Honest AI help
Ask Cowriter to make a draft clearer or more formal. Removed words show in red, new words in green, and nothing changes until you accept.
Your own words
Diglot underlines each issue and lists it beside the text: what is wrong, why, and the fix.
Before you submit
Run four checks at once: proofreading, source quality, citation gaps and a peer review of the whole draft, the way a careful reader would before you submit.
Cowriter skills
Cowriter has 30+ skills you call with a slash. Pick a text, pick a skill, then switch between Fluent AI on Free and Native AI on Pro.
Your draft
Many researches shows that students which use social media more than three hours per day have lower grades. In our opinion this is because the constant notifications make difficult to concentrate, so the information is not stay in the memory.
We propose to migrate our reporting to the new platform in Q1. This will reduce costs a lot and the team will be more productive, because the old system is very slow and nobody likes it.
We are very sorry for the delay, it was not our fault but the supplier one. We will try to send you the goods until Friday, please be patient with us and don’t cancel the order.

FAQ
It reports an estimate. Alongside the similarity check, Turnitin returns the share of a document its model considers likely AI-generated. The number describes statistical patterns — it names no tool, no prompt and no source — and Turnitin itself tells institutions to treat it as a starting point for a conversation, not as evidence.
No. We do not rewrite text to fool a detector, and we never will — that advice is worthless and it hurts honest writers most. Diglot records how you actually wrote the document, so you have process evidence if a score is ever questioned.
Detectors score how even and predictable the prose is. Careful formal writing is even too. A Stanford study found AI detectors falsely flagged 61% of TOEFL essays by non-native English speakers while classifying US-born students almost perfectly (Liang et al., Patterns, 2023).
Signals from your writing process inside the editor: active writing time, editing sessions, revisions, accepted suggestions and cited sources, sealed with an ed25519 signature and a public verification link. It is supporting evidence of how the work developed; no one can guarantee that a university will accept it as conclusive proof.
Yes. Every Diglot account, including the free plan, can create and export Authorship Certificates. Anyone you share it with can verify it in a browser without an account. Paid plans raise writing and AI limits — see the pricing page.
For the past document the certificate cannot be created retroactively — it records writing as it happens. Start with the flagged-as-AI playbook: gather version history, drafts and notes, then write your next document in Diglot so the evidence exists before anyone asks.
Never. Your drafts are private, encrypted in transit and at rest, and are not used to train public or commercial models.
