Approval workflows
Pause execution until a human approves. Configure per-tool: owner only, any member, or self-approval. Modify parameters before proceeding.

"Hey AI, I need to

Stop building internal tools. Just talk to your AI. It handles the work, generates the UI, and asks when it needs you.

Problem
Internal tools become debt the moment you ship them
Nobody wants to maintain someone else's Retool app. The original author left. The API got deprecated. And now you're stuck debugging JavaScript embedded in a drag-and-drop canvas.

What if you never had to build—or maintain—internal tools again?
The solution
What if you never had to build them?
Just tell your AI what you need. It generates the UI, fetches the data, and asks when it needs you.
Use case: Customer refund
"Process a refund for order #4521"
The agent looks up the order, checks the customer history, and generates a refund form with all the details pre-filled. You just review and approve.

Process a refund for order #4521. Customer says item arrived damaged.
Found the order. Here's the refund form:
Use case: Data analysis
"Show me failed payments this week"
The agent queries your database, displays the results in a sortable table, and lets you select rows for bulk actions. No SQL knowledge required.

Show me all failed payments from this week
Found 5 failed payments. Select rows to retry:

Use case: Reporting
"Generate this month's revenue report"
The agent pulls data from Stripe, visualizes it with charts, and asks if you want to export or share with the team. Full report, zero manual work.

Zero maintenance: Every interface is generated fresh. No dashboards to update. No forms to maintain. The AI creates exactly what you need, when you need it.
But there's more
Your AI messages you first
Like a colleague tapping your shoulder. Set triggers—cron, webhooks, events—and your agents reach out when something needs attention. You respond when you're ready.

Readable, editable code
Every tool is a JavaScript function with typed params and returns. Use context.resources to query Postgres, call Stripe, and more.
// Params: { hours: number }// Returns: { payments: Payment[] } const { hours } = paramsconst stripe = context.resources.stripe const payments = await stripe.paymentIntents.list({ created: { gte: Date.now() - hours * 3600000 }, limit: 100}) const failed = payments.data.filter( p => p.status === "requires_payment_method") return { payments: failed } 3

Zero maintenance
UI that builds itself
Forms, tables, charts, approvals—generated fresh for each task. Nothing to maintain.
Forms
Text, numbers, dates, dropdowns, checkboxes—whatever the task needs, with built-in validation.
Tables
Sortable, selectable rows. Pick one or many for bulk operations. No configuration needed.
Charts
Line, bar, pie—visualize any data instantly. No BI tool required.
Approvals
Confirm, modify, or reject. Dangerous operations require human sign-off.
Result: Your team talks. AI handles the UI. No Retool. No React dashboards.
Production ready
Built for developers. Ready for enterprise.
Fine-grained permissions
Role-based access control at the tool level. Define who can run what, and which operations require approval.
Secure database access
Connect Postgres and MySQL from your VPC. Deploy a lightweight connector, outbound-only. No firewall changes, no exposed ports.
Durable execution
Workflows survive restarts, deploys, and outages. State recovery is automatic. Long-running tasks handled gracefully.
Multi-LLM
OpenAI, Anthropic, Google. Use the right model for each agent. Switch providers without changing your tools.
Vim mode
Full Vim keybindings in the code editor. Because real developers don't use mice. Escape to normal mode, you know the rest.
