Announcing StackChat - the most advanced API Assistant

Introducing StackChat: The AI Copilot Built for API Integrations

API integrations form the foundation of B2B SaaS and enterprise automation, yet integration processes remain slow, opaque, and often frustrating.

StackOne created StackChat to address this — an AI copilot developed and refined by integration specialists over the past year.

Integration complexity, unclear API documentation, debugging difficulties, and time-consuming research create significant friction. StackChat eliminates these obstacles by enabling streamlined API-based integrations.

The platform uses a proprietary dataset covering hundreds of enterprise SaaS APIs, combined with specialized scrapers and parsers for API documentation, featuring continuous feedback mechanisms enhancing accuracy. It operates through a multi-model mix of leading AI systems.

StackChat demonstrates superior accuracy compared to prominent language models for integration scenarios. At StackOne, internal usage over nine months produced a 50% reduction in integration build time.

Rather than providing generic responses, StackChat delivers precise answers with citations and context, minimizing hallucinations.

“StackChat transforms API challenges — unclear documentation, complex debugging, endless searching — into a streamlined experience. It’s fast, outperforms any market agent for API use-cases, and is purpose-built for integration teams addressing real problems.”

— Romain, CEO at StackOne

What You Can Do with StackChat

Research Support & Feasibility

StackChat enables integration feasibility investigation with any provider in under a minute.

Example questions include:

  • “Can I list employees created in SAP in the past week?”
  • “Does SmartRecruiters have a way to send an event for when a candidate is hired?”
  • “Can I filter employees by termination date on BambooHR?”

Even for non-indexed providers, users can paste files and images to ask documentation questions or supplement existing indexed data.

Extend StackOne’s Unified API

Existing StackOne customers can enhance unified integrations — from proxy and pass-through to custom unified field mapping — using StackChat’s deeper understanding of StackOne’s unified models.

Develop Integrations In-House Faster

For organizations not using StackOne’s unified APIs, StackChat accelerates internal integration development. Custom instructions enable specification of preferred language and framework, generating ready-to-use code.

Features

StackChat incorporates established and innovative concepts for integration knowledge agents:

  • 150+ API documentation websites, Open API specifications, and additional formats (WSDL, PDFs) indexed
  • Relevant API documentation and OAS citations accompanying every response
  • Conversation history with shareable links
  • Multimodal capability supporting PDF and image uploads with prompts, plus web browsing
  • Built-in prompt instructions with customization options

A Glimpse Into an Integration Agent

StackChat represents the beginning of broader capabilities. Currently supporting faster and smarter team sales and integration building, the platform will expand throughout 2025 into a full agentic and autonomous integration builder. StackChat will progress from answering questions to fully implementing required integrations within products.

This reflects StackOne’s broader vision: making integrations a competitive advantage rather than a bottleneck.
