With Sequoia released - the "Writing Tools" invoking Apple's AI are available in most apps now via the context menu (e.g. select a paragraph/block of text and right-click and the context menu or menu bar shows the menu entry "Writing Tools" wherein you can get the Apple AI ecosystem to rewrite, proofread etc - however this is not available yet in Thunderbird 128.4.2 when composing/editing an email. See the screenshot below - I'm writing this using Safari and it's available here - even for this little message... I appreciate this is a North American facility at present and you have to fully enable US English on your Mac and then enable "Apple Intelligence" in system settings...but once you have done this, the facility is available in most apps unless the API chosen doesn't support it. Any thoughts if / when Thunderbird might get updated to use the API to invoke or enable this? If I can think of the one writing app where I spend most of my time, it's eMail.....while it's true I can select a paragraph and pop it over to Notes via copy-paste, invoke the AI there and paste it back - that's not as convenient. thoughts....jc
