Credits shouldn’t
vanish in the dark.
Many AI apps sell credits that burn at a rate you can’t see. Symphony shows you the meter.

STRAIGHT ANSWERS
Before you
spend a cent.
What is Symphony?
An AI assistant that shows the most a message can cost before you send it, and the exact charge after. Your prepaid balance cannot be overspent. It is owned and operated by Apeiron Capital Inc. and is not affiliated with SymphonyAI, Inc. of Palo Alto.
Which AI writes the answers?
In the pilot, a model from xAI. Each answer names the model that wrote it.
Can I be charged more than I expected?
No. The charge for a message is never above the maximum shown before you sent it, and a message is not sent if that maximum is more than your balance.
Does it renew automatically?
No. Pilot passes and credit packs are one-time purchases.
Are the answers checked for truth?
No. Answers can be wrong. Symphony checks that an answer arrived and was within its cost limit, not that it is correct.
Who can join?
