Tables, permissions, automations, and apps, built from your own AI or from a prompt. One database underneath. Your permissions. Every change logged. Works with Claude, ChatGPT, Cursor, and any MCP client.
Everything below runs on the same database, under the same permissions.
Connect any MCP client. Build tables, permissions, and automations. Read, analyze, and update records.
Describe the app, get the app, keep changing it. Real tables, real permissions.
Plain-language questions, answered from your data, only what your role can see.
Invoices, receipts, and documents become structured data on their own. Original stays on the record.
Incoming mail read, classified, and turned into tickets or records. Thread attached.
Messages from customers and field teams become records and updates. Human handoff when needed.
Granular access by role, table, and field. The AI inherits it. Included, never an add-on.
Who did what, when, human or AI. Same log for both.
We work with the frontier labs and pick the best model per task. Through MCP, you bring your own.
You don't need to prompt any of this yourself. But you can. That's the arrangement.
Off-the-shelf software makes your team bend to its fields and flows. Here the app is built from how you actually work: your stages, your fields, your approvals. Describe it, get it, change it when the process changes.
Invoices, receipts, and IDs get read on arrival. Email becomes tickets. WhatsApp messages become records. The data enters the system without anyone retyping it, and the original stays attached.
"Which invoices are overdue?" "Who hasn't submitted expenses?" Ask it in plain language and get the answer from your records. Managers stop waiting on someone to pull a spreadsheet.
A new field, a new stage, a new automation. Say it in Claude, Cursor, or the prompt box and it's live. Small changes stop piling up in a backlog until someone has a free afternoon.
CRM, forms, approvals, docs, and dashboards in the same place, on the same data. No more copying a lead from the inbox to the CRM to the spreadsheet.
Permissions by role, table, and field, applied to humans and AI alike. Finance sees bank details, support doesn't, and nobody has to remember to lock a column.
Other tools turn a prompt into a codebase. Then the codebase is yours: the database, the auth, the permissions, the backups, the bugs. Jestor turns a prompt into an app on a platform that already has all of that.
| What you get | Jestor | Other tool |
|---|---|---|
| Tables, fields, views, and automations | Changes are edits, not rewrites. | Generate code. Every change is a new generation and a new chance to break something. |
| Database, roles, and field-level permissions | Already there. The AI works inside them. | Wire up a database, auth, and permissions. Or the AI does, its way. |
| Security | SOC 2, audited annually, same perimeter for AI and humans. | Live with whatever the generated code happens to do. |
| After ten prompts | Ten tables that a builder can open and read. | One prompt gets you a demo. Ten prompts get you a codebase nobody understands. |
| When it breaks | A senior Jestor builder is on it. Or you ask the AI to fix the field, not the code. | You're the developer now. |
Build fast. Stay on something built to last.
The AI can't invent a table structure, a permission model, or an auth flow. It uses the ones that exist. What it builds is consistent with what your team already runs.
Every app, agent, and MCP client writes to the same database. No sync jobs, no "which one is right", no CSV exports to reconcile.
No deploys, no dependencies, no server. Infra, security, and backups are ours. You keep the app, we keep it running.
Build in minutes from Claude, Cursor, or a prompt. Then keep it, change it, and hand it to a team of 200 without rebuilding it properly first.
Real systems that started as a sentence in Claude, Cursor, or the Jestor prompt box.
"Vendors, their documents, review by finance and legal, approved or rejected status."
"Change requests linked to projects, with an approval step and a Slack notification."
"Invoices arrive by email, get read, matched to the vendor, and routed for approval."
"Deals by stage with value, companies and contacts, and a weekly digest of deals with no activity."
