CollabGEO review
A free shared geometry canvas for constructing, measuring, and discussing 2D figures.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
CollabGEO is a browser-based 2D geometry canvas from the National Informatics Centre’s Education Projects Division, intended for teachers, tutors, students, and other public users. It suits small groups that need to create and explore figures together: users can make points, lines, arcs, circles, polygons, and conic sections, then adjust them with mouse or touch controls or an input bar. Measurement tools cover lengths, areas, perimeters, radii, and circumferences. The web application is free and supports Hindi and English interfaces and guides.
Its defining strength is collaborative construction rather than individual practice. A shared session URL lets participants work together in real time, while text annotations and freehand sketches support explanation on the canvas. Work can be saved and reopened; users can import SVG files, export the canvas as SVG or PNG, and print it. DIKSHA is listed as an integration, giving the tool a connection to an education platform. These capabilities make CollabGEO a practical fit for a class demonstration, tutoring session, or small-group exploration where learners benefit from seeing constructions change together.
The trade-off is its narrow learning scope. The category specifications indicate dynamic constructions and classroom tools, but not proof practice or problem practice, so learners seeking structured exercises or proof development should look elsewhere. Offline use is limited to basic canvas work after the page loads; saving and collaboration need an internet connection. The application is hosted on NIC cloud, and email is the listed support channel. Choose CollabGEO for accessible shared 2D geometry work, especially when a free browser tool and export options matter. It is less suitable as a standalone geometry course or a practice system centered on assessment and proofs.
