Describe your idea in chat and Lovable turns it into a working app or website
Describe features in everyday language and the builder creates or edits the UI, logic, and structure of a full-stack web app.
Generate front ends, backend functions, and database-backed features rather than static mockups, so the result can actually run.
Ship your project to a shareable live URL, then point a custom domain at it when you are ready to launch.
Wire the app to external APIs and services, and add AI-powered functionality such as chat, search, or generation directly inside your product.
Compress LLM prompts with one REST API call and cut token costs
Send your prompt to a single REST endpoint and receive a shorter version back as plain text, ready to pass to your model.
The vendor reports up to 40% lower LLM input cost, with a worked example showing a 45% reduction on a sample prompt.
Copy-paste examples are provided for curl, Python, JavaScript and C#, so integration takes minutes rather than days.
Wrap sections in tags to exclude them from compression or to set a specific compression ratio for that block.
