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 on Sigrix ships with its persona, its list of skills, and sample dialogues so you know exactly 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. Popular searches: ai assistant marketplace, buy ai assistant, custom ai assistant, ai chat assistant, ai assistants for business. Related: ai agents, ai personas, prompts, chatbot, ai skills.

What's inside an AI assistant

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 persona inside
Each assistant ships with a persona — tone, rules, and point of view — so it behaves consistently 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
Sample dialogues
Listings include example conversations, so you can see how the assistant responds before you buy.

Assistants vs agents, prompts & personas

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
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.

An AI assistant is a configured, multi-turn chat helper: it holds a conversation, follows a persona, and calls skills when relevant to work with you step by step on a specific job.

An assistant works with you in a back-and-forth conversation. An agent works for you autonomously — you set a goal once and it executes the steps on its own without turn-by-turn input.

Assistants on Sigrix compile into a persona plus skills you can run on the major models. Each listing shows the model the creator tested the assistant on.

Some assistants are free to claim and others are paid — each assistant's price is shown on its card and detail page. Either way you own an editable copy once you claim it.

Yes. Approved sellers can publish assistants on Sigrix: configure the persona, add skills and sample dialogues, set a price, and list it. See the Sell page to get started.
