A day in the life: Notion vs Second Brain

Imagine you're a marketer building a campaign strategy. Throughout the week you save a TikTok about email funnels that's getting millions of views, a LinkedIn carousel breaking down copywriting frameworks, a 40-minute YouTube tutorial on landing page optimization, and a PDF case study from a SaaS company that tripled conversions. This is a normal Tuesday.

In Notion, you'd create a separate page for each resource, manually type up your takeaways, tag them, and link related pages together. The TikTok? You'd probably just paste the URL and hope you remember what it was about. The YouTube tutorial? Maybe you take timestamped notes while watching. It's doable, but it's work — and the connections between these resources live only in your head.

In Second Brain, you paste all four links. The AI watches the TikTok, reads the LinkedIn carousel, processes the YouTube tutorial, and ingests the PDF — automatically tagging and connecting everything. Then you open one chat and ask, "What are the best email funnel strategies across everything I've saved?" You get a synthesized answer pulling insights from all four sources, with citations.

And here's where it really pulls ahead: open a Visual Board and lay everything out spatially — the TikTok, the PDF, the LinkedIn carousel, and an AI chat node — all visible at once on an infinite canvas. It's a multi-node workspace where you can have several AI conversations running alongside your sources and Notion-like pages, all in front of you at the same time. In Notion, you'd be tab-switching between pages. In Second Brain, the whole picture is right there. Both tools store your knowledge — Second Brain lets you see and use it all at once.

Pricing at a glance

Notion's free tier is genuinely generous for personal use — unlimited pages and blocks for individuals. Notion Plus runs about $10/month, and if you want Notion AI, that's an additional $10/month add-on on top of your plan. So for an individual with AI features, you're looking at roughly $20/month. For teams, Notion's pricing is competitive and the collaboration features justify the cost.

Second Brain starts at $6/month and includes all top AI models — Claude Opus, GPT, Grok, and Gemini — with no separate AI add-on. There's no "AI tier" to upgrade to; every plan comes with full AI capability. For individual AI-powered knowledge management, Second Brain delivers more AI capability for less money. For teams that need databases, wikis, and project management, Notion remains the better value.

Who switches from Notion to Second Brain — and why

The most common switchers are content creators and marketers who hit Notion's limits with multimedia content. They love Notion for documents and wikis but found themselves copying TikTok transcripts manually, taking screenshots of LinkedIn posts, and losing track of video insights buried in text notes. Second Brain solves this specific pain point — it natively understands video, social media, and audio content without any manual transcription.

What you give up: Notion's powerful databases, team wikis, Kanban boards, and project management features. These are real strengths that Second Brain doesn't try to replicate. Many users keep Notion for team work and project coordination while using Second Brain as their personal AI knowledge engine — the two complement each other well.
