Introduction

ChatGPT has evolved from a helpful chat companion into a full-blown automation engine. If you are still using it only for single prompts, you are missing out on a massive productivity boost. Over the last few months I’ve been building workflows and testing hidden settings that let ChatGPT act like an assistant that can research, click, file, remind, integrate and even build new tools for you. In this guide I walk through 10 secret ChatGPT features and settings I use every day to automate repetitive tasks, connect hundreds of apps, build custom agents, and give ChatGPT real context about my work and life.

Primary keywords included in this article: ChatGPT features, ChatGPT automation, connect apps to ChatGPT, ChatGPT agents, Zapier integration, Atlas browser, memory management.

Outline

Why these features matter

There are two big ideas I want you to walk away with. First, ChatGPT is no longer just a text generator. It can act inside your browser, interact with apps, schedule itself, and hold memory about how you work. Second, you can stitch ChatGPT into your existing systems and tools. With the right setup, it will perform entire workflows autonomously — saving hours of manual work every week. Below I break each hidden feature down, explain how to enable it, give real use cases, and offer responsible use tips.

1. Agent Mode in ChatGPT Atlas: Automate inside your browser

Agent Mode inside Atlas is one of the most powerful features I use. It allows ChatGPT to perform complex, multi-step tasks directly in a browser tab. In practice this means you can tell ChatGPT to research, log into accounts you are already signed into, create files, and populate spreadsheets — while you browse elsewhere.

How it works

Real example: Personal investment plan

I used agent mode to build a personal investment plan. I told it to research asset classes, suggest allocations based on my risk level, and then to generate a Google Sheet and Google Doc summarizing the strategy. The agent ran for several minutes, produced a spreadsheet prefilled with targets and review dates, and created a doc with next steps. This is the type of tedious work that used to take hours. Now it can be done accurately and in parallel with whatever else I’m doing.

Best practices and safety

2. Better memory controls: search, delete and restore

The memory feature now has searchable and manageable controls. This solves a political problem with long-running assistants: memories can become stale or incorrect. You can search memories, delete single items, sort by newest or oldest, and even ask ChatGPT to automatically manage memory for you.

How to manage your memories

When to edit or delete memory

Delete memories that are factually wrong or that you no longer want the assistant to act on. Edit memories that are partially correct but need nuance. Automatic management is convenient, but periodically auditing memories ensures the assistant’s recommendations remain aligned with your goals.

3. Hook ChatGPT to 8,000+ apps with Zapier and MCP

If you want to supercharge ChatGPT, connect it to external apps. The easiest and most flexible path is Zapier, which exposes thousands of apps. You can add a custom MCP (Model Connector Protocol) to ChatGPT and register Zapier as a tool. Once integrated, ChatGPT can send emails, create calendar events, post to Slack, push CRM updates, and more — all triggered from chat or an agent workflow.

Step-by-step integration summary

  1. Open ChatGPT settings and go to Apps and Connectors.
  2. Choose Advanced Settings and enable Developer Mode.
  3. Click Create to add a custom tool and select Zapier.
  4. In Zapier, go to mcp.zapier.com and create a new MCP server for ChatGPT.
  5. Copy the server/token values from Zapier and paste them into ChatGPT’s custom tool fields.
  6. Authorize the connection and enable the new tool in ChatGPT.

What this unlocks

Once connected, type @Zapier in ChatGPT to trigger Zaps, or let an agent call Zapier actions during a run. You effectively give ChatGPT the ability to read and write across systems like Gmail, Facebook Ads, Shopify, HubSpot, Salesforce, and thousands more without building a custom API integration.

Examples

4. Inline ChatGPT in Atlas: edit anything in your browser

Atlas now offers inline assistance inside web apps. Highlight text inside Google Docs, Gmail, a CMS or any webpage and click the little yellow dot that appears. That becomes a ChatGPT shortcut. You can ask the assistant to rewrite a hook, optimize an email subject, or adjust tone to match your voice and memory.

How to use it

Why this is a game changer

This takes ChatGPT from a separate tab back into the context where you are working. It reduces friction for small edits, streamlines content production, and keeps the assistant aware of the exact text it is modifying.

5. Add ChatGPT into Slack for real-time workflows

Bringing ChatGPT into Slack makes the assistant available where teams already communicate. You can add ChatGPT through the Slack Marketplace and the integration will walk you through permissions and use cases.

Use cases inside Slack

How to install

  1. Go to slack.com/marketplace and search for ChatGPT or the OpenAI app.
  2. Follow the install flow to add it to your workspace and grant necessary permissions.
  3. Test a few prompts in a private channel to validate behavior before rolling out to the team.

6. Build custom agents on platform.openai.com/agent-builder

OpenAI’s Agent Builder allows you to create specialized AI agents with tailored behaviors, actions, and permissions. This is where you design a version of ChatGPT that acts like a domain-specific assistant — for sales, hiring, support or internal automation.

Capabilities of custom agents

Practical agent examples

7. Supercharge agents with MCP connectors including Zapier

To make agents truly useful you must attach real-world tools. Agent Builder supports MCP connectors. Add Gmail, Outlook, PayPal, HubSpot, Square, and most importantly Zapier, to expand reach to thousands of apps.

How to connect tools

  1. In the agent builder, click Add and choose MCP connectors.
  2. For Zapier, enter your Zapier API key or follow the MCP setup steps.
  3. Grant permissions for the agent to perform specific actions (for example: view calendar, send email, create records).
  4. Test the agent in a sandbox environment before allowing it to perform live actions.

Why Zapier matters again

Zapier acts as a universal adapter. By connecting Zapier to both ChatGPT and your agent, your custom agent can orchestrate multi-step workflows across systems without additional engineering. That means you can prototype automation faster and then refine as you measure outcomes.

8. Advanced voice, camera and recording: bring reality into the model

ChatGPT’s multi-modal features have practical uses beyond novelty. On mobile, Advanced Voice plus the camera lets you show ChatGPT what you see. On desktop, the recorder captures audio from meetings and phone calls.

Mobile camera and voice

Desktop recording

The desktop recorder captures meeting audio. You can record calls and meetings, send the audio to ChatGPT, and receive a summary, action items and next steps. This is a huge time-savings for note-taking and follow-up.

Privacy and consent

Always inform participants when recording, and get explicit consent before sending meeting audio to ChatGPT. Treat the audio as sensitive data and follow your organization’s compliance requirements.

9. Scheduling and recurring tasks inside ChatGPT

ChatGPT can now schedule recurring prompts and deliver outputs on a cadence. This turns the assistant into a lightweight scheduler and content generator.

How to create a schedule

Examples of scheduled automations

Combine schedules with connectors

When you combine schedules with Zapier or agent capabilities, the possibilities expand — for example auto-generating weekly reports and publishing them to a shared drive, message, or dashboard without any manual intervention.

10. Explore GPTs: reuse community-built assistants

The GPTs marketplace is a hidden goldmine. Instead of building from scratch, search the marketplace for prebuilt GPTs tailored to specific tasks like YouTube scripts, ad copy, customer support templates or niche industry assistants.

How to choose a GPT from the marketplace

Why use community GPTs

These are often trained with domain-specific prompts and system instructions that would otherwise take you time to design. They can accelerate your content production, and they are a great learning resource to see how experienced creators structure prompts and system messages.

Practical automation workflows you can implement today

Below are a few end-to-end automation examples you can set up this afternoon using the features above.

Workflow: Weekly analytics report emailed every Monday

  1. Create a Zapier Zap that fetches metrics from your analytics provider and outputs a CSV.
  2. Connect Zapier via MCP to ChatGPT.
  3. In ChatGPT create a schedule named Weekly Analytics that runs every Monday.
  4. Prompt the schedule to draft a summary email and attach the CSV link. Have it push the email via Gmail connector.
  5. Test and iterate until the email format and metrics match stakeholder expectations.

Workflow: Candidate screening assistant

  1. Build an agent in Agent Builder with a persona of a technical screener.
  2. Attach the Gmail connector and your ATS via Zapier.
  3. Give the agent a task to read resumes submitted to a hiring inbox, summarize suitability, and suggest interview questions.
  4. Use schedules to run the screening job daily and send flagged candidates to the hiring manager.

Workflow: Content production assistant

  1. Find a GPT in Explore that specializes in YouTube scripts or create your own agent with your channel voice.
  2. Use Atlas inline editing to draft hooks and have ChatGPT rewrite them directly within your script document.
  3. Schedule a daily prompt to generate social snippets and push them to your social management tool via Zapier.

Common pitfalls and how to avoid them

Here are typical mistakes people make when they first automate with ChatGPT and how to avoid them.

Case studies: quick snapshots

Small organizations and creators can gain outsized benefits from these features. Here are two compact case studies.

Creator case study

A YouTube creator I worked with automated script drafting and social snippets. They used a prebuilt GPT for long-form scripts, Atlas inline edits to tune hooks, and a Zapier schedule that pushed daily social captions to Buffer. Time to publish dropped by 60 percent and consistent branding improved view retention by 8 percent in the first month.

Small business case study

A small ecommerce store connected ChatGPT to Shopify and Slack via Zapier. An agent monitored low inventory, created purchase orders, and sent a Slack alert with a one-click approval option. Stockouts decreased 40 percent, and the owner regained two hours per day previously spent on manual inventory checks.

Call to action

Start by picking one task you do every day and try to automate it using the tools in this guide. If you want a fast win, connect Zapier via MCP and create a scheduled task that runs hourly or daily. Build, test, and iterate. If you want help with specific workflows, leave a comment describing your use case and I will suggest a blueprint to get you started.

How do I connect Zapier to ChatGPT using MCP?

Enable Developer Mode in ChatGPT settings under Apps and Connectors, create a custom tool and select Zapier. In Zapier go to mcp.zapier.com, create an MCP server, copy the server/token values and paste them into ChatGPT. Authorize the connection and then you can call Zapier via @Zapier from within ChatGPT or agents.

Can ChatGPT perform actions while I browse other tabs?

Yes. Agent Mode in Atlas can run in a dedicated tab and continue executing tasks while you work in other tabs. It can perform research, create documents, and populate spreadsheets as long as you give it the correct permissions and context.

Is it safe to record meetings and send audio to ChatGPT?

Recording and sending meeting audio to ChatGPT is powerful for summaries and action items but requires consent and compliance checks. Inform participants, get explicit consent, and ensure the content does not violate privacy policies or regulatory requirements. Treat recordings as sensitive data and manage access carefully.

How do I control or delete memories that ChatGPT stores?

Go to Personalization and click Manage next to Memory. You can search memories by keyword, delete incorrect items, sort by newest or oldest, and enable automatic memory management. If memory changes break behavior, use conversation history to restore a previous version.

What are some quick automations I can set up in under an hour?

Three fast automations: 1) Schedule a daily summary of new emails sent to your inbox using a Zapier fetch and a ChatGPT scheduled prompt. 2) Create a content snippet generator using a prebuilt GPT and schedule social captions. 3) Build a meeting recorder that uploads audio to ChatGPT for an automatic summary and action items. All three can be prototyped in under an hour with basic permissions and testing.

Where can I find prebuilt GPTs for specific tasks?

Open the Explore section under GPTs and search for keywords such as YouTube scripts, Facebook ads, or customer support. Look for GPTs with high usage counts and user ratings. Test them privately and refine prompts to match your style before using them in production.

How do I ensure my agents do not unintentionally perform harmful actions?

Implement permission boundaries, sandbox testing, and human approval gates. Limit agent access to read-only where possible, require manual confirmations for destructive actions, log all agent activities, and use rollback strategies such as backups and version histories for generated content.

Can I monetize a custom agent I build?

Yes. Agents built with the agent builder can be shared or monetized depending on OpenAI’s distribution options and your own licensing. Be sure you comply with platform terms and consider data privacy, support, and maintenance responsibilities before offering a paid agent.

Final thoughts

ChatGPT now sits at the intersection of automation, integrations and personal productivity. From agent-driven browser automation to connecting thousands of apps with Zapier, to building custom agents and leveraging mobile camera features, these hidden settings are the real leverage points. Use them responsibly, focus on high-value repetitive tasks first, and iterate. Once you get comfortable, ChatGPT will stop being a tool you use and become an assistant that works for you.
