The AI Tools Landscape for Small Businesses
There are hundreds of AI tools fighting for your attention, and most owners freeze trying to pick the "right" one. The truth is you can run almost everything in this course with two or three free tools. This lesson cuts through the noise so you know exactly what to open for each job — and what to ignore.
What You'll Learn
- The four general-purpose AI assistants every owner should know
- The strengths and free tiers of ChatGPT, Claude, Gemini, and Perplexity
- Which tool to reach for depending on the task
- How to start without spending a single dollar
The Four Tools That Cover 90% of Your Needs
You do not need a tech stack. You need a Swiss Army knife. These four general-purpose assistants handle the vast majority of small business work, and each has a free tier you can start using in the next five minutes.
1. ChatGPT (by OpenAI)
ChatGPT is the most widely used AI assistant and a fantastic default. It is excellent at marketing copy, emails, brainstorming, and quick drafts, and it has a friendly, approachable style. The free tier is generous; the paid plan ("Plus", around $20/month) adds image generation, file uploads, web browsing, and the ability to build Custom GPTs (covered in Module 4).
Best for: everyday writing, marketing content, customer emails, brainstorming, and learning the ropes.
2. Claude (by Anthropic)
Claude is known for thoughtful writing and careful reasoning over long documents. If you need to paste in a 25-page lease, a distributor contract, or a stack of customer feedback and get a genuinely smart summary, Claude shines. Its writing often sounds more natural and less "salesy" out of the box. There is a free tier and a paid plan in the same ballpark as ChatGPT.
Best for: long documents, contracts, detailed analysis, and polished, human-sounding writing.
3. Google Gemini
Gemini is Google's assistant, and its superpower is integration with Google Workspace — Gmail, Docs, Sheets, and Calendar. If your business already runs on Google tools, Gemini can draft replies inside Gmail and help build spreadsheets directly. It is also strong at research and handles images well.
Best for: businesses living in Google Workspace, spreadsheet help, and quick research.
4. Perplexity
Perplexity is a research engine. Unlike the others, it searches the live web and cites its sources with links, so you can verify what it tells you. When you need current facts — competitor pricing, local market data, "what permits do I need to sell food in my state" — Perplexity is the safest choice because you can click through and check.
Best for: research that needs to be current and sourced, competitor analysis, and fact-checking.
A Simple Rule of Thumb
| Task | Reach for |
|---|---|
| Marketing copy, captions, emails | ChatGPT or Claude |
| Reading a long contract or document | Claude |
| Anything inside Gmail, Docs, or Sheets | Gemini |
| Research that needs current, cited facts | Perplexity |
| Brainstorming and idea generation | Any of them |
You will quickly develop personal favorites. Many owners keep two tabs open: ChatGPT or Claude for writing, and Perplexity for checking facts.
What About the AI Built Into My Other Tools?
You will increasingly see "AI" buttons inside the software you already pay for — Canva, Mailchimp, QuickBooks, Squarespace, Shopify, Notion, Microsoft Copilot in Word and Excel. These are useful and worth trying, but they are usually built on the same underlying models you are learning here. Master the general-purpose assistants first, and the in-app buttons will feel obvious.
How to Start for Free
- Go to chatgpt.com and create a free account. This is your default workspace.
- Go to claude.ai and create a free account. Use it when you have a long document or want more polished writing.
- Go to perplexity.ai — you can even use it without an account to test it. Use it whenever you need sourced facts.
- If your business runs on Google, open gemini.google.com and try drafting a reply.
Do not overthink the choice. Pick ChatGPT, do the next lesson, and add the others as specific needs come up. The skill you are building — writing good prompts — transfers across all of them.
A Word on Cost and Privacy
The free tiers are enough to complete this entire course and run a small business for months. Upgrade only when you hit a wall — usually when you want file uploads, image generation, or Custom GPTs. We will cover privacy in detail in the final module, but the short version: never paste customer credit card numbers, passwords, or sensitive personal data into any AI tool, and check each tool's settings to turn off using your chats for training if that matters to you.
Key Takeaways
- Four general-purpose assistants — ChatGPT, Claude, Gemini, Perplexity — cover almost everything
- ChatGPT is the best all-round default; Claude excels at long documents and natural writing
- Gemini fits Google Workspace users; Perplexity is for current, cited research
- Start free, keep two tabs open (a writer and a researcher), and upgrade only when you hit a limit
- The prompting skill you learn transfers across every tool, including the AI buttons in apps you already use
