The video essay's occupational hazard is the confident claim. Your script says "experts believe X" or "as the CEO admitted in an interview" — and the moment it publishes, the comment section becomes a peer review you didn't sign up for. One misattributed quote, one "source?" you can't answer, and the video's credibility — and the channel's — takes the hit. Corrections pinned in comments are the genre's walk of shame.

The alternative — real sourcing — traditionally costs what academics pay: days chasing down where claims come from. For creators on a schedule, the temptation is to sand the claims vaguer ("some say...") until they're defensible because they're empty. There's a third option now: research that arrives pre-cited.

deep_query is a research assistant whose every claim comes with a receipt: ask your script's factual questions and the answers arrive grounded in real videos with inline timestamp citations — who said it, where, at which second. The "according to" moments in your script stop being paraphrases from memory and become checkable references.

It handles the essay genre's whole research stack: establishing what experts actually say (with the disagreement mapped, which often is the essay), finding the primary quote instead of the secondhand version, and pressure-testing your thesis's load-bearing claims before the comment section does. Your description box gets a source list; your pinned comment stops being a correction.
