Nexa Assistant Overview

Nexa Assistant is a browser-based AI chat application. There's nothing to install — you sign in, pick a model, and start chatting.

Key features

• Streaming responses — replies appear as they're generated rather than all at once
• Multiple models — six free models and four Pro models, each suited to different kinds of tasks (see Models)
• Adjustable effort — a Low / Balanced / High effort setting that trades response depth for speed
• Memory — the assistant can remember specific facts across chats (see Memory)
• Image attachments — attach an image to a message on supported models
• Chat history — previous conversations are kept in a sidebar you can return to

Signing in

You can create an account with Google Sign-In or with an email and password. Your account determines your daily message limit — see Accounts & Limits.
