## HeyGen

HeyGen removes the biggest bottlenecks in corporate video production: cameras, talent, studios and reshoots. You start from a script, slide deck or PDF, choose one of hundreds of ready-made stock presenters or train a custom avatar from your own footage, and the platform generates a talking-head video with synchronized lip movement. Because the avatar is a model rather than a filming session, updating a sentence in a compliance training module or a product launch script means regenerating text, not booking a studio day.

Localization is where HeyGen is strongest. Videos can be translated and dubbed into more than 175 languages and dialects, with editable translation scripts, brand glossaries, the option to switch or upload voices, and proofreading seats so a native speaker can validate the output. The Video Agent and Avatar engines handle longer-form content, 4K export on higher tiers, cinematic avatar scenes and motion or gesture control. Beyond plain generation, HeyGen supports interactive video with quizzes, branching, video-link embedding and SCORM export for learning management systems, which is why it is widely used in L&D and enablement.

Team and enterprise features include shared workspaces, a brand kit and asset library, comment and draft collaboration, SAML/SSO, SCIM provisioning and MFA, plus integrations with Zapier, Make, n8n and HubSpot. There is also an API and a ChatGPT plugin. Pricing follows a freemium structure: a free tier with watermarked videos, then Creator, Pro, Business and custom Enterprise plans billed monthly or annually.

**Pricing & Plans:** Freemium with tiered subscriptions. The Free plan is $0 and allows up to 3 watermarked videos a month of up to 1 minute each. Creator is $29/month, Pro (most popular) is $49/month, and Business is $149/month for teams, with additional seats around $20/seat/month. Annual billing offers roughly two months free. Enterprise pricing is quoted via sales, and API usage is billed separately.

- **AI avatars from text:** Choose from 500+ stock presenters, use photo avatars, or train a custom Video Avatar that looks and sounds like you, then generate narrated videos straight from a script.
- **Video translation and dubbing:** Localize one recording into 175+ languages and dialects with editable scripts, brand glossaries, voice switching and proofreading seats for native-language review.
- **Video Agent and frontier models:** An agentic workflow expands ideas into finished videos, with access to leading generative models for video and image generation on higher plans.
- **Interactive and LMS-ready video:** Add quizzes, branching and decision points, embed videos by link, and export SCORM packages so content drops straight into corporate learning systems.
- **Team workspaces and security:** Shared workspaces, brand kits, asset libraries, draft collaboration, SAML/SSO, SCIM provisioning and MFA cover the governance needs of larger organisations.

**Strengths:** Removes the need for cameras, studios and on-camera talent, dramatically cutting video production time; Broad localization support covering 175+ languages and dialects with editable scripts; Strong enterprise readiness including SSO, SCIM, brand controls and LMS integrations; Free tier and annual discounts let teams test the workflow before committing

**Limitations:** Credits are the real constraint: heavy usage on higher-resolution exports burns through them quickly; Avatar realism can still fall into the uncanny valley for some viewers and use cases; Serious production volume requires a paid plan, and enterprise pricing is quote-only

## PoseTracker API

PoseTracker solves a specific problem: most digital fitness products are blind coaches. They play a video, hand out a plan, and never look at the person actually moving. PoseTracker gives the product eyes by running pose estimation on the phone itself, so a camera feed becomes 17 COCO keypoints in real time without uploading video anywhere.

The stack is built for shipping fast. A React Native package (works in Expo Go) and a browser JavaScript build both use the same on-device MoveNet engine, so keypoints are free and require no API key. When an app needs semantics on top of raw coordinates — is that a valid squat rep, what is the knee angle, does this push-up meet form criteria — an optional API key unlocks a hosted engine that returns reps, angles and a form score. A classic WebView or iframe integration remains available for teams that already embed a web view.

Beyond reps, the platform offers built-in tools including a back flexibility test, a flexibility analysis tool with automatic angle detection, and a pose comparison system that scores a user against a reference position. Browser benchmarks published by the team put MoveNet Lightning around 51 FPS on an iPhone 12 and 34 FPS on a Pixel 5. On-device inference means the video stream never leaves the device, which simplifies privacy and cuts bandwidth for fitness and rehab use cases.

**Pricing & Plans:** Freemium with a paid developer tier. The free plan covers keypoints at no API key plus up to 200 tracking API calls per month and 100 AI assistant credits, restricted to non-commercial use. The Developer plan is €50 per month with 1,000 tracking API calls included and commercial use, and a tailor-made Business plan is available on request.

- **On-device MoveNet keypoints:** 17 COCO keypoints stream directly on the phone or in the browser with no API key and no video upload.
- **Rep, angle and form engine:** An optional API key returns repetition counts, joint angles and a movement form score for exercises like squats and push-ups.
- **React Native and web SDKs:** One engine with three integration paths: native React Native (Expo Go), browser JavaScript, and a WebView or iframe embed.
- **Built-in motion tools:** Ready-made back flexibility test, flexibility analysis with automatic angle detection, and pose comparison against a reference position.
- **Custom movement support:** Describe a movement, context and stack and the in-page assistant returns a React Native, Expo or web snippet on the same engine.

**Strengths:** Keypoints run on-device, so video never leaves the phone; Free tier with 200 API calls per month makes prototyping inexpensive; One engine covers React Native, iOS, Android, web and low-code embeds; Additional form scores, angles and flexibility tools go beyond raw keypoints

**Limitations:** The free tier is limited to non-commercial use and a strict monthly call cap; Semantic outputs such as reps and form scores require an API key and credit balance; On-device accuracy depends on phone hardware, lighting and camera framing
