LangGrant for Enterprise Data

Ask anything.
Get answers across your current production databases.

LangGrant connects powerful LLMs to your current production databases, including questions that span multiple systems, without data movement, semantic modeling, or waiting on engineering. Every query runs under column-level access control, and answers become reusable Agent Workflows your team can rerun. Works on production or a standby replica.

Supported databases

Built for enterprise SQL.

Oracle
PostgreSQL
Microsoft SQL Server

Three capabilities, one system

Context replaces modeling, pipelines, and training.

LangGrant delivers the right database context to an LLM at scale, controls what the model and your agents see, and turns every query into reusable intelligence that compounds.

01 · Scalable context delivery

Accurate answers across large, fragmented databases.

Patent-pending context chunking, context caching, and distributed scaling let LLMs work on schemas that exceed their context windows, across one database or many.

  • Single or multi-database queries
  • Automatic schema updates
  • Infers missing relationships and complex joins

02 · Controlled data access

Govern what the LLM sees and what users get back.

Role-based access at the column level, policy-aligned context, and visibility into token usage, so AI on production data stays within enterprise boundaries.

  • Column-level access (incl. PII)
  • User and agent role alignment
  • Token usage limits and visibility

03 · Reusable intelligence

Every answer becomes a reusable Agent Workflow. Stop paying the LLM twice.

The first-pass result is persisted as a structured JSON Agent Workflow, not opaque SQL. Similar questions run the saved Workflow directly, with no new tokens and no waiting. Every query also adds to the context library, so accuracy compounds with usage.

  • Massive LLM cost savings on repeat questions
  • Auditable, human-editable JSON, not SQL
  • Each query enriches future answers
  • Callable by humans and autonomous agents

From the team behind Windocks

Backed by analysts. Trusted by global enterprises.

LangGrant is the new product from the team that built Windocks. We’ve earned Gartner recognition for database CI/CD and ML, data and analytics, and we’ve shipped into regulated industries from healthcare to insurance to global retail.

How it works

A working example: the FP&A questions that fire-drill the close, answered in seconds.

FP&A teams own variance, reconciliation, and “why is this number different” questions that span ERP, billing, and CRM. Today they wait on engineering or stitch answers from three reports. With LangGrant they just ask, and the first answer becomes a persisted Agent Workflow the team and their agents can run again, edit, and audit.

01

Finance asks in plain language

No dashboards, no semantic model, no engineering ticket. Any of the questions on the left is typed directly, and autonomous agents in your finance workflows can call the same interface.

02

LangGrant delivers tuned context to your LLM

The right schema slices, relationships, and access-controlled columns from ERP + billing + CRM are assembled and sent to your chosen model. Data stays in your databases.

03

A persisted Agent Workflow is generated and reviewed

Instead of opaque SQL, the model emits a structured JSON Agent Workflow that captures exactly how the answer was computed. It is persisted to your workspace, readable by finance, editable by humans, and far more reliably modifiable by an LLM than SQL.

// Variance vs. prior forecast · persisted Agent Workflow
{
  "name": "Q-forecast variance, by component",
  "sources": ["erp.forecast", "erp.actuals", "billing.invoices"],
  "joins": [{ "on": "period, region", "type": "inner" }],
  "compute": [
    { "id": "variance", "expr": "actuals - forecast" },
    { "id": "contribution", "expr": "variance / SUM(variance)" }
  ],
  "access": { "role": "fpa_analyst", "pii": false },
  "output": ["period", "region", "variance", "contribution"]
}
04

Reuse next month, without re-paying the LLM

Next month’s variance question runs the saved Agent Workflow directly. No new token spend on a question you’ve already asked. Every saved Workflow also becomes part of the context library, so the system gets more accurate the more your team uses it.

For humans and autonomous agents Finance leaders review and edit Workflows; agents in your finance and ops workflows call the same Workflows. Reliable, governed data access for both, through one access-control layer.
Why JSON Workflows beat SQL A persisted Agent Workflow in JSON is reviewable by finance, auditable by compliance, and modifiable by LLMs far more accurately than SQL. The same artifact serves the human reviewer, the auditor, and the model.
Costs compound in your favor Every persisted Workflow is one fewer LLM call. Repeat questions, the bulk of finance work, run nearly free after the first answer, and accuracy keeps improving as the context library grows.
What’s different

No data movement. No modeling. No upfront work.

Most AI-on-data programs spend months moving data into a warehouse, naming columns, and tying questions to metrics. LangGrant delivers context directly to the LLM from the databases you already run.
