# Tools

Polished, generally useful software. Everything here runs in the browser unless noted.

## Documents

- **[mdshare](https://vault1.magland.org/tools/mdshare)**
  ([live](https://mdshare--tools.vault1-sites.magland.org/)).
  A split-pane markdown editor (LaTeX math, highlighted code, mermaid
  diagrams) where the document is compressed into the URL itself, so sharing
  is just copying the link; no server, nothing uploaded.

## Meetings

- **[commonroom](https://vault1.magland.org/tools/commonroom)**
  ([live](https://commonroom--tools.vault1-sites.magland.org/)).
  Serverless group video calls: pick a room name, share the link, and everyone
  in the room is connected over a full WebRTC mesh (up to 8 people), with
  room-wide shared settings. See also
  [commonroom-recorder](https://vault1.magland.org/proof-of-concept/commonroom-recorder),
  which joins a call and records it for transcription.

## Geometry and meshing

- **[mesh-studio](https://vault1.magland.org/tools/mesh-studio)**
  ([live](https://mesh-studio--tools.vault1-sites.magland.org/)).
  Build CAD primitives or import STEP/IGES with
  [OpenCASCADE.js](https://ocjs.org/), then inspect them in 3D, including each
  face's true NURBS surface (polynomials on faces), not just its triangulation.
- **[mesh-converter](https://vault1.magland.org/tools/mesh-converter)**
  ([live](https://mesh-converter--tools.vault1-sites.magland.org/)).
  Convert meshes between 19 formats (PLY, OBJ, STL, VTK, Gmsh, XDMF, …) with
  [meshio](https://github.com/nschloe/meshio) running in-browser on Pyodide;
  inspect meshes in 3D and see what a lossy export would drop.

## Numerical computing

- **[numbl-figure-viewer](https://vault1.magland.org/tools/numbl-figure-viewer)**
  ([live](https://numbl-figure-viewer--tools.vault1-sites.magland.org/)).
  Open a figure exported from [numbl](https://numbl.org) and render it, with
  the underlying data included.
