ThinkerNotes vs Baseplate

ThinkerNotes helps you capture and organize ideas from books, podcasts, and conversations into a personal knowledge base. It uses AI to link related notes and surface relevant insights when you need them, turning scattered thoughts into connected knowledge. Designed for founders, content creators, and knowledge workers, it acts as a second brain that remembers and connects your ideas over time. You can import highlights from Kindle and organize notes by source, topic, or project for easy retrieval. The platform emphasizes two-way linking between notes, helping you discover patterns and connections that spark original thinking. ThinkerNotes also focuses on preventing idea loss by making your knowledge searchable with semantic AI, not just keyword matching. The tool is accessible via a web interface with secure data handling and offers export options to keep your knowledge yours. It is free to start with no credit card required, making it easy to begin building your personal knowledge system.

Baseplate is a backend-as-a-service platform built for LLM applications. Teams use its multimodal context database to store embeddings, text, documents, images, links, and code in one spreadsheet-style workspace instead of juggling separate vector and relational stores.

The platform covers the full retrieval stack: dataset sync from tools like Google Drive, S3, Box, and SharePoint, configurable semantic or hybrid search, prompt templates with version control, and deployable API endpoints. You can also ship one-click Slack, Discord, and Teams bots from the same console.

Baseplate targets engineering and product teams shipping retrieval-based LLM features, from customer support bots and internal knowledge hubs to teaching assistants and e-commerce shopping guides. It launched as a Y Combinator W23 company, though the marketing site and app currently show infrastructure and suspension issues while documentation remains online.
