Runway vs Pika vs Luma AI: I Made Video From a Single Prompt in All Three

I typed the same prompt into Runway, Pika, and Luma AI and watched what came back, because 'text to video' still means three very different things depending on which app you open. If you're picking one, the deciding factor is what you'll actually do with the clip.

Runway runs the most controllable video models and packs a pile of editing tools in one place, which is why it's the default for people who care about the shot. The catch is that credits burn fast if you're experimenting and motion still glitches on hands - expect to reshoot the same prompt a few times.

Pika turns a prompt or image into a quick social clip and ships fun effects aimed at short-form video. It's the fastest of the three to something shareable, but clips stay short and physics still slips on anything with real movement, so it's a hook generator, not a scene builder.

Luma AI makes the smoothest, most real-looking short clips of the bunch and handles motion better than expected for the price. The limits are that clips run shorter than Runway's and prompt adherence slips on complex scenes - it's great for a vibe, weaker for a specific shot.

My pick: Runway when you need control and will edit, Pika for a quick social hook, Luma for a smooth realistic clip on a budget. All three still want a human to decide the shot is good enough to ship.
