Frequently Asked Questions about Granthos

Does GranthOS include real-time collaboration, and is it available on the free plan?

Real-time collaboration is a Pro and Lifetime feature, not included in the free tier. On Pro (₹499/month) or Lifetime (₹2,499 one-time), you can work with co-authors simultaneously on the same document. The free plan gives you 25 AI edits per week and 5 PDF downloads per week, enough to test the core browser-based editing and compilation.

Can GranthOS convert my existing Word documents or PDFs into LaTeX?

GranthOS explicitly supports Word-to-LaTeX conversion as a documented use case. For PDF conversion or other format imports, check their site to confirm the full range of supported input formats, as the details are not specified.

What's the difference between the Pro plan's 500 monthly AI edits and the Lifetime plan's unlimited edits?

The Pro plan (₹499/month at current 50% discount) caps you at 500 AI edits monthly. The Lifetime plan (₹2,499 one-time payment, also 50% off) offers unlimited AI edits per month alongside lifetime updates and API access. If you generate equations, TikZ diagrams, and use the question paper generator regularly, Lifetime pays for itself faster.

How fast does GranthOS compile LaTeX to PDF in the browser?

GranthOS compiles LaTeX in under 100 milliseconds without requiring local TeX installation. The browser-based compilation means you see your PDF preview instantly as you edit, and it works on any device with no setup.
