Marinara-Engine (QMultimedia-Q6)

A local, AI-powered chat, roleplay, and game engine built around one idea: you install it, you run it, and it just works. Oh, and don’t forget about the part where you have fun! ALSO, HEY, LOOK, IT’S FREE.
Created with agentic use in mind, allowing multiple requests at once. Everything is connected. Chat with your characters OOC about your roleplays. Have them create RP scenes for you. All designed with simplicity in mind: we don’t want to spend hours on setup, we just want to play.

This package requires QMultimedia-Q6 to runs (should also detect the presence of GPU if not fall back to CPU, i cannot test it)

Three chat modes — Conversation (Discord-style DMs), Roleplay (immersive RPG with sprites and backgrounds), and Game (AI Game Master with party, quests, and combat). Characters can share memory across modes. Create or import characters, search the multi-site Card Browser (Chub.ai, JannyAI, CharacterTavern, Pygmalion, Wyvern, and more), organize chats into folders, branch conversations, swipe between alternate responses, and import from SillyTavern.

Character expression sprites with automatic emotion switching, custom scene backgrounds, dynamic weather overlays, gallery illustrations, short scene videos from generated illustrations, Game Mode storyboards, inline Roleplay storyboard episodes with selectable prompt layers, two visual themes (Y2K Marinara and SillyTavern classic), and light/dark mode.

An optional one-click catalog of 33 first-party agents and feature packages. Fresh installs stay lightweight with no bundled agents. Open Agents → Download Agents to install only what you want or uninstall packages you no longer need. When a compatible update appears, Marinara asks before downloading it. Choosing No keeps the installed version and leaves Update available in Download Agents for later; installed packages also remain available while the server is offline. Existing installations retain their agents during Engine upgrades. Stable Engine builds use the released Agent catalog, while git installations on the Engine staging update channel automatically use the matching Marinara-Agents staging catalog and artifacts for testing. Package sources, artifacts, and the complete catalog are published in Pasta-Devs/Marinara-Agents. You can also create custom Agents. External Agent imports require the Allow custom Agent imports Danger Zone toggle and an explicit capability review; official downloads and Agents you create yourself are unaffected.

• Writer Agents: Prose Guardian, Continuity Checker, Narrative Director, Knowledge Retrieval, Knowledge Router, and Card Evolution Auditor.
• Tracker Agents: World State, Expression Engine, Quest Tracker, Background, Character Tracker, Persona Stats, Custom Tracker, Inventory Tracker, and World Maps.
• Misc Agents: Echo Chamber, Noodle, Illustrator, Lorebook Keeper, Long-Term Memory, Combat, Immersive HTML, Music DJ, Haptic Feedback, CYOA Choices, Storyboard, Calls, UNO, Chess, Poker, 8-Ball Pool, Tic-Tac-Toe, and Rock-Paper-Scissors.

See the Downloadable Agents Reference for modes, behavior, and setup guidance for every package, or browse the official Agent repository directly.

Preset system with drag-and-drop prompt ordering, lorebooks with keyword triggers, an AI lorebook maker, world info inspector, regex scripts, and a macro/template system.

Personal Extensions are disabled-by-default drafts authored for you by Professor Mari. Every executable change invalidates approval, and only the exact reviewed SHA-256 fingerprint can run inside Marinara’s restricted browser or OS sandbox. Third-party imports stay hidden until the host and user deliberately open both External Extensions safety gates. Legacy tools can request separately disclosed Full page access for DOM compatibility, but that mode is deliberately unsandboxed and should be enabled only for exact code you trust. See the Personal Extensions guide.
