Best AI Video Generators: 8 Tools Compared for Freelancers

AI video tools can turn a line of text or a photo into a short moving clip. Some can also make a “talking presenter” read your script. Others help you cut and clean up video you filmed yourself.

That is three different jobs. A tool that is great at one can be weak at another. So this guide sorts eight popular tools by what they are for, what they cost and what the free plan really gives you.

Prices checked on 1 November 2026. Prices are regular US dollar prices, before tax, as each vendor lists them. Your price may differ by country. We did not run our own tests. Everything below is based on what each vendor lists on its official pages.

First, a word about credits

Most AI video tools do not sell “videos”. They sell credits. Each clip uses up credits, and longer, sharper or fancier clips use more. For example, Runway lists that its Standard plan’s 625 monthly credits cover about 52 seconds of video with its Gen-4.5 model.

So a plan that looks cheap may only give you a minute or two of finished video a month. Before you pay, check how many seconds your credits buy, and whether unused credits roll over.

Runway

Runway makes short AI clips from text and images, and it also hosts other companies’ video models. Free plan: a one-time 125 credits that do not expire. Paid: Standard is $15 a month, or $12 a month billed yearly, with 625 credits a month. Best for: freelancers who want to try many video models in one place.

Runway lists that credits on Standard and Pro do not roll over to the next month. Only the top Max plan carries some over. During our check, Runway also showed a time-limited discount on one partner model until 30 November.

Luma (Dream Machine)

Luma makes AI video with its own Ray models and also offers some outside models. Free plan: none is listed on its pricing page. Paid: Plus is $30 a month, or $25 a month billed yearly, with 10,000 credits. Best for: people who want polished clips and need commercial use.

Luma’s pricing page lists “Commercial use” on Plus. It also lists that a 5-second clip at 1080p with its Ray model uses 400 credits, so the 10,000 credits go faster at high quality.

Pika

Pika is a playful, low-cost tool for short clips and effects. Free plan: yes, but with zero monthly credits; you can only buy credit packs, and there is no commercial license. Paid: Starter is $10 a month, or $8 a month billed yearly, with 900 credits. Best for: social media clips on a small budget.

Pika lists “no watermark” on all plans and a commercial license from Starter up. Its page also says payments are non-refundable, so start small.

Google Flow (with Google AI plans)

Flow is Google’s AI filmmaking tool. You get Flow credits through a Google AI plan, not a separate Flow plan. Paid: Google AI Plus is $4.99 a month with 200 Flow credits; Google AI Pro is $19.99 a month with 1,000 Flow credits. Best for: people who already pay for Google and want some video on the side.

Google’s plan page does not list Flow credits for free users, so we do not count it as a free option. Google lists that these plans work with personal Google accounts, and some features are for ages 18 and up.

HeyGen

HeyGen makes “talking avatar” videos: a digital presenter reads your script. Free plan: 3 videos a month, up to 1 minute each, with a watermark. Paid: Creator is $29 a month, or $24 a month billed yearly. Best for: sales videos, course intros and social posts with a presenter.

HeyGen lists that Creator removes its branding, exports in 1080p and allows videos up to 30 minutes long.

Synthesia

Synthesia is another avatar-video tool, aimed at training and explainer videos. Free plan: the Basic plan gives 10 minutes of video a month, with a Synthesia watermark. Paid: Starter is $19 a month billed monthly, or $14 a month billed yearly. Best for: how-to and training videos for clients or teams.

During our check, Synthesia also showed a lower first-month price on Starter. That is an intro offer; the regular monthly price is $19.

Descript

Descript is different: it edits video you already filmed. You edit the transcript like a document, and the video follows. Free plan: 60 media minutes a month and 720p export. Paid: Hobbyist is $24 a month, or $16 a month billed yearly. Best for: podcasts, interviews and talking-head videos.

Descript lists 1080p export without a watermark on Hobbyist. Its higher Creator plan adds AI video generation with outside models.

Adobe Firefly

Firefly is Adobe’s AI tool for images, and it can also make short video clips. Free plan: yes, with a limited number of free generations. Paid: we could not confirm the Firefly Standard US price on Adobe’s page, so we give no number. Best for: designers who already use Adobe apps.

Tools we left out

• Sora (OpenAI): OpenAI’s help center says the Sora web and app were shut down on 26 April 2026, and the Sora API on 24 September 2026.
• Other popular apps: a few well-known video apps did not show a clear US price on their official pages when we checked. We left them out rather than guess.

Commercial use, consent and disclosure

Can you use these videos for paid client work? That depends on each tool’s terms and your plan. Here is only what the pricing pages say:

• Luma lists “Commercial use” on its paid plans.
• Pika lists a commercial license from Starter up, and none on Free.
• The others do not state it clearly on the pricing page. Read their terms before client work: Runway terms, Luma terms, Pika terms, Google generative AI use policy, HeyGen terms, Synthesia legal, Descript terms.

We don’t interpret these terms for you. If a client contract depends on it, ask the vendor or a professional.

A friendly caution: some platforms and clients expect you to say when a video was made with AI. And never make an avatar or voice of a real person without their clear permission.

FAQ

Which AI video generator is cheapest?

Google AI Plus starts at $4.99 a month with 200 Flow credits. Among standalone video tools, Pika Starter ($10) and Runway Standard ($15) are the lowest monthly prices we found. Yearly billing lowers them a bit more.

Can I make videos for free?

Yes, but only a little. Runway gives a one-time 125 credits, HeyGen gives 3 short watermarked videos a month, and Synthesia’s Basic plan gives 10 minutes a month with a watermark. Pika’s free plan has no monthly credits.

What is the difference between a video generator and an avatar tool?

A video generator (Runway, Luma, Pika, Flow) creates a scene from text or an image. An avatar tool (HeyGen, Synthesia) shows a digital presenter reading your script. Pick by the video you need.

Do these tools add a watermark?

HeyGen and Synthesia list a watermark on their free plans. Pika lists no watermark on all plans. Descript lists watermark-free 1080p export on Hobbyist. For the others, check the plan page before you rely on it.

How long a video can I get for my money?

Less than you might think. Credits are spent per second. Runway lists about 52 seconds of its newest model on Standard. Check each tool’s credit table before you buy.

Which one should you pick?

• On a tight budget: start with free plans, then try Pika Starter or Google AI Plus.
• Social media creators: Pika or Runway for short, eye-catching clips.
• Client work that needs commercial use: Luma Plus or Pika Starter, which list it on the pricing page. Still read the terms.
• Trainers and course makers: Synthesia or HeyGen for presenter videos.
• Podcasters and video editors: Descript, because it edits your real footage.
• Adobe users: look at Firefly, once you confirm its price.

The bottom line

There is no single “best” AI video tool. Clips, avatars and editing are separate jobs. Start on a free plan, make one real video, and then pay for one month only. Credits go fast, so watch the seconds, not just the price.
