# AI Configuration

Configure the AI Copilot's model, behavior, and API keys.

Model Settings

Mode selection: Choose between Agent, Ask, and Plan modes
Reasoning effort: Adjust how deeply the AI analyzes complex problems (for supported models)

API Keys

ProtoFlow uses its own API keys by default (included with your credits). For power users, you can optionally enter your own API keys for each provider:

Google Gemini API key
OpenAI API key
xAI Grok API key
Anthropic Claude API key

API keys are stored securely and never transmitted to ProtoFlow servers.

# Theme & Appearance

Customize ProtoFlow's visual appearance with built-in theme options.

Available Themes

Light

Clean, bright theme for well-lit environments

Dark (Black)

Pure black backgrounds, ideal for OLED displays

Dark (Blue)

Dark blue tint for reduced eye strain

Switch themes from the toolbar theme button or from Settings. Your theme preference is saved and persists across sessions.

# Credits & Billing

ProtoFlow app version 2.4.3 and newer displays new-harness AI usage in credits. Free accounts keep a message-based daily allowance; trials and paid plans receive included credit allowances and can add pay-as-you-go credits.

How Credits Work

Credit definition — Credits are the consistent AI usage unit shown throughout ProtoFlow
Request cost — Each request consumes credits based on the selected model, actual tokens, and any provider tools used; higher-cost model multipliers scale the total
Free account — 10 Basic-model and 5 Pro-model messages per day; this tier remains message-based
7-day Pro trial — 15 credits per day, with an 80-credit limit across the trial
Pro — 50 credits per day and 250 credits per rolling seven days
Max — 250 credits per day and 500 credits per rolling seven days
Component generation — After included generation units, a 1× model uses 30 credits per fresh part; 2×, 3×, and 8× models use 60, 90, and 240 credits
Usage tracking — View token and credit usage on each completed AI response
Rate limiting — When credits run low, a notification prompts you to purchase more
Credit purchase — Purchase additional credits via Stripe from the Settings panel or when prompted
