Open Source · AI Connector Hub

The AI Connector Hub for global teams with complex enterprise stacks.

FIM One is yourSecurity Auditor

Self-hosted, open-source AI runtime. Connect Slack, Teams, Salesforce, Workday — and the systems your global platform can't reach (Feishu, WeCom, DingTalk, DM, Kingbase). Start with one, scale to full-domain orchestration. Data stays on your network.

$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 in plain English to the AI Builder. Works equally for Slack and Feishu, Workday and Seeyon, Salesforce and Kingdee. 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

Every write operation pauses for human confirmation. This is implemented as an architecture-level constraint — not a setting, not a toggle. It cannot be disabled.

Private Deployment, Data Stays On-Premises

Run the complete platform in your own infrastructure. Data never leaves your network. No third-party sees your business data. Supports air-gapped deployment.

What Can You Do After Connecting Your Systems

1

Information Aggregation

Contracts in your doc system, approvals in Slack, ledgers in spreadsheets. 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

-90% Time

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

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

read_docreviewapprove

IT Operations

-80% Latency

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

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

alertlogsnotify

Business Operations

100% Auto

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

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

Developer

+3x Speed

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

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

Open Connector Ecosystem

Connect any system with an API or database — from Slack and Salesforce to the Chinese-enterprise stack most global platforms can't reach. Import OpenAPI specs in 5 minutes, describe in plain language to AI Builder, or write a Python MCP Server for full control.
