Verdict: 60 free clips/mo (watermarked). Best free tool for turning one long video into Shorts. -
CapCut — generous free video editing for Reels/TikTok/Shorts.

Best free AI scheduler
- Buffer — free for 3 channels with the AI Assistant included.
-
Publer — free basic scheduling; AI + analytics sit on paid Business.
Verdict: Free tier covers basic scheduling. AI features and analytics need a paid Business plan.
When is it worth upgrading?
Free is enough until you hit one of these — then a paid plan pays for itself:
- You keep hitting word/post/credit limits mid-week.
- You need more than ~3 channels.
- You want real analytics to see what’s working.
- Watermarks on your video clips look unprofessional.
