Most people don't lose arguments because they're wrong. They lose because the right sentence arrives ten minutes late — in the car, in the shower, at 2am. LensByNEAR exists to close that gap.
Why we built it
Every other AI tool assumes you can stop and type. A live argument gives you no such pause. So we built for the one constraint that actually matters — the four seconds after your opponent stops talking.
What we won't do
Vector is locked to your side, but never to a lie. It will not invent a statistic, a source, or a fallacy to hand you a win. If the other person is simply right, it tells you — and finds you the strongest honest angle instead.
Where it's going
The long game isn't faster answers, it's memory: a coach that knows how you argue, how your opponents argue, and what beat you last time. Every debate you run makes the next one sharper.
Questions, answered
How does Vector know who's talking?
You stay in control: hold Q (or the Opponent button on your phone) while the other person talks, and tap any transcript line to fix a mislabel. No unreliable auto-guessing.
Will it make things up to win?
No. Vector is side-locked to you, but honesty-locked too — it never invents statistics, sources, or fallacies. If your opponent is simply right, the fact-check says so and Vector finds you the strongest honest angle instead.
Does it work on my phone?
Yes — the debate room is built like an app: bottom tabs, big controls, one hand. Keep the screen on while listening; browsers pause microphones in background tabs.
What's opponent intel?
Paste a YouTube video or channel (or a TikTok/Instagram link) and Vector reads the transcripts, researches the person, and builds a dossier — their positions, style, likely arguments, and real quotes.
Is my audio stored?
No. Audio is transcribed and discarded. Your debates are saved as text to your account so they follow you across devices, and you can delete them anytime.
What do the tiers actually change?
Each tier runs a different AI. Cora is fast and capable, Valen reasons deeper and unlocks opponent intel, Vector is the flagship with unlimited intel, opponent profiles, and priority speed.
