How to Set Up ChatGPT

Go to chatgpt.com and click Sign Up. You can register with an email address and password, or sign in with an existing Google, Microsoft, or Apple account. Single sign on is the fastest option if you already use one of these services.

Verify your email if prompted. You will land on the main chat interface immediately after sign up. The free tier is active by default with access to GPT 5.3 and basic features.

Start with the free tier to confirm ChatGPT fits your workflow. If you decide to upgrade, go to Settings and select your plan. For most individuals, Plus at $20 per month is the right choice. It unlocks GPT 5.5, Deep Research, Codex, Agent Mode, and removes ads.

Skip Go at $8 per month unless you specifically only need higher message volume without advanced features. It excludes the capabilities (Codex, Deep Research, Agent Mode) that make ChatGPT a serious productivity tool. For teams, Business at $25 per user per month adds app connectors and security controls.

ChatGPT has a dedicated desktop app for macOS and Windows. Download it from chatgpt.com/desktop or your platform’s app store. The desktop app provides a keyboard shortcut (Option + Space on Mac, Alt + Space on Windows) that opens ChatGPT as an overlay from any application, so you can ask questions without switching windows.

The desktop app also supports voice mode and file uploads directly from your local file system. If you use ChatGPT multiple times per day, the desktop app is noticeably faster than keeping a browser tab open.

Download ChatGPT from the App Store (iPhone and iPad) or Google Play Store (Android). Sign in with the same account. The mobile app includes voice mode, camera input for analyzing images, and full conversation history synced across devices.

Voice mode on mobile is particularly useful for hands free brainstorming, dictating notes while commuting, or practicing conversations (like interview prep or language learning). The app supports background audio, so you can continue a voice conversation while using other apps.

Go to Settings (gear icon) then Personalization then Custom Instructions. This is one of the most impactful settings most users never configure. Custom instructions tell ChatGPT who you are and how you want it to respond in every conversation.

In the “What would you like ChatGPT to know about you?” field, add your role, industry, and relevant context. For example: “I am a product manager at a SaaS company with 200 employees. I manage a team of 5 and report to the VP of Product.”

In the “How would you like ChatGPT to respond?” field, set your preferences: “Be concise. Use bullet points for lists. Avoid jargon. When I ask for help writing, match a professional but conversational tone.”

These instructions apply to every new conversation, eliminating the need to repeat your context each time.

Go to Settings then Personalization then Memory. Toggle memory on if you want ChatGPT to remember facts and preferences across conversations. When enabled, you can explicitly tell ChatGPT to remember things: “Remember that our fiscal year starts in April” or “Remember I prefer tables over bullet points for data.”

View and manage stored memories at any time in this same settings panel. Delete individual memories that are outdated or incorrect. If you work with sensitive information, you may prefer to keep memory off and rely on custom instructions instead.

Go to Settings then Data Controls. Two settings matter here. First, “Improve the model for everyone” controls whether your conversations are used to train future models. Toggle this off if you discuss proprietary business information or prefer your data not to be used for training. On Business and Enterprise plans, this is off by default.

Second, “Chat History and Training” lets you disable conversation history entirely. When turned off, conversations are not saved and not used for training, but you also lose the ability to revisit past chats. Most users keep history on and toggle training off.

If you are on a Business or Enterprise plan, go to Settings then Connected Apps to link your workspace tools. ChatGPT supports 60 plus integrations including Slack, Google Drive, SharePoint, GitHub, Atlassian, and Dropbox.

Once connected, ChatGPT can reference your documents, messages, and repositories directly in conversations. For example, “Summarize the key decisions from last week’s Slack channel on product launches” or “Find the latest revenue numbers in our Google Drive finance folder.” Start by connecting the two or three tools you use most frequently, then add others as needed.

Custom GPTs are specialized versions of ChatGPT configured for a specific task. Go to Explore GPTs in the sidebar, then click Create. Give it a name, a description of what it does, and detailed instructions for how it should behave.

Useful first custom GPTs: a meeting notes summarizer (paste in raw notes, get structured action items), a code reviewer (paste code, get feedback on bugs and best practices), or a writing editor (paste drafts, get tone and clarity suggestions). Custom GPTs save you from repeating the same setup instructions across multiple conversations.
