Requirements that fit the project
Technology, capacity, location and constraints shape the required permits. MitOS derives the route from project facts and links requirements to the relevant articles of law.
Energy permitting software
Keep permit requirements, supporting documents and legal references together. MitOS helps development teams understand the path ahead and the evidence behind each step.

Documents beside the permit
Open a stage to see its documents, responsible authority and deadlines. Keep the evidence beside the decision it supports, so a project review starts from the same record.
A route that responds to change
When project facts change, MitOS re-derives the permitting path. Teams can review the resulting requirements in context instead of maintaining a separate checklist for each change.
How it works
From project facts to the permits they require.
Technology, capacity and location set the route. Open any stage for its documents, the responsible authority and the clock attached to it, with the legal article behind each requirement.
- 01
Describe the project
Enter the technology, the capacity and the location. MitOS derives the permitting path from the law itself, and every requirement carries its legal citation.
- 02
See who decides, and by when
Every step names the office that decides it and the statutory clock that governs it, or says plainly that the law sets no time limit.
- 03
When a fact or the law changes
Change one project fact and the whole path re-derives. When the law changes, an in-flight project keeps its pinned legal basis, sees a reviewable diff and adopts the change explicitly, with the amending act cited.
Questions before your demo
Does MitOS submit permits to authorities?
MitOS organizes requirements, documents and progress. Your team remains responsible for checking applicability and submitting applications through the relevant authority channels.
Can we use a desktop or cloud edition?
MitOS is available as a desktop application with a local or network database, or as a cloud workspace for teams. Discuss your deployment needs during the demo.
Which countries' law is built in?
Greek, Italian and Swiss law, cited to the article. Your team confirms how it applies to each specific project.
