ChatGPT Projects vs. Custom GPTs: Which One to Use When

<i>If you run a small or mid-market business in Central Florida, you've probably heard about ChatGPT's new Projects feature and Custom GPTs. But which one actually helps you get work done? Let's break it down with real examples from local businesses.</i>

Last month, a client in Winter Park called me frustrated. She runs a boutique marketing agency with 12 employees. She’d spent three hours trying to set up a Custom GPT to help her team draft social media captions. It worked okay, but then she heard about ChatGPT’s new Projects feature and wondered if she’d wasted her time.

I get it. OpenAI keeps adding features, and it’s easy to feel like you’re always behind. But here’s the truth: both Projects and Custom GPTs are useful tools, but they solve different problems. Once you know the difference, you can pick the right one and move on. No hype, just results.

What Are ChatGPT Projects?

Projects is a folder-like system inside ChatGPT that lets you organize conversations around a specific topic or workflow. You can upload files, set custom instructions, and keep all related chats in one place. Think of it as a dedicated workspace for a recurring task.

For example, a real estate agent in Lake Mary might create a Project called “Listing Descriptions.” Inside, she uploads her past listing templates, a style guide, and a list of property features. Every time she starts a new chat in that Project, ChatGPT already knows the context. She can ask “Write a description for this 3-bedroom in Heathrow” and get consistent output without repeating herself.

Projects are free with a ChatGPT Plus subscription ($20/month). You can create up to 10 Projects per account, and each Project can have it’s own instructions and files. But here’s the catch: Projects don’t remember anything from one chat to the next unless you explicitly add it. Each chat starts fresh, though it shares the same files and instructions.

What Are Custom GPTs?

Custom GPTs are like specialized mini-apps you build inside ChatGPT. You give them a name, a description, custom instructions, and optionally upload knowledge files or connect them to external tools (like a calendar or database). Once created, anyone with the link can use them, and they remember context within a single conversation.

I helped a plumbing company in Apopka set up a Custom GPT called “Plumber Assistant.” It has instructions to answer common customer questions (“How much to unclog a drain?”) and pull pricing from a spreadsheet we uploaded. The GPT also has a “personality” set to friendly but professional. The owner shared the link with his two office staff, and now they handle 60% of incoming calls without bothering the plumbers.

Custom GPTs require a ChatGPT Plus or Team subscription. You can create multiple GPTs (no hard limit, but practical limits around 50-100). They can be shared publicly or privately. And they can be published to the GPT Store, though that’s not relevant for most small businesses.

Key Differences at a Glance

Here’s the simplest way to think about it: Projects are for you and your team to organize work around a topic. Custom GPTs are for others to use as a tool, even if they don’t know how to prompt.

Let’s put it side by side:

• Purpose: Projects organize your own chats; Custom GPTs are reusable tools for specific tasks.
• Sharing: Projects are private to you (or your workspace if you have a Team plan); Custom GPTs can be shared via link with anyone.
• Memory: Projects don’t remember across chats; Custom GPTs remember within a conversation but not across sessions (unless you use external memory).
• Complexity: Projects are simple to set up (just instructions and files); Custom GPTs allow more advanced features like actions (API calls) and web browsing.
• Best for: Projects for recurring personal workflows; Custom GPTs for delegating tasks to employees or clients.

When to Use Projects: A Real Example from Oviedo

Consider a small accounting firm in Oviedo. The owner, Maria, handles tax prep for 200 clients. She uses ChatGPT to draft emails, summarize tax law changes, and answer client questions. But every time she switches topics, she has to re-explain her context.

She created three Projects: “Client Emails,” “Tax Research,” and “Newsletter Drafts.” In each Project, she uploaded relevant files (email templates, IRS publications, past newsletters). Now when she opens “Client Emails,” ChatGPT already knows her tone and common scenarios. She estimates it saves her 8 hours per month during tax season.

Projects work best when you have a consistent workflow that you repeat often. You don’t need to share it with anyone else. It’s your personal assistant that stays in its lane.

When to Use Custom GPTs: A Real Example from Sanford

A home services company in Sanford (HVAC, plumbing, electrical) has 15 field technicians and 3 office staff. The office staff spend hours answering basic questions: “What’s your service area?” “Do you offer financing?” “How much for a new AC?”.

I built them a Custom GPT called “Service Desk.” It has a knowledge base with their service area map, pricing list, financing options, and common troubleshooting steps. The office staff can type a customer’s question, and the GPT answers instantly. The owner also put the GPT link on his website as a chatbot widget. Now the GPT handles about 40 inquiries per week that would have gone to voicemail.

Custom GPTs shine when you need to give a consistent, repeatable capability to multiple people (or to the public). They’re like hiring a virtual intern who never forgets the rules.

Which One Saves You More Time?

It depends on your bottleneck. If you’re the only one doing the work, Projects will save you more time because they reduce the friction of starting a new task. If you have team members or customers who ask the same questions repeatedly, a Custom GPT will save you more time by automating those answers.

I’ve seen businesses use both together. For example, a property management company in Lake Nona uses a Project to organize their lease renewal workflows (personal to the owner), and a Custom GPT to answer tenant questions (shared with the front desk). Total cost: $20/month for ChatGPT Plus. Total time saved: about 15 hours per week across the team.

Let’s get concrete with numbers. A typical small business owner spends 5-10 hours per week on repetitive tasks that involve text: drafting emails, answering common questions, summarizing documents. Using Projects can cut that by 30-50% for personal tasks. Using Custom GPTs can cut it by 50-70% for team-facing tasks. Combined, you’re looking at reclaiming 10-20 hours per week. That’s a part-time employee’s worth of time for $20/month.

How to Get Started Without Overthinking

Here’s my advice: start with Projects. They’re simpler and you’ll see results faster. Pick one recurring task you do at least twice a week. Create a Project, upload any relevant files, write a short instruction (like “You are my assistant for drafting client emails. Keep tone professional but warm.”). Then use it for a week. Chances are, you’ll wonder why you didn’t do it sooner.

After you’ve used Projects for a month, you’ll naturally spot tasks that you wish you could hand off to someone else. That’s when you build a Custom GPT. Think of a task that takes you 30 minutes a week but that you’d pay someone $15/hour to do. That’s your first Custom GPT candidate.

Common Mistakes to Avoid

I’ve seen businesses make a few predictable mistakes. First, trying to build a Custom GPT for everything. One client in Clermont wanted a Custom GPT that could handle all customer service, sales, and scheduling. That’s too broad. Start narrow. A GPT that only answers “What are your hours?” is better than one that tries to do everything and fails.

Second, neglecting to update instructions. Your business changes. Your pricing changes. Your tone might shift. Both Projects and Custom GPTs need occasional maintenance. Set a reminder to review them quarterly.

Third, assuming they work perfectly out of the box. They don’t. You’ll need to test and tweak. Plan to spend 30-60 minutes refining your first Project or Custom GPT before it’s truly useful. That’s still less time than the hours it will save you.

Fourth, not using them at all. I meet business owners who say “I’ll get to it later.” Meanwhile, they’re spending 10 hours a week on tasks that could be automated. The best time to start was six months ago. The second best time is today.

Final Thoughts: Pick One and Go

You don’t need to master both at once. Pick the one that matches your biggest pain point. If you’re drowning in repetitive personal tasks, start with Projects. If your team is overwhelmed by common questions, start with a Custom GPT. Either way, you’ll free up time to focus on what actually grows your business.

I’ve helped dozens of Central Florida businesses implement these tools. If you want a hand, reach out. I’m based in Orlando and happy to chat over coffee.

Remember: the goal isn’t to use AI for the sake of it. The goal is to get your time back. Projects and Custom GPTs are just two tools in the toolbox. Use the right one for the job, and you’ll wonder how you ever worked without them.

Frequently asked questions

Can I use ChatGPT Projects without a paid subscription?

No, Projects are available only with ChatGPT Plus, Team, or Enterprise subscriptions. The Plus plan costs $20/month and includes up to 10 Projects.

How many Custom GPTs can I create?

There's no hard limit, but practical limits are around 50-100. Each Custom GPT can have its own instructions, knowledge files, and actions. You need ChatGPT Plus or higher to create them.

Can I share a ChatGPT Project with my team?

If you have a ChatGPT Team plan, Projects can be shared within your workspace. On the Plus plan, Projects are private to your account. For team sharing, Custom GPTs are a better option.

Which one is better for customer-facing chatbots?

Custom GPTs are designed for sharing via link, so they're better for customer-facing use. You can embed a GPT on your website or share the link with customers. Projects are not shareable externally.

Do Projects or Custom GPTs remember previous conversations?

Neither remembers across separate chat sessions by default. However, within a single conversation, both remember context. Custom GPTs can be extended with external memory using actions, but that's more advanced.

Can I use both Projects and Custom GPTs together?

Absolutely. Many businesses use Projects for personal workflows and Custom GPTs for team or customer tasks. They complement each other well.
