales, and typography pairings before you generate a single line of code.
- Negative Prompting: Stop bad design habits instantly. Check a box to explicitly ban drop shadows, generic icons, or "Lorem Ipsum" placeholders.
🎯 Who It's For
- Founders & Hackers: Ship premium-looking MVPs out of the box without hiring a designer.
- Frontend Engineers: Establish strict UI boundaries so Cursor/Windsurf stop hallucinating bad styles.
- Designers: Prototype rapidly with AI while maintaining absolute control over the visual hierarchy.
LLMs waste massive amounts of time (and your credits) trying to guess your design system. Kerprompt solves this by establishing the baseline typography, spacing, and color rules before you ever talk to the AI.

What felt really fair about the season pass is that I don't forget about it and then I'm charged forever. The season pass gives you a very clear overview of these are the things you can get in this period of time if you spent this amount of money.
Season passes feel fair because they are time-bounded and require engagement — subscriptions feel unfair when users forget and keep paying
Nørvig identifies the psychological reason season passes outperform subscriptions for engagement-dependent products: they are inherently transparent. Users know exactly what they get, for how long, and the charge stops automatically. Subscriptions accumulate guilt when users stop engaging but keep paying — a feeling that accelerates churn and brand damage. For apps where usage is periodic or goal-oriented, the season pass model may fit better than perpetual subscription.
We started publishing reports and working with reporters to help them report on the issue — here's how many spam calls Americans are getting every month, here's how it's growing. When you accumulate multiple Wall Street Journal articles that reference you and Financial Times articles — that starts building a brand and organic halo.
Proprietary data plus press relationships beat direct ads — Robokiller built organic brand through spam-call reports
Falzon describes RoboKiller's content and PR strategy: the app had the largest dataset on US spam calls and texts, and Mosaic created a recurring monthly spam-call report that journalists and regulators (FCC, FTC) found genuinely valuable. The Wall Street Journal and Financial Times cited these reports repeatedly; cable news segments featured the data. No single press mention drove meaningful downloads — but the accumulated brand signal reduced CAC across all other channels and built credibility that converted skeptical users.
There's a play for whatever you're stuck on.
