THE NEXT EVOLUTION OF SOFTWARE

From tools we operate.
To apps that work with us.

Every generation made software more capable. Agentic apps take the next step: understanding context, adapting to the person, and carrying work forward.

What if your app could
move the work forward?

From a helpful nudge to a team of agents.
Choose a possibility. Imagine it in your product.

02 / WHAT YOUR APP COULD DO

Catch the missing piece. Before it matters.

Review the details while work is still a draft. Spot gaps, explain the fix, and give people confidence to submit.

THIS IS CORE

The engine behind
your agentic app.

We wanted agents inside the apps we already build. So we built Core: a managed platform that connects agent execution, your systems, and the experience your users see.

CoreTHE MANAGED AGENT PLATFORM

Agents & teamsReason. Use tools. Collaborate.

WorkflowsCoordinate. Wait. Resume.

KnowledgeFind context. Reference sources.

Embedded UIShow progress. Review. Act.

Your app controls access. You choose the tools, models, and approval points.

Connected to your world.

Give agents the context and tools that make them useful in your product.

Ready for the whole job.

Bring execution, knowledge, events, and human review into one flow.

Part of your experience.

Put guidance, approvals, and results where people already work.

SMALL INTEGRATION. BIG POSSIBILITIES.

Configure once.
Put agents to work.

Define your agent. Give it tools. Call run() and use the result. Core handles the execution, so your team can focus on what makes your product valuable.

Build your first agent 10–30 min first SDK resultPlanning estimate with credentials, an enabled model, and a registered tool. See setup vs. release effort.

your-first-agent.tsSERVER · TYPESCRIPT

import { Jwtson } from '@jwtson/sdk';

const core = new Jwtson();

const agent = await core.agents.ensure({
  name: 'Request reviewer',
  instructions: 'Find what needs review.',
  tools: ['lookup_request'],
});

const { text } = await agent.run('Review request 042.');

ensure() creates the agent and updates it when its definition changes.

Set JWTSON_API_URL and JWTSON_TOKEN on your server. The example uses a registered lookup_request tool.

BUILDING WITH CORE

What Core handles.
What your team supplies.

Core provides the agent infrastructure. Your team connects it to your product’s rules, systems, and users.

Responsibilities when integrating Core into your application
Core handles	Your team supplies
Agent execution & workflow coordination Run agents, coordinate steps, and resume work after input or approval.	Domain logic & business tools Define objectives, implement business tools, and choose which actions need review.
Progress, input, approval & result interfaces React hooks and components show progress, collect responses, and present results.	The surrounding product experience Design your pages, style the components, and decide where agents fit into the user journey.
Knowledge indexing & retrieval Index supplied content and retrieve relevant material within configured access.	Data selection & access policy Choose source material, keep it current, and configure who and which agents may use it.
Integration mechanisms & scoped context Provide the server SDK, scoped client sessions, and events; enforce Core’s configured permissions.	Authentication & business-system authorization Authenticate your users, establish their scope, and enforce permissions in your business APIs.

Your server creates a scoped client session after sign-in. Your Core API key stays on the server.

WHERE CORE BEGAN

Shaped by building Legalfy.

Document knowledge, shared context, durable work, and human review had to fit inside a real application. Those requirements helped shape Core’s standalone platform.
