Which AI detectors let you delete your submitted text? The 17 that state a deletion route, the 10 that say nothing is kept, and the 15 that state neither
Seventeen of the 72 AI detectors in the index state a route by which a user, a customer or an institution can have submitted text or media deleted, by the retention field of every card read 8 and 9 November 2026 in the data file, and 67 cards carry a retention clause of any kind. The routes range from a button to a contract: Winston AI's policy of 17 July 2026 says "If you delete a report, the associated submitted content is deleted from active storage" (gowinston.ai, read 8 November 2026), Grammarly Authorship's support article says report data can be deleted "at any time by clicking the trash bin icon for the respective document" (support.grammarly.com, read 9 November 2026), Turnitin's FAQ says "Customers can request a full deletion of their submissions; we cannot support partial data deletion requests to delete only the AI writing component" (guides.turnitin.com, read 8 November 2026), and Sensity's documentation exposes a DELETE call on submissions (docs.sensity.ai, read 9 November 2026). Ten more cards state that the input is not stored past the check, so there is nothing to delete, and 15 state neither a route nor a no-storage rule.
This page is about rights and routes, not periods. How long each vendor keeps text is the data retention ranking, and whether text is stored at all is the question on whether detectors store your text; neither table is repeated here. A card enters the first table when its retention field quotes a mechanism for removal, whether self-serve, by request, by API, by plan setting or by contract, and the route column names that mechanism in the vendor's own terms. Rows quote the clause, name the route and link the policy with its read date. This page is one of the questions answered from the index; the AI detector register carries every card.
| Detector | Deletion clause, as the card quotes it | Route | Source | Read date |
|---|---|---|---|---|

Which AI detectors let you delete submissions yourself?
Five, by a control in the product or the API. Winston AI deletes submitted content from active storage when the report is deleted and everything on account deletion (gowinston.ai, read 8 November 2026); Pangram deletes from its servers when an entry is removed from the dashboard history (pangram.com, read 8 November 2026); Grammarly Authorship offers a trash icon per document for report data, with shared reports held until the account is deleted (support.grammarly.com, read 9 November 2026); Sensity exposes a DELETE call on submissions (docs.sensity.ai, read 9 November 2026); and AIDetectPlus says tasks can be deleted at will, with a contact form as the second route (aidetectplus.com, read 9 November 2026). Three more prevent storage before it happens rather than deleting afterwards: Sapling's zero_retention flag and team setting (sapling.ai, read 8 November 2026), Resemble Detect's zero_retention_mode flag beside its 30-day request route (resemble.ai, read 9 November 2026), and TruthScan's zero data retention setting on Business plans and above, which its terms of 27 August 2026 limit to image and PDF submissions "with video or audio on request" (truthscan.com, read 9 November 2026). ZeroGPT states no-retention modes for API and enterprise customers without describing how they are switched on (zerogpt.com, read 8 November 2026).
Which detectors delete only on request or at contract end?
Eight. GPTZero deletes personal data on request and stores dashboard inputs but not API inputs (gptzero.me, read 8 November 2026). Hive adjusts its 14-day default "upon request", including to no retention (docs.thehive.ai, read 8 November 2026). Turnitin takes a full deletion request from the customer institution and will not delete the AI writing component alone, because the AI score is retained as part of the Similarity Report (guides.turnitin.com, read 8 November 2026), which means a student has no route of their own. Copyleaks and Codeleaks share a policy of 24 August 2026 in which direct customers contact support to opt out of model training, Shared Data Hub content can be removed, and an enterprise account is deleted within 90 days of the agreement ending (copyleaks.com, read 8 November 2026). Surfer deletes or returns Entrusted Data within 30 days of a written request or the contract's end, for contract customers, while stating nothing about text pasted into the free tool (surfer.ai, read 9 November 2026). Codequiry's route exists only for code submitted while the paid Rapid add-on is active; code submitted without it joins an anonymised cross-account corpus, is kept indefinitely after account closure and "cannot be deleted on request" (codequiry.com, read 9 November 2026). Pindrop's Pulse for Meetings DPA destroys personal data within 90 days after a 30-day return period (pindrop.com, read 9 November 2026).
Which detectors say there is nothing to delete?
Ten state that the submitted text or media is not kept past the check, and in three of the ten a second document says something else. Scribbr ("we do not store or share your data", scribbr.com, read 8 November 2026), Undetectable AI ("Your text is never stored", undetectable.ai, read 9 November 2026), AI or Not ("processed and deleted immediately after inference", docs.aiornot.com, read 9 November 2026), Sightengine ("Your content is deleted once it has been processed", sightengine.com, read 9 November 2026), WasItAI ("We do not store submitted images beyond the duration required", wasitai.com, read 9 November 2026), Illuminarty ("kept only for the duration necessary", illuminarty.ai, read 9 November 2026) and SynthID ("the original media files are immediately deleted", with a digital signature held 24 hours, synthid.com, read 9 November 2026) make the statement once. Phrasly's detector page says text is "deleted immediately after analysis" while its terms of 12 October 2026 grant a perpetual licence over Contributions (phrasly.ai, read 8 November 2026); Smodin's detector page says text is "never stored" while its terms grant a perpetual licence over User Content (smodin.io, read 9 November 2026); and Quetext's detector page says scanned content "is not stored, saved, or used to train any models" while section 6.1 of its policy of 14 October 2026 allows User Content in AI training with an opt-out by email to privacy@quetext.com (quetext.com, read 9 November 2026).
Cards whose retention field states the input is not kept
| Detector | Not-stored statement, as the card quotes it | Second document on the card | Source | Read date |

| Phrasly | "deleted immediately after analysis. We don't store your writing" | Terms of 12 October 2026: perpetual licence over Contributions | phrasly.ai | 8 November 2026 |
| Undetectable AI | "Your text is never stored or used to train models" | Privacy policy of 18 March 2023 does not mention submitted text | undetectable.ai | 9 November 2026 |
| AI or Not | "uploaded media are processed and deleted immediately after inference"; "No data stored" | Live Voice logs retained up to 31 days | docs.aiornot.com | 9 November 2026 |
| SynthID | "the original media files are immediately deleted" | A digital signature of the media kept 24 hours for quota enforcement | synthid.com | 9 November 2026 |
| Smodin | "Your text is never stored or shared"; "We also never store your files" | Terms: perpetual, irrevocable licence over User Content | smodin.io | 9 November 2026 |
| Quetext | "Your scanned content is not stored, saved, or used to train any models" | Policy of 14 October 2026, section 6.1: User Content may be used in AI training; opt out by email | quetext.com | 9 November 2026 |
| Sightengine | "Your content is deleted once it has been processed, unless you ask us to keep it or the law requires us to" | Demo files kept as logs deleted after a limited period; Feedback API content kept | sightengine.com | 9 November 2026 |
| WasItAI | "We do not store submitted images beyond the duration required to complete the analysis request" | Log data deleted after 90 days; account data within 30 days of account deletion | wasitai.com | 9 November 2026 |
| Illuminarty | "Any image uploaded to our server will be kept only for the duration necessary to provide our service to you" | Policy of 16 November 2022; no period for text submissions | illuminarty.ai | 9 November 2026 |
Statements as the retention field of each card quotes them, read on the date shown. The other 15 cards, read 9 November 2026 in the data file, state neither a deletion route nor a no-storage rule: 10 carry a retention clause that gives a period or a purpose and no mechanism (JustDone, Originality.ai, whose policy of 17 June 2026 offers an opt-out from model training but no deletion route, Proofademic, Walter Writes, Reality Defender, Writer, Turnitin Clarity, BrandWell, Compilatio and Deepware), and 5 carry no retention field, of which GLTR, the GPT-2 Output Detector and DetectGPT run on the reader's own machine and QuillBot and Grammarly state no retention terms on the pages read.
A deletion route on a privacy page is a promise about one copy, and Turnitin, Codequiry and the two perpetual-licence terms show how a second document can narrow it.
Questions about deleting AI detector submissions

17 of 42 cards state a route, read 8 and 9 November 2026: 5 by a control in the product or API (Winston AI, Pangram, Grammarly Authorship, Sensity, AIDetectPlus), 4 by a no-storage flag or plan setting (Sapling, Resemble Detect, TruthScan, ZeroGPT) and 8 by request or at contract end (GPTZero, Hive, Turnitin, Copyleaks, Codeleaks, Surfer, Codequiry, Pindrop). 10 more say the input is not kept.
Can a student delete their submission from Turnitin?
0 student-facing routes: Turnitin's FAQ, read 8 November 2026, says "Customers can request a full deletion of their submissions", the customer being the institution, and "we cannot support partial data deletion requests to delete only the AI writing component" (guides.turnitin.com).
Does GPTZero keep the text I check?
