Our Technology
Apollo: A Language Built for Power and Precision
Uncompromising Innovation. Apollo was crafted from the ground up to deliver advanced language features without shortcuts. Its bytecode stack-based VM makes design and debugging effortless. Crave speed? Flip on LLVM-based JIT for blazing performance across all platforms.
Morpheus: The Heartbeat of Your System
Forged by Legends. Inspired by Bell Labs’ Inferno and Plan 9, Morpheus blends old school MUD ingenuity with modern engineering. This robust framework powers rule engineering and analysis for interactive fiction and visual novels with unmatched flexibility and nostalgia-fueled charm.
Prometheus: Craft Interactive Fiction Like Never Before
Write Stories That Live. Prometheus is your all-in-one IDE for interactive fiction and visual novels, featuring first-class mapping, a stellar code editor, and a built-in runtime console. Bring your branching narratives and immersive worlds to life with ease.
Alcibiades: Command-Line Power, Your Way
CLI Done Right. Love the terminal? Alcibiades lets you harness our entire ecosystem without a GUI. Write Apollo in your favorite editor, add JSON metadata, and run, test, or deploy with a single command.
Combinatory Categorial Grammar: Next-Gen Parsing
Parse Smarter, Not Harder. Our built-in CCG module brings cutting-edge natural language parsing to Apollo. Say goodbye to clunky traditional libraries—focus on creating, not wrestling with code.
Seamless Deployment: Web, Mobile, and Standalone
One Click, Everywhere. Deploy your creative efforts in interactive fiction and visual novels effortlessly to web, iOS, Android, or standalone apps. With full Unicode support, rich text formatting, and ncurses-based control, your stories shine on any device with zero hassle.
Frequently Asked Questions
What is interactive fiction?
Remember those "choose your own adventure" books? Interactive Fiction (IF) is the digital version of that, but with a lot more freedom. You're the main character in a story, but instead of just picking from a few options, you type what you want to do, like "examine the strange glowing mushroom" or "ask the robot about its past." It's a video game that's all about the story. Your choices genuinely change how things play out, leading to different branches of the plot and multiple endings. While some modern IF has graphics and sound, many classic and new titles are text-based, focusing on pulling you in with a great narrative, much like a good book. If you've ever enjoyed story-heavy RPGs or point-and-click adventures, you'll feel right at home.
When will Mythoi products be available?
We’re gearing up for a late Q3 2025 beta. Stay tuned for more dates—join our newsletter for the latest!
What runtime environments does the Mythoi platform support?
Run interactive fiction and visual novels on macOS, Windows, Linux, and FreeBSD with standalone apps supporting text, graphics, and audio. Deploy to the web with an Apollo Codex for instant, no-install storytelling. iOS and Android deliver seamless mobile experiences. An ncurses module for retro terminal vibes is coming soon.
Is Mythoi Z-Machine compatible?
Not anymore. Early builds supported Z-Machine output, but feedback showed fans of classic tools prefer open-source options. We’re focused on propelling interactive fiction forward with a modern, high-performance runtime built for today’s stories.
Do I need to use Prometheus to work with Apollo?
Nope! Prometheus is our tailored IDE for crafting interactive fiction and visual novels, with stellar mapping and editing tools. Prefer the terminal? Use Alcibiades for command-line workflows and import your Codex into Prometheus anytime for mapping support.
What documentation will Apollo offer?
Expect a full EBNF/PEG grammar, detailed API docs, and comprehensive written and video tutorials. We’re also including a PDF with Apollo insights to supercharge AI-assisted coding, so you can focus on creating, not decoding.
Is Apollo a general-purpose language?
Yes, Apollo is a general-purpose language with a prototype-based design, packed with modern features like built-in concurrency and no manual memory management. But its runtime is laser-focused on interactive fiction, visual novels, rule-testing, and simulations.
For TTRPG, CRPG, or JRPG designers, Apollo slashes playtesting time—build immersive stories, combat systems, or NPCs in hours, not days. Tweak rules instantly with lambda constructs and see results fast.
While Apollo can handle broader use cases, our runtime is optimized for these creative goals. Curious about what’s next? Join our newsletter for a peek at our roadmap!
Why a GP Language? Why not a DSL?
Why go GP? Apollo’s general-purpose core, with its prototype-based architecture, can morph into a domain-specific language via a front-end lexer and parser pipeline. Tokenize, build an AST, apply semantic analysis, and boom—you’ve got a DSL tailored for interactive fiction without sacrificing flexibility. Better yet, we’re crafting converters to port Inform’s natural language stories seamlessly. Apollo’s power lets you break free from niche limits, blending computational might with narrative magic. Join our newsletter to stay in the loop!
Isn’t this overkill for interactive fiction?
Maybe a bit! Apollo and Morpheus are built for interactive fiction and visual novels but also support advanced rule engineering and simulations down the line. These genres are our sandbox—a perfect starting point for crafting immersive, rule-driven stories with MUD-inspired flair.
Are you all mad?
as hatters.
What is your future roadmap?
We’re supercharging our runtime and API to deliver advanced 2D graphics, building on our existing shader and graphics support. Think Flash-like functionality—smooth rendering pipelines, GPU-accelerated visuals, zero bloat, and none of the headaches. Your interactive fiction and visual novels will dazzle like never before.
