A limited free trial precedes paid plans starting at $9/month.

Open-source AI agents that pentest your app and prove findings.

Strix runs autonomous AI agents that behave like real attackers: they execute your code dynamically, explore the app through an HTTP proxy and headless browser, and surface vulnerabilities — then validate each with a working proof-of-concept instead of a static-analysis guess. It runs locally via Docker from the CLI, against a local codebase, a GitHub repo, or a black-box web target, with a hosted cloud version and GitHub Actions integration for CI.

Designs import from and export to Figma, and a generous free Starter tier needs no credit card.

AI-powered text adventure that turns your every action into an open-ended story.

AI Dungeon is an AI-driven text adventure where the model acts as a dungeon master, generating an open-ended story that responds to whatever you type — any action, any genre, with no fixed script.

AI legal intelligence that detects large-scale violations and sizes litigation before it's filed.

The core is open source under Apache 2.0.

No-code legal document automation plus AI contract drafting and review for lawyers.

Portable single-file memory layer for AI agents — no database.

Memvid stores an agent's knowledge as compressed 'Smart Frames' in a single portable .mv2 file that bundles data, embeddings, and the search index — replacing vector databases and complex RAG pipelines.
