The problem
96
times a day you check your phone. Most of it is noise.

Telegram pings. Slack threads. Gmail follow-ups. WhatsApp groups. LinkedIn messages. Every app fights for your attention, but only a few messages actually need you right now. There's no single place that answers: “What actually needs my attention?”

The solution

One smart inbox. 20 apps. Zero cloud.

CueInbox captures notifications from all your messaging and productivity apps, runs them through AI that understands urgency, context, and intent — and presents a single priority queue.

⚖

Triage

AI classifies every notification into Now, Today, Delegate, or FYI. VIP contacts always surface. Noise gets filtered.

✎

Reply

3 contextual reply options per message using the last 5 messages of conversation. Concise, warm, or direct. Tap to send.

⏰

Remind

Snooze any thread with AI-suggested timing. Get reminded when it matters, not when it arrives.

Under the hood

AI that actually reasons about your messages.

Every notification passes through a two-stage pipeline — instant heuristics first, then on-device LLM for hard cases. Chain-of-thought reasoning activates when confidence drops below 70%.

Chain-of-thought reasoning activates automatically when confidence < 0.7 — the model explains its reasoning before scoring. Vision analysis runs on notification images and photo previews for richer context.

“Finally an app that just works across all my messaging apps. The AI triage is surprisingly accurate — it correctly prioritized a critical work Slack message over a meme from a friend.”

FAQ

Common questions.

CueInbox uses a two-stage approach: lightweight heuristics run instantly on the CPU for every notification. The Gemma 4 E2B model only activates when deeper analysis is needed (typically 10–30% of notifications). In practice, battery impact is comparable to having Telegram running in the background. The model doesn't run continuously — it processes one notification at a time and then releases GPU resources.
Android 13+ (API 33) with an arm64 processor and GPU. This covers the vast majority of Android phones released after 2020, including all modern Samsung Galaxy, Pixel, OnePlus, and Xiaomi devices. The LiteRT-LM SDK requires GPU acceleration — devices without a supported GPU fall back to heuristic-only triage without the LLM features.
Yes — fully. The only time you need internet is the initial one-time model download (~2.4 GB over Wi-Fi). After that, triage, draft replies, reminders, and all AI features work completely offline. No API calls, no cloud sync, no telemetry.
CueInbox requests Android notification access — the same permission that allows a Wear OS watch to mirror your phone's notifications. It reads notification text, sender names, and optionally attached images. All of this data is processed locally and stored in an encrypted on-device database. Nothing is transmitted anywhere.
The app itself is under 30 MB. The Gemma 4 E2B model file is ~2.4 GB and downloads once on first launch over Wi-Fi. After that, no additional storage is used unless you accumulate a large notification history (which can be cleared in Settings).
No. CueInbox never sends anything without your explicit tap. Draft replies are suggestions — you review them, edit if needed, and choose to send. The app has no ability to send messages autonomously.

Take back your attention.
