Memo — a Notion-style note-taking app, built entirely by AI agents.

About

Memo is the product being built during the Software Factory build-in-public sprint (April 13–25, 2026). The goal: ship a functional, polished note-taking app in two weeks — without a single line of human-written code.

Every line of code in this repository — every PR, every commit, every migration — is written by AI agents using Ona. Humans provide intent and direction (what to build, feature priorities, design decisions). Agents handle everything else: architecture, implementation, testing, code review, and deployment.

The repo is public so anyone can follow along, inspect the code, and see how an AI-driven software development lifecycle works in practice. The live app is at memo.software-factory.dev.

Live streams

The build process is streamed live daily during the sprint.

• Schedule: weekdays, 5 PM BST / 12 PM ET / 9 AM PT
• Week 1: April 13–17 · Week 2: April 21–25
• Where to watch:YouTube (@ona_hq), X (@ona_hq), X (@swfactory_dev)

Past streams are available on the YouTube channel.

Stack

• Next.js 16 (App Router) + React 19 + TypeScript
• Tailwind CSS + shadcn/ui
• Lexical (rich text editor)
• Supabase (PostgreSQL, Auth, Realtime)
• Sentry (error tracking)
• Vitest + Playwright (testing)
• Deployed on Vercel

Getting started

The fastest way to run Memo is in an Ona. Click the badge above, or:

1. Add this repository to an Ona project
2. Configure the required project secrets (see below)
3. Open the environment — dependencies install automatically and the dev server starts on port 3000

Required project secrets

Set these in your Ona project settings under Secrets:

Secret	Description
NEXT_PUBLIC_SUPABASE_URL	Supabase project URL
NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY	Supabase anon/public key
SUPABASE_SECRET_KEY	Supabase service role key
NEXT_PUBLIC_SENTRY_DSN	Sentry DSN (optional — leave empty to disable)
SENTRY_DSN	Sentry server-side DSN (optional)
SENTRY_AUTH_TOKEN	Sentry auth token for source maps (optional)
SENTRY_ORG	Sentry organization slug (optional)
SENTRY_PROJECT	Sentry project slug (optional)

Without Supabase secrets, the app starts but auth and data features won't work.
