Last updated: August 2026
Hedra is built around one job: long talking-avatar video. Character-3 turns a still image plus an audio track into a lip-synced performer up to ten minutes long, at 6 credits a second. Most of the rest of Hedra Studio's video shelf is licensed models — Veo, Sora, Kling, MiniMax — each on its own per-second rate.
TL;DR — Hedra review verdict: 4.0 / 5. Buy Hedra for Character-3. On the $30 Creator plan a minute of avatar video costs about $2.00, while the same month's credits buy only 77 seconds of Sora 2 Pro. Three things the marketing does not shout: monthly credits do not roll over on any listed plan, credits are unspendable without an active subscription, and the developer API bills a separate prepaid dollar wallet that Studio credits cannot fund.
| Hedra scorecard | Out of 5 |
|---|---|
| Avatar quality | 4.5 |
| Catalogue breadth | 4.5 |
| Value per credit | 3.5 |
| Pricing clarity | 3.0 |
| Overall | 4.0 |
Every figure below is quoted from Hedra's own pricing page, docs, OpenAPI spec and legal pages, read on 5 August 2026 — no sponsored account, and no bake-off we did not run.
What Hedra Sells
Three surfaces share the brand. Hedra Studio is the consumer product: one credit balance across every model — image, video, speech, avatar — and a claimed "over 20 million users." Hedra Agent plans a job and picks models on the same credits. The v3 developer platform is a separate API with 68 models, and it is where the billing surprise lives.
Hedra Character-3 and Hedra Avatar
The model people mean by "Hedra" is Character-3. Its documented job: audio-to-video with full multi-language support, for talking and singing video with speaker selection, up to 10 minutes long. It takes a still image and an audio track, outputs 16:9, 9:16 or 1:1, and bills from one second up.
Ten minutes in a single pass
That ceiling is the differentiator. Most avatar models cap at five to fifteen seconds, so a two-minute explainer becomes a stitching job with identity drift at every seam. Character-3 does it in one pass, one face.
No first-party scene generation
The v3 catalogue also lists a model id hedra-avatar, and Hedra's model FAQ recommends "Omnia or Hedra Avatar for character videos." Character-3 remains the only avatar model with a price on the public rate card.
Character-3 is documented as an audio-to-video avatar model, not a scene generator. For camera movement and environments, Hedra Studio's card lists licensed models — Veo, Sora 2 Pro, Kling and MiniMax Hailuo — each at its own per-second rate.
Hedra Pricing and What a Minute Costs
The listed Studio tiers
| Plan | Price / credits | 60s of Character-3 | Avatar min / mo |
|---|---|---|---|
| Basic | $15 / 1,500 | $3.60 | 4 min 10 s |
| Creator | $30 / 5,400 | $2.00 | 15 min |
| Professional | $75 / 14,400 | $1.88 | 40 min |
A Teams tier matches Professional at $75, with Enterprise on custom terms. Every listed plan includes commercial use and states "Monthly Credits Do Not Roll Over." Basic costs nearly twice per credit what Creator does — skip it. Annual billing is unusual in the customer's favour: Hedra grants the whole year upfront, so a 4,000-credit plan deposits 48,000 at once.
What Every Hedra Credit Buys
Hedra's published per-second video rates, in full:
| Video model | Credits / s | Creator month |
|---|---|---|
| Hailuo 2.3 Fast Std | 4 | 22 min 30 s |
| Hedra Character-3 | 6 | 15 min |
| Kling 2.5 Turbo | 10 | 9 min |
| Kling 2.1 Master | 35 | 2 min 34 s |
| Veo 3 / Veo 3.1 | 55 | 1 min 38 s |
| Sora 2 Pro | 70 | 1 min 17 s |
The Fast variants of Veo 3 and Veo 3.1 sit at 20. Images run 4–14 credits, speech 15 per 1,000 characters. Read the video column again: a month of Creator on Sora 2 Pro yields 77 seconds; on Character-3, fifteen minutes. Those rates make Character-3 far better value than any cinematic model on the same card. Billing is per generated second — a 10-second clip costs 10 seconds.
The Credit Rules Most Hedra Reviews Get Wrong
It is easy to assume a paid plan banks what you don't spend. Hedra's does not. Every listed tier carries "Monthly Credits Do Not Roll Over," and the docs are blunter: "Credits from your monthly subscription do not carry over between billing cycles."
Rollover applies to a different product — credit packs, bought à la carte. Those never expire, and Hedra spends them only after the month's plan credits are gone. Then the clause that matters most:
You need to have an active subscription to use credits. Credits won't expire while you don't have a subscription, and if you decide to re-subscribe you'll be able to use them again.
Non-expiring, but frozen. Cancel and Hedra's FAQ says you "lose access to most functionality of the platform, apart from limited watermarked generations." A pack bought in January is still yours in June — you just cannot spend it without resubscribing.
In Hedra's favour: failed generations may be refunded automatically, logged as a matched debit and refund.
Hedra's Two Wallets
Studio credits and API credits are different money. From the v3 specification:
Fund the API wallet before your first call — this is the one bill, and it is prepaid. It is held in US dollars, it is separate from your Hedra Studio balance, and a workspace starts with $0.00 in it; nothing you buy or hold in Studio moves money into it.
Until funded, every generation returns 402 INSUFFICIENT_BALANCE.
Which Kling models have a published Hedra rate
Exactly two: Kling 2.5 Turbo at 10 credits/second and Kling 2.1 Master at 35. Hedra's models page separately advertises "16 Kling models, from V3 Pro to Motion Control to AI Avatars" inside Studio, and the v3 catalogue lists ids including kling-v3, kling-26-pro, kling-o1, kling-o3 and kling-ai-avatar-v2. What no Hedra page publishes is a per-second credit rate for any of those — so a subscriber cannot price a newer Kling job before running it.
Is Hedra Safe? The Fine Print on Faces
Hedra publishes a dedicated Biometric Data Policy, and its commitments are specific.
Biometric retention has a hard ceiling
Except to the extent required by applicable law, in no event will Hedra retain a user's biometric data beyond the date that is three years following the user's last interaction with Hedra.
Hedra also commits to express written consent where the law requires it, and discloses biometric data to vendors only as needed. Illinois, Texas and Washington residents get supplemental coverage.
Training, and a broad content licence
The Privacy Policy says Hedra may use de-identified and anonymised data "to train our AI models and for other machine learning purposes." Terms §3.2 is clean — you own your inputs and outputs. Section §3.3 is the trade-off:
You grant Hedra a non-exclusive, transferable, perpetual, irrevocable, worldwide, fully-paid, royalty-free, sublicensable right and license to use, copy, reproduce, modify... and derive revenue or other remuneration from Your Content.
Standard platform language — and also perpetual and irrevocable. If the face you upload belongs to a client, read it first. Both documents date to 25 October 2024; the Terms add binding arbitration and auto-renewal, and Hedra is not intended for under-18s.
Hedra Pros and Cons
Strengths
- Ten minutes of multi-language talking or singing video in one pass, with speaker selection.
- Avatar video at 6 credits/second — about $2.00 a minute on Creator, well under every cinematic model on the same card.
- One shared credit pool in Studio; the v3 catalogue lists 68 runnable models.
- Annual plans grant the whole year of credits upfront.
- A real Biometric Data Policy with a three-year retention ceiling.
Costs
- Monthly credits expire every cycle, on every tier, including at $75.
- No credits are spendable without an active subscription.
- Studio and API wallets are separate and non-transferable.
- Only two Kling models have a published rate, and no 4K rate is listed at all.
Where Hedra Stops and Kling 4.0 Starts
| Hedra Studio | kling4.co | |
|---|---|---|
| Talking-avatar model | Character-3 / Hedra Avatar, to 10 min | Kling Avatar V2, 10 credits/s |
| Kling models with a published rate | Kling 2.5 Turbo, Kling 2.1 Master | Kling 4.0, 3.0, 3.0 Omni, O3, Avatar V2, Motion Control |
| Developer API billing | Separate prepaid dollar wallet | Same credit balance |
| 4K output | No 4K rate published | Kling 3.0 4K and O3 4K, 65 credits/s |
| Cinematic scenes | Licensed Veo, Sora, Hailuo | Kling 3.0 Omni, 45–70 credits/s |
| Plan credits | Do not roll over | Credit packs never expire |
Hedra's specialism is the ten-minute talking head; Kling's is the shot. Kling Avatar V2 runs at 10 credits per second out of the same balance as Kling 3.0 Omni and Kling 4.0, so the presenter clip and the b-roll around it come from one wallet, one session, at the current model generation. Packs start at $9.90 for 700 credits and never expire — full rates here.
Verdict: Who Should Buy Hedra
Buy Hedra for long-form talking-head work — course modules, multilingual explainers, AI presenters, music-video lip sync. At $2.00 a minute with a ten-minute ceiling, Character-3 is priced far below every cinematic model on Hedra's own card, and Creator at $30 is the tier that makes arithmetic sense.
Look elsewhere if your work is scene-based, you need 4K, or you need a Kling model whose rate Hedra does not publish. Do not buy Basic — 80% more per credit than Creator, for a slower queue. Hedra scores four out of five: an excellent specialist model and a broad catalogue, with three billing edges its own docs disclose honestly and its marketing does not.
Want the presenter and the scene in one project? Start with Kling Avatar V2 — estimated credits show before you generate, and failed generations are never charged.
FAQ
Is Hedra AI free?
Hedra's pricing page is headed "Free Plan, No Credit Card" and invites you to "Start free, upgrade anytime," but no free tier is listed among the plans — the cheapest priced plan is Basic at $15/month. Accounts without an active subscription keep "limited watermarked generations."
Do Hedra credits roll over?
No, on any listed Hedra plan. Every tier states "Monthly Credits Do Not Roll Over" and resets each cycle. Only separately purchased credit packs carry over, and only after the monthly allocation runs out.
What happens to my Hedra credits if I cancel?
They survive but freeze — Hedra's docs say "You need to have an active subscription to use credits." They are spendable again on re-subscription; until then, watermarked output only.
How much does Hedra Character-3 cost per minute?
Six credits per second, 360 per minute — $3.60 on Basic, $2.00 on Creator, $1.88 on Professional. Billing is per generated second, so a 10-second clip costs 60 credits.
Is Hedra safe to upload my face to?
Hedra's Biometric Data Policy promises express written consent where required, and that "in no event will Hedra retain a user's biometric data beyond... three years following the user's last interaction." You keep ownership under Terms §3.2, but §3.3 grants Hedra a perpetual, irrevocable, sublicensable licence over your content.
What are the best Hedra alternatives?
For talking heads, HeyGen is the closest rival to Hedra. For presenter plus cinematic work on one non-expiring balance, Kling Avatar V2 and Kling 3.0 Omni cover both.
