FAQ
What file formats are supported?⌄
PDF and modern PowerPoint formats up to 100 MB: PPTX, PPSX, POTX, PPTM, PPSM, and POTM. Export Keynote, ODP, or older PPT files to PDF/PPTX first.
How are topics detected?⌄
Deckvella reads slide titles and body text, then suggests topic groups. You can edit titles, timings, and notes, or remove a topic and rebuild it.
How is per-topic time computed?⌄
A hybrid of slide count and your priority rank. Top-ranked topics get a 1.3× multiplier, bottom-ranked 0.7×. Override any value manually.
What happens if I refresh during the talk?⌄
On reopen, Deckvella offers to resume the previous session from local storage. Snapshots are taken every few seconds.
Can I present on mobile?⌄
Planning works on mobile. Presenting is optimized for desktop or tablet — bigger screens make the timer easier to read at a glance.
