Comparison
Trade-off scorecard
| Pick | Price friction | Capability gap | Setup friction |
|---|---|---|---|
| Synthesia | Free tier capped at 10 min/mo with a watermark; Starter plan's $18/mo rate requires annual billing, $29/mo month-to-month | Built narrowly around a presenter reading a script — not a general video editor, so it won't cut or arrange footage you already have | Minimal once a script exists — no filming or recording needed, but avatar/voice selection takes some trial and error to match tone |
| InVideo | Free tier limits AI-generated minutes per week and adds a watermark; paid plans start roughly $20-25/mo depending on billing cycle | Broader toolset than Synthesia or Pictory, which per public reviews can mean more setup decisions for a simple explainer | More template and timeline options to learn versus a narrower single-purpose tool |
| Pictory | No ongoing free plan per its pricing page — only a time-limited trial, then $25-29/mo | Purpose-built for converting existing text/scripts into video; not designed for filming-style editing or an on-screen avatar | Workflow is described as straightforward on the vendor's site: paste or upload a script, get matched stock footage and captions |
Explainer videos usually need one of two things: a presenter talking the viewer through something, or a clean, captioned montage that narrates over visuals. “Best AI tool for explainer video creation” isn’t one answer, because those are different production jobs. This guide compares three tools that are commonly recommended for the category — Synthesia, InVideo, and Pictory — based on each vendor’s public pricing pages, feature documentation, and widely available reviews.
How we compared
This comparison is built from public information: each tool’s official pricing page, published feature lists, and independent reviews that are visible without an account. We have not run hands-on production tests on these three tools for this article, so treat the notes below as a starting point for evaluation, not a verdict on output quality. Where a price or limit is stated, it reflects what the vendor’s own pricing page listed at time of writing — check the current page before buying, since AI tool pricing changes often.
Synthesia — best for an on-screen AI presenter
Synthesia’s core feature is an AI avatar that delivers your script on camera, in dozens of languages, without filming anyone. Its pricing page lists a free plan (10 minutes of video per month, 9 stock avatars, watermarked output) and a Starter plan starting at $18/month if billed annually ($29/month month-to-month), which removes the watermark and unlocks 125+ avatars and video downloads. A Creator plan at $64/month annual ($89/month monthly) adds more avatars and API access.
For explainer videos where the viewer benefits from something that reads like a person speaking directly to them — onboarding, training, software walkthroughs with a narrator — this is the category Synthesia is built for. It is not positioned as a general video editor; its documentation doesn’t describe footage-cutting or timeline editing features the way InVideo’s does.
InVideo — best all-round editor
InVideo’s public pricing page lists a free plan with a capped number of AI-generated minutes per week and a watermark on exports, plus paid plans reported by multiple pricing trackers to start around $20-25/month depending on annual vs. monthly billing, scaling to roughly $48-60/month for higher tiers with more credits. InVideo’s feature list covers AI generation from a prompt or script, editing of footage you already have, and a large stock/template library — a broader toolset than either Synthesia or Pictory.
For an explainer video that’s closer to a captioned, visually varied montage than a talking-head presentation, or if you’re not sure yet exactly which format fits your project, InVideo’s flexibility is the safer starting point according to its own feature documentation.
Pictory — best for converting an existing script into video fast
Pictory’s site describes a narrower, specific workflow: paste in a script, article, or transcript, and it generates a captioned video with automatically matched stock footage. Its pricing page lists a Starter plan at $25/month billed annually or $29/month month-to-month, with no ongoing free plan — only a time-limited trial.
If the explainer already exists as written content — a script, a blog post being repurposed, a webinar transcript — Pictory’s documented workflow is the most direct path from text to a finished video, according to its own product pages.
So which one fits your explainer video?
Match the tool to the format, based on what each vendor’s own pages say it’s built for: an on-screen AI presenter points to Synthesia, general editing flexibility or footage you already shot points to InVideo, and starting from an existing script or article points to Pictory. All three publish free access of some kind (Synthesia and InVideo have ongoing free tiers; Pictory offers a trial), so the cheapest way to evaluate fit is to test the free or trial option against your actual script before committing to a paid plan.

Teams needing a fully custom, hand-edited explainer with unique motion graphics. All three tools work from templates and generated assets — public reviews consistently describe them as fast, not as replacements for a motion-design agency or a dedicated editor like After Effects.
One-off, single-video projects with no plan to make more. A free tier or trial should cover a single short explainer; the paid plans are built for ongoing production, not a one-time need.
Frequently asked questions
What is the best AI tool for making an explainer video?
It depends on the format. If the explainer needs a presenter talking on screen, Synthesia's avatar feature is built specifically for that. If the explainer is closer to a captioned montage narrating over visuals, InVideo or Pictory are the more natural fit — InVideo for more editing control, Pictory for converting an existing script or article fastest.
Can I make an explainer video with AI for free?
Yes, to a point. Synthesia and InVideo both list ongoing free tiers on their pricing pages (limited minutes, watermarked output). Pictory's public pricing page shows a time-limited trial rather than a permanent free plan, so budget for a paid plan if Pictory's specific workflow is what you need.
Do I need an on-screen presenter for an explainer video, or is captioned footage enough?
Neither is objectively better — it depends on the content. Product and software explainers often work fine as captioned footage with voiceover (InVideo or Pictory). Training material, onboarding, and anything that benefits from a sense of a person speaking directly to the viewer tends to favor an avatar-based tool like Synthesia.
How much does an AI-made explainer video typically cost per month?
Based on current vendor pricing pages, expect somewhere in the $18-30/month range for a usable paid plan on any of these three tools, with Synthesia's cheapest paid tier landing lowest at $18/month when billed annually. All three also publish higher tiers ($60-90+/month) for more video minutes, avatars, or team seats.
