The AI workspace for one-person companies

BUILD A
MILLION-DOLLAR
COMPANY. ALONE.

Kaiday is the AI workspace where one freelancer, founder, or side-hustler can run what used to take a team. Describe what you want, Kai builds it — apps for your clients, automations, emails, meetings, code, decks. No developer. No hires. No enterprise budget.

Start today — free 30-min setup

No credit card. No developer. No template-builder feeling.

Talking to Kai
›

Real prompts. Each one becomes a working artifact in your workspace.

The asymmetry

THEIR DATA IS IN 47 TOOLS.
YOURS IS IN ONE.

A Fortune 500 has its customers in Salesforce, billing in Zuora, docs in Confluence, code in GitHub, email in Outlook, chat in Slack and Teams. Every cross-system action is a 14-month integration project. AI is only as useful as the data it can see — and theirs is in cages. You skipped that era. That's the moat.

47 tools that don't talk to each other.

Your stack
Kaiday
+ Stripe + your DNS

One workspace. Connected by default.

While theyspend three weeks getting a churn report through five approvals,
Youask Kai at 4pm and post the chart in #revenue by 5.
While theyhave the product team write a JIRA epic for a dark-mode toggle,
Youship it Saturday morning, before lunch.
While theyschedule a meeting to discuss responding to a viral mention,
Youhave already replied, posted the follow-up, and added the topic to next week's calendar.
While theybuild a 90-day onboarding via 4 SaaS tools and 7 teams,
Youbuild one client portal that walks every new client through the whole thing.

Pace beats scale on every move that doesn't require capital.

The data moat

Three layers. Every layer makes you harder to copy.

Workspace Data

Every email, document, meeting note, and CRM record lives in one connected graph — not 47 silos.

Workflow Traces

Every automation, every decision path, every client interaction is captured as a traceable workflow.

MiniApp Traces

Every MiniApp generates usage data, user behavior, and operational patterns — compounding intelligence.

The longer you use Kaiday, the smarter it gets. That's the moat.

Open-source strategy

OPEN WHERE IT ACCELERATES.
PROPRIETARY WHERE IT PROTECTS.

Kaiday open-sources the layers that benefit from community — the MiniApp SDK, the Runtime Sandbox, and the Template Marketplace Starter Kit. The core workspace OS and AI orchestration engine remain proprietary.

Open source

  • MiniApp SDK — build and extend MiniApps locally
  • Runtime Sandbox — the secure execution environment for MiniApps
  • Template Marketplace Starter Kit — publish and share MiniApp templates

Proprietary

  • Core workspace OS — the unified email, calendar, CRM, and documents engine
  • AI orchestration — Kai's reasoning, memory, and multi-surface agent loop

Developers extend the platform. The platform compounds for everyone.

What it is

ONE WORKSPACE. ONE ASSISTANT.
EVERYTHING YOU NEED.

Kaiday replaces your tool stack. Email, calendar, video, messaging, documents, presentations, social, apps, automations — all native, all in one place, all driven by talking to Kai.

The promise

FROM ZERO TO RUNNING
IN 30 MINUTES.

A real timeline. By minute 30 you have a verified domain, working email, a public client-facing app on your URL, an automation handling leads, and a week of social queued.

0–5 min

Sign up. Tell Kai about your business.

One conversation. Kai stores everything in memory and uses it everywhere from here on.

6–15 min

Verify your domain. Mint mailboxes.

Paste the DNS records. While they propagate, you keep moving.

16–22 min

Build your first App.

"Build a wedding-inquiry form at book.menoru.com." Kai writes it, deploys it, hosts it under your domain.

23–27 min

Wire the automation.

"When the form is submitted, create a contact, send my pricing PDF, book a discovery call." Kai turns the sentence into a real workflow.

28–30 min

Queue a week of content.

"Draft 5 LinkedIn posts and 5 Instagram captions, in my voice, schedule across the week." Done.

Start your 30 minutes

The unfair advantage

YOUR CLIENTS GET
CUSTOM SOFTWARE.
YOU JUST TALK.

Apps are real, hosted apps on your domain — built by Kai from a sentence. Client portals, intake forms, booking flows, calculators, galleries, dashboards. The same software a billion-dollar company has. Built by you in an afternoon.

You say to Kai

"Build a private gallery for the Nguyen wedding. They pick favorites, sign the model release, pay the balance, get the download."

Live at gallery.menoru.com/nguyen in minutes

Hosted on your domain. Wired to your clients, your invoices, your storage. Iterate by talking: "make the favorites grid 4 columns" or "add a question for the album cover preference."

START YOUR SIDE BUSINESS TODAY.

Photographers

Inquiry funnel, private galleries, shot-list intake, referral tracker.

Coaches

Intake quiz, per-client portal, weekly check-ins, paid resource library.

Lawyers & accountants

Matter intake, document portal, flat-fee storefront, status dashboard.

Consultants

ROI calculator, audit quiz, proposal generator, engagement dashboard.

Trainers & dietitians

Assessment, personalized program viewer, progress tracker, form-check portal.

Real-estate agents

Affordability calculator, buyer quiz, neighborhood guide, valuation request.

Not on this list? Kaiday works the same way for every solo business — you describe what you do, Kai builds it.

The structural moat

MINIAPPS: FULL-STACK APPS
FROM PLAIN LANGUAGE.
WIRED TO YOUR LIVE DATA.

Kaiday generates operational web apps — not prototypes, not UI mockups. Describe what you need, and Kai builds, deploys, and hosts it on your domain. Client portals, booking flows, dashboards, calculators — full-stack software wired into your live business data.

Plain language to production

Describe an app in a sentence. Kai builds it, deploys it, hosts it under your domain. No code, no config, no DevOps.

Connected to live data

Every MiniApp reads and writes your real business data — clients, invoices, calendar, messages. Not a sandbox. Not a demo.

Iterated by conversation

"Add a payment step." "Change the grid to 4 columns." Kai edits and redeploys instantly. Your app evolves at the speed of chat.

Why this is a moat

Cursor, v0, Lovable, and Bolt.new generate UI code. Kaiday generates operational software that knows your business.

AI coding tools produce static frontends from prompts. They don't know your client list, your invoice schema, your email history. Kaiday MiniApps are full-stack, data-connected, and business-aware — a structural advantage that compounds with every app you build.

Built-in distribution

EVERY MINIAPP IS A
DISTRIBUTION CHANNEL.

When you build a client portal, a booking page, or a gallery for your customers, it lives on your domain — and every visitor sees the Kaiday brand. Your clients' experience becomes our growth loop.

Powered by Kaiday

Every branded MiniApp portal your clients use carries a subtle 'Powered by Kaiday' badge. Each one is a live demo, a referral, and an acquisition channel — all while you look like the enterprise you are.

What you can actually do now

SOLO, WITH THE LEVERAGE
OF FIFTY.

The specific capabilities you didn't have access to a year ago. Each one is something a small team used to be required for.

Speed

Idea to live App in an afternoon. Customer complaint to merged PR in 4 minutes.

Polish

One person looks like a company. Your domain, your apps, your branded recordings. No 'powered by' badges.

Memory

Never forget a client conversation, a decision, or a price you quoted. Kai remembers across every surface.

Multi-arm strategy

Run two or three companies at once — each with its own brand, domain, Apps, and Kai memory.

Pattern recognition

See what a 20-person team would see. Patterns Kai surfaces because it sees everything you've done.

The night shift

While you sleep, Kai works. Inbound triaged, social monitored, recurring reports run. You wake up to a triaged universe.

Bespoke per-client

Each client gets an experience tuned to them — their data, their name, their branded portal. The enterprise touch your competition can't afford.

Compounding context

Day 1 Kai is a tool. Day 180 it knows your voice, pricing, decisions, voice. Every conversation makes the next one cheaper.

The math

STOP PAYING FOR
TWELVE TOOLS.

The real value isn't any one feature. It's that your email knows about the invoice, which knows about the goal, which knows about the meeting, which knows about the client.

Google Workspace
Slack
Zoom + Otter
Calendly
Typeform
Squarespace
Mailchimp
Notion
Zapier
Honeybook
Mapbox
Vercel

What you keep paying for

Stripe. Your DNS. That's it.

Why this compounds

ON DAY 180, IT'S A
DIFFERENT PRODUCT.

Every conversation refines what Kai knows. Every App is one more thing your competitors don't have. Every automation is one more thing you don't touch. After 18 months, a copycat starting today has 18 months of catching up to do.

Memory compounds

Every conversation refines what Kai knows about your business, your clients, your voice.

Apps compound

Each App you build is one more piece of software your competitors using generic SaaS don't have.

Automations compound

Every workflow you describe is one more thing that runs without you.

Data compounds

Clients, contacts, documents, meeting transcripts, social mentions — all linked, all searchable.

The reasons

EVERY REASON YOU
DIDN'T START. GONE.

Every solo professional has the same mental list of reasons they haven't started the side business, the second company, the productized service. Most of those reasons were real until last year. None of them are real anymore on Kaiday.

“I don't know how to code.”

Kai is the developer. You describe; it ships.

“I can't afford to hire anyone.”

Kai is the team. Marketing, ops, support, dev — one assistant.

“Marketing is overwhelming.”

Kai drafts social, emails, campaigns. You approve and ship.

“My brand looks too small to trust.”

Your own domain, your own apps. You look like a 50-person company.

“My inbox would bury me.”

Kai handles routine threads and flags only what needs you.

“I don't have time alongside my day job.”

Kai works the night shift. You decide in 15-minute windows.

“I don't know where to start.”

Ask Kai. 'What should I build first?' — it's already paying attention.

“If everyone uses AI, my edge disappears.”

Your context is yours. Copycats start at zero. You compound.

You can keep waiting for permission.
Or you can describe what you want to Kai and start.
