The video you need might be gone by tomorrow. The document will be quietly edited. The account will be suspended. Your best sources are often the ones that aren't there when you come back.

Classified is the research notebook for people who've noticed.

01 · Save

Before the original is removed.

From TikTok, Instagram, YouTube, or X — tap Share → Classified. The video saves to your iPhone immediately, with source URL, creator handle, and timestamp attached. Independent of platform moderation, account deletion, or regional blocks.

01
02 · Organize

Cases, arguments, evidence.

Structure your research around the question you're actually trying to answer. Each case holds arguments; each argument holds supporting evidence. Rate every source Strong, Interesting, or Weak — so you always see where your case is solid and where it isn't.

02
03 · Present

Show your work, not your camera roll.

Full-screen Present mode swipes through your arguments one at a time, playing saved videos inline. For when the conversation actually happens — with a friend, on a podcast, or just to yourself, to see if the case still holds up.

03

For researchers. Of whatever kind.
