What is App Solidification?
App Solidification turns the work Kro completes during a conversation into a Kro App that runs persistently on your computer.
The Problem It Solves
In a typical AI chat tool, you re-describe the same task every time, spend tokens again, and the output stays trapped in the conversation. App Solidification breaks that cycle: once Kro finishes building something, you solidify it into a standalone Kro App that runs independently of the chat.
How It Works
- Describe. Tell Kro what you need in plain language. Example: "Build me a water-drinking reminder that pops up every hour."
- Build. Kro plans the task, writes the code(no code for you), and runs it in a safe preview environment for you to check.
- Solidify. When you're satisfied, Kro saves the result as a Kro App on your machine and takes over management.
- Run. The Kro App runs going forward. It survives restarts, can launch automatically, and consumes zero credits.
(Note: if a Kro App has built-in AI capabilities like content scoring or smart recommendations, those AI calls consume credits from your account each time they run.)
What Makes a Kro App Different from a Traditional App
| Aspect | Traditional App | Kro App |
|---|---|---|
| Built by | You or a developer, as a standalone project | Kro, live during a conversation |
| Environment | You set up tools and dependencies yourself | Kro creates an isolated workspace automatically |
| Deployment | You package and install it yourself | Kro deploys locally: preview first, then save |
| Startup | You launch it manually | Kro manages lifecycle, including auto-restart after reboot |
| Monitoring | Your responsibility | Kro monitors automatically |
| Updates | Wait for a new release | Ask Kro to modify the code anytime |
Managing Kro Apps
All Kro Apps appear on the Deployed Apps page inside KroWork:
- Start / Stop each Kro App independently.
- Auto-start on boot: the Kro App launches when your computer starts.
- Register as system app: puts the Kro App in your system launcher (macOS Dock, Windows Start Menu) so you can open it without going through KroWork.
- Re-edit: go back to the original conversation and ask Kro to modify the Kro App.
- Delete: remove the Kro App entirely.
Key Benefits
Credit efficiency. A Kro App runs locally without consuming credits. You only spend credits during the initial build and later edits.
Consistent results. Same output every time. No variability from re-prompting.
Data stays local. Nothing leaves your device during execution.
Zero technical skill required. You never touch code, terminal commands, or config files.
Example Scenarios
| What you say | What Kro builds |
|---|---|
| "Make me a water-drinking reminder" | A lightweight Kro App that reminds you daily, auto-starts on boot |
| "Build a stock price monitor for AAPL and TSLA" | A Kro App showing only the tickers you care about, styled your way |
| "Create a CSV-to-chart converter" | A tool-style Kro App: drag in a CSV, pick a chart type, get a visualization |
| "Set up a resume parser that scores job matches" | A standard Kro App with file input, AI-powered scoring (consumes credits), and report output |
