# LabCanvas > LabCanvas is a browser-based workspace for scientific visuals. It combines a vector figure editor, a presentation maker, a research poster designer, a 3D studio, a protein structure viewer and a graphing and statistics app, with journal-ready export and an AI assistant. The apps are free to use with an account (one design of each kind, no downloads); LabCanvas Pro (US$19 a month or US$199 a year) adds downloads in every format, unlimited designs and monthly AI credits. The website and the free tools at /tools need no account. Designs are kept in the user's browser and, optionally, in the user's private cloud folder. LabCanvas runs entirely in the web browser. Its apps share one design library and clipboard, can be installed as desktop apps, and can be driven by AI models: through a built-in assistant (Claude and other leading models, with monthly AI credits) or through an MCP server with 106 tools. ## Apps - [Figure editor](https://www.labcanvas.com/editor.html): Illustrator-level vector tools made for scientific figures.

It also works with distances typed in by hand. - [ELISA standard curve analyzer (4PL)](https://www.labcanvas.com/tools/elisa-standard-curve-analyzer): Enter your standards (concentration and OD, with replicates) and your samples’ ODs and dilution factors. The analyzer fits a four-parameter logistic (4PL) curve, or a linear or log-log line, subtracts the blank, and calculates each sample’s concentration, flagging values outside the standard range. You get R², the fitted parameters, a chart and a CSV. ## Pages - [Features](https://www.labcanvas.com/features): Everything in the eight apps - [Pricing](https://www.labcanvas.com/pricing): The free plan (every app, one design of each kind) and LabCanvas Pro (downloads, unlimited designs, AI), monthly or yearly - [Gallery](https://www.labcanvas.com/gallery): Editable scientific illustrations - [Tutorials](https://www.labcanvas.com/tutorials): Step-by-step guides - [Documentation](https://www.labcanvas.com/documentation): How each app works, export, shortcuts - [About us](https://www.labcanvas.com/about-us): The company and team behind LabCanvas - [Editorial guidelines](https://www.labcanvas.com/editorial-guidelines): How content is written and checked - [Contact](https://www.labcanvas.com/contact): Email and address - [Sitemap](https://www.labcanvas.com/sitemap): All pages - [Privacy Policy](https://www.labcanvas.com/privacy): How data is handled - [Terms of Service](https://www.labcanvas.com/terms): Terms of use ## Guides - [What is LabCanvas? One workspace for scientific illustration, data and presentation](https://www.labcanvas.com/blog/what-is-labcanvas): A guide to LabCanvas: ten connected apps for figures, molecules, 3D crystals, graphs, slides and posters, the workflows between them, ready-made templates, and why one editable canvas makes scientific illustration faster to learn and easier to change. ## FAQ - **What is LabCanvas?** LabCanvas is a browser-based workspace for scientific visuals. It combines a vector figure editor, a presentation maker, a research poster designer, a 3D studio, a protein structure viewer and a graphing and statistics app, with journal-ready export and an AI assistant. - **How much does LabCanvas cost?** Every app is free to use with an account, with one design of each kind; downloading and exporting are part of LabCanvas Pro, paid monthly or yearly (see the pricing page for the price in your country). LabCanvas Pro also gives unlimited designs and a monthly allowance of AI credits for the assistant. Choose monthly or yearly and pay securely through Dodo Payments; cancel any time. The website and the free tools at /tools need no account and no payment. - **Where are my designs stored?** In your browser’s storage (IndexedDB) on your own device, and, with cloud saving on (the default for new designs), in your own private folder in LabCanvas cloud, so they open on any computer. You can switch cloud saving off for any design, and File › Save a copy keeps a portable .labcanvas file. - **Which export formats and resolutions are supported?** PNG, JPEG, WebP, TIFF, PDF and SVG. You set the physical width in millimetres and the resolution (for example 300, 600 or 1200 dpi); PNG and TIFF files record their DPI. Presentations export as one vector PDF. - **Can I make a conference poster?** Yes. LabCanvas Poster starts from a template (A0 or A1 portrait, 48 × 36 in landscape, a billboard-style #betterposter layout and more) built from blocks: title, sections, figures, a key finding, a big number, references and a QR code. Drag a block to another column or between two others and the columns re-stack; resize it and the text re-flows. Themes restyle every block at once, and the poster exports as a vector PDF at its exact printed size. - **Can I write LaTeX equations?** Yes. Objects › Equation typesets LaTeX, including AMS environments and chemistry with \ce{…}, into vector outlines that stay sharp in PDF and SVG. Double-click an equation to edit its LaTeX later. - **How do I visualise a protein from the PDB?** Open the Protein viewer, enter a PDB ID such as 1CRN or 4HHB, pick a style (cartoon, surface, ball-and-stick…) and a colouring, select residues on the sequence bar to highlight or restyle them, then download a PNG or add it to your figure. - **Which AI models can the assistant use?** The assistant runs on leading models such as Anthropic Claude, chosen and set up by LabCanvas: there is no API key to paste. Each LabCanvas Pro plan includes monthly AI credits; you can attach images and PDFs to your messages, and your chats are saved to your account. The assistant edits through the same actions as the toolbar, so every change can be undone. - **What is the LabCanvas MCP server?** LabCanvas includes a Model Context Protocol (MCP) server with 97 tools, so AI agents such as Claude Desktop or Claude Code can create and edit figures, slides, posters, graphs, 3D scenes and optical setups in your open LabCanvas apps. - **Can I install LabCanvas as an app?** Yes. The figure editor, Slides, the 3D Studio, the Protein viewer and the Graph app can each be installed from the browser and opened like desktop apps. ## Optional - [Full text of the site for language models](https://www.labcanvas.com/llms-full.txt) - [Blog RSS feed](https://www.labcanvas.com/blog/feed.xml) - [Sitemap](https://www.labcanvas.com/sitemap.xml)
