The verdict: can you vibe code Reflect?
Build a simplified web-only subset for personal use, or keep paying $10/mo; the Yjs CRDT local SQLite sync and zero-knowledge E2EE make a full clone a serious engineering undertaking.
Reflect looks simple on the surface, but replicating its architecture requires building a local-first offline SQLite engine paired with Yjs conflict-free replicated data types, zero-knowledge encryption keys stored entirely client-side, and multi-provider AI integrations. A solo developer can build a clean web-based subset with Next.js and Turso in a few weeks, but achieving the zero-knowledge E2EE sync and multi-platform native feel of Reflect takes months of tedious, unglamorous systems debugging.
Estimated effort: 3-4 months of part-time work

Build guide
01Project Scaffolding & Database Schema
Initialize a Next.js project with Tailwind CSS, configure Turso SQLite connection, and define database schemas for users, notes, backlinks, and daily journals.
Scaffold a new Next.js 16 project using TypeScript and Tailwind CSS. Configure Turso as the SQLite database connection using Drizzle ORM or native libSQL. Create database migrations and tables for `users`, `notes` (id, title, content, is_daily, date, created_at, updated_at), `backlinks` (source_id, target_id), and `tasks` (id, note_id, text, completed, due_date). Ensure strict TypeScript types and provide a clean connection utility file.02Authentication & User Management
Implement self-hosted authentication with better-auth to manage secure user sessions without external MAU pricing fees.
Integrate `better-auth` into the Next.js application to handle email/password authentication and secure session cookies. Create sign-in and sign-up pages with Tailwind CSS styling that match a minimalist dark-mode aesthetic inspired by modern PKM tools. Ensure database tables for sessions and users are automatically provisioned in Turso.03Rich-Text Editor & Backlink Parsing
Build a distraction-free note editor that parses bi-directional `[[backlinks]]` and automatically links notes as users type.
Build a rich-text note editing interface using Tiptap or a custom Markdown editor component. Implement real-time regex parsing for `[[note title]]` syntax to automatically detect and extract bi-directional backlinks as the user types. Create a backend API endpoint that scans note updates, extracts all backlink relations, and upserts them into the `backlinks` table so incoming and outgoing references render correctly at the bottom of each note.04Daily Notes & Calendar View
Structure notes around calendar dates to provide frictionless daily capture and a dedicated journal view.
Create a Daily Notes routing and view system in Next.js (`/notes/daily/[date]`). When a user visits today's date, automatically query or create the daily note record formatted as YYYY-MM-DD. Add a calendar sidebar component that lets users click any past or future date to jump straight to that day's journal entry, displaying associated tasks and meetings.05AI Assistant & Whisper Transcription
Integrate OpenAI API for voice note recording, speech-to-text transcription via Whisper, and LLM text transformations.
Implement an AI integration layer using the Vercel AI SDK and OpenAI API. Add a voice recording widget that captures browser audio blobs, sends them to a server action invoking OpenAI's Whisper API, and inserts the resulting transcript directly into the active editor cursor position. Build a floating command palette (`Cmd+J`) that allows users to highlight text, select custom AI prompt templates (e.g., summarize, fix grammar, add backlinks), and stream responses directly into the document.06Task Aggregation & Polish
Build a unified task view that aggregates checklists and to-dos scattered across daily and regular notes.
Build a dedicated Tasks view page (`/tasks`) that queries all checkbox and task items stored across every user note. Group tasks into sections for 'Today', 'Overdue', and 'Upcoming'. Implement interactive checkboxes that update the underlying note content in Turso in real time when toggled. Add polish including keyboard shortcuts (`Cmd+K` quick search, `Cmd+L` copy URL) and dark mode persistence.
