AI-Native Tool Development

Build specialized IDEs, modeling environments, and configurators with AI that truly interact with your domain—not just a generic chat bolted onto the side.
We help you create AI assistants deeply integrated into domain-specific workflows: connected to your data sources and tool capabilities via modern protocols like MCP and A2A, aware of your processes, and designed for how your users actually work.

Whether you build on Theia AI, VS Code, or custom platforms, we bring the expertise to make AI a natural part of your tool.

Let's discuss your AI-native tool project

Domain-Specific AI Integration

Generic AI can’t trigger workflows, invoke your tool’s capabilities, or interact with domain-specific systems. We build AI integration that goes deeper:

Connected to your data and tool capabilities via APIs, MCP, Skills, or custom integrations
Aware of your domain through context engineering and retrieval mechanisms aligned with your use case
Embedded in workflows with AI actions triggered at the right moments, not just in a chat sidebar
Agentic behavior for complex tasks and multi-step processes
Systematically evaluated with benchmarks that track quality and validate behavior across model migrations

The result: AI that helps users accomplish real tasks in your specific domain.

Platforms & Technologies

We’re platform-pragmatic, selecting technologies that fit your requirements:

Theia AI — Maximum control and customization. Open-source, vendor-neutral, fully transparent. As creators of Theia AI, we bring deep platform expertise.
VS Code Extensions — Broad reach and familiar environment for AI-enhanced extensions, optionally reusing Copilot.
Custom Platforms — AI integration into custom tool stacks, web-based tools, or existing applications.
LLM & Protocol Selection — We help you choose the right language models and communication protocols (MCP, tool calling, Skills).

We recommend what fits your needs, not what fits our portfolio.

What We Build

We develop AI-native tools across domains:

Domain-specific AI assistants embedded in specialized IDEs, modeling environments, and configurators
AI-enhanced graphical editors with intelligent suggestions for modeling and design (including Eclipse GLSP-based tools)
Code editors with specialized agents for your technology stack or domain language
Form-based tools with conversational AI for guided data entry and configuration
Agentic systems that handle complex, long-running tasks autonomously—with fine-tuned APIs enabling the AI to interact with your tool’s full capabilities

Context Engineering & Management

Effective AI integration requires more than connecting an LLM—it requires engineering what context the AI receives and how it interacts with your tool. We design context architectures that make AI effective in your domain:

Context retrieval strategies that provide relevant information at the right moment—from user selections and open files to project-wide knowledge and external data sources
Dynamic tool capabilities that adapt based on task context—enabling, disabling, or configuring tools depending on what the user is working on
Subagent architectures with specialized agents for different tasks, each with focused context and capabilities tailored to their responsibility
Prompt engineering and management with structured prompts, system instructions, and few-shot examples that encode domain knowledge
Context window optimization ensuring critical information fits within model limits while maintaining coherence across complex tasks

Getting context right is often the difference between AI that impresses in demos and AI that delivers in production.

Continuous AI Improvement

The journey with AI is continuous and evolving. Beyond implementing AI solutions, we help you set up systems for ongoing improvement:

Evaluation mechanisms to measure AI quality and identify improvement opportunities
Feedback loops allowing the AI to self-correct on the fly and enhance its capabilities incrementally
Privacy and security guidance ensuring your AI integrations are compliant with data protection requirements
LLM independence designing architectures that can switch providers as needs evolve

This ensures your AI solutions remain effective and can adapt as models, requirements, and usage patterns change.

Full Control When You Need It

For organizations where control matters—data sovereignty, compliance, vendor independence—we help you architect solutions that provide three dimensions of control:

UI Control: Design the AI experience that fits your tool. Embedded chat, inline suggestions, custom widgets, or entirely new interaction patterns. Your tool, your design.
Data & Prompt Control: Full visibility into what context goes to the LLM and how prompts are constructed. No hidden data flows, no opaque processing.
LLM Control: Choose cloud providers, self-hosted models, or fully local deployment. Switch providers as needs evolve without rebuilding your integration.

Theia AI provides these capabilities out of the box, but we can architect similar control on other platforms when requirements demand it.

What Our Customers Say

“Right from the start, we were impressed not only by the enormous expertise available at EclipseSource. This coupled with an exceptional degree of reliability and outstanding quality in the result is a combination that is rarely found in this form.”

Heinrich Steininger

CTO, Logi.cals GmbH

“EclipseSource is a trustful and reliable partner, delivering fast and high-quality results – It is fun to work this way!”

Maximilian Ost

Product Field Architect, ETAS GmbH

“I would estimate that we are advancing the project around - just as a guess - 4 times as fast thanks to the support and input from EclipseSource.”

Patrick Vale

Crossref

“This was the first time we engaged and worked with EclipseSource and it turned out to be a very positive experience. All agreed milestones were met, any problems identified were fixed in a timely manner, and all interactions were prompt, friendly, and professional. We were kept regularly informed about the progress made and given access to early versions for testing which made for a very smooth path to the final product.”

Manuel Mall

Senior Applications Developer, Synergy

“The EclipseSource consultants have a keen understanding of both the technical and business aspects of the Eclipse platform. […] I would estimate that in a few short days we’ve saved manifold our investment.”

Thomas Tik

Allianz

“I would like to thank you and your team once again for the RAP technical support provided to our project. I am very pleased with the results, which I can largely credit to the maturity of the Rich Ajax Platform (RAP). It is an excellent product and I can recommend it today as a complete solution.”

Ingo Mohr

“Yoxos Enterprise streamlines provisioning for our development team of over 200 users. It improves reliability of thetool environments for our teams and reduces development time. We have just renewed our subscription for another year.”

Frederic Mockel

EnBW, Energie Baden-Württemberg AG

“As a CEO getting his company up to speed on Eclipse I needed to provide my CTO and technical team with expert support as they explored what is a new technology for us.”

Oliver E. Cole

OCSystems

“It seemed too good to be true - that a small UI team of 6 people could develop one code base, with identical features and bugs, for an application deployed on the desktop and web. But this was the case.”

Paul Petershagen

CTO, Vitaphone GmbH
