Native Windows 11 AI note-taking companion that runs beside your active work.

Key facts

Overview

SideNote Pro is a Windows 11–native note-taking application designed to remain accessible at the edge of the screen while you work in other applications. Unlike browser-based tools (Notion, OneNote Web) or Electron apps, it leverages Windows 11's native APIs to sit persistently as a sidebar companion, reducing the cognitive and interaction cost of capturing ideas or references. The product integrates AI capabilities for note summarisation, automatic tagging, and cross-note linking, allowing users to build interconnected knowledge bases without manual organisation overhead. Under the hood, it uses cloud-based language models for AI features, though the exact vendor and model details are not yet public. SideNote Pro is positioned as a direct competitor to web-based note apps on Windows, trading browser accessibility for native performance and integration. It addresses a specific niche: Windows power users who find tab-switching disruptive and prefer a permanently visible note interface. The product launched via Show HN in September 2026 with minimal public documentation regarding features, pricing, or free-tier availability. Early feedback suggests the core value proposition—proximity and low friction—resonates with Windows-centric knowledge workers, though the roadmap for cross-device sync, offline mode, and integration with popular tools (Obsidian, Logseq) remains unclear.

Who it is for

• Best for: Windows users who need to capture, organise, and reference information while actively working in other applications..
• Avoid if: You use macOS or Linux exclusively, or require offline-first note-taking with zero cloud dependency..

Who this is for

Knowledge workers, researchers, and product managers using Windows 11 who juggle multiple applications and need a persistent AI-assisted scratchpad. Developers, writers, and project managers who benefit from quick note capture and AI-powered summarisation without leaving their primary work window. Teams evaluating Windows 11-native productivity tools as alternatives to web-based note apps.

Who should skip this

macOS and Linux users. Organisations with strict data residency or offline-first requirements. Teams already invested in Notion, Obsidian, or OneNote and satisfied with their workflows. Users who prefer traditional file-based note storage over cloud-backed systems.

Verdict

SideNote Pro fills a genuine gap in Windows 11 productivity tooling by offering persistent, native note access. Its success will hinge on transparent pricing, clear AI capabilities, and timely integration partnerships. Currently worth monitoring for Windows-first organisations, but hold off on migration decisions until the product matures and documentation improves.
