With Firmafakta in your AI assistant you ask for companies in your own words, for example "all construction companies in Halland with 10 to 49 employees". The assistant tells you how many there are and fetches the list when you want it.

Connecting takes a couple of minutes. You need a Firmafakta account (you can create one for free) and this address, which you copy and paste:

Try a question

• ”How many construction companies with 10 to 49 employees are there in Halland?” Ask Claude Copy
• ”Find all accounting firms in Gothenburg municipality and give me the list.” Ask Claude Copy
• ”Same again, but only the ones started in the last five years.” Ask Claude Copy

The assistant usually counts first and asks you before it fetches, so you see what the list costs in credits. They are the same credits as on the web.
