Why this tool?
- Converts handwritten notes and images directly into clean LaTeX code — no manual transcription
- Free standalone Image-to-LaTeX and Excel-to-LaTeX converters lower the barrier to try before subscribing
- Chrome extension brings LaTeX assistance into the browser workflow without switching apps
- Covers the full academic writing cycle: input conversion, abstract generation, citation management, and formatting in one tool
When NOT to use?
- You write outside academia or technical research. Underleaf's toolset — abstract generation, citation management, LaTeX output — is built specifically for scholarly work; bloggers, copywriters, and business writers will find little of practical value here.
- Your institution or journal does not accept LaTeX submissions. If your workflow ends in a Word document or Google Doc, converting output back from LaTeX introduces unnecessary friction and formatting risk.
- You need robust real-time co-authoring. Teams that rely heavily on simultaneous multi-user editing, inline commenting, and change tracking (as in Overleaf or Google Docs) will find Underleaf's collaboration features limited by comparison.
- You are a complete LaTeX beginner who needs structured learning. Underleaf automates LaTeX generation but does not teach the underlying language; if understanding LaTeX is the goal, dedicated tutorials or textbooks are a better starting point.
- Your organization has strict data-residency or confidentiality requirements. Uploading sensitive research data, unpublished manuscripts, or proprietary datasets to a cloud-based AI service may conflict with institutional data-governance policies or grant agreements.
Underleaf is an AI-powered academic writing platform built specifically for researchers, professors, and students who work with LaTeX. Available at underleaf.ai, it combines document conversion, LaTeX code generation, and academic writing assistance into a single browser-based tool. The platform targets a gap between general-purpose AI writing assistants and traditional LaTeX editors by focusing exclusively on scholarly document workflows.
Core Features and Conversion Tools
Underleaf's primary strength lies in converting various input formats into clean LaTeX code. The platform handles:
- Handwritten notes to LaTeX — upload photos of handwritten equations or text, and the AI generates corresponding LaTeX markup
- Image-to-LaTeX conversion — extracts mathematical formulas and structured content from screenshots or scanned documents
- Excel-to-LaTeX tables — converts spreadsheet data into properly formatted LaTeX table environments
- PDF parsing — pulls content from existing PDF documents for LaTeX reformatting
Both the Image-to-LaTeX and Excel-to-LaTeX converters are available as free standalone tools, which lets users evaluate the conversion quality before committing to a subscription. A Chrome extension is also available for quick conversions without leaving the browser.
Academic Writing Assistance
Beyond format conversion, Underleaf provides several AI-driven writing features tailored to academic contexts. These include abstract generation, citation management, and document formatting according to common journal and conference templates. The editor supports dark mode and offers what the platform calls "smart features" designed to reduce the time spent on formatting and structural tasks.
For researchers who regularly submit to journals with strict formatting requirements, having AI-assisted template compliance can reduce rejection risk from formatting errors. The citation management integration helps maintain bibliography consistency across longer documents like dissertations or multi-author papers.
Pricing and Plans
Underleaf uses a tiered subscription model with three levels:
- Essentials — $4.99 per month, covering basic conversion and writing features
- Pro — $9.99 per month, with expanded AI capabilities and higher usage limits
- Team — custom pricing for research groups and academic departments requiring multi-user access
At $4.99–$9.99 per month, Underleaf sits in a lower price range compared to comprehensive reference managers or full academic writing suites. The free standalone converters provide a no-cost entry point for users who only need occasional LaTeX conversion without the broader writing assistance.
Limitations and Considerations
Underleaf occupies a niche that overlaps with Overleaf (the widely used collaborative LaTeX editor) in name and audience, though the two platforms differ significantly. Overleaf provides a full cloud-based LaTeX compilation environment with real-time collaboration, while Underleaf focuses on AI-assisted conversion and writing support. Users looking for a complete LaTeX editing and compilation environment may still need Overleaf or a local TeX distribution alongside Underleaf. The platform is best suited as a complementary tool rather than a full replacement for established LaTeX workflows.
For academics and students who frequently convert handwritten work or non-LaTeX documents into properly formatted papers, Underleaf offers a focused set of conversion and writing tools at a reasonable price point. The free converters make it straightforward to test the core technology before subscribing, which is a practical approach for budget-conscious researchers evaluating their options among LaTeX and academic writing tools.

- Is Underleaf a good alternative to Overleaf for LaTeX editing?
- Underleaf complements or extends the LaTeX workflow by adding AI-powered features such as automatic conversion from images, PDFs, and spreadsheets, plus academic writing assistance like abstract drafting and citation management. While Overleaf focuses on collaborative LaTeX editing, Underleaf specifically targets AI-assisted content generation and document conversion for academic users.
- Can Underleaf convert Excel spreadsheets to LaTeX tables?
- Yes, Underleaf includes a dedicated Excel-to-LaTeX converter that transforms spreadsheet data into properly formatted LaTeX table code. This feature is available as a free standalone tool, making it easy for researchers to embed data tables into academic papers without manual LaTeX coding.
