Summarize with AI
An AI copilot that wants a custom coded website fits best with Studio Maydit, because one team can code a working copy of your copilot inside its host app on the homepage, then keep designing the copilot after launch. Of the other nine, basement.studio and Phantom lead: both name custom code as their main platform and have published AI client work, and basement.studio counts Cursor, an AI code editor, as a client. In order of fit, the ten studios worth reviewing are Studio Maydit, basement.studio, Phantom, Feels Like, Engine Digital, Fantasy, Feely Studio, Ramotion, Instrument, and Pixelmatters. Only four competitors, basement.studio, Phantom, Feels Like, and Engine Digital, build in custom code first. Fantasy, Feely Studio, Ramotion, Instrument, and Pixelmatters work across mixed tools, so ask each one whether your site would be hand coded. Instrument and Pixelmatters are the weakest fit.
Take one product. It is a copilot that writes spreadsheet formulas for finance teams, inside Excel and Google Sheets. An analyst types EMEA revenue since July into a cell. The copilot answers in grey with a SUMIFS formula, three ranges and a date. The analyst presses Tab, and the number is right.
On the company's homepage, that moment is a 38 second video recorded on a large monitor. On a phone the formula is a grey blur, so the finance lead who opened the link from Slack cannot read the one thing that proves the product works. Search engines and AI assistants cannot read it either.
A coded site can draw a small, real grid in the browser instead. The visitor picks a question, watches the formula arrive in grey, presses Tab or taps, and sees the result and the formula as plain text on any screen.
The studios below are ranked on who can build that, and who leaves your team able to change it when the copilot changes.
How the ten were scored
- Code as the main craft. A copilot site needs a demo that behaves like Excel, an IDE, or an inbox. Does the studio write code first, or build mostly in Webflow, Framer, or a mix?
- Proof with AI products that live inside other software. Named AI clients count. A client like Cursor, whose product works where people already write code, counts most.
- A public minimum. We noted only whether a starting price is posted. No studio's figure appears here.
- Who builds the demo. Team size hints at whether the engineer coding the fake host app joins your calls in week one, or arrives after the design is locked.
- The studio's own site, on a phone. Load it on mobile data. Does the text appear before the effects? Can you use anything that moves, or is it decoration?
Treat that fifth check as a dress rehearsal. No client asked for changes on a studio's own site, so it shows the best the studio does unwatched. If its own interactive pages stutter on a phone, your demo will too.
Each table row repeats what a studio says on its own website or a public directory profile, read in October 2026. Private facts show as Not published. Nobody paid for a place.
What goes wrong when a copilot team commissions a coded site
The demo shows last quarter's copilot. The studio hand builds a lovely copy of the host app and your suggestion box inside it. Three months later your product team moves the accept button and adds a confidence label. The site still shows the old version, and a trial user notices the gap on day one. Ask the studio to build the demo from your own design tokens, or from a recorded session file your engineers can export again after each release.
The demo is so heavy the page is blank. A simulated spreadsheet or editor can ship a large script bundle. On a mid range phone the hero sits empty for three seconds, and if the demo is drawn on a canvas, none of its text reaches search engines. Ask for a weight budget in writing, real HTML text inside the demo, and a test on a cheap Android phone before launch.
The install button sends everyone to one store. Your copilot ships through two or three marketplaces, each with its own consent screen. The site has a single Get started button that opens the Chrome Web Store, even for a visitor in Excel on a Mac. Then the store asks for access to every spreadsheet, and the visitor leaves. Ask for one page per host, built from a single list, that names each permission in plain words before the store screen does.
1. Studio Maydit: A Top-Rated Design Agency for AI Founders
A copilot team needs two things at once: a site that shows the product working inside its host app, and someone to keep improving the copilot. Studio Maydit is a web and product design studio that does both for AI founders in the US, UK, and Europe. It builds in Framer, Webflow, and custom code, and a copilot usually wants code. Once the site is live, the same people move on to product design for the suggestion box, the accept and undo states, and the first run.
Proof comes from a tool developers use every day. Dualite brought the studio in for its site and its product, and design work supporting a repositioned ICP helped it pass 100,000+ users in seven months. Read the Dualite case study to see both halves. Wave, PixelFlow, and Mi-VAD hired the studio recently too, as did 15 other AI and SaaS teams.
There are two ways to buy. A fixed scope takes three to four weeks and fits a copilot with a date, such as a new marketplace listing going live, and it finishes with a diagnosis of what is leaking in the product, for example where trial users stop before they accept their first suggestion. A copilot that adds a new host app or feature most months can take a monthly retainer instead, covering new pages, campaigns, and product design, with no long lock-in.

2. basement.studio
basement.studio has coded sites from Mar del Plata, Argentina and Los Angeles, USA since 2018, for clients including Vercel, Cursor, ElevenLabs, Harvey AI, and Scale AI. Cursor is an AI code editor, so this team has already shown an AI helper at work inside a busy tool. It posts a minimum.
With 11 to 50 people and a client list this wanted, start dates can be far out. Ask early.

3. Phantom
Phantom codes from London, UK and Auckland, NZ, with 51 to 200 people, and has published AI client work. Its clients include Zendesk and SAP, software whole teams work inside all day, the kind of host many copilots plug into.
Phantom does not publish a minimum, and its named clients are large. A ten person copilot team should ask how small a project it takes.

4. Feels Like
Feels Like is a young Los Angeles studio that builds in custom code, with published AI client work for Suno AI alongside Google, Nike, and LVMH. A copilot for writers or designers gets a coding team used to work that must feel lively, not just correct.
It publishes neither its team size nor a minimum, so its record is short. Ask to see a real product screen it rebuilt in code.

5. Engine Digital
Engine Digital has worked from Vancouver and New York since 2002, and custom code is its main platform. Its clients include Adidas, Autodesk, Goldman Sachs, and HP. Autodesk makes design software that engineers keep open all day, so the team knows a host where a copilot would have to earn its place.
Its AI proof is partial, and it publishes neither its team size nor a minimum. A small copilot team should ask who would actually do the work.

6. Fantasy
Fantasy has worked from San Francisco and New York, USA since 1999, with published AI client work. A copilot company still choosing which host apps to back gets a long-running team to think that through before any code.
Fantasy works in mixed tools, not custom code first, and publishes no named clients, no team size, and no minimum. That leaves very little to check before a call.

7. Feely Studio
Feely Studio is a team of one to ten people spread across Europe, with published AI client work for Noxus, Mutiny, Luasai, and Basic Capital. It posts a minimum, which helps a seed copilot team plan.
Feely works in mixed tools, not custom code first, so a coded in-host demo may need an outside developer. A team this small has limited room.

8. Ramotion
Ramotion is a San Francisco, USA studio of 11 to 50 people, founded in 2009, and it posts a minimum. Its clients include Mozilla, Okta, Netflix, Adobe, and Xero. Mozilla makes a browser and Adobe makes tools people work in for hours, so the team knows products that host other people's add-ons.
Its AI proof is partial, with no AI case study, and it works in mixed tools rather than custom code first. It is a premium studio, which strains a seed budget.

9. Instrument
Instrument has worked from Portland, USA since 2005, for Nike, Microsoft, Electronic Arts, and Google. Microsoft and Google both own the office suites many copilots plug into, so the team has worked on the host side of that relationship.
Its AI proof is partial, and it publishes neither its team size nor a minimum. It works in mixed tools, not custom code first, and its usual clients have budgets far above a seed round.

10. Pixelmatters
Pixelmatters works from Porto, Portugal, with 51 to 200 people, founded in 2013, and it posts a minimum. Its clients include Rubrik, Quantic, and UJET. UJET sells software for support teams, a common home for copilots that draft replies, and the team sits in a European time zone.
It ranks last for this brief because it works in mixed tools, not custom code first, and its AI proof is partial. Ask early whether your demo would be real code or a video in a site builder.

How to choose between them
Start from what your site gets wrong about your copilot today.
Your demo is a video nobody can read on a phone. You need a coded, in-host demo with real text. Studio Maydit, basement.studio, or Phantom.
You support three host apps and the site only talks about one. You need a page per host, built from one list, with the right install link on each. Studio Maydit, Phantom, or Engine Digital.
Your copilot is for creative work and the site looks like every developer tool. You need brand feel as much as code. Feels Like, or Fantasy if the strategy is not settled yet.
You are pre-seed with one host and five pages. Feely Studio for a small European team, or Ramotion if you have the budget and an engineer of your own.
One test before you sign. Ask the studio to show you, on its own site, a piece of interface rebuilt in code that you can click on a phone. If it can only show you videos, your demo will be a video too.
