LensQuest

Four people saw the same thing from four places — so their stories don’t all match. Reading across them is a rule, not a vibe.

Four accounts, one event — how to read across them

Nobody in LensQuest is lying. Each narrator simply stood somewhere different, so each one saw a slice. To find what actually happened you don’t pick the loudest story — you weigh the accounts by one rule.

  • 🤝 Agree. Two people who could both see it say the same thing — that’s corroboration, the strongest evidence you can get.
  • ⚔️ Can’t both be true. Two people claim different values for the same detail — at most one is right, so the detail is in dispute.
  • 🙈 Couldn’t see. A narrator claims something they had no view of — that’s a guess, not evidence, even if it happens to be right.
  • 🧩 The fifth account. Drop the guesses; keep what two real witnesses agree on. That settled set is what we can actually conclude.

Everything runs on your device — no internet, no accounts, no AI grading your answer.

Meet the crew — four ways of seeing

  • Ravi stood at the window bench, facing the window and the coat hooks — a clear view of who opened the window and the colour of the coat.
  • Mei was by the coat hooks near the side door, her back to the window — she saw the coat and which door everyone left by.
  • Sam watched from the hall doorway — he saw the door and heard the crash, but the coat was too far to make out.
  • Nella was painting in the far corner, facing the wall — she could only hear the hall, so everything else she says is a guess.
  • Lens is the calm reader who never asks “who’s telling the truth?” — only “who could actually see it, and do they agree?”
