Why Pay More?

Three reasons teams choose Engine over $10 autocomplete

Copilot helps you type faster. Engine ships production-ready features.

🛡️

Zero-Risk Generation

The Trust Factor

Instant Rollback — Undo any change with one command. Every generation creates a snapshot.
Self-Verifying Code — AI checks file existence, validates signatures, and lints before applying.

The Benefit: Mitigate the biggest fear of AI code gen — breaking your codebase.

🏗️

Architectural Compliance

The Consistency Factor

Shared Pattern Library — Enforce team standards. Every dev writes code that looks identical.
Context-Aware Generation — Indexes your codebase. Extends existing code, never duplicates.

The Benefit: End code drift. Maintain architectural consistency at scale.

📊

Quantifiable ROI

The Management Factor

ROI Dashboard — Track time saved, value generated, and ROI multiplier automatically.
Team Analytics — Per-user consumption. Justify the expense with data.

The Benefit: Prove value to management. The product pays for itself 120x over.

Why teams choose Engine over alternatives

"Self-verifying code?"

Engine's AI checks file existence, validates signatures, and lints output before generating. Other tools guess and hope.

"What about code quality?"

Team patterns enforce your architecture. Generated code follows your standards—imports, error handling, naming conventions—automatically.

"How do I justify the cost?"

Built-in ROI dashboard tracks time saved per developer. Show management exactly how much value Engine delivers.

"Scared of AI breaking my code?"

Every change is snapshotted before applying. One command restores everything. Safe experimentation, always.

Features

Enterprise-grade code generation

The most advanced AI coding assistant. Period.

🔬

Self-Verifying Code

Engine's AI checks file existence, verifies function signatures, and lints code before generating. No more broken imports or missing dependencies.

$ engine generate "add stripe webhook"

🔧 check_file_exists → ✓ api/webhooks.py exists
🔧 get_function_signature → verify_signature(payload, sig)
🔧 lint_code → ✓ Python syntax valid

✓ Generated 1 file (verified with 3 tool calls)

⚡

Hybrid RAG Context

95% of queries in ~1ms. Smart keyword search with semantic fallback. Fast enough for real-time coding.

⏪

Instant Rollback

Every change is snapshotted. Unhappy? One command restores your files. Safe experimentation, always.

📊

ROI Dashboard

FAQ

Frequently asked questions

What counts as a "generation"? +

One generation = one feature request, regardless of how many files it creates. "Add user authentication" is one generation, even if it creates 10 files.

How is this different from ChatGPT? +

ChatGPT gives you code to copy-paste. Engine indexes your actual codebase, generates code that fits your patterns, applies it directly to your files, and lets you roll back if needed.

Do I need to switch IDEs? +

No. Engine is CLI-first and works alongside any editor—VS Code, Vim, Emacs, JetBrains, or whatever you use.

What languages do you support? +

Engine works with Python, TypeScript, JavaScript, React, and more. The indexer understands functions, classes, API endpoints, and React components.

Is my code secure? What data do you collect? +

Only small, relevant code snippets (~20 chunks) are sent to generate code—never your full codebase. We don't store your source code, and it's never used for AI training. All data is encrypted in transit. Read our full Security & Privacy documentation →

What is "self-verifying code"? +

Engine's AI uses built-in tools to verify its output before generating. It checks if files exist, validates function signatures, and lints the code—so you get working code, not guesswork.

How does the ROI dashboard work? +

Engine tracks every generation, calculates estimated developer time saved (20 min/feature average), and shows your ROI multiplier. Perfect for justifying the subscription to management. Teams see per-user breakdowns.

What are team patterns? +

Patterns are code templates with rules your team defines. When you ask Engine to "create an API endpoint," it follows your team's exact patterns for error handling, validation, and structure—ensuring consistency across the codebase.
