notea
Notea is an online secure notes application introduced in 2016 by a Danish startup. It offers text, images, and links, and is available as a web service and native desktop and mobile apps. The platform emphasizes end‑to‑end encryption, using AES‑256 and secure shredding of local caches. Multi‑factor authentication and single sign‑on integration support enterprise deployments. The interface includes tagging, full‑text searching, and revision history. Companies adopt it for sensitive project details, compliance documentation, or personal diaries, while individuals use it for confidential notes. Notea integrates with file services such as Dropbox, Google Drive, and Office 365, and provides APIs for custom back‑end integration. In 2019 a collaborative editing feature and invite controls were added. The 2021 launch of Notea Pro introduced ISO 27001‑certified compliance features and advanced API capabilities for larger organizations. The company maintains a community forum and blog that discuss best practices for secure note management and shares contributions to open‑source encryption libraries. By mid‑2024, Notea reported annual revenue of approximately $13 million and over 2 million active users worldwide. Critics point out that the free tier’s storage limits may be restrictive, and some security audits have identified concerns about server‑side key management. Nonetheless, the service is frequently cited as a well‑balanced note‑taking solution that combines usability with strong privacy safeguards, and continues to evolve to meet the demands of modern productivity ecosystems.
