DescriptionAudioShake separates an existing recording into sources such as vocals, instruments, dialogue, music and effects. It also offers speech cleanup, speaker separation, lyric transcription and word-level lyric alignment. Use those outputs in editing, dubbing, remixing or audio analysis, and listen for leakage and changed sounds before delivery. Its lyric transcription is not a general-purpose speech-to-text service; separated speech can instead feed a dedicated transcription workflow. The developer API includes 10 credits on signup. Usage is billed per source-audio minute for each target model, rounding the duration up to the next minute. A 2 minute 10 second recording processed by vocals and instrumental models at one credit per minute each costs six credits. Instrument stems and lyric transcription/alignment cost one credit per minute; dialogue, effects and speech denoise cost 1.5, dereverb two, multi-voice and music removal ten, and music detection 0.5. Credit rates are not dollar prices. Dereverb also reduces noise, so avoid automatically paying for both cleanup models when one meets the task. Choose AudioShake Live for its professional web workflow, Indie for its artist-oriented route, the API for asynchronous jobs and batches, or a separately licensed Local Inference SDK for on-device or self-hosted integration. Check the target model's input limits: multi-voice accepts at most 1.5 hours, while lyric transcription and alignment accept at most 45 minutes. Pilot the required source material and integration before committing to a production pipeline. AudioShake's August 2026 terms identify Audioshake, Inc. Customers retain content ownership and must have the rights to upload and process it. The agreement permits service improvement and development uses of content, while promising not to sell it or use it to train models designed to generate new original musical compositions or sound recordings. That is a narrower promise than a ban on all model training. Confirm the applicable Order Form for third-party or service-bureau integrations and agree retention requirements for confidential audio.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.
