Getting Started

This walks through the first few minutes with MasterOS Personal: creating an account, sending a chat message, and asking a question about a file you upload.

1. Create an account

Sign up with email/password, or continue with Google or Facebook. Every self-registered Personal user belongs to the same shared organization — there's no separate "create your org" step for this edition.

2. Send your first chat message

Open Chat and pick a model tier from the model picker — fast, standard, or premium (see Switch model tiers for what each tier means and what your plan allows). Type a message and send it. The reply streams in, and the message's token cost is recorded against your daily quota (see Check your quota and add credit).

3. Upload a file and ask about it

Use the file attach action to upload a document (.txt, .md, .pdf, or .docx, up to 20 MB). MasterOS scans it, extracts its text, and makes it available so you can ask questions about its contents in chat — see Ask questions about a file for the full flow and current limits.
