What It Is

My Atoms is a knowledge management tool designed for personal reading and writing workflows. Its core goal is to bring highlights, excerpts, and ideas from sources such as Kindle, Medium, and the web into one unified system. The product is organized around three concepts: Atom, Source, and Stream. An Atom is a small unit of knowledge, a Source records where it came from, and a Stream automatically syncs the flow of knowledge.

Core Features and Integrations

Based on the available information, the main workflow in My Atoms is capture, review, integration, and creation. Users can save selected text from web pages via a browser extension, or create notes directly in the Web App. Kindle and Medium highlights can be synced about every 6 hours after connecting an account, with manual sync also supported. It also offers a Note Anywhere extension for web annotation, supports organizing content by source and tag, and includes a stats calendar for tracking reading and writing activity. Current third-party integrations mainly focus on Kindle, Medium, browsers, and export flows, with an Open API available for custom integrations.

Pricing and Data Portability

Pricing is very simple: the free plan is permanently $0, supports up to 500 atoms, and includes all integrations and browser extensions. Pro costs $3/month or $30/year, with unlimited atoms, all integrations, browser extensions, and priority support. It is marked as offering a free trial, though the duration is not specified. Payments are processed by Paddle.com. The product clearly supports exporting all atoms at any time, which is helpful for migrating a personal knowledge base.

Pros, Cons, and Best-Fit Users

Its strengths are a clear concept, lightweight onboarding, and low pricing. It is well suited to heavy Kindle/Medium readers, writers, individual researchers, and fans of atomic notes. The limitations are also clear: by design, it does not support images or videos as atoms; the available text does not indicate team collaboration, permissions, an enterprise admin console, or audit capabilities; and there is limited information on security and compliance, with no visible mention of SOC 2, GDPR, encryption policies, or similar details. In addition, the project is maintained by an independent developer. Although there is a commitment to long-term self-funded maintenance, enterprise buyers should still carefully assess service continuity.

Access from China and Alternatives

Access from mainland China cannot be determined from the text alone. Since payments are handled through Paddle, they may be affected by bank card support or foreign-currency payment conditions. If Chinese-language ecosystem support or localized experience is important, alternatives to compare include flomo, Notion, Obsidian, Evernote, Readwise, and Heptabase. Among them, Readwise is closer in terms of highlight syncing, while Obsidian and Notion are better suited for deeper organization and extensibility.
