AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.

AI file sorter that renames and files your documents from a plain-English prompt
Describe the result you want in plain English and Sortio plans the renames and folder moves for you.
Reads inside each file to build meaningful names such as date, vendor, amount, or person, instead of leaving cryptic originals.
Every move is shown before it happens, and any sorting pass can be rolled back completely.
Files stay on your machine, with local LLM and bring-your-own-key options on every plan.
