Choosing an artificial intelligence tool for work or business has become an economic decision, not just a technical one. With hundreds of assistants and services competing for the market, knowing how much it really costs to use AI in 2026 helps avoid surprises on your bill and allows you to compare options with better judgment.
A catalog compiled by AI Compare, which reviewed 951 artificial intelligence tools from 40 countries, offers a fairly clear snapshot of this market. The data was also cross-referenced with the official pricing pages of ChatGPT, Claude, and Google, consulted on October 15, 2026.
Half of the tools are free, but paid plans hover around $20
According to the 2026 AI Price Index, with data cut off on October 15, 478 of the 951 tools analyzed—that is, 50.3%—offer a permanent free usage plan.
Among those that do publish a monthly list price in the United States, a total of 219 tools, the median entry-level price for the most affordable paid plan is $20 per month. This figure corresponds to the cheapest paid plan with monthly billing, excluding taxes and services that are only contracted through a sales department.
What changes depending on the tool category
The price is not uniform. It varies significantly depending on what the artificial intelligence is used for, according to the table by category provided by AI Compare:
- Productivity: 284 tools, 51.4% with a free plan, median price of $19 per month.
- Development and code: 188 tools, 63.8% with a free plan, median price of $24.50 per month.
- Design and image: 119 tools, 48.7% with a free plan, median price of $12 per month.
- Content and SEO: 91 tools, 39.6% with a free plan, median price of $25 per month.
- Media and video: 88 tools, 47.7% with a free plan, median price of $20 per month.
- Audio and voice: 79 tools, 60.8% with a free plan, median price of $16 per month.
- Business and finance: 54 tools, only 33.3% with a free plan, median price of $99 per month.
- HR and recruitment: 25 tools, barely 12% with a free plan, median price of $99 per month.
- Industry, construction, and logistics: 13 tools, 7.7% with a free plan, no median price published.
- Agriculture, energy, and tourism: 10 tools, 60% with a free plan, no median price published.
Three takeaways emerge from this data. Creative and technical categories, such as design, development, or audio, offer the most free options and have the lowest entry prices. Tools oriented toward business and human resources, on the other hand, quadruple the general median, although these are categories with fewer tools, meaning a couple of high prices heavily influence the result. And in sectors like industry or agriculture, there is simply not enough information to calculate a reliable median.
ChatGPT, Claude, and Google: what the three major assistants charge
To contrast these aggregated data with reality, the official pricing pages of the three most used AI assistants were reviewed on October 15, 2026. The prices for ChatGPT and Google correspond to what is shown from Spain, in euros; those for Claude are what Anthropic publishes, in dollars.
ChatGPT (OpenAI)
The free plan has no cost. The Go plan costs 8 euros per month, the Plus plan 23 euros per month, and the Pro plan starts at 103 euros per month. OpenAI's own page warns that the Go plan, the most economical, may include ads.
Claude (Anthropic)
The free plan also has no cost. The Pro plan costs $20 per month, or $17 per month if paid annually. The Max plan starts at $100 per month. Paying for the Pro plan annually amounts to $200 upfront compared to the $240 it would cost paying month-to-month, $40 less per year.
Google AI
The AI Plus plan costs 4.99 euros per month, the AI Pro plan 21.99 euros per month, and the AI Ultra plan starts at 99.99 euros per month.
When comparing the three services, a pattern repeats: the intermediate plan for each hovers around 20 euros or dollars per month (23 €, $20, and 21.99 €), a figure very close to the $20 median detected in the full catalog of 951 tools. The highest tier for all three, meanwhile, clusters around 100 euros or dollars per month.
When there is no fixed fee: pay-per-use
Not all AI tools work with a monthly subscription. Many, especially those that integrate directly into programs or applications via an API, charge based on actual usage: number of requests and the length of the questions and answers.
To estimate this expense, AI Compare has developed an API cost calculator. It is worth noting that its figures are based on the public price list of OpenRouter, so they may differ from the price charged directly by the company that created the model. It serves to get an idea of the budget, not as an exact invoice.
Where the analyzed tools are from
The same index measured the headquarters of the artificial intelligence providers. North America accounts for 387 of the 951 tools, Europe for 174, and Asia for 161. It should be noted that only 735 of the 951 tools have a verified country of origin, so this geographical distribution describes what has been verified and not the entire catalog.
Recommendations before paying for an AI
- Start by testing the free options: if half the market offers them, it makes sense to test them before taking out your credit card.
- Add up the total cost before subscribing to multiple tools at once. Three subscriptions of about $20 per month equal $60 per month, when often one is enough.
- If you decide to pay, check if there is an annual billing option, which is usually cheaper, and check if the most economical plan includes advertising.
- If the use is for a business, always ask for the specific price. In categories like finance or human resources, the median skyrockets to $99 per month, and in other sectors, there is not even a public price.
