Best AI video generators

By Cathy Riddell · Prices checked 31 Oct 2026 · Last updated 31 Oct 2026

Short answer: For business videos such as training, onboarding and explainers with an AI presenter, I’d start with Synthesia: it has a free Basic plan, paid plans from US$14/mo billed yearly (US$19 monthly) as of Oct 2026, AI avatars and 140+ languages and voices. HeyGen is the closest alternative with a free plan of its own; Descript suits editing your own recordings; Pictory turns scripts and articles into stock-footage videos.

How this page was made: I compared each vendor’s official pricing and feature pages on 31 Oct 2026. Hands-on test notes are added only after I’ve used the product on a real account; until then they’re marked as pending. My review method.

What should I look for in an AI video generator?

  • What you’re making: a presenter-led video (avatar tools), edits of your own footage (editors) or videos built from text and stock footage.
  • Watermarks and export: free plans usually add a watermark.
  • Languages: if you sell or train across countries.
  • Credits: most tools now meter usage in credits, so check what a typical video uses.

Synthesia: best for business training and explainer videos

Synthesia turns a script into a video presented by an AI avatar. As of Oct 2026 its official pricing page lists:

PlanPriceWhat the official page lists
BasicFree10 minutes of video a month, 9 AI avatars, videos carry a Synthesia watermark
StarterUS$19/mo, or US$14/mo billed yearly (US$168/yr)Download videos, no watermark, 125+ AI avatars, 3 personal avatars, AI Video Assistant, 3 guests

EnterpriseCustomUnlimited video minutes, 1-click translation into 140+ languages, SSO, SCORM export

Every plan lists 140+ languages and voices, and the page says Synthesia is SOC 2 and GDPR compliant. Paid plans use credits; Synthesia says a typical finished minute uses about 100 credits and unused allowance doesn’t roll over.

Trade-offs: videos on the listed plans run up to 3 minutes each, and there’s no pay-per-video option.

Pictory: best for turning scripts and articles into videos

Pictory builds videos from text, using an AI video agent, AI voices from ElevenLabs and stock footage from Getty Images and Storyblocks. It lists Starter, Professional, Teams and Enterprise plans, with a free trial. Its pricing page was showing discounted prices when I checked, so I haven’t quoted one; see the official pricing page.

InVideo: AI generation plus a timeline editor

InVideo combines AI image and video generation models with a full timeline editor, sold as Starter, Plus and Max plans with monthly credits. It was running a time-limited sale when I checked, so I haven’t quoted a price; see the official pricing page.

How do I choose?

  1. Decide whether you need an on-screen presenter (Synthesia, HeyGen) or want to edit your own footage (Descript).
  2. Make one real video on a free plan or trial before paying.
  3. Check the credit cost of the length and style of video you’ll make most.
