๐Ÿ“… 3. Appointment Booking Without the Tech Headache Many competitors require full calendar integration, which can break or require upkeep. Postbot just texts your booking linkโ€”clean, simple, and flexible. โ†’ Fewer no-shows, less friction, and no added tools to manage.

๐Ÿ’ธ 4. Pay-as-You-Go Pricing With No Hidden Costs

How would you describe your primary audience?

A tool that requires zero technical setup and works out-of-the-box

A way to capture leads after hours, during lunch, or while theyโ€™re serving other customers

What's the story behind your product?

Postbot's answer:

Postbot was born from a simple, painful truth: small business owners are missing too many opportunitiesโ€”just because they canโ€™t pick up the phone.

The founding team had spent years building voice automation for big companies, helping them reduce support costs and improve customer experience. But what they kept noticing was this: the little guysโ€”the therapists, stylists, plumbers, and attorneysโ€”were getting crushed by missed calls, bad phone trees, and expensive virtual receptionist services.

Which are the primary technologies used for building your product?

Postbot's answer:

Voice AI & Natural Language Processing (NLP) Powered by large language models (LLMs) and speech-to-text / text-to-speech systems Enables natural, human-like conversations and intelligent FAQ handling Supports multi-language interactions (e.g. English, Spanish, French, German)

Telephony Infrastructure Built on top of scalable cloud communications platforms like Twilio or Plivo Handles call routing, voicemail fallback, number provisioning, and SMS delivery

Web Scraping & Knowledge Extraction Automated parsing of business websites using AI-enhanced scraping tools Converts content into structured, queryable formats for dynamic response generation

Who are some of the biggest customers of your product?

Postbot's answer:

Small Businesses

Polygraf.ai Reviews

  1. Good one

    This tool has one of the best ai (model) detectors, it really saved me when I was submitting my essay (it was 87% AI lol). Extension + web version is convenient, especially for students.

    ๐Ÿ‘ Pros:    Fast|Accurate
  2. Go longhorns
    ยท Bachelor of Computer Science at UT Austin ยท
    By far the most detailed AI detector I've ever used

    I transitioned from Turnitin to gptzero to Polygraf. they were all useless, as I got almost suspended due to my school almost failing me for using Grammarly. I can almost swear that that I did not use any other thing. So, Polygraf was the only one that showed that I had used AI but it was Grammarly.

    ๐Ÿ‘ Pros:    Shows whichai you used|Shows and highlights the section of the ai content|Shows humanized content
    ๐Ÿ‘Ž Cons:    File upload was not available when i was using it|Their website can be a little more student friendly
