Take LLMs beyond chatboxes, into your business systems

Your core data and workflows are locked in OA, ERP, finance, and approval systems. FIM One lets LLMs securely read and write to these systems and automate cross-system workflows — no architectural changes needed. Start with one system, then scale to full-domain orchestration.

$git clone https://github.com/fim-ai/fim-one.git && ./start.sh

Why Choose FIM One

The biggest barrier to enterprise AI adoption isn't model intelligence — it's that AI can't reach core business systems.

Zero-Modification System Integration

Import your system's API docs to auto-generate AI-callable tools; or describe your needs via AI conversation to create connections automatically. No custom development, no waiting on vendors.

Intelligent Task Orchestration

Agent auto-decomposes complex tasks, runs multiple steps in parallel, and self-checks upon completion — automatically adjusting and retrying when goals aren't met. One engine covers everything from fixed workflows to open-ended analysis.

Human Approval Before Sensitive Operations

For high-risk operations like data modifications or approval initiations, the system auto-pauses and sends confirmation requests via Feishu or DingTalk. Execution continues only after human approval, with full audit trail.

Private Deployment, Data Stays On-Premise

Run the complete platform in a single process with no additional infrastructure. Supports deployment on local servers and air-gapped networks, meeting data compliance requirements for government, finance, and healthcare.

What Can You Do After Connecting Your Systems

1

Information Aggregation

Contracts in OA, approvals in DingTalk, ledgers in Excel. Checking one matter used to mean logging into three or four systems. Now Agent auto-aggregates across systems and delivers complete results directly.

2

Workflow Automation

System A detects an issue → System B creates a ticket → System C notifies the responsible person. What used to require manual data transfer and follow-up across systems is now fully orchestrated end-to-end by Agent.

3

Intelligent Judgment

More than just moving data. Agent leverages LLM reasoning for analysis, comparison, and risk identification — like auto-referencing regulation databases during contract review and suggesting amendments with citations.

FIM One in Different Scenarios

Legal & Compliance

Before

Contract review requires switching between document libraries, approval systems, and group chats, taking days to complete.

After

Agent auto-extracts clauses, compares historical versions, flags risks, and triggers approvals — fully traceable throughout.

IT Operations

Before

Handling a single alert involves manually checking across four or five systems, taking at least an hour.

After

Agent auto-pulls logs, analyzes root causes, and pushes diagnostic conclusions with action buttons via Feishu.

View Full Solution

Business Operations

Before

Daily manual data exports, spreadsheet processing, and screenshot-sharing in group chats. Ad-hoc queries require manual calculation.

After

Agent generates scheduled data summaries pushed to group chats, with natural language instant queries supported.

Developer

Before

Integrating authentication, retries, and adapters for three systems could take a month of development.

After

Import API docs or use AI conversation — create a connector in 10 minutes with auto-generated Agent tools.
