Gemini

By Google DeepMindLondon, United Kingdom6 products across 6 categories

Built for this. Sits inside Gmail, Docs and Drive, so it already has your context. Very large context windows and a generous free tier.

Free plan: Yes; Free tier with generous limits
Month to month: $4.99/mo; Google AI Plus
Billed yearly: $4.17/mo; $49.99 a year, Google AI Plus plan −16%

Watch out: Which underlying model you get varies by tier, and quality varies with it. Plus and Pro were both showing introductory offers when checked — a fraction of the price for the first three months, or a discount on the first year — so the number on the page is not the standing price, and the rows here quote the standing one.

All plans (6)

Plan	Price	What you get
Free	$0	Free tier with generous limits
Google AI Plus	$4.99/mo
Google AI Pro	$19.99/mo
Google AI Ultra	$99.99/mo
Google AI Ultra 20x	$199.99/mo
Workspace with Gemini	$14/mo

How to read this list

Two things separate these and both are on every card.

Fit

Whether a tool is built for this job, a strong fit for it, or able to do it without that being its focus.

Free plan

Whether there is a tier you can keep using rather than a trial that expires.

The order

Fit first, then a free plan, then alphabetical. There is no score, no weighting we decline to publish, and nothing on this site a company can buy.

Questions

What is the best ai for business ideas?

There is no single answer, which is why this page lists 4 rather than one: ChatGPT, Claude, Perplexity, Gemini. 4 of them are built for this kind of work rather than able to do it. Start with a free one.

Which of these have a free plan?

4 of the 4: ChatGPT, Claude, Perplexity, Gemini. Free means a real free tier you can keep using, not a trial that expires.

How was this list chosen?

By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
