To First Assistant

Enterprise AI is a complex domain.
These patterns show up everywhere.

We've seen dozens of AI initiatives hit the same walls. Not because teams aren't smart — but because this stuff is genuinely hard, and the pitfalls aren't obvious until you're in them. Gustave is built around what we've learned.

The Document Dump

It seems logical: upload your docs, let the AI figure it out. But without proper chunking strategies and curation, you get inconsistent results. RAG isn't a feature — it's a discipline that takes time to get right.

The Provider Trap

You pick a provider, build around their API, and six months later a better model comes out elsewhere. Suddenly switching means rewriting everything. It's an easy trap to fall into.

The POC Gap

The demo works beautifully. Then someone asks about authentication. Multi-tenancy. Version control. Audit trails. The gap between "working prototype" and "production system" is bigger than it looks.

The Infrastructure Surprise

Every team building AI in-house discovers the same thing: the plumbing takes 3x longer than expected. Weeks turn into months. The use cases wait while infrastructure gets built.

The Security Afterthought

Access control, tenant isolation, SSO — these feel like "later" problems until compliance asks about them. Bolting security onto an existing system is always harder than building it in from the start.

The "What Changed?" Problem

Someone updates a prompt and results get worse. Which version was working? What exactly changed? Without proper versioning, debugging AI systems becomes guesswork.

Four studios.
One platform.

Start with the Core — everything you need to launch your first assistant. Add Knowledge Studio and MCP Studio when you're ready to go deeper. Each piece is independent. All of them work better together.
Gustave Core — Your Launchpad

This is where every Gustave deployment begins. Assistants Studio is your design workbench — wire up providers, author prompts, compose assistants, control who sees what. Chat is where those assistants meet your users. Together, they're everything you need to go from zero to a production assistant in minutes.

Gustave Assistants Studio

The workbench where your AI assistants take shape. Connect providers, craft prompts, compose capabilities, manage access — then publish with a click.

  • Multi-provider LLM management
  • Prompt & skill authoring
  • Assistant composition & versioning
  • RBAC, roles & project management
  • Full audit trail

Gustave Chat

Where your assistants meet the world. Real-time streaming, tool calling, RAG-augmented conversations — plus a full API so you can embed assistants anywhere.

  • Real-time streaming responses
  • Multi-turn tool calling (MCP)
  • RAG-augmented conversations
  • Rich markdown rendering
  • Assistants API for integration
Gustave Knowledge Studio

Your assistants are only as good as what they know. Knowledge Studio turns your documents into intelligent, searchable knowledge bases with proper chunking, embeddings, and vector stores — so your RAG pipeline delivers real answers, not hallucinations.

Knowledge Studio

From document ingestion to semantic search in one place. Full control over how your data is chunked, embedded, and retrieved — because RAG is a discipline, not a checkbox.

  • Document collections & file management
  • Configurable chunking strategies
  • Multiple embedding providers
  • Vector store creation & indexing
  • Semantic search API
  • Version-controlled knowledge bases

Semantic Search

Query your knowledge bases using natural language. Results are ranked by relevance, scoped to projects, and ready to feed into RAG pipelines or standalone search interfaces.

  • Natural language queries
  • Project-scoped search
  • Relevance-ranked results
  • Multi-store search
  • REST API for integration
Gustave MCP Studio

Knowledge makes your assistants smart. Tools make them capable. MCP Studio is where you give assistants the power to act — paste an OpenAPI spec, hot-load plugins, scope tools per assistant, and expose everything through the Model Context Protocol. One control plane for every integration.

MCP Gateway & Plugins

Hot-load plugins to extend your AI with custom tools. Query databases, call APIs, create tickets — or wrap multi-step business workflows into single deterministic tools.

  • Plugin architecture with hot-loading
  • Native MCP protocol support
  • Built-in auth (Bearer, API Key, Basic)
  • Dynamic configuration & tool bindings
  • Health monitoring & audit logging

API Catalog

Import any OpenAPI specification and automatically expose it as MCP-compatible tools. Turn your existing REST APIs into AI capabilities without writing a single plugin.

  • OpenAPI spec import
  • Automatic MCP endpoint generation
  • Plugin registry for sharing
  • Per-configuration access controls
  • WebSocket real-time notifications
“Like the great concierges of Europe's grand hotels — orchestrating everything behind the scenes so the experience is flawless. That's what Gustave does for enterprise AI.”
Infrastructure that works, so you can focus on what matters.

From zero to production assistant
in five steps.

Compose, don't code. Gustave gives you modular building blocks that snap together into production-grade assistants.

Knowledge Studio

Build Your Knowledge Base

Upload documents, organize them into collections, and transform them into searchable knowledge bases with proper chunking strategies — not just document dumps.

  • Support for multiple file formats
  • Intelligent chunking per content type
  • Extensible for additional formats
  • Versioned with activation controls

MCP Studio

Connect Tools via MCP

Give your assistants real capabilities through the Model Context Protocol (MCP) — the emerging open standard for AI tool integration. Query databases, call internal APIs, create tickets, search the web — anything exposed through an MCP server becomes a tool your assistant can use.

  • Native MCP support — STDIO and HTTP servers
  • Create reusable tool templates, deploy across environments
  • Built-in auth (Basic, Bearer, API Key) per server
  • Standards-based — no proprietary lock-in

  • Version snapshots on every publish
  • Real-time streaming responses
  • Rich markdown rendering
  • Full conversation history
