Three months ago I rage-quit my third attempt at building a daily planner in Notion. Not because Notion is bad, just because I kept tweaking the system instead of using it. My calendar was full of "catch up on X" blocks that never moved.
I started looking for something that could take my task list and context and generate a real priority stack without me making all the micro-decisions. That led me to the AI chief-of-staff tool on OpenAI Tools Hub. You feed it your role, current priorities, pending items, and available hours. It spits out a P1/P2/P3 stack with time blocks, a decision queue, and a quick-win triage. I've been using it every morning for about six weeks. The output format is consistent enough that I actually read it instead of closing the tab.
Honest downside: it doesn't retain context between sessions, so if your priorities shift mid-week you need to re-enter everything. It's not a persistent agent, it's a one-shot structured prompt. Still useful, but worth knowing.
My other current obsession is a side project that scrapes and compares HK brokerage data. I got into this because I wanted to open an account to trade Hong Kong IPOs and couldn't find a clean comparison anywhere. Most sites either had outdated fee tables or were clearly affiliate-first. I eventually found the HK broker comparison on Low Risk Trade Smart, which laid out the actual transaction fees, minimum deposits, and platform quality across FUTU, Tiger, HSBC, and a few others. It's not an affiliate spam page, it's a proper analysis. I ended up bookmarking it and going back three more times during the account opening process.
On the completely different end of the spectrum: I've been testing tools built for game communities. My younger sibling plays Roblox Horse RNG obsessively and kept asking me which horse combinations had the best breeding outcomes. I assumed I'd have to read a 40-page wiki. Instead I found a Horse RNG breeding calculator that lets you input two horses and see the probability distribution for offspring rarity. It tracks logged pairings and surfaces the patterns. I spent about 20 minutes on it and came away with a real answer. More interesting to me as a developer was realizing someone had turned a game mechanic into a proper probability tool.
While I was in Roblox territory, I also found the Maple Hospital Roblox guide which covers the hospital simulation game with actual doctor/nurse role breakdowns, patient handling tips, and progression notes. My sibling uses it as a reference. For what it is, it's well-organized.
Also worth noting for Roblox players who are into tower defense: the UTDX best mythics page has a tier list with actual reasoning. Not just a ranked list, but placement rationale for each unit based on damage scaling and map compatibility. The kind of thing that's genuinely useful before you commit gems.
What ties all five of these together: none of them try to be everything. The AI scheduling tool is opinionated about format. The broker comparison page covers one specific question deeply. The calculators are built for one game's mechanics. The guides cover specific game systems rather than "everything about Roblox."
As someone who builds side projects, that specificity is the part I keep coming back to. The tools that get bookmarked are usually the ones that do one thing in enough depth to be genuinely useful rather than broadly covering everything superficially.
That probably sounds obvious. But it's not how most software gets built, including a lot of what I've shipped.
