The wider network
Beyond the tools
Separate sites built on the same idea: useful, quick, and free to open.
One page instead of 23 browser tabs
smartJOANS Smart Tools collects the small jobs that usually send you hunting for a sketchy download or a paywalled site. Students, freelancers and small businesses use the same 23 tools here — the difference is nobody is asked to sign up, and nothing is watermarked.
The PDF suite covers the everyday six: merge, compress, crop, delete pages, PDF to image and PDF to EPUB. The AI humanizer rewrites stiff machine text into something a person would actually say. The QR generator produces clean codes with no logo stamped in the corner.
For makers, the online 3D viewer at artintentions.in opens 11 formats — STL, GLB, GLTF, FBX, OBJ, 3DS, DXF, PLY, DAE, 3MF and ZIP — straight in the browser, and 3D printing turns those files into physical parts.
On the money side there is a loan EMI calculator with a full amortisation view and a scientific calculator for everything else. Most tools do their work inside your browser, which is why they are fast and why your files stay on your machine.
