LabelSnap - Zero-Shot Visual Defect Classifier for Small Manufacturers
Small factories cannot afford $50k computer vision systems, so quality control still means a tired human squinting at parts on a conveyor. LabelSnap is a zero-shot visual defect detection API that a manufacturer can point a $200 webcam at and get defect classifications with zero training data. No ML PhD required.
FrameScout - Visual UI Regression Detector That Actually Explains What Broke
Your CI pipeline turns green, you deploy, and three users immediately email you that the checkout button is invisible on mobile Safari — congratulations, you have a visual regression that pixel-diff tools flagged as a 0.1% change and silently ignored. FrameScout uses computer vision to compare before/after screenshots at the component level, classifies what type of UI element changed and whether it is user-facing critical, and generates a Slack alert with a visual diff and a plain-English severity verdict.
ClipForge - AI Agent that Turns Long-Form Video into Multi-Platform Clips and Captions
Upload a 30-minute video, the AI agent auto-generates 8-12 short-form clips (optimized for TikTok, Reels, Shorts), extracts captions, adds branded watermarks, and queues them for publishing. One upload, 10 pieces of content.

RepoMap - Interactive Codebase Dependency Visualizer for TypeScript Monorepos

LogicProbe - Natural Language SQL Error Explainer and Auto-Fix Agent
Nobody reads Postgres error messages — they are written for database internals engineers who have been awake for 72 hours and hate you. LogicProbe is an NLP agent that takes your raw SQL error, your schema context, and your original intent in plain English, then outputs a plain-English diagnosis plus a corrected query with a line-by-line diff explaining what changed and why. Data analysts and junior devs will pay for this before you finish the landing page.
PrivacyGuard - PII Detection Layer Before Your Prompts Hit Any LLM
Every dev team has that one paranoid colleague who refuses to paste client data into ChatGPT — turns out they are right and everyone else is wrong. PrivacyGuard sits between your team and any LLM, scans outbound prompts for PII and sensitive data in real-time, and optionally reroutes flagged prompts to a self-hosted Ollama instance. Ship this to one fintech or law-adjacent SaaS team and charge $500/month before lunch.
