Cryptographic Per-Vendor Email Identity System

C6/10April 5, 2026
WhatA service that generates truly unique, non-guessable email aliases for every vendor signup, with automatic forwarding and one-click disable, replacing the easily-defeated plus-addressing and pattern-based alias schemes.
SignalCommenters point out that plus-addressing is routinely stripped by services, and even custom-domain aliases using predictable patterns like [email protected] can now be reverse-engineered by cheap LLMs — current alias approaches are fundamentally broken.
Why NowLLMs can now cheaply guess alias patterns at scale, rendering the most popular privacy technique used by technical users ineffective — and Apple's Hide My Email has proven mainstream demand for random aliases but only works within Apple's ecosystem.
MarketTechnical professionals and privacy-conscious consumers; Apple charges for iCloud+ ($1-10/month) and SimpleLogin was acquired by Proton for ~$30M, validating willingness to pay. Gap: cross-platform, non-ecosystem-locked solution with leak attribution built in.
MoatEach alias becomes a data point in a leak-attribution network — the more vendors tracked across more users, the faster the system can identify which vendor leaked and alert all affected users simultaneously.

Intelligent Token Compression Middleware for LLM APIsP6/10An API proxy layer that automatically compresses prompts and responses to minimize token usage while preserving output quality, sitting between applications and LLM providers.
LLM Output Quality Benchmarking for Prompt StylesC5/10A platform that systematically tests how prompt formulation — verbosity, register, typos, compression — affects output quality across models, giving developers empirical guidance on how to prompt.
AI Code Architecture Enforcement and Refactoring ToolP7/10A development tool that continuously monitors AI-generated codebases for architectural drift, spaghetti patterns, and structural decay, then automatically refactors or flags violations before they accumulate.
AI Code Quality Control Layer for CRUD AppsC6/10A middleware that intercepts AI-generated code before it reaches the codebase, evaluating whether the solution uses the simplest possible approach (e.g., a single SQL query vs. an elaborate multi-layer abstraction) and rewriting or rejecting over-engineered output.
AI-Powered Collaborative Software Design WhiteboardC6/10A structured AI conversation tool purpose-built for the software architecture design phase — supporting extended back-and-forth exploration of tradeoffs, relational modeling, and system design before any code is written.
Zero-Config Project Scaffolding That Skips the TediumC5/10An AI-powered tool that instantly generates fully configured project foundations — dependencies, build pipelines, CI, base styling, auth — so developers can skip straight to the unique logic they actually want to build.
