About Vahtian

Research software built by a researcher

Vahtian develops software for researchers who want AI to accelerate their work without making their evidence less transparent.

The products are designed around a simple principle. Every scientific claim should remain traceable to the evidence that supports it, and the researcher should always remain responsible for that judgment.

AI can help identify, summarize, and compare evidence. It should not quietly decide whether a citation supports a conclusion.

That principle shapes every Vahtian product.

Why Vahtian exists

Writing scientific papers has changed rapidly. Finding literature is faster. Drafting text is faster. Reviewing evidence is increasingly assisted by AI.

One part of the workflow has not become easier: verifying that every citation genuinely supports the claim it accompanies. That verification is often manual, difficult to revisit, and rarely documented in a consistent way.

Vahtian was created to make that process easier to perform, easier to review, and easier to repeat.

The goal is not to replace scientific judgment. The goal is to document it.

How the software is designed

Vahtian follows a few principles that guide every product.

  • Researchers make the final decisions.
  • AI provides assistance, not authority.
  • Assessments should be transparent and reproducible.
  • Whenever possible, researchers should be able to work locally and retain control of their own data.
  • The software should produce records that can be inspected, shared, and reproduced.

These principles matter more than any individual feature. Interfaces will evolve, but the design philosophy remains the same.

Who builds Vahtian

Vahtian is developed by Heidi Andersén, MD, PhD, a clinician-scientist working in respiratory medicine, oncology, and clinical research in Finland.

The software grows directly from day-to-day research experience: designing studies, writing manuscripts, reviewing evidence, collaborating across multidisciplinary teams, and using AI in scientific workflows.

Rather than building software for researchers from the outside, Vahtian is built as part of an active research practice.

Built for long-term trust

Most Vahtian software is designed to work locally on the researcher’s own computer whenever practical. The open-source components are released under the Apache 2.0 licence. Commercial services focus on collaboration and infrastructure rather than restricting access to core research workflows.

Scientific conclusions belong to researchers. Vahtian provides tools for documenting how those conclusions were reached.

The name

“Vahti” is the Finnish word for a guard or sentinel. The name reflects the purpose of the software: helping researchers keep watch over the evidence behind their work.
