SciSpace alternative — for writing the thesis, not only reading the papers
SciSpace is built around finding and understanding literature: chat with a PDF, search a very large corpus, pull data out of many papers at once. Grongy starts where that ends — at the point a thesis has to be planned, drafted from those papers, and handed in as a formatted document.
No card required · every citation traceable to a real source
Three differences that change the daily work
Reading tools, or a writing workspace
SciSpace’s own pages lead with Chat with PDF, literature review across 280M+ papers, data extraction and a paraphraser. Grongy’s centre of gravity is the document: a chapter plan you approve, drafting from your library, an academic review, and an export your department will accept.
Metered by credits, or by the action
SciSpace runs on a credit balance — its own guide lists 100 credits a month on the free plan, 1,200 on Premium, 10,000 and 40,000 above that — spent faster when a query is computationally heavier. Grongy meters the actions you take, so what a chapter costs does not depend on how hard the model found it.
The document you hand in
Grongy exports a Word .docx with heading numbering, a table of contents, captions, footnotes and your page setup intact, and PDF, LaTeX and Markdown from the same draft — with the reference list built from the metadata of the sources you saved, in the style you chose.
How it works in practice
These two are not really the same category, and plenty of people use one to read and the other to write.
- 1
Keep reading where you read
If chatting with a PDF and extracting data is how you get through the literature, keep doing that. Nothing here asks you to stop.
- 2
Bring the shortlist across
Export the references you settled on as .bib or .ris and upload the PDFs. That becomes the library the drafting is allowed to cite.
- 3
Plan the chapters
Turn the topic and research question into a chapter-and-subsection plan, and change it until it matches what your department expects.
- 4
Draft, review, export
Draft each section from the library, check every citation against its source, then export the formatted document.
Side by side
Our side is what this product does. SciSpace’s side is what SciSpace itself published on its own product and credit-guide pages, as recorded in August 2026. We have deliberately not printed its prices: both sides change them, and a competitor price table would be wrong before it was useful.
- 1
What the product is for
SciSpace: an AI research assistant — search, read, summarise, extract. Grongy: a writing workspace for a thesis, dissertation, research paper or literature review.
- 2
Corpus
SciSpace: 280M+ papers, per its AI Writer page. Grongy: 250M+ records across OpenAlex, Crossref, DOAJ, PubMed and arXiv, plus Unpaywall for a legal open-access PDF.
- 3
How the writing is planned
SciSpace: autocomplete and citation insertion as you write. Grongy: a chapter-and-subsection plan you approve first, then section-by-section drafting from your library.
- 4
Metering
SciSpace: monthly credits (100 free, 1,200, 10,000 and 40,000 on the paid tiers, per its own credits guide), consumed faster by heavier queries. Grongy: per-action limits per plan.
- 5
The exported document
SciSpace: export with journal formatting templates. Grongy: Word .docx with heading numbers, table of contents, captions, footnotes and page setup, plus PDF, LaTeX and Markdown.

Tools we do not have
SciSpace also offers data extraction across many papers into a table, an AI detector, and journal submission templates. We offer none of those.
When SciSpace is the better pick
SciSpace does several things we do not do at all, and for some projects those things are the whole job.
- A systematic review where you need structured data pulled out of dozens of papers into one table.
- Formatting a manuscript to a specific journal’s template before submission.
- Reading at volume — chatting with a PDF is where SciSpace started, and it is good at it.
- You want an AI-detector tool. We do not offer one, and we do not build anything to defeat one either.
Questions before you start
Is Grongy AI a SciSpace alternative?
For the writing half, yes. For the reading half they are not the same product: SciSpace’s strength is searching, chatting with and extracting from papers, while Grongy plans and drafts the thesis from the papers you chose and exports the finished document. Using both is a perfectly sensible answer.
Which one writes the thesis?
Neither writes a thesis you can hand in. Grongy produces a first draft, section by section, from your own library, with an academic review that lists what still needs your attention — raw material to check, cut and rewrite. Your supervisor’s and your institution’s rules on AI-assisted work still apply.
Can I move my sources across?
Yes. Export the references as .bib or .ris and upload the PDFs. No account connection or password is involved on our side, and the PDFs stay readable inside the project.
Which one is cheaper?
SciSpace sells monthly credits; we sell per-action limits per plan. That makes a headline comparison misleading on its own, because one heavy query can cost several credits while a chapter here costs the same whatever the model made of it. Our full pricing is on this site, free plan first.
