Has anyone tried Microsoft Copilot for research or coding help? I recently started testing Microsoft Copilot to summarize documentation and explain some code snippets. It’s interesting because it can help with quick explanations, brainstorming, and searching technical information faster. …
I asked Microsoft Copilot to write me a recommendation letter as a joke. The final result was so real that Google’s AI didn’t believe Copilot wrote it.
Am I the only one who finds Microsoft Copilot painfully behind? I really wanted to like it. It’s built into Windows, it’s free, and Microsoft is throwing everything at AI. …
Eh, try using Microsoft Copilot in Word or PowerPoint. It is worthless. If your experience with AI was a Microsoft product, you would think it was a scam too.

… I bounce between Grok, Gemini & Claude. Is ChatGPT even worth it. Grok can do things the other two can't, like read and fetch websites sometimes where Claude and Gemini cannot. Gemini is just someone to feed javascript to when you want to save on Claude tokens.
RIP GROK 2026 I can't even edit the top picture in grok, but chatgpt still allowed it. The restrictions went too far.
We can solve the problem with Grok The Solution: Grok should start a 2nd website called grokillusion. com which disables 'upload image' but has no moderation and is nsfw. Meanwhile, grok. com will continue to have 'upload image' but will be completely moderated and sfw. …
… It comes at the cost of end to end speed - doing something via a grok bot often takes an hour end to end, whereas with a synchronous local prompt it'll take like 10min. The difference is I have to babysit one whereas the other "just works". …
