AI-powered read-later app

Don’t just bookmark it. Understand it.

Save an article and Semnas reads it with you. You get a summary, the key points, an audio version you can listen to, and answers when you ask it questions. The more you read, the better it knows what to put in front of you next.

Brief

The unread pile, one summary at a time

Brief turns the backlog into a short queue. Listen or skim, mark it and move on, and star the few worth reading properly.

Reader

A summary on top, and an audio version to play

Every saved article opens with an overview and a narrated version, so an 8-minute read can be a 90-second listen when that is all you have.

Margin

Key points written beside the passage

Summarize a section, pull out its key points, check its reading level or add your own note. It all sits in the margin next to the text it came from.

Ask about the whole piece or only the passages you selected, and get an answer grounded in the text in front of you.
