One story, reported three ways
Related coverage is folded together by meaning…
Local-first personal reader
Read quietly.
Keep what matters.
Rinwa groups duplicate reporting by meaning, finds ideas even when the words differ, and lets translation settle beneath the original. Your library stays local and readable without an account.

Notes on a small, open web
The links we keep become a map of what mattered…
SQLite, indexes, and the long view
Why a database on your own device still matters.
A room made for attention
The best reading tools disappear. They hold the text still and let understanding arrive at its own pace.
A good reading room does not compete with the page. It softens the edges of the world until only the words remain.
好的阅读空间不与页面争夺注意力。它让世界的边缘渐渐柔和，直到眼前只剩文字。
Images keep their place. Lists keep their rhythm. Code remains exactly what the author wrote.
图片留在应有的位置，列表保有原来的节奏；代码则完整保留作者写下的样子。

Two things, done unusually well
Less repetition.
Less distance from the original.
Rinwa does not put an AI dashboard beside your reading. It uses intelligence in two places where it can make the page quieter: organizing meaning, and crossing language.
01 · LOCAL SEMANTICS
One story,
One story,
not ten.
Embedding similarity recognizes the same event across different headlines and sources. Recent coverage folds into one expandable story; natural-language search brings back passages even when you cannot remember the original words.
Embedding Is All You Need — to find your way back through what you read.

02 · IMMERSIVE TRANSLATION
The original stays.
The original stays.
Translation follows.
The source paints immediately. Translation arrives block by block without flattening lists, moving images, or touching code. Translate the whole article—or only the sentence you selected.
- Original first, always readable
- Structure-preserving inline translation
- Chinese, code, dates, numbers, and URLs skipped
Reading tools should leave the page intact.
A reader should preserve the shape of an argument. Lists keep their rhythm, images keep their place, and the original remains the point of reference.
阅读器应当保留论述原有的形状。列表维持节奏，图片留在应有的位置，原文始终是理解的参照。
const source = article.original;SELECTED SENTENCEthe original remains the point of reference.原文始终是理解的参照。
Original readyTranslation follows asynchronously
One reading surface
Many sources.
One quiet rhythm.
Feeds, web pages, and built-in video sources do not become separate silos. RSS and the early Connector foundation enter one local content layer and share the same extraction, translation, search, highlighting, and note tools.
Sources enter Rinwa
Independent publishing, on your time.
Follow blogs, newsrooms, and changelogs while preserving authors, dates, source links, and feed content.Read
The original arrives first.
Translation appears block by block without replacing or delaying the source. Code, dates, numbers, links, and already-Chinese text stay untouched.
Organize
A search can become a living feed.
Search articles, notes, and highlights locally. Save the conditions and the result stays in the sidebar, collecting what you care about over time.
Remember
Reading should leave more than a status.
Highlights use quote context to relocate after re-extraction—or stay honestly unanchored. Notes, tags, references, and Obsidian Markdown remain durable user data.
Search your understanding
Find more than words.
Find what you understood.
Rinwa combines local full-text indexing with optional multilingual vector retrieval. Models, indexes, and articles stay on-device. If a model is unavailable, search falls back quietly instead of breaking your library.
- ✓ Articles, notes, tags, and highlights together
- ✓ FTS + dense retrieval + RRF ranking
- ✓ Visible download, indexing, pause, and rebuild states

SQLite WAL Mode Can Lock Short-Lived Readers
…a local database does not mean giving up sync. It means every device first owns a library that can work by itself.
Lobsters · 3 hours agoYour note86%
Sync operations, not the entire database file. Each device keeps its own media and indexes.

Keep what matters
Your knowledge should not belong to a subscription.
Articles expire and services change. Your notes should not. Rinwa treats highlights, tags, references, and edited summaries as user data, never as disposable AI cache.
“A good reading room does not compete with the page.”
好的阅读空间，不与页面争夺注意力。
MY NOTE
Calm is not the absence of features. It is making them appear only when needed.
Local first, honestly
The cloud may help. It should never be a prerequisite for reading.
SQLite on every device
Subscriptions, articles, media, and indexes live locally first. Saved reading continues offline.
Sync operations, not database files
Optional Rinwa Sync exchanges selected states and operations while every device keeps an independent library.
App updates do not clear content
Extraction, translation, and summary caches have separate versions. A failed refresh preserves the last successful result.
An exit route stays open
OPML, Obsidian, and encrypted full backups keep subscriptions and knowledge portable.
Under the reading surface
Technical when it matters.
Invisible when it does not.
Rinwa keeps the reading surface calm, but the boundaries underneath are explicit: local ONNX search, provider-aware AI, and operation-log synchronization.
LOCAL SEARCH01
FTS + ONNX embeddings
A pinned EmbeddingGemma model runs locally. Sparse and dense ranks meet through RRF; failure returns to full-text search.

Open DocumentationOne interface, many screens
One reading surface across your devices.
React and Tauri 2 let platforms share the interface and reading logic. When a native capability is not ready, Rinwa says “in development” instead of showing a false green checkmark.
macOSPrimary target
Designed for keyboards, trackpads, and long reading.
Native windows, hierarchy swipes, directory picking, secure storage, and in-app web windows are in the desktop shell.

How are Rinwa and Luma related?＋
Rinwa is the next-stage brand. The current application and preview package still say Luma. The migration will preserve bundle identity, backup formats, and secure-storage compatibility.
Do I need Rinwa Sync?＋
No. The open-source client and a single-device SQLite library work without a paid service. kappain plans to offer managed Rinwa Sync as an optional subscription; self-hosting remains part of the architecture.
What is open source, and what is paid?＋
kappain develops Rinwa as an open-source reader. Reading, local storage, import and export are product foundations; the commercial service is convenient hosted synchronization and its operations, not ownership of your library.
Where do translation and chat send article text?＋
Only to the provider you configure, and only after explicit data-sharing consent. A self-hosted OpenAI-compatible proxy is supported.
Is it ready to replace my daily reader?＋
macOS is the primary quality target, but the product is still a development preview. Start with a subset of feeds and keep your current reader nearby; OPML export and backups are available.
