AI Tuning
AI Tuning lets you control how your interview agents behave, what they prioritize, what they evaluate, and how insights are generated.
Where to Find AI Tuning
Go to your Dashboard
In the sidebar, open AI
You'll see these sections:
Knowledge Base
Interview Templates
Interview Evaluation
Interview Integrity
Agent Library
Languages & Voices
Each one controls a different part of your AI agent’s logic and evaluation flow.
Company Context
This section tells the AI who you are and how candidates should experience your brand. Settings → Company Context
Company Identity
Visible to candidates and referenced by the AI during interviews.
Company Name: Shown in interviews and PDFs (max 25 characters)
Company Logo: Upload your logo (JPG, PNG up to 5MB) for interviews and reports
Outreach Settings
Controls how candidates receive interview links.
Default Interview URL: The base link candidates see in engagement messages
Interview Domain: Select from your configured domains
URL Slug: Customize the URL path for your company
Default Sender Email: Email identity for invites and reminders
Company Location
Company Address: Used for location context when the AI engages with candidates (helps answer location-related questions accurately)
Candidate Communications
How do I disable automated e-mail communication from HeyMilo?
Turn Off All Candidate Communications: Master toggle to disable all automated emails and SMS messages sent to candidates. Use this to pause all outreach when needed.
Why this matters:
Consistent branding improves candidate trust and reduces drop-off, especially in high-volume workflows.
Knowledge Base
This section lets you add reference points that help AI interviewers understand your company's preferences and context.
What is the Knowledge Base?
The Knowledge Base stores information that your AI interviewers can reference during interviews. This helps the AI:
Understand what you look for in candidates
Answer candidate questions accurately
Apply consistent evaluation criteria across interviews
Managing Knowledge Items
Click Add Knowledge to create a new item with:
Title: A descriptive name (e.g., "Candidate Experience Requirements")
Tag: Categorize by type:
General: Company-wide information
Candidate: What you look for in candidates
Job Posting: Role-specific context
Interviews: Interview process information
Content: The detailed information for the AI to reference
Active toggle: Enable or disable without deleting
Using Knowledge Items
Filter items by tag to find specific information
Toggle items on/off to control what the AI references
Edit or delete items as your needs change
Why this matters:
Knowledge items ensure your AI interviewers have consistent context across all interviews, reducing the need to repeat information in every interviewer setup.
Interview Templates
This section lets you create reusable interview configurations that can be quickly applied to new job postings. Set one as a default by starring a template!
What are Interview Templates?
Interview Templates save your interview setup (questions, settings, screening criteria) so you can reuse them across multiple roles without starting from scratch each time.
Each template includes:
A unique template code for easy reference
All interview configuration settings
The ability to set one template as the default for new interviewers
Managing Templates
Create Template: Click "Create Template" to build a new reusable configuration
Use Template: Apply a template to quickly create a new interviewer
View: Preview the template's configuration without editing
Edit: Modify an existing template's settings
Set as Default: Star a template to use it automatically for new interviewers
Delete: Remove templates you no longer need
Template Codes
Each template gets a unique code (e.g., ABC123) that you can copy and share with teammates. Click the code badge to copy it to your clipboard.
Why this matters:
Templates save time when hiring for similar roles repeatedly. Instead of configuring each interviewer from scratch, apply a template and make minor adjustments.
Interview Evaluation
This section controls how the AI scores and evaluates candidate language proficiency.
Language Proficiency Templates
Create evaluation templates for different languages:
English, Spanish, French, Portuguese, Japanese, Arabic
Each language can have multiple templates (e.g., "Customer Service" vs "Technical Roles"), and you can set one as active per language.
Creating and Managing Templates
New Template: Click "New Template" to create a custom rubric
Set Active: Choose which template to use for interviews in that language
Edit: Click a template to customize its scoring criteria
Scoring Rubric
Each template defines what scores 1–5 mean for categories like:
Grammar
Vocabulary
Clarity
Conversational flow
Expand a category to edit the criteria for each score level.
AI Tune
Use the AI Tune button on any category to adjust scoring criteria with natural language:
Example: "Make scoring more lenient for entry-level roles"
The AI will rewrite the score definitions based on your instruction.
Why this matters:
Standardized evaluation prevents subjective scoring and keeps hiring fair, especially when multiple recruiters review results.
Interview Integrity
This section controls interview trust, fraud prevention, and cheat detection rules.
Enable Cheat Detection
Toggle cheat detection on or off for all interviews in your workspace. When enabled, the AI monitors for suspicious behaviors during interviews.
Detection Threshold
Set the sensitivity level from 0 (less sensitive) to 100 (more sensitive).
Lower values = fewer flags, may miss some issues
Higher values = more flags, may catch false positives
Detection Types
Select which behaviors to monitor:
Facial Behaviour: Unusual eye movements or looking away frequently
Multiple People: More than one person visible on camera
Phone Detection: Candidate using a phone during the interview
AI/Scripted Answer: Responses that appear pre-written or AI-generated
Unusual Delays: Long pauses that may indicate looking up answers
Tab Switching: Candidate switching browser tabs during the interview
Use "Select All" or "Deselect All" to quickly toggle all detection types.
Why this matters:
Integrity settings protect interview quality and give recruiters confidence in candidate results, especially for remote or high-stakes roles.
Agent Library
This section lets you browse and preview the AI agent personas (mascots) available for your interviewers.
What are Mascots?
Mascots are the visual and personality representations of your AI interviewers. Each mascot has:
A unique name and appearance
A distinct personality and communication style
A specific role in the recruitment process
Examples include Milo (the main interviewer), Sally (the sourcer), and Chloe (the receptionist).
Using the Agent Library
Browse available mascots and their descriptions
Preview how each mascot looks and communicates
Select mascots when creating new interviewers
Why this matters:
Choosing the right mascot helps create a consistent and branded candidate experience that aligns with your company culture.
Languages & Voices
This section shows all available languages and voice options for your AI interviewers.
Voices are powered by LMNT and Cartesia.
Use Browse Voice Providers to filter by provider, search by name, preview with the play button, and add voices to your workspace; those voices then appear in the voice dropdown when you create or edit an interviewer.
Available Languages
HeyMilo supports interviews in multiple languages including:
English (US, UK, Australia, and more)
Spanish
French
And many other languages
Each language has multiple voice options to choose from.
Previewing Voices
Search by language, country, or voice name
Click the play button to hear voice samples
Compare different voices before selecting one for your interviewer
Why this matters:
Selecting the right language and voice ensures candidates can interview in their preferred language and creates a more natural, comfortable experience.
Best Practices for AI Tuning
Keep Company Context concise — just enough for the AI to represent your brand
Add key information to your Knowledge Base so it's available across all interviewers
Create Interview Templates for roles you hire repeatedly to save setup time
Use AI Tune in Evaluation to customize scoring criteria with natural language
Enable Cheat Detection for high-volume or skills-based interviews
Preview voices in Languages & Voices before selecting one for your brand
Treat AI Tuning as your foundation — interviewers inherit these defaults automatically
