Models, keys and pricing

Free#

• Drafting, redlining and review, for evaluation.
• Use the free model tier, or connect your own key for Anthropic, OpenAI, Google, DeepSeek or OpenRouter, or any OpenAI- or Anthropic-compatible endpoint.
• With your own key, usage is billed by your provider under their terms.
• The free model is text-only, so attaching images needs a vision-capable model on your own key or on Pro.
• Web search and deep research in chat are Pro features.

Pro (prepaid)#

• Premium models on our keys, with nothing to configure.
• Everything is paid from a prepaid balance (your “wallet balance” in the app). We never keep a card on file or charge one automatically.
• Two things are deducted from that balance: usage, for the premium-model requests you make, and a monthly membership fee (US$5 every 30 days at the time of writing).
• Top up with crypto (BTC, ETH, USDC and more) through our payment provider. Card top-ups aren't available yet.

The monthly membership fee#

• While you're on Pro, the fee is taken from your balance once every 30 days, whether or not you used any models that month. It's taken the next time you use the app after the period ends, so your balance can go down even on a day you only open the app.
• If your balance can't cover the fee, nothing is charged and your account moves back to Free. Top up to return to Pro.
• Account → Usage & Billing shows the current fee, the date of the next deduction, and every charge to your balance.

Your API keys#

Keys you save are encrypted with AES-256-GCM at rest and scoped to your account. They're used only for your own requests.
