Jentic's public beta is live!

Jentic is designed to solve one of the hardest problems in agent development, which is tool use. Agents must interact with the deterministic world of software APIs through the inherently non-deterministic nature of LLMs. If you've built agents using multiple APIs, you've probably faced reliability challenges caused by bloating your agent’s context window with detailed tool definitions. This approach quickly hits performance and accuracy walls, making your agent less effective precisely when you need it to be sharpest.

At Jentic, we've pioneered Just-In-Time Tooling (JITT), a new approach that allows agents to dynamically load tools only when they’re actually needed. Imagine trying to reason through a complex coding problem: you don't want to be preoccupied trying to to constantly recall every Vim command; instead you stick a Vim cheatsheet on the wall, and you keep your attention focused on the coding problem. JITT allows your agent to do the same thing - loading tool knowledge on-demand, keeping the context window clear of unnecessary tool clutter, and maintaining its attention on planning and reasoning. Tools that are just-in-time, not-just-case. 

This Just-In-Time approach leverages the Open Agentic Knowledge (OAK) repository, our open-source catalog of thousands of APIs and workflows specifically optimised for AI use. OAK stores tools as data, not code. It does this using widely accepted open standards like OpenAPI for APIs and Arazzo for workflows. By schematising tools into widely accepted standard data formats, OAK makes agent tooling seamlessly interoperable, portable, and instantly retrievable by your agents.  OAK is the AI-native foundation for the future of agent tooling... a future in which integrations are fluid, direct and do not require assistance from intermediaries, middlemen or walled gardens. 

The shift from code-driven to data-driven tool knowledge transforms tooling integration into a retrieval problem, enabling you to build highly capable agents while benefitting from vastly improved reliability, speed and cost. This data-driven approach also enables rigorous handling of authentication, permissions and security. With Jentic, your agent taps into unlimited API operations without needing thousands of MCP servers, you just need one. It's secure, reliable, and built from the ground up for scale.

We deeply believe that this knowledge must remain open and free with no walled gardens and no tollbooths. That's why OAK is released under the permissive MIT license, ensuring universal accessibility.

Jentic is now available in public beta, ready for you to try. We'd love to hear your feedback; what breaks, what works, and what you build with it. Join our community on Discord, dive into our docs, and stay updated through our mailing list. Exciting developments like enhanced authentication and fine-grained permissions management are on our immediate roadmap.

Let’s build agents that are both capable and reliable!
