Leemer Group brings together the work I have been building since 2023: Leemer Chat, Leemer Labs, Critique.sh and DáilDex. Four products, each with its own identity, brought together by a shared approach to engineering.
The name gives that work a home. It also makes our direction clearer. We build tools that help people use intelligence, develop software and understand complex information. We want those tools to be useful enough to become part of someone's day, and reliable enough to deserve their place there.
February 2023: Leemer Chat
Leemer Chat was first released in February 2023. It began with a practical question: how do you make increasingly capable AI models useful to the person sitting in front of them?
A model is only part of that answer. The interface matters. So does the ability to carry a conversation forward, work with different models and move from a question into something you can actually use. Research, writing and coding belong in the same working context more often than product categories suggest.
That early release is where this story starts. Leemer Chat has continued to evolve since then. The workspace and later releases are chapters in that development, rather than the beginning of the product's history.
The principle remains straightforward: advanced AI should be accessible through a considered place to work.
Mid-2025: Leemer Labs
Leemer Labs launched in mid-2025. It gave a clearer focus to the work underneath the interface: training, fine-tuning, evaluation, inference and the infrastructure needed to run intelligent software.
Through this work, I have worked with a range of companies and AI experts on model training and fine-tuning, and explored early models from providers including Z.ai, Moonshot AI and OpenAI. Those experiences have been useful for a simple reason: the differences between models become much clearer when you have to make them work on a real task.
Our early testing has included Z.ai’s GLM-5.2, Moonshot AI’s Kimi-K2.6 and OpenAI’s GPT Cyber models. Working with early models gives us a closer look at their behaviour on the tasks we build for.
Trying a new model is the start of an investigation. What data does the task need? What should an evaluation measure? Where does the model fail? What does a useful deployment cost to operate? When would a smaller model, an adapted model or ordinary software be the better choice?
Leemer Labs is where we work through those questions. Its model development and research, including the Born programme, connect experimentation with documented releases and infrastructure people can use.
April 2026: Critique.sh
We launched Critique in April 2026. It grew out of a problem that became harder to ignore as coding agents became more capable: producing a change and establishing that the change is sound are different jobs.
An agent can write code quickly. Someone still has to examine the intent, reproduce a failure, run useful checks and decide whether the result is ready. That work needs evidence. A confident summary is not enough.
Our usage figures now cover hundreds of millions of lines of code reviewed and billions of tokens processed since launch. We track those separately: lines of code describe the material reviewed, while tokens describe the model processing involved.
The standard that matters is what a review gives the person making the next decision: a concrete finding, a reproduction where possible, the checks performed and a clear account of what remains uncertain.
Today, Critique includes distinct tools for that work. Critique Code is the coding harness, with implementation, review and repair in its workflow. The Critique CLI gives an existing agent or developer an independent way to examine local changes and receive a structured handoff. They serve related roles, but they are not interchangeable names for the same thing.
DáilDex: making the public record useful
DáilDex takes the same concern with clarity into Irish civic life. Parliamentary information is public, but following it can still demand more time and specialist knowledge than most people have available.
The product makes that record easier to follow. Find a representative. Understand a vote or a parliamentary question. Follow a TD and receive plain-English updates about their activity. Ask Dex a question and follow the answer back to its sources.
DáilDex has become our fastest-growing product so far. We have seen it used by multiple TDs and ministers in Ireland, as well as people working in the office of the Minister for Health and the office of the Taoiseach.
That use carries responsibility. People should be able to distinguish an official record from our explanation of it. They should be able to inspect the source. They should be able to understand the limits of an answer.
DáilDex remains politically independent and is not an official government or Oireachtas service. Its purpose is to make Irish democracy easier to understand for citizens and professionals alike.
One group of products
Leemer Group is a group of products, each with its own identity. The four names describe distinct products within one organisation.
Leemer Chat is a workspace for using AI. Leemer Labs works on models and the systems around them. Critique helps people build and examine software. DáilDex makes parliamentary information easier to follow.
Their audiences are different. Their interfaces should be different too. A developer reviewing a change needs a different experience from someone trying to understand what their TD did this week. Keeping those identities distinct helps each product make sense to the people using it.
What they share is an approach: start with a real problem, understand the constraints, build carefully and keep improving the result. The group gives that approach continuity without making every product look or behave the same way.
What we are building towards
Our aim is to build technology people can rely on. Sometimes that means research into models. Sometimes it means a better workflow, a clearer interface or a direct link to the evidence behind an answer.
We do not need AI in every part of every product. We need to choose where it helps, use deterministic software where it is the better tool and make the relationship between the two understandable.
We are building from Waterford, Ireland. Independent thinking matters to us. So does staying close enough to the work to understand when a decision needs to change.
The establishment of Leemer Group makes that direction explicit. The products have their own names. The responsibility for building them well is shared.
Different ideas. One ambition.
