K21 SDK

The K21 SDK has everything you need to capture end-user data, contextualize it and deliver real user value with AI.

More information: docs.kontext21.com & kontext21.com

Components:

• k21 - Core library that can be consumed by external applications
• k21-screen - A CLI tool to handle screen captures
• k21-processor - A CLI tool to handle processing of screen captures
• k21-server - A server that provides HTTP endpoints for screen capture and processing

Library Usage

The k21 library can be used as a dependency in your Rust projects:

[dependencies]
k21 = { git = "https://github.com/kontext21/k21" }

CLI Tools Compilation

cargo build

Usage

# Screen capture
./k21-screen
./k21-screen --fps 1 --output captures/

# Processing
./k21-processor --mp4 file.mp4
./k21-processor --image file.png
./k21-screen --stdout | ./k21-processor --stdin

# Server
./k21-server

Options

k21-screen

• --fps: Screen refresh rate in fps (frames per second) - default: 1

TODO k21-screen

• --output: Output directory for screenshots
• --help: Show help information
• --version: Show version information
• --format: Output format (png, jpg, etc.)
• --overwrite: Overwrite existing files
• --duration: How long to capture the screen. Eg. 10s
• --interval: Interval in seconds between captures
• --count: Number of captures to take
• --quality: Output quality (0-100)

Ideas

• processor could just be able to handle inputs without having to specify the input type
• maybe processor could handle multiple images / inputs at once
• how do we preserve the original time stamp
• add websocket support to server for real-time updates
