MDLR LIMITED

What MDLR LIMITED does

MDLR Limited is a London-based software company founded in 2023 that has developed MDLR Reviewer, an open-source framework designed to transform unstructured feedback—including notes, comments, and disconnected ideas—into real-time, AI-driven summaries. The framework is delivered as a modular JavaScript/React package ecosystem consisting of two npm packages: @mdlr/project, which manages project notes, integrates with a Supabase backend, and generates AI summaries via a backend API endpoint; and @mdlr/ui-kit, which provides React UI components such as Panel, NotesPanel, and SplitPane. AI summarization is implemented via OpenAI's ChatGPT API through a GenResultService, and end users supply their own Supabase database and OpenAI API key, meaning MDLR does not host or store user data on its own infrastructure.

The company's target users are developers and collaborative teams who deal with scattered, unstructured feedback across tools such as 2D/3D canvases, whiteboards, and project management platforms like Jira and Monday. The site tagline positions the product for the 'Built Environment' (architecture/construction) sector alongside general personal-note and collaborative workflows. The alpha version was released on December 16, 2024, with modules distributed via GitHub and NPM under the MIT License. Distribution is entirely self-serve via GitHub and the NPM registry, and the go-to-market motion is community-led, product-led growth focused on gathering developer feedback.

MDLR has not yet established a commercial revenue model. The framework is free to use, modify, and redistribute under MIT, including for commercial use, and no paid tier or pricing has been announced. The company has 1–10 employees, is privately held with no disclosed funding rounds or external investors, and is led operationally through founder Eli Beaumont's blog and documentation channels.

Core offering

MDLR provides an open-source AI framework that transforms unstructured feedback (notes, comments, ideas) into real-time, auto-updating AI-driven summaries. Delivered as a modular JavaScript/React package ecosystem distributed via GitHub and NPM, it integrates with React/Next.js frontends, Supabase backends, and OpenAI's ChatGPT API to organize scattered project data into actionable insights for both personal note-taking and collaborative built-environment workflows.

Product overview

MDLR is an open-source framework delivered as a modular JavaScript/React package ecosystem. The core offering consists of the MDLR Framework itself, supplemented by two npm packages: the @mdlr/project package handles project management, Supabase integration, and AI summary generation via backend API, while the @mdlr/ui-kit package provides React UI components (Panel, NotesPanel, SplitPane) for frontend visualization. Users combine these packages with their own Supabase backend and OpenAI API key to build feedback analysis workflows.

Partnerships

Three partnerships are on record, tiered core.

• SupabasecoreTechnology or IntegrationSupabase is used as the recommended backend database solution for MDLR. The documentation provides example setup for Supabase with a schema for storing summaries, project data, and user notes. Supabase provides the backend infrastructure for managing projects and feedback buckets.
• OpenAIcoreTechnology or IntegrationMDLR integrates with OpenAI's ChatGPT API for generating AI-powered summaries. The GenResultService in the framework uses the OpenAI API key to process notes and generate dynamic summaries based on user prompts.
• React/Next.js EcosystemcoreTechnology or IntegrationMDLR is designed for seamless frontend integration with React and Next.js applications. The @mdlr/ui-kit package provides React components including Panel, NotesPanel, and SplitPane for building user interfaces.

Direct peers

• Haystack (deepset): Open-source NLP framework for building production-ready summarization, search, and RAG pipelines. Overlaps with MDLR on the developer-tool positioning and the summarization use case, though Python-first rather than JavaScript-first.
• LlamaIndex: Open-source data framework for connecting LLMs to external data sources and producing summaries/queries. Comparable to MDLR in that it enables developers to turn unstructured content into AI-driven insights via a Python/JS framework distributed through package managers.
• LangChain: Open-source framework for building LLM-powered applications. Directly comparable to MDLR as a developer-facing AI framework that abstracts OpenAI/Anthropic model calls behind a structured API — same target buyer (application developers) and same architectural pattern.

Others

• Supabase: Backend-as-a-service provider that MDLR explicitly recommends as its reference database layer. Included as an ecosystem peer because MDLR's adoption and developer experience are tightly coupled to Supabase's growth and pricing.
• OpenAI: Provider of the ChatGPT API that powers MDLR's GenResultService. Included as a critical infrastructure/enabling peer because any change to OpenAI's pricing, capabilities, or terms directly determines MDLR's cost structure and feature set.

Broad incumbents

• Vercel AI SDK: AI development toolkit from Vercel, the company behind Next.js. Highly comparable given MDLR's Next.js/React stack dependency; competes for the same developer mindshare around AI app development on the Next.js platform.
• Notion: Productivity platform with native AI features including meeting/notes summarization. Comparable to MDLR as a broad incumbent that has shipped AI summary features overlapping with MDLR's core value prop, though within a much wider product surface.

Emerging players

• Mem.ai: AI-native notes and knowledge management product with auto-organization and AI summaries. Overlaps with MDLR's personal-notes and AI-summary use case but is consumer-facing rather than a developer framework.
• n8n: Open-source workflow automation platform with growing AI/LLM node support. Comparable to MDLR in targeting technical users who want to orchestrate unstructured content into structured outputs, with partial overlap in feedback/intake workflows.
• Flowise: Open-source UI-based LLM application builder. Comparable to MDLR as an emerging open-source tool that enables developers and teams to build AI-powered workflows with similar prompt-engineering and data-orchestration patterns.
