SumizAI vs EasyNotes

What EasyNotes is

What EasyNotes is

EasyNotes is a simple, open-source notes app for Android, built in Jetpack Compose with an MVVM architecture, available through F-Droid. The app favors a minimalist, material design and full Markdown support, without extra features getting in the way of quickly jotting down a thought.

Key features

An encrypted notes vault protects content from unauthorized access, and the app requests no system permissions beyond what's strictly necessary to run. Dark mode and theme support let you match the look to your preference, and regular updates from the developer (Kin69) keep the app in good shape. Importing notes from other sources makes migration easier for anyone switching from a different notebook.

Who it's for

EasyNotes appeals to Android users looking for a lightweight, fully open-source alternative to bulkier commercial notebooks, especially those using F-Droid as their main app source. People who value simplicity and minimalism over an elaborate feature set get a tool that's exactly what they need.

Use cases

In practice, EasyNotes works well for quickly jotting down short thoughts throughout the day, keeping a simple journal in Markdown format, and as a lightweight alternative to a phone maker's built-in notes app for anyone who prioritizes open-source code.

Pricing and business model

The app is entirely free and open source under the GPL-3.0 license — no ads, tracking, or paid subscriptions. Development is sustained by the open-source community rather than a commercial model.

Limitations and what to watch for

EasyNotes runs on Android only, with no iOS, Windows, or macOS version, ruling out users on other platforms. The feature set is deliberately kept to the basics, so anyone looking for advanced note linking or knowledge graphs will find the app too simple.

AI notes pasted in Markdown format

EasyNotes doesn't integrate with any AI model, but full Markdown support means pasting an assistant's answer as an ai notes entry keeps basic formatting — headings, lists, bold text — with no extra work. The encrypted vault further protects such an ai notes entry from unauthorized access on the device.

Minimalism as an F-Droid design philosophy

Apps distributed through F-Droid often deliberately avoid elaborate feature sets in favor of code transparency and freedom from closed Google libraries — EasyNotes fits that same current, valuing simplicity and verifiability over a long feature list.

What's worth checking before choosing

Before installing, check whether the basic Markdown notebook feature set is enough for your needs, given that EasyNotes deliberately offers no advanced linking between notes.

Bottom line

EasyNotes is a lightweight, fully open notebook for Android with an emphasis on simplicity and encryption, at the cost of advanced features and other platforms. Anyone who wants ai notes from AI conversations to land automatically in an organized archive needs a tool built around that workflow.

Comparison with SumizAI

EasyNotes and SumizAI differ in scale and purpose. EasyNotes is a simple, open-source notebook for Android for hand-written notes. SumizAI is a cross-platform notebook built around the conversation with an AI model itself — question, answer, Markdown note landing automatically in the user's vault, with a title and place in the table of contents assigned without manual work, on your own API key to one of seven providers. Anyone who wants a simple, open notebook exclusively for Android will pick EasyNotes; anyone who wants these notes from AI conversations to be created automatically across multiple platforms will find SumizAI the better-fitting tool.

What SumizAI is

A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk.

A vault is a directory holding base.md, a generated table of contents up to six levels deep, and a notes/ folder with one .md file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist.

The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used.

Every answer kept this way becomes one of these ai notes, ready to search again months later without hunting back through old chats.

Side by side

Where they differ

• AlternativeTo's description of EasyNotes does not mention an AI model. That is the whole starting point in SumizAI: you have a conversation with a model on your own API key, and the answers worth keeping become notes without you filing them.
• EasyNotes is open source (GPL-3.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for EasyNotes. The guarantee SumizAI offers instead is structural rather than legal: the notes are Markdown files in a folder you chose, so they open in any editor whether or not the application is running.
• AlternativeTo's description of EasyNotes does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard .md files to a folder you picked, and an unpaid account can still export all of them.
