Common questions

What is a credit?
1 credit ≈ $0.02 of AI compute. A typical Haiku message costs ~1 credit, Sonnet ~4 credits, and Opus ~15 credits. Longer conversations with more context cost proportionally more.
Do credits expire?
No — credits never expire. Buy a pack today and spend it at your own pace, whether that's a day or a year from now.
What do I get for free?
Every new account starts with 200 free credits (a $4 value) automatically — no credit card required. That's enough for ~13 Opus conversations or ~200 quick Haiku queries.
Can I switch models mid-conversation?
Yes — the model bar at the top of the chat lets you switch between Haiku, Sonnet, and Opus any time. Each message is billed at the rate of the model used for that message.
How does the Document Knowledge Base work?
Upload PDFs, Markdown, TXT, or CSV files in the Intelligence panel. Aethyro chunks and embeds them using Voyage AI's embeddings. When you chat, Claude automatically retrieves the most relevant sections from your documents and uses them as context.
What are Agentic Tasks?
Agentic Tasks let Claude autonomously plan and execute multi-step goals — like researching a topic, synthesizing findings, and writing a report — without you having to hand-hold each step. Tasks use credits at the selected model's rate across all the steps they run.
Is there a usage cap or rate limit?
No caps. Send as many messages as your credits allow, as fast as you want. The only limit is your credit balance.
Can I get a refund?
If you've bought credits and haven't used them, reach out within 7 days and we'll make it right. Email [email protected].
