Overall verdict

  • Sanebox is generally well-regarded for its ability to improve email management and productivity. Users often find it effective in decluttering their inbox and appreciate its compatibility with most email providers. However, the service is subscription-based, and its value may vary depending on individual email habits and needs.

Additional features include snoozing non-urgent emails, setting reminders for follow-up, and providing detailed email activity insights.

Questions & Answers

As answered by people managing Sanebox and ForthWrite.

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.

  • Would you trust some company that asks for your full email access and says they will only access your email headers for the sake of filtering out the junk?
    I see no specific issue with sanebox.com, however it appears that they are only offering a service you can do on your own. Honestly, do you really get that much SPAM? Source: about 4 years ago
