The website finds your character for me.
The addon you want is

See
https://medium.com/raidbots/how-to-install-and-use-the-simulationcraft-addon-5b64d0835a0b for its explanation.
You would use this addon to provide Raidbots with a list of alternate gear that is in your bag, that it can’t get by looking up your character. This can then be used by Raidbots Gear Compare and similar functions that rely on checking whether gear in your bags would b better.
I just did a Quick Sim of your character to get baseline Stat Weights for a simple 5-minute single-target encounter. These are the results (will disappear in 2 days):

What this shows is that for your character, using your current Talents and your current gear, p[laying the given rotation perfectly against a target dummy for 5 minutes, you would put out about 10.7K DPS, plus or minus 10% to 20% depending on procs and RNG.
And that your current stat values for that encounter are
Intellect 4.62
Critical Strike 2.87
Versatility 2.54
Mastery 2.24
Haste 2.04
- If you added 116 Intellect to your character, each point would add an average of 4.62 DPS (this does not guarantee that 1 Intellect = 4.62 DPS)
Change one piece of gear, or something about the encounter, and these values will be affected.
This is a sim for a “Dungeon Slice”, 5 minutes in a Mythic-Plus kind of environment:
https://www.raidbots.com/simbot/report/6xJP9VcDmFKmvqMZjr9ry6
which gives stat weights as
Intellect 5.88
Critical Strike 3.68
Versatility 3.24
Haste 3.05
Mastery 2.49
This would not be surprising, because with AoE and Cleave you will be using a different mix of spells, which will get different amounts of benefit from the various stats.
Icy-Veins and others do try to help with their original recommendation of the stat priority for a generic Warlock with specified Talents in a target set of gear, but at Mythic level, where you are playing, it is worth getting more tailored recommendatons.
