About AI assistants
What is an AI assistant?
An AI assistant is multi-turn: it holds a conversation, follows a persona, and calls skills when relevant to work with you step by step — the thing most people picture when they say 'an AI'.
Every assistant's page shows an example of it at work, the skills and tools it uses, and the documents it will ask you for, so you know how it behaves before you buy.
Compare assistants by the job they help with, the model they were tested on, and price — then start a conversation and put it to work.
People searching for AI assistants usually want a ready-to-use chat helper for a specific job, with a clear sense of how it behaves before they commit.

01
Multi-turn conversation
An assistant holds context across a whole conversation and works with you step by step, rather than answering one prompt in isolation.
02
A voice and rules
Its prompt sets its tone and rules, and its seller can give it a persona, so it behaves the same way every time you talk to it.
03
Skills it can call
Assistants pick up skills when relevant, so they can do specific jobs — format, convert, follow a procedure — not just chat.
04
An example first
Each listing shows an example of what the assistant returns, so you can see how it responds before you buy.
An assistant is one of several AI building blocks on Sigrix. Here is how it differs from the others:
Prompt
A single message. An assistant is a whole conversation that remembers context.
Persona
A kind of prompt: the character layer an assistant wears. The assistant is the working chat experience built around it.
Assistant
A multi-turn chat helper that works with you, follows a persona, and calls skills when relevant.
Agent
Works for you autonomously. An assistant works with you, turn by turn.
