Almost every small business owner has a free AI chatbot open in a browser tab these days — ChatGPT, Claude, or Gemini. They’re genuinely useful, and they cost nothing to start. But if your goal isn’t just to ask questions and instead to actually run a business, it’s worth understanding what each free tier really gives you — and where a purpose-built tool fits.
Here’s an honest look at the free versions, from a small business owner’s point of view.
What the free tiers have in common
ChatGPT, Claude, and Gemini are all excellent general-purpose assistants. On their free plans you can chat, brainstorm, draft emails, summarize documents, and get quick answers, subject to daily usage limits. They’re the AI equivalent of a brilliant, fast generalist who will help with almost anything you ask — as long as you bring the context each time.
ChatGPT (free)
OpenAI’s ChatGPT is the one most people have tried. The free tier gives you a capable current-generation model with usage limits, web browsing, image understanding, and some image generation. It also has a personal “memory” that can carry a few details between chats.
Best for: everyday drafting, brainstorming, and quick general answers.
Claude (free)
Anthropic’s Claude is known for thoughtful writing and careful reasoning, and it’s strong at working through longer documents you paste or upload. The free tier gives you daily access to a capable model.
Best for: long-form writing, nuanced reasoning, and digesting documents.
Gemini (free)
Google’s Gemini is woven into the Google world — Search, and increasingly Gmail, Docs, and the rest of Workspace. If your day already lives in Google’s apps, it’s the most natural fit, with generous free access.
Best for: people working inside Google’s ecosystem who want AI alongside Search.
The catch for a business owner
All three are superb — but they’re built to be general. Each conversation tends to start close to a blank slate: you re-explain your business, your customers, your numbers, and what you’re trying to do. Their memory is personal-assistant memory, not a structured picture of your company. And they’re designed to answer questions, not to sit inside your operations and move the business forward.
Bizer (free)
Bizer takes a different starting point. Instead of a general chatbot, you get Miles — an AI agent built specifically to help run a small business — and on the free account you can chat with Miles as much as you like.
The real difference is memory. Miles builds a business brain: who you are, what you sell, your customers, your team, and your numbers — and he keeps it. You explain your business once instead of at the top of every chat. Because that context sticks, the advice gets sharper the more you use it.
The free account also includes things a general chatbot simply doesn’t have:
- A preliminary Bizer Score — a read on how strong your business is across Money, Customers, Work, and Management.
- The Academy and public learning content, tuned for small business.
- A $20 credit to watch Miles actually do the work — using your connected tools — before you ever pay.
Best for: owners who want an assistant that understands their business, not a fresh conversation every time.

So which should you use?
Honestly? Many owners will keep a general assistant around — they’re fantastic for one-off writing and research, and there’s no reason to give that up. But those tools answer questions about business in general. Bizer’s free account is built around your business in particular: it remembers it, scores it, and — when you’re ready — goes and does the work inside it.
The best part is that trying it costs nothing. You can build your business brain, get a preliminary Bizer Score, and see what Miles knows about your company for free, with no card required.
