Query: Holographic correlators in AdS$_3$ without Witten diagrams   We present a formula for the holographic 4-point correlators in AdS$_3 \times
S^3$ involving four single-trace operators of dimension $k, k, l, l$. As an
input we use the supergravity results for the Heavy-Heavy-Light-Light
correlators that can be derived by studying the linear fluctuations around
known asymptotically AdS$_3 \times S^3$ geometries. When the operators of
dimension $k$ and $l$ are in the same multiplet there are contributions due to
the exchange of single-trace operators in the $t$ and $u$ channels, which are
not captured by the approach mentioned above. However by rewriting the
$s$-channel results in Mellin space we obtain a compact expression for the
$s$-channel contribution that makes it possible to conjecture a formula for the
complete result. We discuss some consistency checks that our proposal meets.
