## 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

## Shutterstock AI Image Generator

Unlike standalone consumer text-to-image generators where copyright hygiene and commercial usage rights remain legally murky, the Shutterstock AI Image Generator is built specifically for businesses, marketers, and agencies that require clear licensing paperwork. Rather than relying solely on a single proprietary model, Shutterstock evolved its generator into a unified multi-model workspace: users can manually pick from frontier image engines—including OpenAI's GPT Image 2, Google's Imagen 4 Ultra and Gemini 3.1 Flash, and Runway Gen-4—or let Shutterstock's built-in AI Model Recommender select the optimal engine for a given prompt.

Every image downloaded from the generator ships with a Shutterstock Standard License and up to $10,000 in legal indemnification coverage, while Enterprise and Business customers can request on-demand human compliance review for full contractual indemnification and private team generations. Shutterstock also addresses ethical sourcing head-on through its Contributor Fund, which pays royalties to stock artists whose licensed works were used in training datasets, while keeping contributor-uploaded AI art out of its traditional 625-million-asset library. Note that by default on individual plans, AI images generated on the platform are added to Shutterstock's public catalog for other customers to license unless your organization is on a Business/Teams plan with private generations enabled.

In 2026—following the July 7, 2026 termination of the proposed Getty Images merger—Shutterstock sharpened its hybrid Stock + GenAI subscription lineup and launched a Claude connector (August 2026) alongside its existing ChatGPT app. Creators who only need AI visuals can subscribe to the standalone GenAI plan at $15/month billed annually ($180/year) or $29/month month-to-month for 100 monthly generation credits. For teams blending authentic photography with synthetic graphics, Unlimited Images ($29/month billed yearly) bundles unlimited downloads from 83M+ curated stock photos with 50 AI credits/month, while Unlimited Plus ($69/month billed yearly) unlocks 100M+ stock images, videos, music, and SFX alongside 100 monthly AI credits.

**Pricing & Plans:** New users get 2 free trial generations, after which the standalone GenAI subscription costs $15/month billed annually ($180/year) or $29/month with no contract for 100 AI generation credits per month. AI generation credits are also bundled into stock subscriptions, including Unlimited Images ($29/mo billed yearly with 50 AI credits/mo) and Unlimited Plus ($69/mo billed yearly with 100 AI credits/mo), alongside custom Teams and Business indemnification plans.

- **Multi-Model Selector & AI Model Recommender:** Provides single-dashboard access to leading third-party visual models—including OpenAI GPT Image 2, Google Imagen 4 Ultra, Gemini 3.1 Flash, and Runway Gen-4—with an automated recommender that matches prompts to the best engine.
- **Standard Commercial License & $10,000 Indemnification:** Attaches a commercial Shutterstock Standard License and $10,000 legal indemnification to every downloaded AI image, with full human-reviewed indemnification available on Enterprise and Business tiers.
- **AI Image Editor & Generative Outpainting:** Includes browser-based inpainting, magic object erasure, background removal, image reference guidance, and aspect-ratio canvas expansion that routes royalties directly to the original contributor when editing stock photos.
- **Unified 625M+ Stock & GenAI Search with Claude/ChatGPT Apps:** Displays stock photos, vectors, 3D assets, and AI generation options in one workflow, complemented by official ChatGPT and Claude connectors for conversational asset discovery.
- **Ethical Contributor Fund Compensation:** Compensates hundreds of thousands of human photographers and illustrators via Shutterstock's AI Contributor Fund while enforcing strict DE&I and brand-safety guardrails.

**Strengths:** Every downloaded AI image includes a clear commercial Standard License backed by $10,000 legal indemnification; Aggregates top frontier models (GPT Image 2, Imagen 4 Ultra, Gemini 3.1 Flash, Runway Gen-4) under one $15/mo annual plan; Seamlessly combines 625M+ authentic stock assets with generative AI tools and ChatGPT/Claude assistant connectors; Ethically compensates human artists through the Contributor Fund and pays direct royalties on AI-edited stock photos

**Limitations:** Images generated on individual plans are added to Shutterstock's public library and are not exclusive unless on a Business/Teams plan; Unused monthly generation credits (50 or 100/month) expire at the end of each monthly billing cycle; Experimental AI Video Generator outputs do not yet carry commercial licensing coverage, limiting them to previsualization
