Small businesses use AI assistants to draft emails, marketing copy and documents, summarize long material, and research topics faster. You type a request, the assistant drafts or explains, and you check and edit the result before using it. For team use, check the terms of a business plan, since they set how your data is handled and who can access shared work.
Check what your office suite already includes before buying anything: Gemini comes with Google Workspace from $7/user/mo, and Copilot Chat is free with eligible Microsoft 365 business plans.
Standalone plans have floors, with ChatGPT Business and Claude Team both from $20/seat/mo on annual billing with a 2-seat minimum, and both AI prices and usage caps get revised often. For research, the habit that matters most is handing the assistant your sources instead of asking it to remember. Working from memory, an assistant fills gaps with confident guesses, including sources that don't exist, while one working from the report, contract or page you gave it is far easier to check. For writing, keep one shared instruction file with your tone, phrases to avoid and two or three good examples, because that lifts quality more than switching tools.

Which categories a job needs is Editorial assessment; the tools, prices and dates are Verified data.
Prices are each vendor’s published entry plan, recorded from its own pricing page and dated. The example column prices a team of 10: only per-user prices are multiplied; flat and per-account prices are shown as published. Change the team size in the finder.
An AI assistant drafts, summarises and researches, and business plans keep your data out of model training.

Start with repeatable writing tasks such as email replies, product descriptions or meeting summaries, and give the assistant clear instructions and examples of your tone. Use a business plan so your data is handled under business terms, and check every output before it goes out.
Both are general AI assistants, and the fit depends on your tasks, the plan terms and the tools you already use. Try the same real tasks in each and compare the results your team gets. The table above lists the 4 AI assistant tools we track (ChatGPT, Claude, Gemini and Microsoft 365 Copilot) with verified entry prices.
There is no single answer. Test a few assistants on your own writing tasks, with your own tone and facts, and pick the one your team edits least. Always have a person check the final text.
The most common use in surveys is writing and marketing, followed by personal productivity such as summarizing and planning. See the sourced figures on this page.
We start from the job, not the product. The phrasings people search for this job (for example “ai for small business”) come from our research into how small and mid-size teams describe it. Which software categories the job takes is our editorial judgment. Every tool, entry price, billing unit and date comes from HelpCompare’s open dataset, recorded from each vendor’s own pricing page; nothing is estimated, and where a vendor publishes no price we say so. We take no affiliate commissions and publish no scores of our own. See our methodology or download the data from Open Data.
