Text-to-video AI tools turn a written prompt into a short video clip. The indie tools listed here either run their own models (LTX 2.3) or wrap several third-party models — Seedance, Veo, Kling, Wan — in one workspace so you can compare outputs without separate subscriptions.
Most produce short clips (a few seconds to around ten), with credits-based pricing and free credits for testing. Several also accept an image as the starting frame, which is usually the better path when you need a specific subject.
How to choose
Decide whether you need one strong model or several. Single-model tools are cheaper and more predictable; multi-model workspaces cost more per clip but let you pick the model that handles your scene best. Check maximum clip length and whether audio is generated or silent.

Frequently asked questions
Which text-to-video tool is free?
Upsampler offers a free tier for video generation, and most others provide free trial credits. Fully unlimited free text-to-video does not exist because each clip costs the maker GPU time.
Can these tools generate audio with the video?
Some can. LTX 2.3, for example, generates synchronized audio; many others output silent clips that you add sound to separately. Each tool page states what the maker supports.
What is the difference between text-to-video and image-to-video?
Text-to-video invents the whole scene from a prompt. Image-to-video animates a picture you supply, which gives far more control over the subject and framing. Most tools here support both.
