What's New in Second Brain: Smarter Imports, Batch Uploads, and a Cleaner Experience
If you’ve been building out your knowledge base in Second Brain, this update makes the import process faster and more organized.
Multiple tags per import
You can now assign multiple tags when importing knowledge base entries, separated by commas. Previously you were limited to one tag per import, which meant either under-tagging your data. Now you can label an entry as “research, competitors, Q3” in one go.
This is useful when a document genuinely belongs to more than one category. A vendor contract might be tagged “legal, vendors, 2024.” A research PDF could be “market research, product, competitors.” Tagging at import time means your data is organized from the moment it lands, not after the fact.
Batch imports: up to 100 files, or 200 in a zip
You can now import up to 100 files in a single batch, or package up to 200 files into a zip and import them all at once.
Here’s where this becomes practical:
Contracts and legal documents. Drop in a folder of vendor agreements, NDAs, or client contracts and query across all of them. Ask Claude to surface renewal dates, liability clauses, or payment terms without opening each file individually.
Research and reports. Import a set of industry PDFs, analyst reports, or academic papers and treat them as a searchable knowledge base. Ask questions, get summaries, compare findings across documents.
Internal documentation. Product specs, SOPs, meeting notes, onboarding materials. Import the whole folder, tag it by department or project, and anyone on your team can query it in plain language.
Email exports or CRM data. Export a batch of customer conversations or deal notes, bring them into Second Brain, and ask Claude to identify patterns, summarize sentiment, or pull out specific details.
The zip option is particularly useful when you’re migrating an archive or setting up Second Brain for the first time with an existing document library. Package everything, set your tags, import once.
Query your knowledge base from anywhere
Second Brain runs locally on your desktop, but you’re not limited to your desk. By connecting Second Brain to Codex, you can access and query your entire knowledge base from the ChatGPT mobile app. Pull up contract details, search your notes, or ask questions across your documents from your phone, with your data staying local the entire time.
General bug fixes and UI improvements
We’ve also pushed a round of bug fixes and interface refinements based on user feedback. Nothing dramatic, just things that were slightly off and are now right.
If you haven’t tried Second Brain yet, it’s free to download. You connect it to Claude, point it at your data, and start querying it in plain language. No SQL, no dashboards, no setup overhead.
