Three research skills
Diglot gives Cowriter three research skills. /library answers from the papers you have saved, /research returns a cited answer from the open web, and /deep-research plans the question, searches 9 scholarly databases and the web, and writes a report with numbered references. Every answer links to its sources, so each claim can be checked.
/library Free · 40 a month
Ask Library
Question the sources you have saved to your Library. Answers stay grounded in your own research. Free lets you upload 150 PDF pages a month and keep up to 25 sources; Spark raises the upload allowance to 200 pages a month.
/research Spark and up
Web Answer
Search the open web for a focused, cited answer when your library does not cover the question yet. 100 a month on Spark, with no monthly cap on Pro and Max.
/deep-research Free · 1 a month

From report to draft
Ask a research question. Deep Research searches scholarly databases and your library, then writes a report with numbered references as a document in your workspace.
Citation integrity
/citation-gaps marks the sentences that make a claim without a source. /check-sources looks up each DOI, and /find-source suggests papers you can add.
Your own PDF library
Upload the PDFs you are writing from. /library answers from them, names the page, and drops the fact into your paragraph with the citation.
Autocomplete and citations
Pause at the end of a sentence and Diglot suggests the next one in grey. Press Tab to keep it, then cite the paragraph in APA, MLA, Chicago or any of 10,852 CSL styles.
Peer review
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

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.

The Transformer replaced recurrence with attention alone , and pre-trained encoders such as BERT carried the idea to language understanding . Attention mechanisms first improved neural machine translation .

FAQ
1 report a month on Free with no credit card, 5 on Spark, 30 on Pro and 150 on Max. Every report opens as a document in your workspace.
Deep Research is an agentic research workflow for academic and evidence-heavy questions. It plans the query, searches scholarly databases and the open web, and returns a structured report with linked sources that you can inspect and save to your Diglot Library.
The scholarly discovery layer federates OpenAlex, Semantic Scholar, Crossref, PubMed, Europe PMC, ERIC, DOAJ, arXiv and OpenAIRE. Provider availability can change, and no database guarantees complete coverage of a field.
No. The report helps you discover and organize evidence, but you should open the original paper and verify every claim, method and citation before using it in submitted work.
Ask Library searches only the sources you have already saved to your Library (paid plans can also upload PDFs). Deep Research searches outside your workspace to discover new scholarly and web sources, then lets you save the useful ones back into Library.
Use it as a research map: identify papers, competing findings, methods and open questions, then read the originals and write the synthesis yourself. Diglot keeps the sources, citations and draft connected in the same workspace.
