Is HelloGen really free?
Making images is: unlimited on a free account, never watermarked, commercial license included. Video runs on credits — from a Basic or Pro plan, or a one-off pack from $4.90 — because every clip is paid compute. The plan card shows the exact price before you generate, and failed generations are never charged.
Do I need to know how to write prompts?
No. Describe what you need in plain words; the assistant picks a skill, asks at most one question and writes the prompt for the model. You can always open and edit the prompt yourself.
How much does the assistant cost?
It is metered by tokens and converted to credits: a typical turn costs about 0.4–0.7 credits — a few percent of one image. Free accounts get 10 turns a day; Basic and Pro pay from their monthly credits and see the cost on every message.
Which AI models does it use?
Nano Banana (Lite / 2 / Pro), Seedream 4.5 / 5 and GPT Image 2 for images; Veo 3.1, Kling 3.0, Seedance 2–2.5, MiniMax H3 and HappyHorse for video. The assistant chooses per job — you can always ask for a cheaper or a better one.
Can I use the results commercially?
Yes. Everything you generate comes with a commercial license and no watermark, on every plan.
What if a generation fails?
You are never charged for failed generations, and the plan card shows the exact price before you press Generate.
Can I make my own skill?
Yes — save a custom skill (your own recipe for a recurring job) and the assistant uses it like the built-in ones. Limits depend on your plan.
