Possible disadvantages

  • Accuracy Limitations
    Like most AI detection tools, IA Checker may produce false positives or false negatives, especially as AI-generated text becomes more sophisticated and harder to distinguish from human writing.
  • Limited Transparency
    The exact algorithms and methods used for detection are usually not disclosed, making it difficult for users to fully understand or trust the scoring mechanism.
  • Potential Cost Barriers
    Depending on the pricing model, extensive or professional use of the tool might require a subscription or payment, which could be a barrier for individual or budget-conscious users.
  • Dependence on Evolving AI Models
    As AI writing tools continue to improve, detection tools like IA Checker may struggle to keep up, potentially reducing long-term reliability and accuracy.
  • Limited Public Information
    There is relatively little independent, third-party information or reviews available about IA Checker, making it harder for users to fully evaluate its credibility and effectiveness compared to more established detection tools.

Questions & Answers

As answered by people managing ForthWrite and IA Checker.

Which are the primary technologies used for building your product?

ForthWrite's answer

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.
