From brief to boardroom slide. On your template, fully editable.
Thea is an AI agent that designs and builds native PowerPoint slides on your organisation's own template. Not pictures of slides: real shapes, real text, real charts you can edit like anything else in your deck.
Great thinking, stuck behind hours of formatting
Consultants and corporate teams lose evenings aligning boxes, fixing fonts and rebuilding slides on a client's template. Many AI tools produce pictures of slides, or slides in their own style, so the work ends up being redone by hand anyway.
Thea was built to remove that step: you bring the argument, and Thea builds the slide.
A finished slide, not a picture of one
This is the kind of slide Thea builds from a two-line brief. Everything on it is native PowerPoint, on the client's own template.
- 1Editable textEvery title, label and takeaway is a real text box you can rewrite.
- 2A real chartChange the numbers in PowerPoint and the chart updates.
- 3Your templateColours, fonts, footer and page numbers come from your own template.
Four ways to work with Thea
Create
Describe a slide and Thea designs and builds it. Name several slides in one brief ("Slide 1, Slide 2, Slide 3…") and get them back as one deck, in the order you asked for, up to 12 at a time.
Enhance
Upload an existing deck, choose the slides that need work, and Thea redesigns them in place. Your titles and template are kept, and the rest of the deck is untouched.
Build from your design
Have a sketch or a slide you like the look of? Upload the image and Thea rebuilds it as a native, editable slide on your template.
Chat
Work out the argument before a slide exists: sharpen a storyline, test a message, ask what a term means. Chat never builds anything, so it's a safe place to think out loud.
Slides you'd put in front of a board
Thea checks its own work. Before a slide reaches you, it's reviewed for alignment and consistency, the details a senior reviewer notices first.
Native & editable
Every shape, text box and chart is real PowerPoint. Change anything.
Your template
Colours, fonts and layouts come from your own template's theme.
Consistent icons
One clean line-icon style across every slide, sized and centred properly.
Aligned before you see it
Every build finishes with an alignment check: edges, gaps, icons and sizes.
On the web, or on your desktop
One design engine, shared by both products, so they always build the same way.
