CalcAuthor

CalcAuthor vs Blockpad

Blockpad and CalcAuthor both combine calculations with document authoring. CalcAuthor runs entirely in the browser and is built around team roles, shared folders, and document locking from day one.

Common questions when switching

Blockpad already combines calculations and documents — what's different?

Blockpad's "calculation word processor" idea is close to CalcAuthor's own positioning, and it's a real desktop alternative worth considering. The differences are in the details: CalcAuthor runs entirely in the browser with no install, and adds team-specific features (roles, shared folders, document locking, seat management) built for firms, not just individual engineers.

Does Blockpad have a free trial?

Blockpad offers free tiers for education and file viewing, plus paid licenses starting around $18/month. CalcAuthor's 7-day free trial applies to the full paid product, on either plan, with no credit card required to start.
