Writing & editing tools
Move from a rough idea to a clean draft. Count what matters, fix the casing, preview the structure and make room for a focused writing session.
Find your starting point.
A tool is more useful when you know the next step. These collections connect the task, the tool and the explanation.
Data conversion & developer tools
Convert a representation without losing the meaning. These small utilities cover text encodings, spreadsheet rows, identifiers and timestamps without sending your input to a server.
Privacy & everyday security tools
Generate locally, verify deliberately and understand what a tool can prove. A random password, an identifier and a file checksum solve different problems.
Design, image sizing & accessible color
Make images fit and text stay readable. Work through shape, pixel density and contrast as separate decisions before exporting a final asset.
Reading goals, book discovery & tracking
Find a book you want to open, then make a reading plan that fits your week. Browse public catalogs, measure a comfortable pace and keep your shelf in your own browser.
Home lab, network & server planning
Measure the equipment you own before sizing the equipment you might buy. Plan rack space, power, backup time and Wi-Fi coverage with visible assumptions.
Camper van & off-grid power planning
Separate energy used over a day from power used at one moment. A useful first plan makes loads, runtime and conversion losses visible before any equipment is selected.
Creative projects, layouts & practical planners
Try the layout before cutting material, packing a board or arranging a room. Keep measurements in consistent units and use a first draft to surface constraints.
