Playgrounds.

A hosted web app that positions MENA political actors (parties, politicians) and texts (manifestos, speeches, articles, bills, user-pasted prose) on a political compass, with a regional map view and methodology-transparent reasoning. Built for researchers and academics — the methodology is the product, not a footnote.

A free Spanish course from A2 to B2, in the Spanish they speak in Madrid. You read with tap-to-translate, listen, take dictation and write, and the words you meet come back for review. No streaks and no account; your progress stays in your browser.

Free tools for research in and on Arabic: repair Arabic copied from a PDF, romanize names and titles by ALA-LC, IJMES or DIN 31635, cite Arabic sources in APA, Chicago or the ACRPS style, check a quotation against its source, look references up in public catalogues, convert Hijri dates, and see how social-science terms are rendered in Arabic. Every result says where it came from, and the text you paste stays in your browser, apart from the catalogue lookups you ask for.

Identify musical instruments by ear. Over a hundred instruments in ten families, every clip loudness-matched so you compare the sound and not the volume; a few questions to narrow it down when you're not sure; and a compare mode for your own recording, which never leaves your browser. Free, MIT-licensed, and it works offline.

Identify everyday sounds by ear: a cough or a throat clear, rain or applause, a drill or a blender. Real recordings in nine families, each also heard under speech, far away and through a phone, with a word finder, a quiz and a compare mode for your own recordings. Free, MIT-licensed, and it works offline. A sibling of Instrumedia.
