Is GreenCube unlimited?

Yes. GreenCube runs on your own computer, so there is no message limit, no credits and no monthly fee. You pay once, 9.99 EUR (US$9.99), and own it forever. It keeps working with no internet.

Is there a pro version or a more expensive plan?

No. There is one version of GreenCube and one price, 9.99 EUR (US$9.99), paid once. Everyone gets everything. A faster computer runs it faster, but it does not unlock anything, because there is nothing locked.

What computer do I need to run GreenCube?

A Windows 10 or 11 PC with about 8 GB of memory or more. Memory decides how much fits, and a graphics card decides how fast it runs. GreenCube names four kinds of machine: Seed (about 8 GB, no graphics card), Sprout (16 GB or more with no graphics card, or 8 GB with a card), Bloom (a graphics card with 8 GB or more, or a 4 GB card with 16 GB of memory), and Thrive (a card with 8 GB or more and 24 GB of memory or more).

Will it run on your PC?

Two questions. Ten seconds.

Question 1 of 2

How much RAM does it have?

RAM, not storage. Not the hard drive or SSD space.

Question 2 of 2

What graphics card or chip?

Most laptops have no separate card, and that is completely fine.

The four tiers

Your PC sets the speed. Same app, same price for everyone: €9.99 (US$9.99), once.

Seed

8 GB of RAM, no graphics card

Everything works, just slower. Chat, PDFs, photos, flashcards and PowerPoint. Images need 12 GB of RAM.

Sprout

16 GB of RAM with no card, or 8 GB with a card

Steady speed: about 10 words a second on a laptop with no card. Writes slide decks. Images and web pages tell you the wait first (images need 12 GB of RAM).

Bloom

A graphics card with 8 GB (RTX 3060, 4060, RX 6600), or a 4 to 6 GB card with 16 GB of RAM (GTX 1650, 1660)

Fast, thanks to the card: about 15 words a second on a tester’s GTX 1650, 25 on a GTX 1660 Super. Images and web pages with no waiting message.

Thrive

A graphics card with 8 GB or more and 24 GB of RAM or more

The fastest: about 40 words a second on a tester’s RTX 5060. Reads the longest chats and documents.
