Can Mymind be vibe coded?
A private, single-user place to dump links, images, notes and screenshots that tags and organizes itself so you never file anything.
The mechanic is honestly simple: capture a thing, extract text and metadata, ask a model for tags, embed it, then search across everything. An agent can build that in a focused implementation with SQLite, a headless browser for page snapshots and one model API call per item. What you cannot one-shot is the capture surface, which is the entire product in practice: browser extensions for three browsers, an iOS and Android share sheet, and the reliability that makes you trust it with the thought you had in a queue. The taste also matters more than it should here, because the pitch is that you never organize anything, and a DIY version that mis-tags half your library quietly becomes a junk drawer. Fine build, real gaps.

The achievable core
- Captures URLs, images, highlights and notes into a local SQLite library, auto-extracts text and metadata, asks a model for tags and a one-line summary, then serves a visual masonry grid with semantic plus keyword search.
- Save links with full-page snapshots and fast local search.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- Real browser extensions and a mobile share sheet, so capture friction goes way up
- Image understanding that recognizes objects, art, color palettes and text in photos at Mymind's quality
- Sync across devices, plus offline capable native apps
- Serendipity features: the everything-search, the surfacing of old cards, spaced resurfacing
- The last 20 percent is sync, migration fidelity, speed, and edge cases.
- Connectors, OAuth flows, and vendor API changes require constant upkeep.

$12.99/mo
Because the value of a second brain is proportional to how little effort each save costs, and Mymind spent years shaving that cost down to one click from any device. A self-hosted clone tags almost as well now that models are cheap, but it lives on your laptop behind a localhost URL, which means the thing you saw on your phone at 11pm never makes it in. People also pay for the privacy stance and the promise of no social features, no sharing, no feed, which is easy to replicate technically and hard to replicate as a trust relationship.

Build brief — a focused alternative to Mymind
Context
Mymind — A private, single-user place to dump links, images, notes and screenshots that tags and organizes itself so you never file anything. It currently costs $12.99/mo.
The mechanic is honestly simple: capture a thing, extract text and metadata, ask a model for tags, embed it, then search across everything. An agent can build that in a focused implementation with SQLite, a headless browser for page snapshots and one model API call per item. What you cannot one-shot is the capture surface, which is the entire product in practice: browser extensions for three browsers, an iOS and Android share sheet, and the reliability that makes you trust it with the thought you had in a queue. The taste also matters more than it should here, because the pitch is that you never organize anything, and a DIY version that mis-tags half your library quietly becomes a junk drawer. Fine build, real gaps.
This brief describes a focused, single-operator replacement for the part of Mymind that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
Captures URLs, images, highlights and notes into a local SQLite library, auto-extracts text and metadata, asks a model for tags and a one-line summary, then serves a visual masonry grid with semantic plus keyword search.
Save links with full-page snapshots and fast local search.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Node 20 and pnpm, runs locally.
Playwright with Chromium for page snapshots and screenshots.
Local disk for original images and thumbnails.
Optional: Tesseract for OCR on screenshots.
A browser extension loaded unpacked in dev mode.
Data and integrations
An LLM API key for tagging and embeddings, in .env.
Each of these needs a real account, credential, or quota. Set them up before writing feature code.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build a local-first personal "everything bucket" web app called Mind. Single user, no accounts, no telemetry, no cloud.
Stack, no substitutions:
Node 20, TypeScript, Next.js App Router, Tailwind.
SQLite via better-sqlite3, with sqlite-vec for vector search. One file at ./data/mind.db.
Playwright (Chromium) for page fetch, readable text extraction and a 1200px-wide screenshot.
One LLM provider read from .env: MODEL_API_KEY, MODEL_BASE_URL, MODEL_NAME, EMBED_MODEL. Never hardcode keys.
Data model: cards table with id, kind (link | image | note | highlight), url, title, author, siteName, textContent, aiSummary, colorHex, createdAt, favicon path, imagePath, thumbPath. Separate tags table and card_tags join. Separate embeddings virtual table keyed by card id.
Capture:
POST /api/capture accepts { url } or { text } or a multipart image upload.
For a URL: fetch with Playwright, extract main text, title, site name, favicon, save screenshot and a thumbnail.
For an image: store the original, generate a thumbnail, run OCR with tesseract.js if available, and skip silently if it is not.
After extraction, one model call returns 3 to 6 lowercase tags plus a single sentence summary as strict JSON. Then one embedding call over title + summary + first 2000 chars of text.
Extract a dominant color from the image or screenshot and store it as colorHex for the card background.
UI:
Home is a masonry grid of cards, newest first, image-forward, no folders and no manual filing anywhere in the app.
One search input at the top that does hybrid search: SQLite FTS5 over title/text/tags plus vector similarity, merged and deduped.
Clicking a card opens a detail sheet with the original link, full text, tags (editable) and a delete button.
Keyboard: "/" focuses search, "n" opens a quick note composer, Escape closes.
Also ship:
A bookmarklet and a minimal Chrome MV3 extension in ./extension that POSTs the current tab URL and any selected text to http://localhost:3000/api/capture.
A CLI: pnpm mind add URL_OR_TEXT.
A tiny import script that reads a Pocket or browser bookmarks HTML export and queues each URL.
Out of scope, do not build: multi-user auth, sharing, mobile apps, hosted deployment, sync between machines, payments.
Write a README with setup, .env.example, a seed script that captures five sample URLs, and make pnpm dev work on a clean clone.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Real browser extensions and a mobile share sheet, so capture friction goes way up.
Image understanding that recognizes objects, art, color palettes and text in photos at Mymind's quality.
Sync across devices, plus offline capable native apps.
Serendipity features: the everything-search, the surfacing of old cards, spaced resurfacing.
Someone else's ongoing judgment about what a good tag actually is.
What you still own after launch
Secure credentials, rotate secrets, and handle provider rate limits.
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Maintain every third-party integration as APIs and OAuth rules change.
Risk
Operational risk. The code is achievable; dependable data, integrations, and ongoing operations are the real cost.
Editorial confidence in this assessment: medium. No reviewed project implementation is linked yet.
