Polis-Inventory maps the ancient Greek settlements from the Archaic and Classical periods (c. 650–325 BCE) as identified in the pioneering work published by the Copenhagen Polis Centre, An Inventory of Archaic and Classical Poleis by M. H. Hansen and T. Nielsen (Oxford, 2005; here referred to as the “HN Inventory”). The digital dataset in Polis-Inventory, based on the HN Inventory, comes primarily from the website polis.stanford.edu, managed by Stanford University’s Department of Classics. The dataset reflects ongoing digitization and enhancement of the original print work by the Stanford team and subsequent classical scholars. We continue to advance the data, improving locations and correcting errors as they are encountered. Polis-Inventory is an informative, interactive companion to the HN Inventory, allowing visualization, search, and filtering of the poleis using a set of physical and historical parameters. Parameter definitions are available in context as you browse. Further detail and attribution can be found at odysseymaps.io, polis.stanford.edu, and in the HN Inventory itself. If you would like a copy of the data in this app, you can copy it to your clipboard in GeoJSON format from the About page. Privacy: No user data is tracked or stored by Polis-Inventory. Support: An optional Tip Jar is available to support ongoing development (tips are voluntary and don’t unlock features). Independence: Polis-Inventory is an independent companion and is not affiliated with, sponsored, or endorsed by Stanford University or Oxford University Press.

Outputly — The Output Training System for Language Learning You've studied. You understand more than you can say. Outputly is the missing piece — the output training system that transforms passive knowledge into real conversation. This is the companion app for your Outputly subscription. Continue your course on your phone, stream lyric videos, download for offline practice, and pick up exactly where you left off on the web. Why songs? 90% of people experience "earworms" weekly. When a phrase plays in your head on repeat, you're not just remembering it — you're mentally rehearsing speech. Music builds procedural memory: the same system that lets you ride a bike without thinking. What's inside: • Stream lyric-video lessons with synced native and English text • Audio-only mode for commutes, walks, and workouts • Download any album for offline play • Guided Learn Mode with prompts and responses • Progress that syncs automatically with outputly.io • Lock-screen controls and AirPlay The Progressive Song System: Every song builds from 4 core phrases into 30+ practical chunks. Across each 100-song course, that's 400 foundations that generate 3,000+ real phrases — the 95% you need to start having real conversations. Lifestyle companion albums — Walking Companion, Workout edition, and more — let you absorb the language passively during everyday activities. Available now: Spanish. More languages coming soon. Who it's for: • False beginners who've studied for years but freeze up • Heritage speakers who understand family but reply in English • Input-method users (Duolingo, comprehensible-input podcasts, immersion) ready to activate passive knowledge • Anyone who understands but can't speak How it works: Sign up and subscribe on outputly.io. Then sign in here to continue anywhere — phone, tablet, car. Your progress, favourites, and downloads stay in sync. The language you've been learning is already in your head. Outputly gets it out of your mouth. — Support: hello@outputly.io Terms & Privacy: outputly.io/terms
