SumizAI vs Lisble

What Lisble is

What Lisble is

Lisble is a free shopping-list app from Japan, available on Android and as a web app (PWA). Unlike general-purpose notebooks, Lisble focuses on a single task — the shopping list — and adds purchase history on top of it, to prevent buying the same item twice or forgetting something bought regularly.

Key features

Purchase history with date and time lets you check when an item was last added to the list, making it easier to plan recurring purchases. A left-/right-handed layout switch rearranges buttons to reduce the chance of tapping the wrong item while quickly checking things off in the store. A built-in Amazon search lets you add a product to the list straight from search results. Multi-line notes on list items leave room for extra detail — brand, size, aisle number. Drag-and-drop sorting organizes the list manually, and the app supports both Japanese and English.

Who it's for

Lisble appeals to people doing regular grocery or household shopping who want a simple tool instead of a full notebook with features they don't need for this one task. Families sharing shopping duties can use the history to avoid two people buying the same item on the same day.

Use cases

In practice, Lisble works well for weekly grocery runs, where history suggests what's usually bought around this time of the month, for quickly adding an item found in Amazon search results, and for checking off items one-handed in the store, thanks to a layout matched to the dominant hand.

Pricing and business model

The app is entirely free, available through Google Play as an Android app and as a progressive web app running in the browser with no store install required.

Limitations and what to watch for

Lisble is narrowly specialized for shopping lists, not a general notebook or knowledge-management system — there's no room here for longer notes, linking documents, or building a knowledge archive. Anyone looking for a multi-purpose note-taking tool should check other entries on this alternatives list instead.

Where shopping lists fit in the broader note ecosystem

Shopping lists are one of the most common, though often overlooked, types of everyday notes — short, repetitive, deleted after use. A specialized tool like Lisble handles that task better than a general notebook, because the whole interface is optimized for quickly adding and checking off items rather than writing longer text.

AI notes as a complement to a simple list

Lisble offers no AI-model integration and no room for longer notes — if someone wants to save a recipe generated by an AI assistant as an ai notes entry, they need a separate note-taking app alongside Lisble, since a shopping list and an ai notes entry with a recipe are two different kinds of content requiring different tools.

What's worth checking before choosing

Before downloading, it's worth checking whether the web (PWA) version runs smoothly enough on a given phone, if you'd rather not install a separate app from Google Play.

Bottom line

Lisble is a simple, free tool for one task — shopping lists with history that prevents duplicates. Anyone who needs a separate place for ai notes from AI conversations will have to reach for an additional app alongside Lisble.

Comparison with SumizAI

Lisble and SumizAI operate in entirely different categories. Lisble is a specialized shopping list; SumizAI is a notebook built around a conversation with an AI model, where answers worth keeping land automatically as Markdown files in a vault the user owns. Anyone who just needs a shopping list will pick Lisble; anyone who wants these notes from AI conversations to build a searchable knowledge archive will find SumizAI the right tool — and could use both at once, each for its own purpose.

That is our reading of the record. For AlternativeTo's own wording, see its page for Lisble — the facts above were read on 2026-08-16.

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 Lisble 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.
• Lisble 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, Lisble wins that row outright.
• AlternativeTo's description of Lisble 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.
• Lisble runs in the browser. SumizAI is a desktop and mobile application, and on the desktop the vault is a folder on your own disk rather than a document in someone's cloud.
