AI and tooling

Understand KilatKoding’s runtime AI features and the repository files that make it friendly to AI coding assistants.

The two AI layers in KilatKoding

KilatKoding includes two different AI layers:

• AI features for your product,
• AI coding assistant configuration for your development workflow.

AI features for your product

Available routes

Route	Purpose
/api/ai/chat	Streaming chat
/api/ai/generate	One-shot text generation

Core files

File	Purpose
lib/ai/provider.ts	Selects the provider and model
lib/ai/middleware.ts	Handles auth check, provider check, and usage limits
lib/ai/usage.ts	Tracks token usage and plan limits
hooks/use-ai-chat.ts	Client hook for chat UI

Supported providers

Provider	Required env	Default model as of March 19, 2026
OpenAI	OPENAI_API_KEY	gpt-4o
Anthropic	ANTHROPIC_API_KEY	claude-sonnet-4-20250514

Token limits by plan

Plan	Monthly token limit
FREE	0
BASIC	10_000
PRO	100_000
ULTIMATE	Unlimited

AI request rate limits

Plan	Request limit
FREE	10 requests per 5 minutes
BASIC	20 requests per 5 minutes
PRO	40 requests per 5 minutes
ULTIMATE	80 requests per 5 minutes

How to disable AI

If your product does not need AI yet:

NEXT_PUBLIC_ENABLE_AI=false

This keeps the repository simpler to operate without deleting the AI files or routes.

AI tooling for developers

The repository also includes context files for several AI coding tools:

File	Tool
AGENTS.md	General agent guidance and repository workflow
CLAUDE.md	Claude Code
.github/copilot-instructions.md	GitHub Copilot
.cursorrules	Cursor
.windsurfrules	Windsurf

These files exist to provide accurate context about the stack, structure, and working rules, so AI output is more relevant and less likely to suggest the wrong patterns.

When you should touch this area

• you want to enable AI features for end users,
• you want to change the default provider,
• you want to adjust token limits by plan,
• you want to update the instructions used by your team’s AI coding assistants.

When you can ignore this area

• you do not need AI features in the product yet,
• you are only changing branding, content, or marketing pages.

If you are focused on shipping the MVP quickly, AI can stay disabled at first. KilatKoding is still valuable even without turning the AI layer on.
