Whiteboard

Language note: Media, interface labels, and examples remain in their original language. Portuguese labels are kept as displayed, with English explanations where useful.

Overview

Our whiteboard was built to be the center of your virtual classroom. It combines real-time creation tools with features designed specifically for language teachers, including:

Essential Creation Tools: A complete set of elements for drawing, writing, and organizing ideas.
Two PDF Tools: One for quick viewing and another for embedding and editing PDFs directly on the canvas.
AI Assistant: Tools for instantly generating audio and images from text.
Synchronized Audio: An audio player that keeps all students on the same page during listening activities.

Essential Creation Tools

Built on an intuitive foundation, our whiteboard provides all the elements you need to create and collaborate without limits.

✍️ Caneta (Pen): Draw freely, write by hand, underline text, and take quick notes.
📝 Notas Adesivas (Sticky Notes): Perfect for brainstorming sessions, collaborative notes, or highlighting vocabulary.
🅰️ Texto (Text): Add formattable text boxes anywhere on the canvas to create instructions, questions, or examples.
🔷 Formas Geométricas (Shapes): Use rectangles, circles, and lines to create diagrams, flowcharts, or activity areas.
🔗 Setas e Conectores (Arrows and Connectors): Connect ideas, match images to text, and create clear, organized mind maps.
🖼️ Upload de Imagens (Image Upload): Bring any image onto the whiteboard as a starting point for discussions and exercises.
👆 Ferramenta de Seleção (Selection Tool): Easily move, resize, group, and organize all the elements on your canvas.

Working with PDFs: Viewing vs. Integrated Editing

We understand that PDFs are essential teaching materials. That is why we offer two distinct tools so you can work with them in the most convenient way.

1. The “Visualizador de PDF” (PDF Viewer) Tool

When you only need to present a document, article, or book page for reading, use the PDF Viewer.

How to use it:

In the toolbar, click to expand the elements menu (where shapes, arrows, and other elements are located).
Select the PDF icon.
This adds a “Visualizador de PDF” object to your canvas. Click it to upload your file.

This tool is ideal for navigating page by page, zooming in, and reading content together, without permanently embedding the file in your workspace.

2. Drag-and-Drop Import for Editing

To turn your static materials into interactive activities, use direct import.

How to use it: Simply drag a PDF file from your computer and drop it anywhere on the whiteboard.

When you do this, Slingui converts each page of your document into a native canvas element, just like an image. This lets you:

Annotate directly on the material: Circle answers, fill in blanks, and write notes on your PDF pages.
Use all the other tools: Add sticky notes, text boxes, and shapes over your material to create rich activities.
Encourage collaboration: Ask students to solve textbook exercises together, in real time, directly on the whiteboard.

Artificial Intelligence: Your Creative Assistant

Bring your ideas to life and create teaching resources instantly with our built-in AI tools. The process is simple: add the AI element you want to your whiteboard, write what you want to create (a “prompt”), and let AI generate the resource for you in seconds.

1. AI Audio Generator (Text to Speech)

Need audio for a word or phrase with clear pronunciation? With this tool, simply add the AI audio element, enter the text, and AI will create an audio file for you.

Ideal for:

Demonstrating vocabulary pronunciation.
Creating short listening exercises on the spot.
Generating lines for dialogues without recording your own voice.

The generated audio can be played using our synchronized player, ensuring that all students hear it at the same time.

2. AI Image Generator

Turn descriptions into images! A picture is worth a thousand words, especially in language teaching. Add the AI image element, describe the scene or object you have in mind (for example, “um gato feliz andando de bicicleta em Paris”), and AI will create a unique image for you.

Use it to:

Create fun visual icebreakers.
Generate images for description exercises (“Descreva o que você vê”).
Illustrate vocabulary in creative, memorable ways.
Inspire storytelling activities using an unexpected image.

Synchronized Audio for Group Activities

Listening activities have never been easier to coordinate. Our built-in audio player provides real-time synchronization.

When the teacher plays, pauses, or skips ahead in the audio, the action is instantly replicated on every student’s screen. This ensures that the whole class hears the same section of the audio at the same time, eliminating confusion.

Important: User Interaction

For security reasons in modern browsers (autoplay restrictions), audio cannot play automatically until the user has interacted with the page.

Quick Tip: At the start of the lesson or audio activity, ask your students to click once anywhere on the whiteboard. This simple action ensures that the synchronized player works properly for everyone.
