A day in the life: Wisebase vs Second Brain

A researcher is building a knowledge base for a market analysis project. They need to review competitor YouTube videos, industry TikTok trends, a few academic PDFs, LinkedIn thought leadership posts, and recent web articles. In Wisebase, the PDFs and web articles work great — the deep research agent can even scan 100+ pages automatically. But the YouTube videos, TikToks, and LinkedIn posts? Wisebase can't process those.

In Second Brain, every source goes in: the videos, social posts, PDFs, and articles all live in one searchable space. They can ask "What trends are emerging across all my research?" and get answers drawing from academic papers and TikTok trends equally.

Then they open a Visual Board to map the entire market analysis spatially. It's an infinite canvas where they place all their research — the competitor YouTube videos, industry TikTok trends, PDFs, LinkedIn posts, and articles — as visual nodes. They create multiple AI chat nodes: one identifying competitive threats, another spotting market gaps, a third drafting the executive summary. They add Notion-like pages right on the board to build the final report as insights emerge. Everything stays visible at once: sources, AI analysis threads, and the deliverable itself. Wisebase gives you a mind map and deep research agent. Visual Boards give you a multi-threaded workspace where your sources, several AI conversations, and your working documents coexist in one view.

Wisebase goes deeper on documents. Second Brain goes wider on content types — and gives you a spatial canvas to think with all of it.

Pricing at a glance

Wisebase (by Sider) offers a free tier with basic features and 30 daily credits. Sider Pro plans start at around $10/mo. Second Brain starts at $6/mo with all AI models included. Both include Chrome extensions. The trade-off: Wisebase includes deep research capabilities and academic paper access that Second Brain doesn't have. Second Brain includes multimedia content processing and Visual Boards that Wisebase doesn't have.

If you're an academic researcher, Wisebase's paper database may be worth the premium. For broader knowledge management, Second Brain covers more ground.

Who switches from Wisebase to Second Brain — and why

Content creators and knowledge workers who tried Wisebase for its AI features but found it too document-focused. The typical scenario: great for reading PDFs, but no way to add the TikTok that inspired their latest project or the YouTube interview they want to reference. Also users who want Visual Boards for spatial knowledge mapping.

What you give up: Wisebase's deep research agent (automated 100+ page scanning), academic paper search across 350M+ papers, and mind map generation. These are genuinely powerful features for academic and deep research workflows.
