Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
A privacy-first browser toolkit with 100+ PDF, image, developer and AI utilities
PDF, image, developer, finance, business, text and AI utilities share a single interface instead of living across separate sites.
Files are handled on the device rather than uploaded, which suits sensitive contracts, IDs, invoices and internal documents.
Merge, split, rotate, number pages, compress, and convert between JPG and PDF without installing a desktop PDF editor.
JSON, XML and SQL formatting, JWT decoding, hashing, Base64 and URL encoding, minifiers, regex testing and Markdown preview.
