5 Essential GPTs: AI assistants to speed up and improve work

Oct 24, 2025

In this live session, Tim Çakır, our CEO, built 5 essential Custom GPTs that every business needs today — turning ChatGPT from a general assistant into a specialized business powerhouse.

We covered:

  • What Custom GPTs are and how they work.

  • How to design GPTs for specific business functions.

  • Live demos building five GPTs from scratch:

    1. Precision Pen – a writing assistant for proposals, emails, and marketing copy.

    2. Data Insight Analyst – for spreadsheet and report analysis using the code interpreter.

    3. Project Navigator – for project planning and team coordination using Notion.

    4. Research Pilot – for market and competitor research with web and data capabilities.

    5. Customer Quadroptile – for customer communication using brand tone and Zapier integrations.

  • How to connect GPTs with tools like Notion, Google Drive, and Slack.

  • Best practices for using model types, enabling capabilities, and adding company knowledge.

Tim showed step-by-step examples of creating GPTs that write in your brand voice, analyze spreadsheets, plan projects, perform research, and assist with client communication — all in one ecosystem.

Main takeaways:

  • Start simple with “Create” mode, then refine in “Configure”.

  • Add brand and workflow context to make GPTs company-ready.

  • Combine multiple GPTs in a single workflow for powerful results.

  • Custom GPTs at 90–95% completion already deliver strong business impact.

  • The future of work lies in building specialized AI teammates, not generic chatbots.
