Resoomer vs SciSummary (2026): which should you pick?

Pick Resoomer if

• Fits if you want a quick summary of an article with no sign-up
• Works for rewording or translating a passage in the browser

Look elsewhere if

• Skip it if you want answers with sources, as the summaries come with no citations
• Not for you if you want to manage papers or citations, because it does neither
• Too light for chatting with a document, as it is not a chat assistant
• Watch out: texts are deleted after processing, so export or save results yourself

Pick SciSummary if

• Fits if you read scientific papers and want the figures explained
• Works for someone who searches PubMed and arXiv and wants one library

Look elsewhere if

• Skip it if you want a free plan, as only a 7-day capped trial exists
• Pricey if you read the vendor's own pages: they disagree between $12.50 and $4 a month
• Watch out: the trial caps summaries at 30,000 words, 5 figures and 100 chat messages
• Watch out: uploads are capped at 200 MB, and there's no desktop or mobile app

Resoomer

• It is a set of single-purpose text tools, not a chat assistant, and it does not manage a library of papers or citations.
• Texts are deleted after processing, so results must be exported or saved by the user.
• The site gives no sources or citations for the summaries it produces.
• The site's page code still carries a monthly premium price variable, but no paid plan is shown on any page read.

SciSummary

• The homepage shows $12.50 a month billed yearly and $15 billed monthly, but the site's llms.txt file lists $4 and $7 a month, so the vendor's own pages disagree.
• The 7-day trial caps summaries at 30,000 words, 5 figures and 100 chat messages; non-AI features are free without a card.
• Only a web version is described, with no desktop or mobile app.
• Uploads are capped at 200 MB per file, and the FAQ says larger files may fail.
