Which AI video tool should I actually use, and for what job?
The short answer
Pick by job, not hype: Veo 3.1 (inside Flow) for photoreal product shots and physics, Sora 2 for cinematic social clips with native audio, Runway for control and editing-heavy workflows, Kling for cheap volume, HeyGen or Synthesia for talking heads, ElevenLabs for voice. Most founders settle on two or three tools: one generator, one avatar/voice tool, one editor. Prices and quality rankings move every quarter, so re-test before renewing rather than marrying a stack.
A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
