Artguru Background Remover vs Knockout API

Artguru Background Remover removes the background from an image and produces a transparent PNG. It identifies the main subject and accepts JPG, PNG, and WEBP uploads. After removal, users can choose a solid color or upload a custom image as the replacement background. The product says its machine-learning tool handles detailed edges such as hair wisps and animal fur. The uploader allows up to 200 images, while batch background removal is listed as a Pro feature. The service is available on Android, iOS, and the web, with stated uses including e-commerce product photos, social media graphics, and presentation portraits. Background removal costs one credit per image, listed as $0.01 per image. Credits expire at the end of the subscription cycle and do not roll over. The privacy policy says uploaded inputs may be used to improve AI models, and that training use cannot be reversed once incorporated.

Knockout API provides image and video processing through a browser app and API. Its image tools cover background removal and replacement, batch processing, masking, smart crop, stickers, outlines, shadows, and inpainting; the API also handles upscaling, portrait restoration, colorization, and object removal. Video background removal runs asynchronously, with job polling for progress. The browser Canvas supports layered designs with text and effects, and users can save canvases and cutouts to a free account. Developers can connect through REST, any HTTP client, or official Node, React, Python, and CLI options. The service says it manages GPU processing, endpoint updates, usage records, credentials, teams, and billing. Its privacy policy says uploaded images are processed in GPU worker memory, not retained after the response, and not used to train models. The Free plan is free, with 30 images per month and 60 requests per minute. Pay-as-you-go is $0.02 a month, with metered usage billed monthly; Plus is $10 a month. Paid tiers have no monthly cap and a 600-request-per-minute limit.
