ReMark

Yes. The Autodesk App Store lists ReMark by LezSoft as Free for 64-bit Windows. The same project is published on Codeberg under the GNU GPL, and the README says it works with Revit versions after 2020. There is no paid tier on the store listing. Support email is info@lezsoft.com.

No. The Autodesk App Store listing is for Win64. ReMark is a Revit add-in, so it runs inside Autodesk Revit on Windows, not as a Mac, Linux, or browser app. The App Store build reviewed on 30 Sep 2026 is version 1.1.1, last updated 13 May 2026.

It edits the Mark parameter inside a Revit project. It does not import or export IFC, DWG, or other file formats. The written value follows prefix, optional level, progressive number, and suffix, with examples such as Wall.1.1 or 1.1.Wall. If a coordinator needs those marks in IFC, that still happens through Revit's own IFC export after the marks are set.

CADnotes (March 2023) compared both free tools on the same Mark job. ReMark can add level numbers in one pass, but it does not let you choose the sequence direction. DiRootsOne's ReOrdering tool can write a parameter other than Mark, limit the run to the active view or current selection, and order elements by a manual pick or a detail line. Use ReMark when the level segment matters more than sequence control.

The Codeberg README says ReMark is compatible with all Revit versions after 2020. A commit on 18 April 2026 ports the project to .NET 10 to support Revit 2027. The App Store package is version 1.1.1 for Win64. Install the build that matches the Revit year on the machine.

It is for people already documenting in Autodesk Revit who need consistent Mark values, such as door numbers. CADnotes describes Mark as a field teams use when Revit's own increment is not enough for prefixes, suffixes, or level numbers. The add-in is category-wide: you check the categories, then Apply. It is a poor fit if you need to number a custom parameter or control the order element by element.
