Their tool "pgr" is a research preview only, so it'd be interesting to see semble vs pgr.
I'm also collecting other tools that are similar, most notably is probably Morph's WarpGrep (has a free tier too). Apart from that, there is codemogger (https://github.com/glommer/codemogger), cs (the author also commented in this HN post).
In the similar area, but not fully related, the author of fff is also pretty involved in any thread that goes into that direction (see e.g. https://x.com/neogoose_btw/status/2052161471296225710). Similar to colGREP is also mgrep (by mixedbread) and osgrep (but they seem to predate colGREP). I also found codedb on X (https://codegraff.com/blog/codedb-code-intelligence), the post reads well, but haven't tried.
