Who do you trust in Silo?

Your Silo space is ready, with your discussion ideas and two phrases for comparing theories. I’ve added the no-spoilers preference to its context.

Spaces & saved phrases

Your words, ready for every room.

Keep a space for family, friends, work, or your book club, each with its own phrases and notes. Pin the words you use most and give longer phrases short codes — two letters can be a whole sentence.

Switch spaces, then try one of the codes shown below the composer.

Codes here: trip → Let’s make a weekend of it. · film → I’m choosing the film. · cm → I’ve changed my mind.

Notes & Present

Longer thoughts, ready ahead of time.

A story for your kids, a family celebration, a pitch for your next project. Write it once, read it aloud in your voice, or share it as a file.

Play the story, or press Present to hear it one passage at a time.

Bedtime story — the island adventure

The four of them rowed out to the island, with Scout barking at the waves. Inside the cave, Jo’s torch lit up an old wooden chest. “Treasure,” whispered Ben. “Real treasure!” But behind them, something moved in the dark…

About

Type words, not keys.

I’m Ravi. I was diagnosed with ALS in 2019. Clicks are precious when you type with your eyes or a head mouse. I want each one to carry more of what I mean to say.

Saved phrases and simple text expansion only go so far. A conversation keeps moving: you respond, change your mind, make a joke, say something you’ve never said before. Your communication app needs to move with you.

September is my attempt to build a dynamic, fully customizable AAC alternative around that need. The goal is to help you choose words and shape whole thoughts with fewer keystrokes, in your own voice, on your own terms.
