DescriptionBigjpg enlarges existing artwork, illustrations and photographs with AI reconstruction. It can smooth noise and redraw edges, but cannot guarantee that reconstructed details match the original scene. Check faces, linework, lettering and product details at the final viewing size. It is an image upscaler, not a text-to-image generator. Free allows 20 pictures per month, up to 4x enlargement and a 5MB upload. Basic costs $6 for two months with 500 pictures per month; Standard costs $12 for six months with 1,000 per month; Premium costs $22 for twelve months with 2,000 per month. All three paid packages allow up to 16x enlargement and 50MB files, with priority processing, parallel jobs and batch mode. Package duration and monthly image allowance are separate. Offline processing is available with an account, including Free. If you submit without logging in, keep the browser open while processing. The official API is available to paid members after login; check its account-specific limits before building an automated workflow. Compare VanceAI for an online credit-based workflow or a separate Windows application. The June 23, 2026 terms name Guangzhou Datu Technology Co., Ltd. as the operator and leave ownership of uploaded images with the user. You must have the rights needed to process them. The privacy policy says uploads are not used to train models and are removed from active systems within 24 hours after processing on Free, or 72 hours on Premium. It also describes cloud storage and content moderation, so this is a cloud service rather than local-only processing. Save results before the retention window ends.Khanmigo is Khan Academy’s AI tutor and teaching assistant. Its tutoring approach uses questions and guided prompts to help learners reason through a problem, while teacher tools support lesson preparation, learning objectives, rubrics and exit tickets. Tutoring, writing practice, debate and coding feedback are available through the relevant learner or family plan. Free teacher access is separate from paid learner and parent access. Individual and family plans are listed at $4 per month or $44 per year, before applicable sales tax. A parent can enable Khanmigo for connected child accounts, review their interaction history and receive moderation alerts. Account, location and language eligibility apply; check the current signup requirements for your plan. Schools can request a separate Khanmigo District Tools quote. The district offering lists teacher and student access, school data, rostering, single sign-on through Clever SecureSync or ClassLink, implementation support and professional learning. A free teacher account does not automatically provide tutoring access to an entire class. For an evaluation, compare how the tutor guides a learner through a mistake, how an adult reviews the conversation, and whether the workflow fits the curriculum. Review AI suggestions before using them in teaching or assessed work. StudyMonkey offers a more direct question-and-explanation workflow, while Quizgecko focuses on practice material generated from your own sources.
