Assistants

Assistants in Devic are conversational interfaces that interact in real time with users (people or systems) to solve questions, execute actions, and deliver results within the same conversation thread. They rely on three main building blocks:
  • An LLM model — the understanding and generation engine.
  • A prompt (System Instruction) — the assistant’s context, rules, and voice.
  • A set of tools — the actions it can invoke during the conversation.

How We Understand Them in Devic

Unlike agents, whose cycle is autonomous and aimed at completing a task from start to finish, assistants are optimized for continuous dialogue: they listen to messages, reason and respond instantly, and can also execute tools when needed (query RAG, send an email, query a database, etc.). The result is an interactive, user-driven experience with on-demand action capabilities.

​
Functional Structure

An assistant combines:
ElementDescription
Prompt (System Instruction)Defines its purpose, style, limits, and response policies.
LLMInterprets the message, reasons, and drafts the response.
ToolsAccess data or execute actions (RAG, emails, databases, spreadsheets, MCPs, etc.).
RAG (optional)Document source used to ground and contextualize responses with your domain information.
This combination allows the assistant to answer accurately and, when needed, take action through tools without leaving the chat.

​
Interaction with Assistants

Interaction with assistants is synchronous and continuous: each user message can trigger reasoning and tool calls, returning an immediate response.

​
Common Usage Channels

  • Web widget embedded in your app or portal.
  • API to integrate it into other conversational flows or products.

​
Conceptual Example

A support assistant can:
  1. Read the user’s question about a procedure.
  2. Query RAG to find the relevant section of the manual.
  3. Reply with the steps and, if appropriate, send a PDF or open a related task.
  4. Maintain context for follow-up questions within the same thread
During the process, the assistant decides whether it needs a tool (e.g., “Search knowledge”, “Databases”, or “Send email”) and how to combine it with its response.

In Summary

FeatureAssistants in Devic
InteractionReal-time, continuous conversation.
GoalSolve questions and execute actions within the thread.
BehaviorUser-driven; can invoke tools on demand.
DesignConversational, with per-thread persistent context.
ComponentsPrompt + LLM + Tools (+ optional RAG).
Assistants are ideal for user support, internal help desks, and conversational front-ends.
By combining conversation with tools and RAG, they deliver precise answers and can act without leaving the chat.

Next Steps

Deploy Your First Assistant

Create an assistant step by step: prompt, model, tools, and RAG.

Assistant Prompt

Define the assistant’s voice, scope, and rules.

Tools

Connect native tools and MCPs so the assistant can take action.

RAG

Add documents to contextualize responses with your domain content.
