What is Evenfall?
A focused AI chat client. You send messages, an AI model streams responses back, and your conversations are saved so you can come back to them. Think ChatGPT-style interface, without the clutter.
How do I sign in?
Email one-time code or Google OAuth. We don't use passwords. The OTP arrives in under a minute — check spam if it doesn't show up.
What's included in the free tier?
5 messages per day, markdown rendering, code blocks with copy buttons, full conversation history, per-conversation system prompts, and the model picker. Daily limit resets at midnight UTC.
What does Pro get me?
Higher daily message limits (tiers up to unlimited), priority on the streaming queue, and early access to new models as we add them. Paid plans are monthly subscriptions when you pay by card — they renew automatically and you can cancel anytime. Prefer crypto? You can instead buy a one-time 30-day pass that doesn't auto-renew — just re-buy when it lapses.
Can I set a custom system prompt?
Yes, per conversation. Open the gear icon in the chat header and edit the system prompt for that thread. Leave it empty to fall back to the default. Changes apply to the next message sent in that conversation.
Can I switch models?
Each conversation uses a fast frontier model, set in the settings dialog. We'll add more model options over time, surfaced through the same picker.
Do you use my conversations to train AI?
No. Your conversations are stored so you can return to them. They are not shared with the AI provider for training, not sold, and not used for anything beyond delivering the service back to you.
How do I delete my data?
Individual conversations: three-dot menu on any row in the sidebar, then Delete. Entire account: Settings → Danger zone → Delete account. Both are immediate and irreversible.
Do you offer refunds?
Paid plans are one-time purchases and generally non-refundable, but email support@evenfall.ai if something went wrong — we'll handle it.
Is there an API?
Not yet. When we ship one, it'll show up in your account settings.
