ZeroThreat.ai is an AI-powered web application and API pentesting platform designed to identify real, exploitable vulnerabilitiesโnot just surface-level findings. Built for modern engineering teams, it combines Agentic AI pentesting with a high-performance scanning engine to deliver up to 10ร faster, deeply validated security testing.
Unlike traditional DAST tools that rely on static signatures and generate excessive noise, ZeroThreat.ai executes adaptive, attacker-style workflows that evolve based on application behavior. Its interpreter-driven vulnerability intelligence continuously ingests emerging threats and newly disclosed CVEs, enabling near real-time detection updates and rapid CVE-to-exploit mapping.
The platform supports over 130,000 vulnerability checks, including native Nuclei template execution, and extends beyond known issues with zero-day detection through behavioral pattern analysis. It validates every finding through live exploit execution, ensuring only real, impactful vulnerabilities are reportedโwith clear proof of risk and exposed data.
ZeroThreat.ai is purpose-built for modern applications, with advanced browser automation for SPAs, authenticated testing, and complex multi-step workflows. It identifies critical issues such as auth bypass, business logic flaws, and workflow abuse that traditional scanners miss.
ForthWrite is an AI email writing assistant for Gmail and Outlook that learns your writing style from your real sent mail. The more you use it, the more it sounds like you. Get smart drafts in seconds, auto-draft replies before you open your inbox, and maintain your personal voice at scale. Free to start, no credit card required. Works inside Gmail and Outlook on the web.
How it works
ForthWrite captures your tone, sentence rhythm, and sign-offs from your actual sent emails, then uses that profile to generate drafts that match how you write, not a generic AI voice. Every draft you edit or send improves the model over time.
Key features
Who uses it
Professionals who send high volumes of relationship-critical email: lawyers, financial advisors, recruiters, account executives, founders, and anyone who wants their inbox handled without sounding like a chatbot wrote it.
Pricing

ZeroThreat.ai's answer
ZeroThreat AI delivers enterprise-grade security testing without the complexity. Unlike legacy tools, it requires zero configuration, integrates easily into CI/CD pipelines, and runs authenticated scans and logic tests that others miss. It helps teams move fast and stay secureโwithout slowing down dev cycles.
ForthWrite's answer:
Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.
ZeroThreat.ai's answer
ZeroThreat.ai's answer
Our primary audience includes DevSecOps teams, security engineers, and software development teams at startups, scale-ups, and enterprises who need scalable, automated, and accurate security testing across web applications and APIs.
ForthWrite's answer:
Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.
ZeroThreat.ai's answer
ZeroThreat AI was founded in 2024 by developers frustrated with slow, outdated security tools. The goal was clear: make penetration testing accessible, intelligent, and continuous. By using AI to automate attack simulation and remediation, ZeroThreat empowers teams to find and fix vulnerabilities earlyโwithout needing to be security experts.
ForthWrite's answer:
Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.
ZeroThreat.ai's answer
ZeroThreat AI combines the power of AI with developer-first design to deliver automated, penetration testing without the need for manual setup or security expertise. It offers unparalleled scan accuracy (98.9%), AI-generated remediation, and supports business logic testing, making it one of the most comprehensive DAST solutions for modern web apps and APIs.
ForthWrite's answer:
ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.
As a HealthTech SaaS provider, HIPAA compliance and patient data security are critical. Before using ZeroThreat, we depended on biannual manual penetration tests, which left us exposed to hidden vulnerabilities. ZeroThreatโs automated penetration testing and continuous vulnerability scanning now give us real-time visibility into risks. The AI-powered remediation guidance makes it easy for our engineers to fix issues quickly, and seamless integration with our SDLC ensures every code push is secure. Since adopting ZeroThreat, our compliance audits are smoother, our data is safer, and our team works more efficiently.
I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest endorsement I can give.
The Chrome extension lives inside Gmail and Outlook on the web. Open a thread, hit Alt+Shift+D, and a draft comes back in your voice, not a template. The free tier is real: 10 drafts per week, no API key, no credit card. Voice matching is included on free, because that is the point.
What keeps it useful compared to Gemini or a chat tab: it learns from what you actually send. Every edit you make before hitting send becomes a signal. Over time the drafts drift closer to how you really write, and the dashboard shows the improvement curve so you can see it happening.
The web compose surface lets you draft from forthwrite.ai without installing anything, useful for people who want to try before committing to the extension.
Standard adds recipient-aware and intent-aware drafting plus AI coaching. Pro adds auto-draft (replies waiting when you open Gmail), batch replies, and Prompt Lab for version-controlling your prompts. Teams adds a shared persona and seat-level analytics.
ForthWrite is not for everyone. If you just need quick replies and tone does not matter, Gemini is free and already in your inbox. ForthWrite is for people where tone does matter: client communication, relationship-driven threads, external correspondence where sounding off costs something real.
Disclosure: I am the founder and use it daily. Happy to answer questions in the comments.
