For capturing ideas mid-work, Tucky wins on friction: its edge-docked notes, ⌥Space ask-from-any-app bar and $4/month Plus plan (launched September 8, 2026, macOS only) scored 22/25 on my Stanley-derived criteria, against Reflect at 18/25 ($10/month, best for cross-device recall) and Apple Notes at 15/25 (free, weakest cross-note AI). Kenneth Stanley's stepping-stone principle is the reason capture speed matters more than organization.
Every founder I coach has the same leak: a good idea arrives in the middle of a task, and the act of saving it costs the task. You switch apps, a notification catches you, and twelve minutes later the original thread is gone. So when a small Mac app called Tucky took the number-four spot on Product Hunt on September 8, 2026 with 251 upvotes by promising notes that live "at the edge" with an agent inside, I installed it the same afternoon and ran it against the two tools I already use for the same job.
The criteria are the actual argument, so they come first. In Why Greatness Cannot Be Planned, Kenneth Stanley and Joel Lehman show that ambitious outcomes are reached by collecting stepping stones, discoveries that rarely resemble the destination, and that objective-driven systems systematically discard them. Their novelty-search robot solved a maze 39 times out of 40 while the goal-seeking version managed 3, because the goal-seeker threw away the "irrelevant" moves. A capture tool is a stepping-stone collector. So the questions I care about are Stanley's: how cheaply can I collect a stone, does the tool let it stay strange rather than forcing it into a folder, and can I later find the interesting ones. Here is how the three tools scored, each criterion out of five.
| Criterion (Stanley lens) | Tucky 1.1.2 | Reflect | Apple Notes |
|---|---|---|---|
| Capture friction (cost of collecting a stone) | 5 | 4 | 4 |
| Stays out of the way during the task | 5 | 3 | 3 |
| Lets stones stay unstructured (no forced hierarchy) | 4 | 4 | 3 |
| Interestingness retrieval (ask across notes) | 4 | 4 | 2 |
| Ownership and privacy | 4 | 3 | 3 |
| Total (out of 25) | 22 | 18 | 15 |
Tucky's score comes almost entirely from the first two rows. The app sleeps as a thin stripe on the screen edge; you reach over, the titles fan out, you pick one and write. Hold ⌥Space from any application and a bar appears to search, dictate, or ask your notes a question without leaving what you were doing; ⌘J asks about the note you have open. Version 1.1.2 is about 15 MB, needs macOS 15 or later, and keeps everything encrypted on the Mac. The free tier is five notes with no AI, no voice, and no connectors. Plus is $4 a month and adds unlimited notes, the reasoning models for writing and cross-note questions, voice dictation in 60-plus languages, and connectors to Gmail, Google Calendar, Docs, Sheets, GitHub, and Notion. In a week of use it worked as advertised: half-formed pricing thought captured, back in the spreadsheet in under ten seconds.
Reflect is the tool I have relied on for two years, and it loses here for a reason that is also its strength. It is a networked notebook with backlinks, end-to-end encryption, an iOS app, calendar integration, and an AI layer that transcribes voice notes and answers questions across your graph. It costs $10 a month billed annually ($120 a year) with a 14-day trial and no free plan. For retrieval it is excellent; for capture mid-task it means opening a full window, and a full window invites me to tidy, link, and drift. Stanley would call that objective creep: the tool nudges you to organize the stone before you know what it is.
Apple Notes is free, ships inside macOS Tahoe 26 (26.6.2 as of mid-August 2026), and Quick Note from the hot corner is genuinely fast. Apple Intelligence's Writing Tools will summarize or proofread the note in front of you, but there is no ask-across-all-my-notes agent, which is the retrieval row where it scores a two. It remains the best answer for anyone whose main capture device is an iPhone, since Tucky has no phone app at all.
The limits are real. Tucky is one week old, from a tiny team, Mac-only, and the $4 plan is "$4 of AI" with a top-up option marked coming soon, so heavy voice or model use will hit a ceiling I could not yet measure. Its agent sends note titles with your question and reads a body only when you approve it, a good default that also means less background magic than some expect. One aggregator lists Plus at $12 a month; the app's own site says $4. And my scoring is one week and one job; for long-form writing or team wikis the ranking would flip.
What I actually do now: Tucky for the stones, Reflect for the map. The interesting fragments accumulate at the screen edge during the day, and once a week I ask Tucky which notes touch the same theme and move the ones that still feel alive into Reflect, where they can be linked. Stanley's point is that you cannot know in advance which stone matters, so the only thing worth optimizing is the cost of picking one up. Right now, on a Mac, Tucky makes that cost the lowest of the three.
