Questions

Frequently asked

What is Top Byte?
Top Byte is an independent software studio. It publishes mindb, a local-first mind map knowledge base, and ShipRGB, a multi-model AI image studio.
What is mindb?
mindb is a mind map knowledge base. Each map is a readable file stored on your computer. Maps can link to each other, show backlinks, and be searched together, and an AI assistant can read across them and propose edits that you approve. It runs on the web, macOS, and Windows.
Is mindb free?
Yes. mindb is free to use today and works without an account. Paid plans, when introduced, will be listed on the product site before anyone is charged.
Where is my data stored?
The mindb desktop app keeps your maps as files on your own computer. If you sign in and turn on sync, a copy is stored on our servers in Canada. Without an account, nothing you create is sent to us.
Do Top Byte products use my content to train AI?
No. Your content is sent to an AI model provider only when you use an AI feature, in order to produce the response. We do not use it to train models and we do not sell it.

Purchases can be refunded within 14 days without giving a reason. See the Refund Policy for details. ShipRGB has its own refund policy on its website.
