I got Tonex and I can confirm, it came with a really slim version of Amplitube, and I can insert a 'Tonex' capture into Amplitube.fyi - regarding Ryan's vid above which points out that Tonex drive captures were not actually usable anywhere, I got an Amplitube / Tonex update today which mentions the following change:
"This update offers tighter integration with TONEX with the addition of a new piece of gear called TONEX Stomp. With TONEX Stomp you can use any TONEX Stomp Tone Model anywhere within the AmpliTube signal chain."
The Tonex 'chain' is pretty slim (as noted). Amp, Cab, Compressor, Reverb....that's it.
BUT, the amp/captures sound excellent!! I have not done any of my own yet, just playing around with what comes with Tonex, and some User downloads from their cloud. Honestly, I wish it had more effects in the Tonex UI, but the tones are better than the Neural plugins that I tried (and the Quad Cortex). No more of the ear fatigue that came with the QC.
For the price, this is a great tool to have on my laptop!
