New Chat
To start a conversation with an AI agent, you first need to choose which one you want to talk to. Platica shows you every agent available and lets you mark favorites so you can quickly access the ones you use the most.
Start a Chat
Click "+ New Chat" in the left sidebar or the green "+ New chat" button in the top right corner.
You'll see the "Which agent do you want to talk to?" screen with cards for every agent available.
Click the agent you want. A checkmark ✓ will appear and the agent's name will show up in the text field as
@AgentName.Type your message and hit send to start the conversation.
Agent Cards
Each agent is shown as a card with the following elements:
| Element | Description |
|---|---|
| Avatar | Image of the AI agent |
| Name | Agent's name |
| ☆ Star | Marks or unmarks the agent as a favorite |
| ↗ Arrow | Selects the agent directly to start the conversation |
Click the arrow ↗ or anywhere on the card to select the agent. Once selected, a ✓ will appear and you can start writing to them in the text field.
Favorite Agents
Mark agents as favorites by clicking the star ☆ on their card. The star will turn gold ⭐ to indicate it's a favorite.
What are favorites for?
Once you're inside an active conversation, you can switch agents from the @AgentName ∨ dropdown in the text field. In this selector, agents are organized into two groups:
- FAVORITES — The agents you marked with ⭐ show up first
- OTHER AGENTS — The rest of your available agents
This is ideal if you have many agents but only use a few of them frequently.
The FAVORITES and OTHER AGENTS section only appears in the agent selector inside an active conversation, not on the initial agent selection screen.
Search Agents
If you have many agents configured, use the "Search agents" field at the top of the selector to quickly find the one you need by name.
The "View 30 more agents ∨" link expands the full list if you don't see the agent you're looking for among the initial cards.
Create a New Agent
If you need an agent that doesn't exist yet, you can create it directly from this screen by clicking the "New agent" card with the green icon. This will take you to the AI Agent Builder, where you can configure your new agent from scratch.
After creating a new agent, it will automatically show up in the list of agents available for chat. You can return to Chats and start testing it right away.
Edit an Agent from Chats
During an active conversation, the settings icon to the right of the text field takes you directly to the AI Agent Builder for the agent you're talking to. From there you can modify its instructions, knowledge, and configuration, and test it in the built-in simulator.
This flow lets you iterate quickly:
- Chat with the agent in Chats
- Identify something that needs adjusting
- Edit by clicking the settings icon
- Test the changes directly in the editor or go back to Chats
