Why we cite every answer.

Engineering · Deepgrip

Karthik leads retrieval at Deepgrip — vector indexing, ranking, and the architecture decisions behind sub-second search across decade-deep archives. Priya leads evaluation at Deepgrip — citation correctness, retrieval recall, and the methodology behind every claim the system is allowed to make.

Every answer Deepgrip returns must point to a specific moment in a specific file. No exceptions, no 'as a language model.'

In consumer chat, hallucination is annoying. In production media, it is catastrophic. If a producer writes copy off a quote that was invented, the on-air talent reads it, and the lawyer for the person it was attributed to picks up the phone. We built Deepgrip such that the system cannot answer without showing its work.

Trust isn't built by being clever. It is built by showing your work.

Once citation is mandatory, a lot of other things become easier. Click any sentence in an answer, jump to the second in the video where it was said. Export with cited timestamps, drop it into your edit. None of those features are possible if the system is allowed to wing it.

Our customers are not making sonnets. They are making claims that go out to millions of people. The question they need answered is not "is this clever" but "is this true." For that question, the only honest answer is to point at the source.

If we ever drop citation to chase a faster benchmark, please tell us. It would mean we lost the plot.
