The Verdict: Hedra

Hedra is the pick when the face itself is the content. Character-3 gives portraits and illustrated characters a level of expression that corporate presenter tools do not chase, and the 10 minute ceiling suits songs, stories and long takes, not just short clips.

Go in with eyes open on the billing. There is no free Studio plan to learn on, plan credits vanish at the end of each month, and costs shift with the model you pick, so heavy users need to watch the meter. Teams that need training structure, stock presenters or SCORM should look elsewhere. Character-driven creators will not mind.

What is Hedra?

Hedra is an AI character video platform that turns a single portrait and an audio track into a talking or singing character video. Its own Character-3 model reads the audio and drives the face, adding lip sync, blinks, eye shifts and small head movements that follow the delivery. The clip runs as long as your audio, up to 10 minutes, and renders at up to 1080p in aspect ratios from square to vertical to widescreen.

That makes Hedra a different animal from presenter tools. There is no library of stock spokespeople and no course builder. You bring the character, whether that is a photo of a person, an illustrated mascot or a stylized figure, and Hedra makes it perform. Speaker selection supports more than one voice in a scene, and a text prompt can steer how the character delivers the lines.

The same account also reaches a wider model catalog. Studio runs on monthly credits charged per generated second, and the developer API opens 110+ video, image, audio and text models behind one key and a prepaid wallet, with SDKs for Python and TypeScript. Creators tend to live in Studio, while developers plug the avatar and lip sync models into their own products.

Entry plan generations run slower than the higher tiers

FAQs

Is Hedra free to use?

▼

Hedra does not list a free plan or trial for Studio on its pricing page. Regular use needs a paid monthly plan, and the API wallet starts empty and must be funded before generations run. Cancelled accounts keep only limited watermarked generations.

How much does Hedra cost?

▼

Studio runs on monthly credit subscriptions, starting with an entry plan and rising through tiers that add more credits and faster generation, with a custom Enterprise option on top. The API is separate and pay per use, billed per second of output from a prepaid balance with no subscription or seat fees.

What is Hedra Character-3?

▼

Character-3 is Hedra's own audio driven character model. Give it a start image and an audio track and it returns a talking or singing video up to 10 minutes long, at up to 1080p, with natural micro expressions and multi-language support.

How do Hedra credits work?

▼

Credits are charged by the length of video you generate, so a 10 second clip costs 10 seconds of credit rather than a full minute. Monthly plan credits reset at the start of each billing cycle and do not roll over. Credits bought in packs never expire and are spent only after your plan credits run out.

Can I use Hedra videos commercially?

▼

Yes, on a paid plan. Hedra states that commercial rights and unwatermarked output come with every paid Studio plan, so publishable work belongs on a subscription rather than on any limited free generation.

Does Hedra have an API?

▼

Yes. The developer API covers 110+ generation models across video, image, audio and text behind one API key and a prepaid dollar wallet, with Python and TypeScript SDKs, a CLI and an MCP server. API usage bills the wallet directly, separate from Studio subscription credits.

What do I need to make a talking character in Hedra?

▼

A clear portrait to use as the start frame and an audio track, since the audio sets both the words and the length of the clip. An optional text prompt can steer how the character delivers the lines. Clean audio and a well lit, front facing portrait give the model the best material to work with.
