AudioStrip vs EssayGrader
Side-by-side comparison · Updated October 2026
| Description | AudioStrip is a web service for separating vocals and instrumentals with trained AI, reducing noise in speech, and mastering recordings. It also offers key and BPM detection. It is a useful option to compare when preparing a practice track, checking a mix or extracting material you have permission to reuse. Source separation can leave vocal remnants and other artifacts; the useful test is how the output sounds in your project, not whether a marketing example sounds clean. Its free pricing table lists three isolations, three masters and three enhancements per month. Free uploads are limited to 50 MB and eight minutes, with MP3 output. There is a discrepancy to check: the FAQ still says five free extractions per month. Budget for the pricing table's lower allowance and confirm the current quota in the service before planning a larger job. The FAQ lists WAV, MP3, OGG, M4A, WMA and FLAC inputs, and recommends starting from a good-quality WAV or FLAC source when available. The Premium pricing card currently displays £5.99 per month as a 25% offer against £7.99. It advertises unlimited isolations, masters and enhancements, batch uploads, files emailed to you, and WAV, FLAC or MP3 output. Limits rise to 200 MB and 20 minutes per upload. Confirm the price charged at checkout and on renewal: this listing reports a promotional display, not a tested purchase or a guaranteed permanent rate. The site advertises a 15-day Premium trial; the terms restrict trials to first-time Premium customers. For a small evaluation, choose a recording you are authorized to process and decide which part you need to keep. Use isolation for vocals and backing music, enhancement for speech noise, or mastering for a finished mix. Listen for voice remnants, watery or metallic textures, missing transients and unwanted changes to the instruments. Keep the original file and judge the result both alone and in the intended mix. Paying for more output formats or faster processing does not guarantee that every song will separate well. AudioStrip's free 15–60 minute estimate and Premium speed claims are vendor estimates, not measurements from this review. Compared with AudioAlter, AudioStrip focuses on learned separation and offers a paid batch workflow. AudioAlter provides individual effects, conversion and analysis tools, with OOPS stereo subtraction for vocal reduction. The methods solve overlapping but different problems. Neither processing method grants rights to recordings or musical compositions you do not own. AudioStrip Ltd is the operator named in the terms, which set an 18+ service requirement. The terms say the company does not claim ownership of input or output recordings and will not use input recordings to train or improve AI or machine-learning models. Those are provider policy statements, not an independent audit. Its privacy policy separately describes account, analytics and cookie data; no fixed audio-file deletion deadline is confirmed here. Premium renews monthly unless canceled, and the terms say access ends on unsubscribe. Check the cancellation and trial conditions before starting, especially if you only need one batch. | 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. |
