Long chats. One short summary.

Blurb turns bursts of message notifications into one short summary. When a conversation goes quiet, Blurb reads what arrived and replaces the pile with a single notification that gives you the gist. Expand it to read the original messages, or tap it to open the chat.

HOW IT WORKS

Waits for a chat to pause, then sums it up in one notification
New replies join the unread summary, which updates after the next pause
Expand a summary to see the original messages
Every summary is kept on your phone, newest first

WORKS WITH YOUR APPS
Google Messages is free. Signal, WhatsApp, Discord, Microsoft Teams and Telegram are included with Blurb Pro, a one-time purchase with no subscription.

YOU CHOOSE WHERE SUMMARIES HAPPEN

On your phone: download Gemma 4 E2B (2.6 GB) or E4B (3.7 GB) once and summaries run offline, powered by LiteRT-LM. Needs a capable phone.
In the cloud: use your own API key for Gemini, OpenAI or Anthropic, or your own HTTPS server. Cloud summaries are generally higher quality.

PRIVACY

In on-device mode with cloud fallback off, message text never leaves your phone
No account and no ads
No Blurb server: cloud requests go straight from your phone to the provider you pick
Optional redaction removes phone numbers, emails, links and other identifiers before a cloud request (best effort)
Usage diagnostics never include message text, summaries or contact names, and you can turn them off in Settings

GOOD TO KNOW
Blurb needs notification access to read incoming message notifications and requires Android 12 or newer. Summaries are AI-generated and can miss details, so open the conversation for anything important.
