The four best-known AI assistants are ChatGPT (OpenAI), Gemini (Google), Claude (Anthropic) and Copilot (Microsoft). Each company publishes benchmarks showing it's best. For the everyday work of a small business, such as drafting messages, summarising documents, answering questions and working with spreadsheets, all four are capable, and the gap between them changes every few months as new models are released.
So the useful question isn't "which is smartest?" but "which one will my team actually use, safely, where they already work?"
Start with the tools you already use
If your business runs on Google Workspace (Gmail, Drive, Docs, Sheets with your company domain), Gemini is available inside those apps, depending on your plan. Staff can summarise an email thread or draft a reply in Gmail without copying anything into another tool, which is both faster and easier to control.
If your business runs on Microsoft 365 (Outlook, Word, Excel, Teams), Copilot works inside those apps, again depending on your licence. It's especially handy for Excel and for summarising Teams meetings.
If you use neither, or mostly work on WhatsApp and phones (true of many Indian small businesses), a standalone assistant makes sense. ChatGPT is the most widely used and has an India-priced plan (₹399 a month for Go). Claude is strong at long documents and careful writing. Both have free tiers good enough to test.
How they differ in practice
These are tendencies, not fixed rules, and they shift with each release:
| ChatGPT | Gemini | Claude | Copilot | |
|---|---|---|---|---|
| Best fit | Standalone, wide range of tasks | Google Workspace businesses | Long documents, careful writing | Microsoft 365 businesses |
| Works inside | Its own app; integrations | Gmail, Docs, Sheets, Drive | Its own app; integrations | Outlook, Word, Excel, Teams |
| Indian languages | Good | Good | Good | Good |
| Business plan with admin controls | Yes | Yes (via Workspace) | Yes | Yes (via Microsoft 365) |
All four can read files, search the web and work in Hindi and other Indian languages to a useful degree. Check important non-English text with a native speaker.
A one-week test
Rather than reading reviews, test on your own work:
- Pick five real tasks from last week: a customer reply, a document summary, a spreadsheet question, a social post, a staff notice.
- Give the same instruction to two assistants (use the five-part pattern from masterclass part 3).
- Score each result: usable as-is, needs light edits, or needs rewriting.
- Note which one your team found easier to use.
The difference is often smaller than expected, and comfort matters more than a few points of quality.
Rules that apply whichever you choose
- One tool for the team, so you can set it up properly and manage access.
- Business or work accounts for anyone handling internal documents. On personal plans, switch off model training.
- No customer personal data in general assistants. See is ChatGPT safe for business data?
- Check facts. All four can make things up. See why AI makes things up.
Checklist: choosing an assistant
- Note whether your business uses Google Workspace, Microsoft 365 or neither
- Pick two assistants to test
- Run the same five real tasks through both
- Score each result and ask your team which they preferred
- Choose one for the team and set up business accounts
- Switch off model training on any personal accounts
- Review the choice in six months; the tools change quickly
