Getting Access

ChatGPT is available at chatgpt.com and as an iOS/Android app. There's a free tier and paid plans. Sign up with an email or Google/Microsoft account.

For regular business use, the Plus plan (~$20/month) is worth it — you get higher limits, the most capable models, file uploads, image generation, voice mode, and Custom GPTs.

Your First Conversation

ChatGPT's interface is one big text box. Type your request, press Enter, get an answer.

Start with a context-setting message:

"I'm a small business owner. I run a 12-person commercial cleaning company in Tampa. I'll be asking you for help with client emails, scheduling, marketing, and general business questions. Reply in a friendly but professional tone."

ChatGPT will hold this context for the rest of the conversation.

How Conversations Work

Like Claude, ChatGPT remembers everything in the current conversation. You can refine, build on, and follow up:

"Make it shorter."
"Now write a version for a different customer who hasn't replied in two weeks."
"What did you mean by 'soft commit' in that paragraph?"

When you start a new chat, it forgets — unless you turn on Memory (see below).

Choosing a Model

In the model picker at the top of the chat, you'll see options. Names change as OpenAI ships new models, but the pattern is consistent:

The flagship model — most capable, best for complex reasoning, long writing, or important work.
A fast/lightweight model — quicker and cheaper, good for routine tasks.
A reasoning model — takes longer to "think" but is better at multi-step problems, careful analysis, and math.

When in doubt, use the flagship model. Switch to the reasoning model for harder problems where the first answer feels shallow.

Practical Tips for Business Use

Give ChatGPT a Role

"Act as an experienced HR manager. I need to coach a team lead through giving difficult feedback to their direct report."

Ask for Multiple Options

"Give me three different versions of this email subject line — one curiosity-driven, one benefit-driven, one urgent."

Specify the Output Format

"Write this as a table with columns for task, owner, and deadline."

Paste In Documents

ChatGPT can read content you paste directly into the chat. Long emails, contracts, meeting notes, reviews — paste and ask it to summarize, rewrite, or analyze.

Upload Files

Click the paperclip (or drag-and-drop) to attach PDFs, Word docs, spreadsheets, images, and screenshots:

Drop in a PDF contract: "What are my obligations and any clauses I should push back on?"
Upload a CSV of last quarter's expenses: "Categorize these and tell me where I'm overspending."
Snap a photo of a bill: "Explain what this is charging me for, line by line."
Share a screenshot of a confusing report: "What is this saying?"

Generate Images

Just ask: "Generate a square image for an Instagram post — a friendly photo-style image of a small bakery storefront with morning light." Adjust by asking for changes ("make it a wider angle," "add a chalkboard sign with 'open' on it").

Iterate Instead of Starting Over

If the first answer is close but not right:

"Cut it in half."
"More casual tone."
"Lose the marketing-speak."
"Add a section on our 30-day guarantee."

Almost always faster than rewriting the prompt and trying again.

Voice Mode

On the mobile app (and now in the web app for some users), tap the headphones icon to start a real spoken conversation. Useful for:

Brainstorming while you drive between job sites
Talking through a tough decision out loud
Getting feedback on a script or sales pitch by saying it
Hands-free dictation: narrate an email and have it write the draft

Custom GPTs

A Custom GPT is ChatGPT with pre-loaded instructions, business context, and even uploaded reference files. Build one for any repeat task:

"Customer email writer in our voice"
"Onboarding checklist generator for our service business"
"First-pass review of vendor proposals"

To build one: click your profile → My GPTs → Create a GPT. Walk through the prompts (the GPT itself will ask you questions to set it up). Save and use it like a dedicated assistant.

You can keep Custom GPTs private, share them with specific people via link, or share with your team if you're on a Team plan.

Memory

ChatGPT can optionally remember details about you across conversations — your business name, tone preferences, recurring projects. To enable: Settings → Personalization → Memory. To see or clear what it remembers: Settings → Personalization → Manage Memory.

Be cautious about what you tell it to remember if you handle sensitive information.

Canvas

When you're working on longer writing — a proposal, a blog post, a multi-section report — ChatGPT may open the draft in a side panel called Canvas. You can edit specific sentences inline, ask for revisions on selected sections, and watch the draft evolve without losing your place. Treat it like a co-writing surface.

Useful Prompts to Try First

Rewrite a client email:

"Rewrite this email to sound more professional but still warm: [paste]"

Summarize a contract:

"Read this contract and tell me my obligations, the other party's obligations, payment terms, exit clauses, and any unusual or risky language: [paste or upload]"

Brainstorm names:

"I'm launching a side service that does seasonal pressure-washing for residential clients. Give me 20 business name ideas — mix of professional, friendly, and clever. Avoid generic 'Pro' or 'Plus' names."

Generate a quick image:

"Generate a vertical image suitable for an Instagram Story announcing a 4th of July sale at a local hardware store. Festive but not overdone."

Voice-brainstorm a problem:

Switch to voice mode and say: "I have a key employee who's been showing up late and missing details. I don't want to lose them but the situation needs to change. Coach me through how to bring this up."

Keyboard Shortcuts

Shift + Enter — new line without sending
