# Free .ai domain value estimator

Find out what a .ai domain is worth in seconds: auction, marketplace and brokerage estimates with likely ranges, based on publicly reported .ai sales. Value one name or a whole portfolio of up to 1,000 names.

## How the estimate works

- **Kind of name.** One word, two words, 2- to 4-letter names, numbers or invented brand names each sell at a different level.

- **Public .ai sales set the scale.** The levels are calibrated against [reported .ai sales](https://4ai.ai/ai-domain-sales-records/), from four-figure names up to Bot.ai at $1.2 million.

- **The name adjusts it.** Length, how strong and commercial the words are, letter quality, pronounceability, hyphens and digits, and lucky or unlucky numbers.

- **The sale channel sets the price.** Auction (a quick sale to investors), marketplace (a fixed-price listing) and brokerage (a negotiated sale to an end user).

## Questions

### Is the .ai domain value estimator free?

Yes. It is completely free, with no account, no sign-up and no daily limit. The same estimates are available as a free JSON API and through the 4ai MCP server for AI assistants.

### How is the value of a .ai domain estimated?

The model classifies the name (one word, two words, short letters, numbers, brandable), sets a value level from publicly reported .ai sales for that kind of name, and adjusts it for length, word strength, letter quality, pronounceability and lucky digits. It then gives three values: auction, marketplace and brokerage.

### Why are there three values?

The same name sells for very different amounts depending on how it is sold: quickly to investors at auction, at a fixed price on a marketplace, or through a negotiated sale to a company that needs exactly that name.

### How accurate is it?

It is an estimate based on patterns in public sales, good for deciding which names deserve a closer look, not an appraisal. Many large sales are private, and the right buyer can pay far more.

### Can I value many domains at once?

Yes. Paste up to 1,000 names in the bulk tab, sort by any value and download the results as a CSV file.
