Most businesses are stuck choosing between generic SaaS that doesn't fit and custom software they can't afford. Rishon leverages AI to eliminate that tradeoff by producing custom solutions with the simplicity of SaaS, at a fraction of the cost.
Rishon can be described as AI engineer + a high-level specification language + an AI-first runtime. You create a short brief explaining what you want and hand it off to Rishon AI engineer, or to a human expert, or a team of both. They produce a specification in the Rishon language. Then, Rishon runtime executes it, just as if you found a SaaS solution that fits your needs exactly.
Contrary to traditional programming languages, the Rishon language is designed specifically for AI/human collaboration. It concisely and expressively defines the business requirements, fits well within the limited AI context window, and is easily readable by humans.
The Rishon language is designed to capture the intent, not implementation specifics. It captures the big picture, and the details, such as specific data access algorithms, the design of the user interface, RAG for LLMs, and more, are automatically deduced. As the Rishon platform evolves, the applications described in the Rishon language automatically improve with it.
Rishon embraces the continuous evolution of business applications. Its compiler verifies the consistency of each new version of the spec and validates compatibility with older versions — including data structures and relationships — so the business never suffers from migration risks.
The Rishon language and its compiler work closely with the Rishon AI engineer. The language grammar, error diagnostics, and its compilation phases are aligned with the AI's reasoning process, making the latter far more effective than the most advanced solutions on the market that produce code in traditional, human-optimized languages.
The Rishon AI engineer is specifically designed to write specifications in the Rishon language, so you don't have to, paving the way for non-technical business operators and entrepreneurs to invent new solutions in a matter of days or even hours. You start with a short explanation of what you want to build; then the AI engineer asks you clarifying questions and creates a specification in plain English that you can review and correct. Once you are happy with the spec, the Rishon AI engineer formulates it in the Rishon language and hands it off to the Rishon runtime for execution. You immediately see your creation and make changes as necessary.
The Rishon runtime executes the ontology generated from the Rishon language by the Rishon compiler, providing a correctness guarantee, leaving no room for algorithmic bugs, whether introduced by humans or AI, and requiring minimal QA effort.
The resulting applications are AI-first — built from the ground up for humans and AI to work side by side. AI agents are first-class participants: they handle phone calls, search the web, interact with third-party software, make decisions (subject to human review), while operating under strict zero-trust security protocols and guardrails set by the business owner.
The Rishon runtime comes with a built-in time machine. Every action in the application is recorded. If you discover that something went wrong three months ago — a misapplied payment, a miscategorized tenant, a wrong conclusion drawn by AI, or even a change in the business spec that shall apply retroactively — you enter the correction with that past date, and Rishon replays everything from that point forward, as if the mistake never happened. No migration scripts, no manual cleanup.
The runtime is available to clients as a traditional hands-off SaaS while it runs custom, client-specific apps. It also allows a custom app to act as a SaaS solution in its own right, with its own subscribers and monetization, allowing entrepreneurs of all walks of life to progress from an idea to a production-grade solution quickly and inexpensively.
Rishon automatically designs a user interface for its applications, based on the intent described in the Rishon language. The resulting user experience is optimized for business use cases and is tuned to the specifics of user devices (phones, tablets, laptops). For businesses that require a custom-tailored front-end, Rishon exposes a secure API, making it a natural complement to popular front-end builders such as Lovable or Replit, while also supporting manual development if desired.
Rishon exposes an API for other apps to call, and can call other apps' APIs. Also, an MCP server and a Zapier integration are in the works.
