Projects
Tools, products, and research.
Everything Callisto is building in one place — from live utilities to experiments still taking shape.
01 Tools
Small tools for small problems — fast, focused, and deliberately simple.
TOOL [Coming Soon]
PDF Kit
Clean, crop, merge and extract pages without opening a bloated editor.
UTILITY [Coming Soon]
JSON Lens
Inspect, format and diff JSON with a calm, keyboard-first interface.
UTILITY [Coming Soon]
Table Forge
Turn messy tabular data into something you can actually work with.
02 Products
Larger products built around workflows rather than single tasks.
PRODUCT [Coming Soon]
Callisto Cookbook
Save, organize and cook from recipes without the noise of a social feed.
PRODUCT [Coming Soon]
Favorites Hub
A quiet place to collect links, references and saved fragments — then actually use them.
03 Research
A quieter layer of the system — questions that don't have obvious answers yet.
Behavioral Index
A research-driven system for analyzing video and indexing observable behavioral patterns using the Big Five / OCEAN framework. Experimental, not a verdict.
