Oleafly vs Verbosus

Oleafly is a free desktop workspace for writing technical documents such as papers, theses, and resumes. It brings writing, PDF preview, references, and an optional AI assistant together, and supports LaTeX, Typst, and Markdown projects. Research search covers alphaXiv and OpenAlex, citations can be checked against Crossref, and reference libraries can be imported from BibTeX, RIS, EndNote XML, and Zotero RDF. Local spelling and grammar checks use Hunspell and Harper, with a focus on prose rather than LaTeX commands and mathematics. Writing, local compilation, PDF review, and proofreading work offline without AI, once packages, fonts, and tools are downloaded. Projects can be imported from folders or ZIPs and exported as PDF, DOCX, HTML, Markdown, or source ZIP files. GitHub push and pull and Git-based collaboration are supported, but real-time co-editing, comments, and managed sync are not available. Oleafly is open source under AGPL-3.0 for macOS, Windows, and Linux. The desktop app has no subscription; paid AI providers may charge for usage.

Verbosus offers VerbTeX for creating and managing LaTeX projects on iPhone, iPad, Android, and the web. Choose local mode to keep.tex documents on a device or cloud mode to synchronize projects with Verbosus; cloud mode also has a web interface. Local mode supports offline editing and can compile offline when that option is enabled in Settings. PDF generation supports PdfLaTeX, XeLaTeX, and LuaLaTeX, while bibliographies can be managed with BibTeX or Biber. The editor includes syntax highlighting, line numbers, autosave, custom keyboard shortcuts, and inverse search from a PDF to its.tex file. Local integrations include Dropbox, Box, Git, iCloud, Zotero, and Mendeley. The app lists an AI assistant for ChatGPT and Claude. The free plan costs nothing and allows two projects in each mode, two documents per project, and two uploads per local project. Two-factor authentication is listed for cloud mode in combination with Copiosus.
