Capture signals, hunches, and lessons with a single keystroke. Build a personal library of notes and sources you can draw on with perfect recall — whenever your business needs it.
Download for MacInsights strike anywhere — mid-article, mid-podcast, mid-call. Leo is your context-aware notebook: capture signals, hunches, and lessons with a single keystroke, and the source comes with the note automatically. Your jots can stay short, because the article, the timestamp, the page they came from are already attached. Months later, your library still knows where every idea came from.
Highlight a passage in your browser, reader, or podcast app and hit the shortcut. The note saves with the source attached. No app-switching, no copy-paste, no "I'll find this later."
Article URLs, podcast timestamps, video frames, page numbers — captured automatically with every note. Your notes can be a single line because the context is already there.
Months of notes, every one with its source. Search finds the actual moment, not just the words you typed. The pile of bookmarks, screenshots, and "I read this somewhere" becomes something you can actually use.
Ask Leo across your library and the sources behind it. Or bring your own model — Claude, GPT, Gemini — and point it at the library you've curated, with the full context attached. Most notes apps lock you into one model, or none.
Capture interview quotes, churn reasons, JTBD insights, and feature requests as they come in. Every note keeps the call, the customer, and the recording timestamp attached.
Track pricing changes, positioning shifts, and product launches across the companies you watch. Articles, screenshots, and podcasts captured at the source.
Save VC objections, pitch feedback, intro threads, and term sheet notes in one place. Walk into the next conversation with everything that came before it.
Build a record of the experiments, customer reactions, and competitor moves shaping how you sell. Each note tied to the call or article that prompted it.
Note interview signals, reference checks, and onboarding decisions across every candidate. The call, the resume, and your impressions in one place.
Keep a decision log of what worked, what didn't, and why. Sourced to the meetings, calls, and reading that shaped each call.
From the keepers
At sixteen, Rockefeller bought a small notebook for ten cents and called it "Ledger A." He recorded every cent earned, spent, and given to charity in it for the rest of his life. The discipline he taught himself in those pages — accounting for the small things — became the operating logic of the largest company of its era.
In 1868, Carnegie wrote himself a private memo laying out a plan: retire by thirty-five, give away his wealth, devote his life to letters. He kept the page. It became the blueprint for the Gospel of Wealth and the libraries he later built across two continents — a single notebook entry that outlined a second life.
Bell's experimental notebook page from March 10, 1876 — now at the Library of Congress — holds the first sketch of the telephone and the words "Mr. Watson, come here. I want to see you." Decades of subsequent notebooks tracked his work on aeronautics, the photophone, and the education of the deaf.
Edison's Menlo Park lab kept roughly 3,500 notebooks — five million pages of experiments, sketches, and dead ends. He logged everything because the pattern of failure was the only way to find the path forward. The phonograph, the carbon filament, and 1,093 patents trace back to those pages.
Ford carried "jot books" his whole career — small pocket notebooks for ideas, expense tallies, and turns of phrase. The pages that survive show him obsessing over inches and ounces. The same compulsive pursuit of efficiency turned the Model T into the most-produced vehicle of its century.
Before Kitty Hawk, the Wrights spent four years filling notebooks with wind-tunnel data, sketches of wings, and corrections to the prevailing aerodynamic tables. The first powered flight wasn't a moment of inspiration — it was the last entry in a methodical log that ran from 1899 to that December morning in 1903.
Disney filled story-sketchbooks for every film — pencil thumbnails, dialogue snippets, music cues. The 1934 sketchbook for Snow White ran to several volumes; he showed it to investors before any animation existed. The studio was sold on the strength of the notebook.
