AI PERSONAS

Personas are pre-configured AI assistants tuned for specific tasks. Instead of manually setting a system prompt and temperature every time, pick a persona and start working. Each persona sets the system prompt, temperature, and recommended model automatically.

Think of personas as ChatGPT's "GPTs" but running on your private server. Your data never leaves your infrastructure.

Using a Persona

Go to Personas

Navigate to Dashboard → Personas.

Browse and Select

Browse built-in personas or filter by category (Business, Technical, Creative). Each card shows the persona's description, suggested model, and temperature.

Click Use

Click Use → on any persona. You'll be taken to the Chat page with the persona's system prompt, temperature, and model pre-loaded.

ℹ

The persona configuration is applied for the current chat session. Starting a new chat resets to defaults. You can manually adjust the system prompt and temperature in Chat Settings at any time.

Creating Custom Personas

Create personas tailored to your team's specific workflows.

Click Create Persona

On the Personas page, click + Create Persona.

Configure

Set the icon, name, description, system prompt, temperature, and suggested model. The system prompt is the most important part — it defines how the AI behaves.

Save and Use

Click Save Persona. Your custom persona appears in the grid under the "Custom" category.

✓

Good system prompts are specific. Instead of "You are a helpful assistant", try "You are a contract review specialist for an Indian law firm. Review agreements for risks, missing clauses, and one-sided terms. Always flag indemnification and liability caps. Cite specific clause numbers."

Tips for Effective Personas

Tip	Why
Be specific in the system prompt	Vague instructions get vague responses. Define the role, output format, and constraints clearly.
Use low temperature (0.1-0.3) for factual tasks	Legal review, data analysis, and code review need precision, not creativity.
Use higher temperature (0.7-0.9) for creative tasks	Content writing, brainstorming, and email drafting benefit from more variety.
Match the model to the task	Use Qwen Coder for code, Phi-4 for reasoning, Qwen 3.5 for multilingual.
Include output format in the prompt	If you want bullet points, tables, or specific sections — say so in the system prompt.
