A Complete Publishing Solution Without the SaaS Subscription
We did a complete clean-sheet design and implemented the features you want. Automatic AI "Continuity Engine" chapter goals, complete privacy (it runs entirely on your Mac or PC), a perpetual license, and no training someone else's LLMs. Plotters and Pantsers rejoice: complete bi-directionality of text-to-timeline, and timeline-to-text creation and revisions. Forget the expensive spreadsheets and post-it note type timeline add-on software. This is the flowing, changing and intuitive timeline tool bundled with a complete authoring suite.
Writing Sessions You'll Look Forward To
A comfortable, responsive editor with chapter outlines, immediate access to your research, event goals, dictionary and thesaurus without leaving the page. Commit your changes, and watch the timeline take shape following your story. Dark mode/light mode over the entire application, auto-save and checkpoint protection guards your ideas through its evolution.
A Rich Character Environment
A developed character is the result of a deep profile, and helpful tools like a character's personal timeline complete with chronological associations with other characters.
Your Research at Your Fingertips
Import, write or export your research just like your manuscript. You're never locked in to any service or product with Codex Reactor. Enter your lore in your Research binder, or access it in a flyout view in the Manuscript Editor. Edits are saved automatically, like nearly everything else.
Use AI for Its Strengths, Not for Replacing Your Style
the Continuity Engine checks story mileposts, becomes a Lore Master of your Universe, creates manuscript elements like separators and chapters, streamlines your imports, separates front and back matter, and generally makes your writing primed for creation.What Codex Reactor does not do is write your copy.The current development engine is a Llama 3 8B language model. Made for local installation and use, the Llama family is meant to put as small a footprint on your system as possible. There are faster AI engines, but in order to deliver the promises of privacy, security and the freedom from SaaS storage, processing, and subscription fees, the quantized and minimized Continuity Engine is the future of desktop software intelligence.
