# SumizAI vs MyEncryptedNotes

Looking for a MyEncryptedNotes alternative? SumizAI and MyEncryptedNotes side by side: price, licence, platforms and what each one actually does.

## What MyEncryptedNotes is

MyEncryptedNotes keeps personal notes truly private — a fast, lightweight, and fully offline encrypted notepad for Windows. All data is protected locally using ChaCha20-Poly1305 encryption, delivering modern, high-performance security with no cloud dependency whatsoever. It's an app built around one specific promise: what you write stays exclusively on your computer, encrypted with an algorithm considered one of the more modern cryptographic standards used in practice today.

Key features:

ChaCha20-Poly1305 encryption is a modern authenticated-encryption algorithm valued for high performance even on weaker hardware and strong security properties, often used as an alternative to older standards in apps requiring both speed and solid protection. Fully offline operation means the app never connects to the internet to process your notes — the entire encryption and decryption process happens locally on the device. A lightweight build translates into fast startup and minimal system resource use, unlike sprawling notebooks with dozens of features the average user rarely touches. Interface simplicity supports the app's single, main goal — secure text storage — without distracting users with unnecessary extra features found in more sprawling competitors.

Who it's for:

MyEncryptedNotes reaches Windows users who need a place for genuinely confidential information — backup passwords, personal data, thoughts that by definition shouldn't land in anyone's cloud. People working with sensitive professional data, where even a single leaked note could have serious consequences, will find a tool here built specifically with that risk in mind. Users distrustful of cloud providers and their privacy policies will appreciate a fully local model with no compromises.

Use cases:

Someone managing backup passwords for accounts they don't want stored in a cloud-synced password manager writes them into MyEncryptedNotes as an extra offline layer of protection, physically separate from the rest of their digital life. A consultant working with confidential client data notes project details in an encrypted file, confident that even if the laptop were stolen, the content would remain unreadable without the key. Someone keeping a private journal with very personal thoughts chooses MyEncryptedNotes over popular cloud notebooks precisely for the guarantee of full data locality, with no leak risk from a potential breach of the cloud provider's own systems.

Pricing and business model:

MyEncryptedNotes is a paid app — the user pays once or periodically for the software, instead of relying on a free tier funded by ads or data sales. That model directly reinforces the privacy promise — the developers have no incentive to analyze note content, since their revenue doesn't depend on user data.

Limitations and what to watch for:

Windows-only availability rules out users on other operating systems, a significant limitation when working across multiple devices with different systems. No cloud sync, while good for privacy, also means no automatic backup — losing the notes file without your own backup copy means permanent data loss. The app doesn't yet have many likes on AlternativeTo, suggesting niche, still-building name recognition.

What to check before choosing:

Before making MyEncryptedNotes your primary home for sensitive data, it's worth checking whether the app offers any access-recovery mechanism if you forget your password — with genuinely strong encryption, no such password usually means permanent loss of access to the content, which is the price of uncompromising security. It's also worth establishing your own routine for backing up the encrypted file to external media.

Encryption versus everyday convenience:

Strong encryption always comes with a trade-off against convenience — without cloud sync, notes are available on only one device, and the password has to be remembered on your own, with no email-reset option typical of online services. For people who prioritize security over convenience, that trade-off is fully acceptable, but it's worth consciously accepting it before moving important data into the app.

Privacy versus ai notes from AI conversations:

MyEncryptedNotes has no built-in AI features or integration with conversational models — a deliberate design choice focused solely on secure text storage. For people who want to locally encrypt the content of sensitive ai notes generated elsewhere during a conversation with an AI assistant, MyEncryptedNotes can serve as a secure destination after manually copying content over from another tool.

ChaCha20-Poly1305 in context:

Choosing this particular encryption algorithm isn't arbitrary — ChaCha20-Poly1305 has become popular as a fast, secure alternative to older AES-based standards in contexts where both performance on weaker hardware and resistance to known classes of cryptographic attacks matter. It's widely used in modern security protocols, giving some assurance that MyEncryptedNotes' developers built the app on a proven, current cryptographic foundation rather than an outdated or proprietary scheme of uncertain strength.

The threat model it protects against:

MyEncryptedNotes primarily protects against two scenarios: a stolen or lost device, where the encrypted file stays unreadable without the password, and accidental or deliberate access by third parties with physical access to the computer. It does not protect against threats like keyloggers or malware running in the background while you're actually typing a note — it's worth understanding the limits of what a given tool actually secures, rather than treating encryption as a universal shield against every possible threat.

Bottom line:

MyEncryptedNotes is a narrowly focused, fully offline encrypted notepad for Windows — for anyone who prioritizes absolute privacy over sync convenience or AI features, it's a solid choice for storing the most sensitive content.

Comparison with SumizAI:

MyEncryptedNotes and SumizAI address entirely different notes needs. MyEncryptedNotes is a specialized, local text vault, with no AI integration at all, built solely around maximum offline security. SumizAI is a notebook built around conversation with an AI model — answers worth keeping become ai notes saved as Markdown files in a user's vault, with the ability to sync across devices. Anyone who needs an absolutely private, offline place for the most sensitive data will pick MyEncryptedNotes; anyone who wants their ai notes from AI assistant conversations to land automatically in an organized, portable archive will find in SumizAI a tool for an entirely different purpose. A deliberate user might run both at once, keeping data requiring maximum confidentiality separate from ai notes from everyday AI work.

**Key facts**

## 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.

## Where they differ

- AlternativeTo's description of MyEncryptedNotes 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.
- MyEncryptedNotes is paid software. Compare the two numbers directly: SumizAI is one dollar a month, one plan, and your AI provider bills you separately for the model you chose.
- AlternativeTo's description of MyEncryptedNotes 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.
- MyEncryptedNotes advertises encryption. SumizAI answers the same worry a different way: on the desktop the notes never leave your disk, and the material a question sends to the model is capped at the table of contents plus at most five notes — and the app shows you which five it used.
- AlternativeTo lists no mobile version of MyEncryptedNotes. SumizAI runs on macOS, Windows, iOS and Android.
