Ideas, made presentable

About Tertin

Tertin is an AI presentation maker by NerfedLab.

Prepare a client pitch, explain a product decision or build a training session. Start with an AI draft, then shape the story and design with direct editing on the canvas.

Your presentation, down to the details

From a first draft to work you can present

A useful deck needs the right message and the right emphasis. Refine the words, adjust the design and prepare your delivery in one editor.

Control the visual details

Adjust typography, layout, colors and images. Use layers to select the element you want to refine without losing sight of the whole slide.

Edit HTML slides directly

Retype text on the slide or use the selected element controls. Open the slide's HTML source when you want to work with its code.

Refine the story in conversation

Give the AI context, ask for changes and review any source references included in its responses. Check the facts before using them in your presentation.

Reuse your own visual style

Save a personal design system for future decks. These saved styles and slide masters live in your browser, under your account.

Explain ideas with data

Create slides with charts and tables alongside text, images and shapes. Choose the format that helps your audience understand the point.

Prepare your delivery

Add speaker notes to individual slides and read them in the presenter view while you talk through the deck.

Available editing controls depend on the slide format and selected element.
