A little curiosity
starts here.
How is a Ree different from general AI chat?
A Ree only answers from its own sources and includes citations. No relevant knowledge means no answer and no charge.
Will my knowledge become public?
New Rees are private. Public pages show the description and how many sources there are, never the full text; citations contain only relevant excerpts.
What is the difference between Plan and Pack?
Plan currently costs $10.00 for 50,000 credits that expire each cycle. An active Plan unlocks $10.00 packs of 50,000 credits that never expire, even after the Plan ends.
How are multi-Ree conversations charged?
The maximum cost is shown and reserved before sending. Each answering Ree charges 20 base credits plus its owner fee. Unused reservations are released.
