SumizAI vs SNOQ

What SNOQ is

What SNOQ is

SNOQ is a free, closed-source encrypted notes app for Windows, built in Poland around three principles: working entirely offline, storing data locally only, and AES-256 encryption protecting note content even if a third party gains physical access to the computer. The interface is deliberately minimalist and free of distractions, designed for writing without interruptions from notifications, toolbars, or cloud-sync prompts.

Key features

AES-256 encryption — a standard considered secure even for government and banking applications — protects the content of every note, so losing a laptop or drive doesn't automatically mean exposing saved content. Local-only storage means no data leaves the user's computer without their knowledge — there's no server for notes to end up on, so there's no risk of a data leak from a provider's cloud either. A clean, distraction-free interface keeps attention solely on the written text, with no sidebars, notifications, or blinking elements typical of apps built for engagement.

Who it's for

SNOQ appeals to Windows users for whom the confidentiality of what they write matters more than the convenience of cross-device sync — journalists protecting source notes, lawyers and accountants working with sensitive client data, or simply people who value privacy over cloud features. Writers and journalists looking for a distraction-free environment, where the only thing on screen is the text being written, will also find a good fit here.

Use cases

In practice, SNOQ works well for keeping a confidential professional journal, such as notes from therapy sessions or legal consultations, where a data leak could have serious consequences. An investigative journalist records source details and findings, knowing the data never leaves their computer and is encrypted in case the hardware is stolen. A writer working on a book uses SNOQ's minimalist interface as a place free of social-media distractions and notifications, to focus solely on the text.

Pricing and business model

SNOQ is entirely free but closed-source — users pay nothing to use the app, while also having no visibility into the source code that could independently verify the security of the encryption.

Limitations and what to watch for

The app is Windows-only, so macOS and Linux users have no access to it. The lack of cloud sync, while good for privacy, also means no access to notes from other devices and no automatic backup — losing the drive without your own backup means permanently losing everything saved. The app's closed-source nature, despite the claimed AES-256 encryption, means users have to take the makers' word for it rather than being able to verify the implementation themselves.

AI notes and a local copy

SNOQ has no built-in AI model integration, but thanks to local, encrypted storage it's a natural place for ai notes containing sensitive fragments of AI assistant conversations — draft legal documents generated with AI help, for instance, that shouldn't end up in an external cloud. Pasting such an ai notes entry into SNOQ keeps it encrypted locally, the same as the rest of the app's content.

Offline as a philosophy, not a failure mode

Unlike many apps that treat a lack of internet connection as a temporary problem to work around, SNOQ treats offline operation as the project's foundation — the app never attempts to connect to any server, so there's no risk of accidental data leakage through a forgotten sync feature or background telemetry. For users working in environments with heightened security requirements — no internet access as a matter of policy, for instance — that architecture is an advantage, not a limitation.

Polish origin and trust

An app built in Poland falls under European data-protection regulations, which for some EU users is an additional trust argument compared to tools built outside GDPR jurisdiction. Despite the closed source code, the maker simply being located in a known, predictable legal jurisdiction is sometimes a factor weighed when choosing a tool to store sensitive content.

Minimalism as a focus tool

Turning off everything not directly needed for writing — sidebars, notifications, formatting suggestions — can be hard for some users to adjust to at first, especially if they're used to richer editors with many features visible on screen at once. After an adjustment period, though, many users report that such an interface genuinely shortens the time it takes to start writing — there's nothing to click besides typing itself, so less time gets lost fiddling with settings.

What's worth checking before choosing

Before entrusting SNOQ with truly sensitive data, it's worth checking the technical documentation on the AES-256 encryption implementation, to know exactly how the encryption key is managed and whether there's a risk of losing it along with access to your notes.

Backup as the user's responsibility

Because SNOQ offers no form of cloud backup, full responsibility for data safety in the event of a drive failure rests entirely with the user. It's worth building the habit of regularly, manually copying the encrypted notes file to external storage — a USB drive, an external disk, or an encrypted container in a personal cloud — to avoid a single hardware failure meaning the loss of years of saved content with no way to recover it.

Bottom line

SNOQ is a free, offline, encrypted notes tool for Windows that puts privacy ahead of sync convenience. Anyone who wants ai notes from AI model conversations to land automatically in a portable, open format instead of one app's closed local storage should consider a tool built around that workflow.

Comparison with SumizAI

SNOQ and SumizAI share a concern for data privacy but differ in storage approach and content source. SNOQ keeps everything local and encrypted in one app's closed format on Windows. SumizAI generates ai notes from a conversation with an AI model and saves them as open Markdown files in a vault the user owns, portable across tools and platforms. Anyone prioritizing maximum confidentiality within one closed Windows system will pick SNOQ; anyone who wants ai notes from AI conversations to land in an open, portable format 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 SNOQ 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.
• SNOQ is free and SumizAI costs a dollar a month after a seven-day trial that takes no card. A dollar is what it costs to run accounts and licences without reselling the model; if free is the requirement, SNOQ wins that row outright.
• AlternativeTo's description of SNOQ 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.
• SNOQ 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 SNOQ. SumizAI runs on macOS, Windows, iOS and Android.
• Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
