CoGrader vs EssayGrader
Side-by-side comparison · Updated September 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. | EssayGrader is a browser-based assessment assistant for teachers reviewing student writing. Educators can choose or upload a rubric, import assignments, review suggested scores and feedback, and edit the results before sharing them. The current service includes standards-aligned rubrics, handwritten essay processing, revision comparisons and classroom writing insights. Teacher review remains essential: a suggested score or detection flag is not a final educational judgment. The current pricing table lists a free Basic plan with 50 essays graded and 50 essays summarized per month, with a 1,000-word limit per essay. The homepage separately advertises 100 essays free without specifying a recurring allowance. Use the plan table's 50-per-month limit for planning and confirm any introductory allocation in the account; do not assume the homepage offer means 100 essays every month. The current pricing table no longer lists a Lite tier. Pro costs $19.99 per month with monthly billing, or an advertised $14.99 per month when annual billing is selected. It includes 350 essays per month, a 3,500-word limit per essay, AI-writing and plagiarism checks for 350 essays, and native Google Classroom, Canvas and Schoology integrations. Premium costs $49.99 monthly or an advertised $34.99 per month with annual billing, with 800 essays per month and an 8,000-word limit. The calculated annual equivalents are $179.88 for Pro and $419.88 for Premium; the terms specify USD and exclude applicable taxes. Confirm the final checkout amount and billing period. The School District / Higher-Ed option is quoted for 25 or more users. It offers a mix of Pro and Premium licenses, administration, teacher and administrator training, institutional analytics and data-agreement support. This is not an unlimited individual plan. Match the license mix to the number and length of assignments each educator handles. For a useful evaluation, use permitted sample work, a clear rubric and a small set of essays you have already assessed. Check suggested scores against the relevant criteria, verify that comments accurately describe the text, and edit feedback for the student's needs. For handwritten work, inspect the transcription before judging the feedback. Compare revision drafts to see whether the advice helps identify specific improvements. Confirm LMS access on the chosen plan before depending on automatic import and return of grades. The official FAQ states that student submissions are not used to train AI models. Its privacy policy and terms require users to remove or anonymize student and minor identifiers, including metadata, before uploading work. They also describe third-party processing, so a no-training statement does not mean no provider ever processes the data. The April 2026 privacy policy describes deletion within 60 days of an account-deletion request, subject to legal or contractual exceptions; the older terms also mention storage for up to 180 days after termination. Resolve the applicable retention commitments with the provider before an institutional rollout. Tech Nest Ventures Inc. is the service provider named in EssayGrader's terms and privacy policy. Compare CoGrader for another teacher-facing rubric and feedback workflow, using the same assignment sample and review criteria. EssayGrader's terms make subscriptions recurring and generally do not promise refunds; check cancellation and institutional notice requirements before purchasing. |
