# Zlo > Zlo (https://www.zloapp.com) is a platform to make and publish pages, apps, games, link collections, courses, assignments, portfolios and challenges, and share each with one link. Work is organized as projects; each project has a purpose and holds items; each item is published as its own page. ## What you can do - Notes: Write documents, collect references, organize ideas and publish them. For example: Publish research notes; Share a reference collection; Put a document online. - Links: Collect web links as visual cards and share curated collections. For example: Product recommendations with affiliate links; A shopping list; A resource list. - Hobby: Document personal interests, experiments and creative work as they happen. For example: A gardening log; A build diary; Weekend experiments. - App: Make, import and publish web pages, mini apps, games and interactive tools. For example: Host an AI-made website; Publish a browser game; Share a calculator. - Live Project: Share an ongoing project, post what you need, and collect responses. For example: Find a 3D modeler or designer; Post a requirement; Show progress and milestones. - Assignment: Set tasks or exercises, collect submissions and review them. For example: Homework online; Collect worksheet answers; A design exercise. - Course: Organize lessons, materials and exercises into a course. For example: An online course; A syllabus with chapters; Step-by-step tutorials. - Portfolio: Show finished work, skills and projects in one place. For example: A design portfolio; A project showcase; Work samples to share. - Challenge: Publish a brief, invite entries, and show the results. For example: Run a design competition; A coding challenge; Collect contest entries. ### One subject, many ways: building an RC car Each of these is its own project, joined by one subject: - Notes: Research, specifications and design notes - Links: Parts, electronics and where to buy them - Hobby: Test drives and experiments - App: An interactive tool to configure the car - Live Project: Progress, milestones, and finding a 3D modeler - Assignment: A steering-mechanism design exercise - Course: How to design a 3D-printable RC car - Portfolio: The finished car - Challenge: Invite designers to make a better car body ## How it works 1. Make: Create a project, pick its purpose, and add items: write, paste a page made in an AI chat, upload files, or sync a folder. 2. Publish: Press Flash. Each item gets its own public page and link, and appears on the Wall. 3. Share: Send the link, embed the page on another site, or let people find it on the Wall. 4. Interact: Visitors view, use and like it. Turn on submissions to collect their text, image or code responses. ## Step-by-step guides - [How zlo works](https://www.zloapp.com/help-center/overview): Follow an idea from capture to published work.

The first 50 pages. The eye on the file switches it to a download chip. - Word, Excel, PowerPoint (.doc .docx .xls .xlsx .ppt .pptx): Microsoft's online viewer, in the page. The eye on the file switches it to a download chip. - Images (.png .jpg .jpeg .webp .gif .svg): In the page and as tiles under Images. Photos over 400 KB are resized to at most 2000 px and compressed. GIF and SVG stay as they are. - Videos (.mp4 .mov .m4v .webm): Played in the page. Converted in your browser to an MP4 of at most 1080p when needed. A clip too long to fit is refused; embed it from YouTube or Vimeo instead. - 3D models (.obj .glb .gltf .stl): A 3D viewer you can turn around. - A whole website (.html .htm .zip): Opens as the page itself. A ZIP needs index.html at the top, and holds one page. Or you can keep a ZIP as a file to download. - Text (.txt .md .json): Opens in the editor as the item's content. - Everything else (.odt .rtf .odp .key .ods .numbers .pages .psd .ai .fig .sketch .xd .epub .3mf .mtl .fbx .step .stp .iges .igs .blend): A chip people tap to download. ### Challenge and assignment entries Entries take fewer formats than Code Studio. Submitting needs a signed-in account. - Type or paste (Text, Markdown or HTML code): Press Run to preview it before you submit. - Upload a page (.html .htm .txt .md .zip): One file. A ZIP runs as a page, with index.html at the top. - Add images (.png .jpg .jpeg .webp .gif .svg): Several at once, or paste from the clipboard. Place them with [img01], [img02]. - Write on sheet (Pen on the task's PDF): Only when the task has a PDF among its files. Each written page is saved as a picture. - PDF, Office, video and 3D files can't be attached to an entry directly. Video, audio and 3D can travel inside a ZIP page. ### Size limits - Any uploaded file (PDF, Office, 3D, video, download): 25 MB - An image: 8 MB - A text or HTML file dropped into Code Studio: 8 MB - A single HTML file through Import: 2 MB - A ZIP page, after its pictures are compressed: 25 MB - A ZIP file before it is opened: 300 MB ## More - [Start](https://www.zloapp.com/start): The same as this file, as a page. - [The Wall](https://www.zloapp.com/wall): What people are making right now. - [Chrome extension](https://www.zloapp.com/extension): Bring pictures and links from any website into your page. - [Contact, report a post, copyright](https://www.zloapp.com/help) - [Terms of Service](https://www.zloapp.com/terms) · [Privacy Policy](https://www.zloapp.com/privacy) · [Community Guidelines](https://www.zloapp.com/guidelines) ## For AI tools asked to make a page - [Full page-making rules](https://www.zloapp.com/llms-full.txt): The format, markers and rules for a Zlo page.
