Brand themes: one workspace, multiple brands

Brand themes: one workspace, multiple brands

One Workspace. Multiple Brands.​

Create and manage multiple brand themes with Themes in Company Settings, so each demo can have the look and feel it needs.

Whether you're showcasing different products, supporting multiple brands, or letting partners deliver demos under their own branding, every audience gets a consistent, on-brand experience. You do it all from one workspace: no second account, and no restyling demos one by one.

A theme is a named set of brand values: colors, fonts, buttons, avatar, dim intensity and interactions. Your workspace has one workspace default theme and as many others as you need.

When to use themes​

Use a separate theme whenever a demo should look like it comes from someone other than your core brand:

  • Multiple products or product lines. Each product keeps its own colors and fonts while sharing one library, one team and one set of analytics.
  • Multiple brands under one company. Sub-brands, acquired companies and regional brands each get their own look without separate workspaces.
  • Partners and resellers. Give a partner a co-branded or white-labeled theme so they can deliver your demos under their own branding.
  • Campaigns and events. A launch or conference can have its own look for a few weeks, then you switch back.

If all your demos should look the same, you only need the workspace default. Change it once and every template and demo that follows it updates.

Set it up in 3 steps​

1. Create a theme​

  1. Go to Company Settings → Brand style.
  2. In the Themes list, start the theme one of three ways:
    • New theme — begin from the workspace default and set every value yourself.
    • Create with AI — have Walnut read the brand off a website or a deck, then open a draft you review before saving (see Create a theme with AI below).
    • Duplicate — open an existing theme's menu and choose Duplicate to start from its look. Useful for sub-brands that only differ in a few values.
  3. Give the theme a name your team will recognize, for example "Partner — Acme co-brand".
  4. Set its colors, fonts, buttons, avatar, dim and interactions, then click Save.

Create a theme with AI​

In the Themes list, click Create with AI to open the Create theme with AI dialog. Pick a source:

  • Website — paste a public web address, like acme.com. Walnut opens the page, reads colors from buttons, text and links, finds the main font and site icon, and checks text is readable on the colors it picked.
  • Presentation — upload a .pptx or .pdf deck up to 50 MB. Walnut reads the first 5 slides for background, accent and text colors and the main font, and checks the same readability.

A progress checklist runs as Walnut works (opening the source, reading colors, finding the font, checking contrast); runs usually finish in under a minute. When it’s done, Walnut opens the theme as a draft, pre-filled with everything it found and prefilled name set to the site host or file name. Rename it, tweak any value and click Create theme to save it to your Themes list. A theme that was started this way shows a Made with AI badge on its row.

If Walnut can’t reach the site or can’t read the file, the dialog says so and offers to try another link or upload a deck instead. Create with AI uses AI credits; if your workspace is out of credits the button is disabled and the dialog links to View AI credit usage.

To make a theme the look everything uses unless told otherwise, choose Make workspace default from its menu.

2. Point templates and demos at it​

  • Template: in the editor's sidebar settings, open Brand style and pick the theme. Pick Custom if this template needs its own look.
  • New demo: the Branding field in the Create demo wizard is pre-filled with the template's theme. Pick another theme to change the new demo's look before it is created.
  • Existing demo: pick a theme in Demo preferences or in the Share modal. New share links show it at once. Links you shared earlier keep the look they were published with until you republish.
  • Live-theme share links: in the Share modal's Branding tab, pick a theme and copy a share link to generate a link that stays current. A live-theme link looks at the demo's theme every time it opens, so changing the demo's theme in Demo preferences updates the link for every viewer without a republish. Links copied from any other tab stay pinned to the theme they were published with, as before.

Playlists and Deal Rooms can apply a theme from their Styling panel too, so the hub around your demos matches them.

3. Personalize the content with presets​

A theme changes how a demo looks. A demo preset changes what it says: customer name, industry, currency, logo and sample data. Use both and one master template covers every audience:

  • Theme: the brand on the demo (yours, a sub-brand's, or a partner's).
  • Preset: the story for the account you're meeting ("FinServ — enterprise", "Retail — mid-market").

For example, a partner's SE opens your demo with the partner's co-brand theme, picks the "Healthcare" preset on the Pre-flight screen, and presents a demo that looks like the partner's and speaks to a healthcare buyer. You built it once.

Good to know​

  • Nothing has to be set everywhere. Brand values resolve field by field: a template's own overrides win, then the demo's theme, then the template's theme, then the workspace default.
  • Deleting a theme doesn't break anything. Before you confirm, Walnut lists the templates and demos that use it and what each will fall back to. Published links keep what they were published with.
  • Not every setting is part of a theme. Workspace-wide switches, such as smooth screen transitions and the X and Back buttons, stay set once for the whole workspace.

For every theme field and action, see Company Settings → Brand style.

Create a theme with AI​

If you have a public website or a brand deck, Walnut can draft an on-brand theme for you in about a minute. You review it in the theme editor and save when it's right — nothing is applied to your demos until you do.

Start a draft​

  1. Go to Company Settings → Brand style. In the Themes card, click Create with AI.
  2. In the Create theme with AI dialog, pick a source:
    • Website — paste a link (for example acme.com). A company home page works best. Walnut adds https:// if you leave it off.
    • Presentation — upload a .pptx or .pdf of up to 50 MB. Walnut reads the look of the first 5 slides.
  3. Click Generate. The dialog shows the steps as they run (reading colors from buttons, text and links; finding the main font and site icon; checking text is readable) and usually finishes in under a minute. You can Cancel at any time; credits already used stay used.

One generation runs per workspace at a time. Theme generation uses AI credits — the dialog has a View usage link to the AI Control Center.

Review the draft​

When the run finishes, the theme editor opens with the draft loaded under a name you can edit. Every field the generation filled is marked with an AI badge, and an Edited badge appears next to any AI value you change.

At the top of the editor, a Made with AI from [source] note reminds you to check the AI-marked fields, lists any fields Walnut didn't have enough brand information for (those keep your current Brand style values) and, when Walnut couldn't load the brand's own font, names the closest built-in it used instead. If the font came from a website, the note includes a shortcut to upload the original font file.

Nothing is applied until you click Save. In the Themes list, saved AI themes carry a Made with AI badge, and duplicates of them keep it.

If a run can't finish​

Some brand pages can't be read automatically — a site that needs a login, shows an error page, blocks automated visits, or that we couldn't reach. The dialog says which it was and offers to try another link or upload a deck instead. For a deck that can't be read (damaged, password-protected, or over 50 MB), upload a smaller or different file. If Walnut is out of AI credits, the dialog says so and links to AI credit usage.

FAQ​

How many themes can I create? As many as you need. One of them is always the workspace default.

Do I need a separate workspace for a partner or sub-brand? No. Create a theme for them and point their templates or demos at it. Content, users and analytics stay in one workspace.

Can a preset switch the theme? No. Presets fill in variable values only. Pick the theme on the template or demo, and pick the preset when you present.

I changed a demo's theme. Why does an old link still show the previous look? Links shared before the change keep the look the demo was published with. Share a new link, or republish the demo to update the old ones.
