A workspace that looks and works like your business, signed off on your phone. ## At a glance - **You share:** Your brief: your brand, the features your team uses most and how it should feel - **It plans:** The feature list, the navigation idea and the look and feel, written into the theme's plan - **It tests:** In a real browser on desktop and phone sizes, with screenshots from every round - **Feature checklist:** Shows everything the standard workspace does still works in your theme - **Your way back:** A one-click link to the standard workspace, always there - **What it never changes:** The platform underneath, your data or the built-in themes ## What the Theme Builder does - **Turns your brief into a plan:** It walks you through the menu of workspace features and agrees the feature list, the navigation idea and the look and feel, all written into the theme's plan. - **Builds from a proven starting point:** Each theme starts from a tested blueprint rather than a blank page, and the riskiest piece is proven first. - **Tests like a real user:** It drills the theme in a real browser on desktop and phone sizes: sending messages, stopping tasks, uploads and deliberately breaking things to check the rescue link works. - **Tracks every feature:** A checklist shows that everything the standard workspace does still works in your theme, updated after every test round. - **Adds the extras your brief needs:** When your theme needs richer data, such as detailed project profiles, it designs a theme pack with you to hold it. - **Polishes round by round:** Your feedback becomes a list of concrete fixes. Each round is tested again before you see it. ## How the Theme Builder differs from a one-size-fits-all workspace screen A standard screen treats every business the same and puts every feature in front of every person. The Theme Builder designs a look and navigation around your brand and the features your team uses most, starting from a tested blueprint rather than a blank page. It tests on desktop and phone, turns each piece of your feedback into a concrete fix and keeps a one-click link back to the standard workspace. ## How it works 1. **Share your brief** (When you share your brief): Tell it how you want your workspace to look and work. It walks you through the feature menu and agrees the plan with you. 2. **Build the foundation** (After the plan is agreed): It starts from a blueprint theme, proves the riskiest piece first, then builds the layout for desktop and mobile. 3. **Test on real screens** (Every test round): Every round is drilled in a real browser on desktop and phone sizes, with screenshots and an updated feature checklist. 4. **Polish from your feedback** (After you try it): You try it and say what you would change. Every sentence becomes a concrete fix in the next round. 5. **Sign off on your phone** (you approve) (When it feels right on your phone): When it feels right on a real phone, you sign off. Until then, it keeps polishing. ## When to use it - **Your workspace should look like your brand:** Get a theme with your look and feel, so your team feels at home every time they open Ai1. - **Your team only uses a few features:** Put those front and centre with navigation built around how your people actually work. - **You run lots of client projects:** A theme pack can add rich project profiles to your workspace so the right details are always to hand. - **Your team works mostly on phones:** The theme is built and tested for phone screens from the start, not squeezed in at the end. - **You want to try something bold:** Experiment freely. A one-click link back to the standard workspace is always there. ## What you get - A complete branded theme for your Ai1 workspace, on desktop and phone - A theme plan with the agreed features, navigation and look and feel - A feature checklist showing everything still works in your theme - Screenshots from every test round on desktop and phone sizes - Theme packs for any extra data your brief needs, designed with you - A short record of what was learned, for future rounds ## Example: workspace theme plan and polish round report Example with a fictional company. Names, people and figures are invented to show the agent's output. Any resemblance to a real company or person is unintended. What it was asked: Make our workspace look and feel like Zephrenna, put weddings first, and make it easy to use on my phone between deliveries. This is an illustrative example of the plan and round report Theme Builder is being built to produce: agreed feature list, feedback fixes, drill results and the sign-off checklist. It was written by hand from the agent's design for an invented florist with invented feedback and results. No real workspace, brand, systems or people were involved, and nothing was switched on or changed. Run date: 14 October 2026. ### What it found - Round 3 turned 8 pieces of the owner's feedback into concrete fixes: 7 are done and drilled on desktop and phone, and long file names on phones move to round 4. - The parity checklist now passes 56 of 56 items on desktop and 52 of 56 on a phone; the 4 phone gaps are small layout and tap-size fixes. - The link back to the standard interface was tested 3 times by breaking the theme on purpose, and it worked every time. ## Guardrails - Your Ai1 team will tell you when the Theme Builder is ready for your account. - It changes how your workspace looks and works, never the platform underneath, your data or the built-in themes. - Every theme keeps a one-click link back to the standard workspace, and that link is never removed. - If something in the platform seems broken or missing, it stops and tells you instead of working around it. - Deleting any theme pack data is your decision alone, confirmed in a standard dialog. ## Frequently asked questions ### What does branded workspace design involve? Agreeing which features your team needs, how people move between them and how it should all look and feel. The Theme Builder writes that into a theme plan, builds it from a tested blueprint and checks it on desktop and phone before you see it. ### Can a workspace carry my own branding without breaking anything? Yes. The Theme Builder changes how your Ai1 workspace looks and works, never the platform underneath, your data or the built-in themes. A checklist shows every standard feature still works, and a one-click link back to the standard workspace is always there. ### How do you design a custom interface that works well on phones? Build and test for phone sizes from the start instead of squeezing a desktop layout in at the end. The Theme Builder drills each theme in a real browser on desktop and phone sizes, and you sign off only when it feels right on a real phone. ### What is a custom workspace theme from Theme Builder? It is a complete alternative look for your Ai1 workspace, designed around your brand and the features your team uses. Inside each conversation things work just as before, while the entry and navigation can be built your way. ### Will a new theme break anything? It is tested in a real browser on desktop and phone sizes, with a checklist proving every standard feature still works. The platform underneath and your data are never changed. ### What if we do not like the result? Every theme keeps a one-click link back to the standard workspace. And you can keep giving feedback, since each round turns your comments into concrete fixes. ### How long does it keep polishing? Until you sign off. Rounds continue, each one tested before you see it, until the theme feels right on a real phone. ### Can the theme hold information the standard workspace does not? Yes, through a theme pack. If your brief needs something like detailed project profiles, it designs the pack with you. ### Is the Theme Builder available now? Not yet. Your Ai1 team will tell you when the Theme Builder is ready for your account.
