A small overlay that listens, looks, and answers.
Nullside is a control bar and a chat panel that float above every app, including full-screen ones. Everything starts from the keyboard.
The shortcuts
Show or hide Nullside
The overlay appears over whatever you're doing, and disappears just as fast. There's no Dock icon, so this is the way in.
Start listening
Nullside transcribes both sides of the call as it happens: your mic, and the other people's audio.
Answer now
It reads the conversation and your screen, and writes what to say next. With auto-answer on, it does this by itself.
Click-through
Clicks pass through the overlay to the app beneath, so it can stay on screen while you work.
New chat
Start fresh for the next conversation. You can also type a question into the chat at any time, or send a screenshot.

Asked a question? It's already answering.
With auto-answer on, Nullside notices when the other person has asked you something and answers it without a keypress. It's one switch on the bar.
One mode per situation.
Switch modes before a call and Nullside answers the way that conversation needs. Each mode has three parts.
Instructions
How answers should sound: short or detailed, formal or casual, what to focus on.
Notes
Short background: talking points, product facts, the role you're interviewing for.
Documents
BETAWhole files: a thesis, papers, a resume, a product guide. PDF, Word, RTF or text. Answers cite the page.
On your screen. Nowhere else.
The overlay uses macOS's own window protection. When you share your screen, the people you're talking with see your normal screen.
