Understanding Credits and Usage
How BrainTube credits work, what actions cost credits, and how to manage your usage.
BrainTube uses a credit system for AI-powered features. Here's how it works.
What Are Credits?
Credits are the currency for AI operations in BrainTube. Every AI-powered action (enrichment, chat, search, quiz generation) costs a small number of credits.
What Costs Credits?
| Action | Credit Cost | Description |
|---|---|---|
| Save & Enrich | ~2 credits | Saving a new item with AI enrichment |
| Brain Chat | ~1 credit | Asking a question to a Second Brain |
| Quiz Generation | ~1 credit | Generating a knowledge quiz |
| Deep Search | ~1 credit | Running a graph-enhanced search |
| Summary Generation | ~1 credit | Generating an AI summary |
Free Tier
All new users receive free credits to get started. The free tier includes enough credits to save and enrich 10-20 items, have several brain chat sessions, and try the Knowledge Playground.

Tips to Optimize Usage

- Use keyword search for simple queries (doesn't cost credits)
- Star important items to avoid re-searching for them
