Found inside by my daughter.

Moved from Entelegynes.

From our local expert-->
Rod Crawford says:

"I have to agree with Mandy on this one. Probably C.mildei. Besides the
minimal carapace groove, it doesn't have the hair tuft on the front
end of the abdomen that's found in most Clubiona."

I contemplated omitting that first sentence, but decided to leave it and bask in the glory, lol! (I'm goofy, sorry)

Moved from ID Request.

Either Cheiracanthium or Clubiona
A close-up of the carapace should tell us which. Clubiona has the dorsal groove as mentioned below. These can be very difficult to tell apart!

yellow sac spider
Cheiracanthium inclusum perhaps.

 
Hmm
Personally, I would lean more towards Cheiracanthium mildei because they are encountered more often in the northeast than inclusum. The mildei are more likely to be found indoors, as this one has been, whereas the inclusum species is more often outdoors. They both look very similar, though.

 
got to love photos
A picture says a thousand words, except when it comes to identifying spiders. an examination of the reproductive organs is the best way to go. the faint lower case "t" on the back was about all i could really go on. inclusum is the common one in the central states, not uncommon to find it in buildings and homes, especially this time of year.

I agree with Guy
Reminds me of a Clubiona species. And from what I can barely see of the eye pattern, it seems to match that assumption. Plus, it has a dorsal groove in the carapace (if I'm seeing it correctly).

Another possibility is a Cheiracanthium, whose bites are sometimes thought of as medically significant.

Could be
It looks like that it is a sac spider . Just a guess .
