When you create a show with the wizard, Mato matches and assigns one or two hosts automatically. This guide covers reviewing those hosts on the show's Hosts & voices page, swapping them for different talent, and adjusting voice and delivery on a host's own profile.
Talent is its own place in the sidebar
Every AI host you use lives in your workspace's talent roster, independent of any one show. Click Talent in the sidebar to see every host you've created or forked. On air groups the hosts on each show, with Hear them together to play them as a pair. All talent lists every host with its portrait, type, show, and voice, and you can search, filter by type or voice, and sort the list.

From here you can:
- New talent to start a new host from scratch, guided by a short wizard. Describe the personality in a sentence or two (10 to 2,000 characters) and Mato generates the rest of the profile: traits, bio, and sample dialogue.
- Browse templates to fork a pre-built profile into your workspace instead of starting blank.
A host you create here is not attached to any show until you assign it, which happens from the show's settings.
Review and assign hosts on a show
Open your podcast and click Hosts & voices under Configure in the show's sidebar.

Each row shows the host's name, a badge marking the lead host (Host · speaks first) or Co-host, then their type and pace, for example "Fictional · rapid pace". The voice is set on the talent, not here. When a host has a voice sample, a Sample button on the row plays it without leaving the page.
A show can have up to two hosts, and the first host opens every episode. To add one, click Add a host, search your talent roster, and pick a name. With two hosts already assigned, Add a host stays unavailable until you remove one. The assignment applies immediately, no separate save step. If your roster is empty, the dialog links straight to Create a talent.
To remove a host, open the row's menu and choose Remove from hosts. This runs right away with an undo option in case you change your mind, and frees the slot for another host.
The ··· menu on each row also has Open talent, which takes you to that host's full profile, where voice and personality actually live.
Customize voice and delivery
Voice settings belong to the talent profile itself, not to any one show, so a change applies everywhere that host is assigned. Open a host from Talent, or through Open talent on its row in Hosts & voices, and find the Voice card. It shows the current voice, a few Audition clips, and the delivery settings.

Click Change voice to open Voice studio. It offers three ways to give the host a voice: Pick a preset (each preset has a play button so you can hear it first), Clone a real voice, or Design one from scratch. Click Done to go back to the talent page. See Give a host a voice for each route.
The Voice card also shows the host's delivery settings under Delivery:
- Accent is a regional accent, such as General American.
- Speech speed controls pacing: Slow, Normal, Fast, or Very fast.
- Audio profile is a free-text description of how the host should sound in the mix.
- Director notes is a free-text field for direction on tone, pacing, and delivery beyond the audio profile.
Listen to the host under Audition on the Voice card.
Edit host personality
The same profile page shows the host's personality, which shapes how Mato writes dialogue for that host: a written narrative and a grid of characteristics. Five personality scores (Improvise, Explorer, Humor, Formal, Technical) show on the host's card in the Talent roster.
Click Edit talent to change the narrative, traits, or other fields, then click Save changes. Personality changes affect scripts written after the change; episodes already generated keep the dialogue they were written with.
What to do next
Your hosts are set. Next:
- Add content sources. Connect RSS feeds so Mato has material to draw from.
- Generate and edit your first episode.
