How long does it take for AI tools to pick up site updates and recommend your Software?

I was testing how LLMs rank products in our space by asking vague buyer questions like "what's the best tool for X." We showed up on Gemini, but ChatGPT kept listing older competitors that haven't updated in years.

It made me realize how inconsistent these AI recommendations are compared to traditional Google SEO.

If you added comparison pages, structured data, or an llms.txt file recently, did you notice any real difference in how models cite you?

Ever built a productivity setup that just felt like extra work?

I remember setting up this massive notion workspace with heaps of databases, tags, and weekly trackers.

It looked awesome at first but after a week or two updating the whole thing took more time than doing actual tasks. Eventually I just gave up and went back to writing things down on a quick sticky note.

Curious if anyone else overbuilt their todo system and ended up throwing it away?

After one particular case, I lost trust in AI-generated diffs

During the refactor of a validation helper, the agent also replaced a strict comparison with a loose one. The tests passed due to being generated alongside with the source code itself. It took me two days to discover this bug, because a user pointed out that empty string is considered to be a valid ID.

I still use agents on a daily basis. Now I write about 40% of the code manually. But I check every line of the diff and write my own test for everything related to authentication and validation myself.

Where is the line for you? I would like to know if people have a rule that they apply when deciding which part of the code cannot be modified by an agent, or it just remains a gut feeling.
