A Flutter app that collects the day's tech news +from German and English RSS/Atom feeds and uses AI to summarize single articles +or write a daily briefing. It's meant to replace the n8n → Discord workflow. + +## Features (prototype) + +- **Today**: all articles from the enabled sources in the last 12/24/48 h, newest + first. Filter by language or source, pull to refresh. +- **Reading in the app**: tapping an article opens a clean **reader view** (text, + headings, lists, quotes, images) without ads or cookie banners. The globe icon + switches to the **original page** in an in-app WebView, for paywalls or sites + that block reader view. **Summarize with AI** uses the same downloaded text, so + the summary is based on the full article, not just the RSS teaser. Links in the + briefing open the same way. +- **Briefing**: AI picks the 6–10 most important stories of the day, merges + coverage from different outlets, and links every topic to its sources. Every + briefing is saved on the device (`briefings.json` in the app's private + storage); the history button lists them by month, tap to read, swipe to delete + (with undo). +- **Paid articles and ads hidden**: heise+ and Golem `(g+)` are recognized by + their title; SPIEGEL+ and t3n Pro by a marker in the article page, which the app + checks once per new article in the background (it reads only until the marker, + and remembers results for 14 days). Sponsored posts (`Anzeige:`) are hidden too. + The feed header shows how many were hidden; both filters can be turned off. +- **Ad and cookie-banner blocking** in the original-page view: requests to ~80 + ad/tracker hosts and the common consent managers (Sourcepoint, OneTrust, + consentmanager, Usercentrics, Didomi, Cookiebot, …) are blocked, and a + stylesheet hides leftover ad slots and banners. Nothing is accepted, so sites + treat it like a rejection. Golem redirects to a separate consent page instead + of showing a banner; with "Accept cookie walls" on (default), the app makes the + same request as Golem's own "Zustimmen" button (`/abo/setconsentcookie.php`, + valid for a day) and reuses the cookie for reader view and the in-app page. + With it off, the app shows the teaser and an "Open website anyway" option. +- **Sources**: 21 curated feeds (12 German, 9 English), toggle each one, or add any + RSS/Atom feed (it's validated before being added). +- **Dark mode**: System / Light / Dark in Settings (applies instantly). The + original-page view follows it too: when the phone is dark, sites use their own + dark design or Android darkens them; when only the app is dark, the app inverts + the page colours and keeps photos and videos as they are. +- **Settings**: AI provider (off / Claude API / n8n webhook), model, summary + language (German/English, whatever the source language), time window, paid/ad + filters, ad and cookie-banner blocking. + +## Running + +```bash +flutter pub get +flutter run # pick an Android emulator/device +flutter test # unit tests (parser, Claude request/response handling) +LIVE_FEEDS=1 flutter test test/live_feeds_test.dart # checks every real feed +``` + +Platform notes: + +- **Android / iOS**: work as-is (Android 6.0+). +- **Windows desktop**: requires Visual Studio with the "Desktop development with + C++" workload. Reader view works; "original page" opens the browser because + the WebView plugin has no Windows support. +- **Web**: browsers block cross-origin feed requests (CORS). Set a CORS proxy + prefix in Settings (only shown on web), or use the app on mobile/desktop. + +## AI setup + +### Option A: Claude API (direct) + +1. Create a key at . +2. Settings → AI summaries → **Claude API** → paste the key → Save. + +The key is stored in the platform keystore (`flutter_secure_storage`) and only +sent to `api.anthropic.com`. Model choices: + +| Model | Use it for | +|---|---| +| `claude-opus-5-5` (default) | Best briefing quality | +| `claude-sonnet-5-5` | Balanced cost and quality | +| `claude-haiku-5-5` | Cheapest; good enough for single-article summaries | + +Requests use low effort (summarizing is routine work) and, for the briefing, +structured JSON output so the result maps reliably to topics and links. On Opus +and Sonnet the app also enables Anthropic's server-side refusal fallback +(`fallbacks: "default"`): if a safety classifier declines a request, the API +retries it on a fallback model. + +> Shipping the app to other people with your key inside isn't safe. For +> personal use a key you entered yourself is fine; for distribution, route +> requests through your own backend (e.g. the n8n option below). + +### Option B: Your n8n workflow + +Settings → AI summaries → **n8n webhook** → enter the production URL of a +*Webhook* trigger node (method POST, "Respond: Using 'Respond to Webhook' node"). +The app sends JSON and expects JSON back. + +**Daily briefing** + +```jsonc +// Request +{ + "action": "daily_briefing", + "language": "de", // "de" | "en" + "articles": [ + { + "id": "a1", + "title": "…", + "url": "https://…", + "source": "heise online", + "language": "de", + "published": "2026-10-11T07:30:00.000Z", + "excerpt": "…" + } + ] +} + +// Response, option 1 (structured; topics link back to the articles) +{ + "intro": "One or two sentences on the day.", + "topics": [ + { "title": "…", "summary": "…", "article_ids": ["a1", "a7"] } + ] +} + +// Response, option 2 (plain text, e.g. your existing Discord message) +{ "text": "…" } +``` + +**Single article** + +```jsonc +// Request +{ + "action": "summarize_article", + "language": "de", + "article": { "title": "…", "url": "…", "source": "…", "published": "…", "text": "extracted article body" } +} + +// Response +{ "summary": "…" } // a plain-text body also works +``` + +Use a *Switch* node on `{{$json.body.action}}` to route the two cases to your +existing AI nodes. + +## News sources + +Every feed URL below was checked to load and parse.
