Keep control if control is the point
Chub's prompt settings, lorebooks and branches are meaningful tools for authors. If tuning those tools is part of your enjoyment, a call-oriented companion is a different choice, not an automatic upgrade.

Documentation comparison · Reviewed October 18, 2026
A Chub AI alternative should be clear about what you trade away: Chub documents model connections, prompt controls, lorebooks, branching chats and export tools. It also offers an integrated Mars subscription, so bringing your own API key is not mandatory. Prelulu is worth comparing when you want character text conversations and live calls without choosing a model provider, rather than another configurable roleplay workbench.
Definition
Chub is a configurable character-chat environment with model connections, story branches and portable chat data. Prelulu's comparison angle is a character conversation that can become a live voice or supported-avatar video call, not equivalent control over model APIs. This page is published by Prelulu using documentation reviewed October 18, 2026, without testing model quality or treating older documentation as a guarantee of current operation.

Chub's prompt settings, lorebooks and branches are meaningful tools for authors. If tuning those tools is part of your enjoyment, a call-oriented companion is a different choice, not an automatic upgrade.
Prelulu does not ask you to select an external model API for ordinary conversations. Chub's integrated Mars plan also avoids key management, so convenience alone is not an exclusive Prelulu feature.
Chub documents text-to-speech. Prelulu offers credit-based live voice and supported-character avatar video, with your camera off until enabled. Daily free text lets you try the character before a call.

Bring the trope and character type you loved. The story starts the second you open a chat.

His wolf chose you. The alpha still won't admit it. The forest holds its breath as you navigate the moonlit path, a sudden stillness preceding the snap of a twig behind you. You turn, and his eyes, like molten gold, lock onto yours, an ancient recognition sparking between you that transcends mere sight.

Mafia Kingpin. Ruthless Heir. Your dangerous husband. Dante Marchetti inherited an empire built on fear, but the only thing he cannot control is losing you. You have been married to him for three months, long enough to realize something strange: the man everyone fears seems to have an impossible amount of patience for you. The ruthless heir who never bends for anyone somehow tolerates your questions, your stubbornness, and even your challenges to him. And you cannot understand why.

Seraphina Vane is an ancient vampire countess who has outlived empires, admirers, and every distraction worth having. For centuries, nothing has held her attention for long. Then you arrived, and somehow, the woman accustomed to taking what she wants finds herself wanting something she cannot simply take: your choice. From her throne-like chair at the edge of the shadowed ballroom, she watches you approach, one hand resting lazily around an untouched glass of wine. “So. You are the reason everyone has been telling me I look less bored.”

A fae prince searched centuries for one face: yours. Immortal and endlessly patient, he has waited lifetimes for this meeting. You arrive startled; he looks at you as if he already knows you. You stumble through the veil into an ancient, silvered glade, the air thrumming with untold power. Before you stands a being of impossible grace, his gaze, the weight of centuries, settling upon your startled face as if recognizing a long-lost dream.

The Underworld's king bows to no one but you. The air around him thrums with the weight of ancient power, a stillness that precedes a storm. You stand before Azrael Kaine, the fearsome King of the Underworld, his gaze a slow, dangerous burn that seems to pierce through your very soul. Every other creature in his court cowers, but his focus remains solely, undeniably on you.

Your arranged fiancé secretly wants you to choose him. Your marriage was arranged to mend two ancient houses, and the eldest son was raised never to mind where the bloodline sends him. Yet you find him on the rain-dark terrace the night before the vows, turning the family signet over and over like he's deciding whether it fits. He doesn't startle when he hears you, he just smiles, rueful, as if you've caught him mid-confession.

The lethal assassin only lowers her guard for you. The underworld knows why to fear her blade. You're about to find out firsthand. Rain. A dead-end alley. A shadow peels off the brickwork, a woman who moves like a blade already drawn. Her gaze pins you to the wall. You don't run. That's either the bravest thing you've ever done, or the stupidest. She hasn't decided yet.

The untouchable CEO loses his composure under your touch. The sterile glow of the executive lounge reflects off your polished shoes as you step inside, a hush falling. All eyes drift to the figure by the panoramic window, his profile as sharp and unyielding as the city skyline he oversees. He turns, and for a fleeting moment, his gaze, usually a fortress, seems to hold an unexpected tremor just for you.
FAQ
Not always. Chub's documentation describes Mars as an integrated subscription without key or server management. External provider connections are another option, with their own setup and costs.
Its Just Chatting guide explicitly documents text-to-speech. That should not be confused with live voice or avatar video calls, which were not documented in sources reviewed October 18, 2026.
The reviewed documentation describes a subscriber-hosted beta others can join, but does not establish live avatar video calling. The feature name alone is not evidence of a camera or video-call mode.
Your Chub chat history does not come over, but the character can. On the web, upload its character card (.json or .png), paste its description or a link, or upload a screenshot, then review the draft before saving. Recap the details that matter in your first message if you want the story to pick up where it left off.
