About Demades

Demades is the map of every history podcast. Spin a 3D globe, scrub a timeline from the ancient world to today, and click a place and a year to find the people, events and episodes that belong there. Try it now at demades.ai/history — it runs in your browser, with no sign-up.

Demades is operated by D3SMC LLC (d/b/a Demades), Austin, Texas.

What the product does

• Explore history on the globe. Borders change as you move through time, and the people and events of each age are pinned where they happened. Every person, event and territory has its own link you can share.
• Find episodes about it. Each place and moment links to episodes about it. Real shows are credited and linked back to their creators.
• Ask the globe. A built-in assistant answers questions about what you are looking at and moves the globe for you. It is AI, and it says so.
• Fill the gaps with AI episodes, clearly labelled. Where no episode exists yet, Demades can make one: it researches the subject, writes a multi-host script and voices it with synthetic voices. Every AI-made episode is labelled as AI and ends with a spoken AI disclosure.
• Listen anywhere. Episodes stream in the browser and in the Demades app; no install or account is needed to explore or listen.
• Clip and share. Episodes can be cut into short, captioned vertical videos for TikTok, Reels and Shorts.
• Publish — only with your permission, only after you approve. If you connect a social account, Demades can post an approved clip to it on your behalf. Nothing is ever posted without an explicit human approval step.

How the TikTok integration works

Demades integrates TikTok Login Kit and the Content Posting API so a creator can publish Demades clips to their own TikTok profile:

• Sign in with TikTok (Login Kit, scope `user.info.basic`). You authorize Demades from TikTok's own consent screen. We read your `open_id` and display name only — enough to confirm which account a clip will post to. We never see your password.
• Upload as a draft (Content Posting API, scope `video.upload`). With your authorization, Demades sends an approved MP4 to your TikTok inbox as a draft, via TikTok's `/v2/post/publish/inbox/video/init/` endpoint. You finish and publish it inside the TikTok app.
• Direct Post (Content Posting API, scope `video.publish`). Optionally, you can let Demades post a clip directly to your profile at a privacy level you choose, via `/v2/post/publish/video/init/`.

Every post is human-approved before it is sent. A clip moves through an internal review queue and is published only after a person approves it. You can disconnect your TikTok account at any time, which revokes Demades' access.

Your data and your control

We request the minimum scopes needed for the features above and store only what's required to operate them (your TikTok `open_id`, display name, and the authorization tokens). We do not sell your data. See our Privacy Policy for the full detail, our Terms of Service for the agreement, and our Editorial & AI policy for how we handle AI-generated content and corrections.
