How to Choose a Digital Notes App as Your Second Brain

Choosing a digital notes app for a “second brain” isn’t about locking into a single platform forever—it’s about building a flexible stack with a reliable long-term home for ideas. The core message is that the stakes feel too high because most people treat notes as one app choice, when the real system is a constellation of tools that evolve as needs, workflows, and software capabilities change.

Tiago Forte frames the “second brain” as a layered stack rather than one product: like a computer made of hardware, firmware, operating systems, and apps, knowledge work is distributed across capture tools, storage, organization, collaboration, and creation. In that stack, he argues there’s a missing link for many people: digital notes apps. Earlier generations of software—word processors for publishing, social media for engagement, cloud storage for syncing, and collaboration tools like Google Docs—support structured output and teamwork. Notes apps, by contrast, are the first generation built specifically for creative output, which tends to be informal, messy, and open-ended. That makes notes the “repository” layer where scattered inputs can become durable knowledge.

Forte reduces the case for digital notes to seven requirements: they should be personal (chosen by the individual), informal (like a sketch on a napkin), open-ended (capturing before you know what something is for), multimedia-friendly (text, images, links, PDFs, drawings, voice, and more), transparent (what’s inside is visible immediately), durable (format longevity and upgrades), and centralized (synced across devices without constant exporting). These traits are meant to support the everyday behaviors that already happen—capturing highlights, quotes, photos, and meeting notes—rather than asking people to adopt a futuristic “upload your mind to the cloud” fantasy.

When it comes to choosing among mainstream options, Forte points to three dominant contenders—Evernote, Notion, and Rome—positioned as different “personality types” across the creative process. Evernote is likened to a library: structured, hierarchical, and strong at intake and capture. Rome is compared to a garden: bottom-up, connectivity-driven, and suited to developing ideas through emergent relationships. Notion is treated as architecture: it supports planning, hierarchy, and repeatable structure, making it strong for implementation and integration.

He ties these tool preferences to thinking styles using an assessment based on four creative problem-solving types: clarifier, ideator, developer, and implementer. In a live poll, the group skewed toward developer, clarifier, and implementer, and Forte uses the results to argue that people naturally gravitate toward tools that match how they think—though they can expand over time. The practical takeaway is to start with what feels workable, not what looks perfect, and to prioritize implementation habits over tool features.

Finally, he distinguishes personal vs. collective knowledge management. Forte uses Evernote for his personal organization (casual, informal notes) and Notion for team operations at Forte Labs (dashboards, SOPs, and structured, reusable documentation). The broader lesson: build a minimum viable workflow that moves information through the right stages—capture, organize, distill, express—then iterate. Implementation remains the bottleneck no app can solve for someone else.
