Automated reasoning that makes AI-generated software provably correct
Imandra's reasoning engine builds formal models of programs and autonomous systems, then exhaustively analyzes behavior to surface edge cases that testing and statistical models miss.
CodeLogician translates a codebase into mathematical logic and assembles a MetaModel spanning every file and dependency, giving AI assistants a complete structural context with no learning phase.
Instead of sampling inputs, Imandra decomposes state space into behavioral regions so decisions and boundary conditions are examined exhaustively and reproducibly.
Benchmarks published by Imandra show that augmenting LLMs with formal reasoning through CodeLogician closed a 41-47 percentage point accuracy gap on software-analysis reasoning tasks compared with LLM-only approaches.
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.
