# SumizAI vs Hoshiyomi

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

## What Hoshiyomi is

Hoshiyomi is an AI assistant named Sakura, designed as a friendly, personalized conversational companion. The understated description "Say hi to Sakura" suggests an approach centered on personality and the user's relationship with the assistant, rather than showcasing a list of technical features, which sets Hoshiyomi apart from more corporate-sounding AI tools.

A paid-only model, available online and on Android, suggests Hoshiyomi targets users willing to pay for a personalized, engaging conversational experience, likely inspired by aesthetics and conventions popular among fans of anime culture and Japanese digital entertainment, judging by the assistant's name alone.

A US origin combined with a Japanese-sounding assistant name points to a growing trend of building AI products that draw on Japanese pop-culture aesthetics, aimed at a global audience of fans of that style, regardless of the company's own country of origin.

Someone using Sakura as a daily companion for conversation, brainstorming, or simply unwinding after a busy day gradually holds hundreds of conversations with the assistant on various topics, some of which contain genuinely valuable thoughts or ideas worth remembering long-term. Without extracting those most valuable fragments outside the app itself, they get lost in the thicket of everyday, casual conversation.

SumizAI complements Hoshiyomi exactly at that point: the most valuable thoughts and ideas from conversations with Sakura can be saved as ai notes in a local Markdown file, separating what's worth keeping long-term from everyday, fleeting casual chat. Someone using Hoshiyomi both for relaxation and for thinking through important decisions ends up with ai notes containing only those most valuable fragments, easy to find without scrolling through hundreds of casual conversations.

These tools complement each other: Hoshiyomi provides an engaging, personalized conversational companion for everyday use, while SumizAI ensures the valuable thoughts emerging from those conversations survive as ai notes, regardless of how much the everyday, casual chat history with Sakura keeps growing.

It's worth adding that the distinction between everyday conversation and lasting knowledge deserves particular conscious attention with assistants designed to be companionable and engaging — it's easy to get drawn into a pleasant conversation without noticing that an idea worth saving to ai notes has come up, before it disappears into the next round of looser small talk.

Someone using conversations with Sakura as a form of daily reflection, wrapping up the evening by summarizing what happened that day and what it means going forward, gradually develops the habit of ending such a session with a short these notes capturing the single most important thought or takeaway from the conversation. After a few months, such a collection of these notes becomes a personal reflection journal, far richer and more systematic than a traditional diary, because each entry emerges from a dialogue with an assistant helping organize one's thoughts, rather than in solitude in front of a blank page.

Someone going through a difficult period in life, using Sakura as a safe space to express emotions and thoughts they don't yet feel ready to share with people close to them, may especially appreciate keeping these notes as a way of tracking their own process of coping with difficulty. Reviewing such notes from months earlier makes it easier to notice real emotional progress that's often invisible day to day but becomes clear in hindsight, once worries recorded earlier turn out to no longer apply.

## 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

- Hoshiyomi is a place to have the conversation. SumizAI is not a chatbot — the conversation is the input, not the product. What comes out of it is a `.md` file with a title, a place in `base.md` and a duplicate check against the notes already in the vault. If you only want to talk to a model, you do not need SumizAI.
- Hoshiyomi 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 Hoshiyomi 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.
- Hoshiyomi 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.
