AssertKit

Shielded inboxes that appear the instant mail arrives — plus AI you can chat with about your PR security findings and project status. One account, three tools.

AssertKit puts three developer tools behind one account.

MAIL SHIELD — Shielded inboxes & aliases Pick any name @assertkit.com and a disposable inbox appears the moment the first message lands. One-time passcodes and magic links are detected and surfaced for a single tap to copy, then cleared. Star the mail you want to keep, search across addresses, and export when you need to.

ASK AEGIS — Chat your code review Ask plain-language questions about your pull-request security scans: what got flagged, how severe it is, and how to fix it. Aegis answers from your real findings — no dashboards to dig through.

ASK AUDIT — Ask about your project Get answers about project status, blockers, and signals across your sources and timelines, with charts when a picture says it faster.

WHY ASSERTKIT • Sign in with Apple or Google — no password to manage • Mail Shield is free • Honest, private by design: your inboxes and conversations are yours • One workspace on web and mobile

Mail Shield is free to use. AI features (Ask Aegis and Ask Audit) run on credits — new accounts start with free credits, and you can top up any time.
