Which AI writing tools can a team of 5 use?

Why don't the usage limits use the same unit?
Every vendor counts differently: Writesonic counts AI articles, Grammarly AI prompts, Rytr characters, Wordtune rewrites per day, Sudowrite credits and Copy.ai workflow credits. We never convert between them, so the calculator checks each vendor only against its own unit.
Are the prices in USD?
Yes, before tax. Where a vendor's page showed EUR to our server in Denmark we used the vendor's own USD help text (Grammarly) or marked the plan pending (QuillBot Premium).
