Swipefast is a checkout for coaches, consultants and creators who sell courses, memberships, templates and coaching. Instead of clicking through settings, you tell your AI what you sell. Claude, ChatGPT or the AI app you already use builds the whole checkout as a draft: the price, an order bump, a one-click upsell and the sales page. You read it, press Approve and start selling. Nothing goes live without you, and on a live checkout anything that touches money waits for your approval. Your AI can also tell you what sold this month, where your buyers came from and which order bump earns the most. Pip, the Swipefast penguin, sends you a sale alert every time someone buys. Payments run through your own Stripe account. Start your 7-day free trial for $0.

It provides a deterministic, client-side engine that runs entirely in the user's browser, ensuring 100% privacy, zero API costs, and instant results under 10ms.Prompt Rewriter & Compiler: Refactor and compile prompts for optimal performance on Claude, Gemini, and GPT models.System Prompt Generator: Synthesize production-grade LLM system prompts with role parameters, JSON schemas, and anti-leakage constraints.Prompt Checker: Score prompts across six core dimensions — structure, memory & state, context grounding, trust & accuracy, PII & privacy, and security & safety — with diagnostic rule analysis.Prompt Optimizer: Reduce token length and estimate multi-model cost savings through heuristic trimming.Injection Scanner: Detect multi-vector prompt injection and red-teaming threats, including DAN jailbreak patterns.AI Jailbreak Detector: Perform 4-tier hybrid edge threat scanning with sub-25ms response times and cryptographic attestation.AI Auditor: Audit LLM response accuracy, test automation execution, and validate llms.txt standards for enterprise readiness.The tool is ideal for pre-deployment validation, CI/CD pipeline integration, and regulated industries (healthcare, finance, legal) where data must never leave the device. By replacing LLM-based prompt graders with a deterministic rules engine, AIQualityHQ eliminates variability, latency, and data exposure risks.
