How to choose without overthinking it
- Define the output. Write down the actual thing you need at the end — a finished file, a draft, a source-backed answer, a formula, a transcript or an automated workflow.
- Pick the workflow before the brand. A tool that lives inside the software you already use can beat a “better” model if it removes copying, exporting and setup.
- Test one real task. Use the same input with two candidates, compare the result and count the manual cleanup you still have to do.
What to watch out for
Generation quality and licensing vary by model. Check output rights and expect to edit the first result.

FAQ
Which AI should I try first for video generation?
Start with Runway when its workflow matches the task above. If your main constraint is different — for example native app integration, deeper control or a free tier — compare it with Adobe Firefly before committing.
Can I use these tools for free?
Many AI products offer a free tier, trial or limited free usage. Those limits change frequently, so treat “free” as an entry point rather than a guarantee of unlimited production use.
Should I trust the AI output without checking it?
No. Use AI to reduce repetitive work and speed up first drafts, then verify anything that matters: facts, formulas, source references, licensing, sensitive data and final quality.
