CoGrader vs Draw Things
Side-by-side comparison · Updated October 2026
| Description | CoGrader is a teacher-facing AI grading assistant for essays and other open-ended assignments. It uses a selected or custom rubric to draft grades and feedback that educators can review and edit before returning work. Its useful role is helping a teacher organize assessment and feedback; it does not establish that a grade is correct, unbiased or suitable for a particular student without human review. The free Starter plan includes 100 student submissions per month and rubric creation and sharing. The pricing page also advertises 90 days of premium access, which is a temporary benefit rather than unlimited free access to paid features. Standard includes 350 submissions per month, handwritten assignments, grammar checking and a class-performance dashboard. It costs $19 per month on monthly billing or an advertised $15 per month billed annually. The annual equivalent is $180 before any applicable additions, calculated as $15 multiplied by 12; confirm the actual checkout total before paying. Schools and Districts plans use a custom quote and advertise unlimited submissions, shared rubric libraries, administration, institutional analytics and training. Higher Ed and Enterprise also use a custom quote, with API access, custom LMS connections and roles among the listed options. Choose a plan around submission volume, the review process and the integrations your institution actually needs, rather than assuming an individual subscription includes enterprise access. To evaluate CoGrader, begin with a rubric that defines each criterion and the evidence needed for each score. Try a small, permitted sample of work you have already assessed, compare the suggested results with your own reasoning, and revise unclear rubric language. Check whether each comment refers accurately to the student's work and gives an actionable next step. Review accommodations, language-learning needs and subject-specific expectations before finalizing feedback. A class dashboard can help identify topics to revisit; it should not replace the teacher's judgment about individual learning needs. Google Classroom integration is described as available to all users. The pricing FAQ places full Canvas and Schoology integration in school or district subscriptions, although the plan cards also display those platforms elsewhere. Confirm the exact integration and account entitlement you need. Other LMS workflows may use file import and export. The vendor also advertises plagiarism and AI-writing detection, but its plan card and FAQ disagree about AI-detection access. Confirm the selected plan's access, and treat a flag as a reason to review the evidence rather than proof of misconduct. CoGrader's privacy policy says teachers provide assignment questions, rubrics and student answers, and that student grading data is not used to train its AI models. It says third-party AI providers may not train on that data and identifies OpenAI OpCo, LLC as a provider receiving anonymized grading information. The policy also allows anonymized aggregate information to improve the service and does not give one fixed deletion deadline. Follow your school's authorization and data-handling process before uploading student work; a vendor policy is a statement of practice, not an independent security assessment. CoGrader is most relevant when an educator needs rubric-based feedback at a recurring classroom workload. Compare EssayGrader using the same sample rubric, feedback-review steps, submission allowance and data requirements. The terms describe a refund window within 14 days of an initial subscription purchase; that is separate from the free plan's advertised premium-access period. Review billing and cancellation terms before subscribing. | Draw Things is a local AI image and video creation app for iPhone, iPad and Mac. It suits creators who want to choose their models, work with existing images and keep local generation on their own Apple hardware. Its free local workflow does not require a subscription or token allowance. Download the app and the models you need before relying on offline access; optional Cloud Compute is a separate workflow with account and network requirements. Start with a text prompt or an existing image, choose a compatible model and refine the result. The official app listing describes image-to-image, inpainting, outpainting, ControlNet, pose editing and an infinite canvas. You can import community diffusion models and LoRAs, or train LoRAs on-device. The current product also supports image-to-video workflows. These options make it useful for testing visual concepts and editing selected regions, but model choice, available memory and device performance affect what you can practically generate. We have not benchmarked rendering speed or output quality. The provider lists a Free Edition for local compute and a free Community account for Cloud Compute and Lab Hours. Draw Things+ is advertised at US$8.99 per month, with higher cloud limits, custom LoRA uploads and additional cloud features. Numeric cloud quotas are not published on the reviewed pricing page. The US App Store also lists optional Boost Bundles, but check their current in-app entitlements before buying. Enterprise access is available by contacting the provider for organization deployment, on-premise inference and application integration; no public enterprise price is shown. Local and cloud privacy should be considered separately. Draw Things describes local creation as offline and says most creations and data can stay on the device. Its policy documents an optional Apple sign-in identifier for Cloud Compute and subscription transaction information for paid access. Uploaded LoRAs are stored on cloud servers until you delete them or the account. The app release history also mentions Google sign-in, while the policy still describes Apple sign-in; check the current account flow rather than assuming that every sign-in method has identical data handling. The policy says it does not use third-party analytics or advertising frameworks for tracking. Use the official Apple listing for Draw Things, Inc., app ID 6444050820, to distinguish it from similarly named apps. The US listing carries an 18+ age rating. For a first project, use a non-sensitive reference image, confirm the chosen model fits your device and test a modest output before attempting larger images or video. Review imported model, LoRA and source-image licenses before commercial work: free software access does not itself grant rights to every model or generated asset. Draw Things is the stronger fit here when model control and local editing matter; compare a simpler fixed-model generator if you mainly want to turn short text prompts into images. |
