I put a 25‑cent cap on every turn of my Android AI agent. Here’s why a budget beat a smarter prompt

Description and use

Kryzz AI introduces a $0.25 per‑turn cost cap to give users visibility and control over AI usage costs.

Problem

Users of pay‑per‑token AI agents lack visibility into how much a single interaction will cost, leading to unexpected bills and difficulty managing spending.

Outcome

The cost cap gives users predictable spending, reduces the need for constant monitoring, and encourages responsible use of expensive models.

Workflow

• 1. User installs Kryzz AI and supplies an OpenRouter key.
• 2. User sets a per‑turn cost cap in settings (default $0.25).
• 3. User initiates a chat or agent task.
• 4. The app displays token usage and cost per reply in the chat UI.
• 5. If the cost would exceed the cap, the agent stops or warns the user before proceeding.

Evidence

Kryzz AI is an MIT‑licensed Android app (Kotlin + Jetpack Compose) for chat, voice and agent tasks. It doesn’t run models on the phone. You bring your own OpenRouter key and the models are hosted by whichever provider you pick.

Source

Every turn has a spending limit. The default is $0.25, and you can raise it up to $2 in settings.

Source

The chat shows tokens and cost per reply, so the number isn’t hidden in a dashboard somewhere.
