RedditTLDR adds a draggable floating bubble to the Reddit app. Tap it on any post — get a concise AI summary powered by Claude in about 3 seconds. No root required. No browser extension. Never leave Reddit.
Built for the official Reddit app. Works entirely on your device — your API key, your data.
Tap the bubble on any post. Get 1–7 bullets covering the key points in ~3 seconds.
Tap "Summarize comments" for a separate AI summary of the discussion thread.
Short (1–2 sentences), Medium (TL;DR + bullets), or Detailed (full context).
Haiku 4.5 (fastest/cheapest), Sonnet 4.6 (balanced), Opus 4.7 (highest quality).
Docks to either screen edge. Drag down to the dismiss target to hide it.
Copy the full post + comments summary as plain text with one tap.
API key stored with AES-256-GCM encryption. No analytics, no telemetry, no account needed.
Very long posts (6+ screens) show a banner so you know the summary may be incomplete.
| Requirement | Detail |
|---|---|
| Android version | Android 8.0 (API level 26) or higher |
| Reddit app | The official Reddit app from the Play Store (com.reddit.frontpage) |
| Anthropic API key | Get one free at console.anthropic.com. You pay Anthropic directly — Haiku 4.5 costs fractions of a cent per summary |
| Permissions | Accessibility Service, Display over other apps, Notifications (Android 13+) |
No Reddit API, no OAuth, no account needed. Just Android's accessibility layer and your own Claude key.
When the official Reddit app is in the foreground, the AccessibilityService automatically starts a foreground service that draws the draggable bubble.
The bubble becomes non-touchable so dispatched gestures pass through to Reddit. The extraction engine begins scrolling.
The app swipes up to the post top (max 5 swipes), then swipes down through the full post and comments (max 6 swipes), reading the accessibility tree after each step. A fingerprint hash confirms each swipe actually moved the page.
The captured text is sent to Anthropic's Claude API with a prompt that tells the model to summarize only the post body and ignore the comment section. The summary appears on the overlay card.
Tap "Summarize comments" on the card. Claude uses the already-captured text to summarize the discussion — no second scroll, no second API call.

Install RedditTLDR, grant Accessibility Service and overlay permissions, add your Anthropic API key in settings, then open the official Reddit app. A floating bubble appears automatically — tap it on any post to get an AI summary in about 3 seconds.
No. RedditTLDR uses Android's standard AccessibilityService and overlay APIs, available on any unrooted Android 8.0+ device. No root, no bootloader unlock, no special permissions beyond what Android provides natively.
The app is free and open-source (MIT license). You need your own Anthropic API key, and Anthropic charges for API usage at their standard rates. At Claude Haiku 4.5 rates, each summary costs well under $0.01.
Yes. After the post summary card appears, tap Summarize comments. The app uses the same screen-captured text to generate a separate summary of the comment discussion — no additional scrolling or network round-trip.
RedditTLDR uses AccessibilityService to read on-screen text from the Reddit app and dispatch scroll gestures. This is the only way to capture post content without a Reddit API integration. The service only activates when the Reddit app is in the foreground.
No. RedditTLDR is designed for the official Reddit app (com.reddit.frontpage). Third-party Reddit clients have different accessibility tree structures and are not supported.
