FOUR AUTONOMOUS MODULES
Everything your repositories need on every push and pull request.
Smart PR Summarizer & Labeler
Automatically analyzes diffs on every opened or updated Pull Request, posts a structured file walkthrough, flags breaking changes, and applies semantic GitHub labels.
Secret & API Key Guardian
Scans every commit and PR diff in real time for leaked Gemini/GCP keys, GitHub PATs, OpenAI/AWS credentials, and private keys before they merge to main.
Auto-Doc & README Updater
Detects new environment variables, route changes, or CLI flags in code changes and drafts ready-to-commit README.md and API doc updates.
First-Time Contributor Welcomer
Recognizes first-time contributors opening their first PR or issue and posts a context-aware, repo-tailored welcome guide.
SECURITY & ARCHITECTURE
Engineered for maximum security, zero subscription fees, and full repo control.
AES-256-GCM Key Vault
Your Google AI Studio API keys are encrypted server-side with AES-256-GCM and a unique 96-bit IV + authentication tag before touching Firestore. Plaintext keys are never sent back to the client.
Multi-Key Failover Rotation
Paste 2, 3, or more Gemini API keys separated by commas (`key1, key2, key3`). If Key #1 hits a rate limit on a busy PR day, Syntiox Guard automatically fails over to Key #2 in milliseconds.
Per-Repo Feature System Prompts
Alongside our built-in core prompts and your global instructions, you can define custom system prompts for each individual feature on each specific repository.
