SumizAI vs Craft

What Craft is

What Craft is

Craft is a notebook and document editor headquartered in Budapest, Hungary, founded in 2019, known for its emphasis on visual polish and smooth navigation between nested documents. Notes can be nested inside one another, and sharing a finished document takes one click, without complicated permission setup.

Key features

Craft's AI assistant runs on three model tiers — Core, Fast, and Max — and helps write, summarize, and brainstorm directly inside a document. The app offers native MCP connections to Claude, ChatGPT, and Cursor, letting you link the editor to external AI tools without manually copying content over. As of 2026, Craft also has a full Android app, previously limited to Apple devices and the web.

Who it's for

Craft appeals to people who value aesthetics and visual enjoyment in an everyday writing tool, who want to combine personal notes with more elaborate documents meant for sharing. Teams already using Claude, ChatGPT, or Cursor get a direct link between those tools and the editor via MCP.

Use cases

In practice, Craft works well for creating polished documents to share with clients or colleagues, building a personal note base with a nested structure, and using the AI assistant to quickly summarize a long document before a meeting.

Pricing and business model

The free plan caps you at 1,500 content blocks and 1GB of storage, while the Plus plan, which removes every content limit, starts at $4.80 a month billed yearly (price varies by region).

Limitations and what to watch for

The 1,500-block limit on the free plan is fairly restrictive for anyone writing regularly, so active users hit the wall requiring a subscription fairly quickly. The Android app is a relatively recent addition, so it may lag the iOS version in maturity.

AI notes through MCP connections

Thanks to native MCP connections to Claude and ChatGPT, content generated in a conversation with those models can land directly inside a Craft document as part of an ai notes entry, without manually copying between apps. That's convenient, but the ai notes entry still ends up inside the current document rather than in a separate, cataloged archive.

Aesthetics as part of the product strategy

Craft has differentiated itself in the crowded notebook market from day one not through features, but through the visual quality of its interface — smooth animations, carefully chosen typography, and thoughtful layout are meant to make writing in the app enjoyable in itself, not just a means to an end.

What's worth checking before choosing

Before choosing Craft, check whether the 1,500-block limit on the free plan is enough for your typical writing volume, and whether the new Android app already has every feature available on iOS.

Bottom line

Craft is an elegant, aesthetics-first notebook with a built-in AI assistant and MCP connections, at the cost of a restrictive free tier. Anyone who wants ai notes from AI conversations to land in a separate, searchable archive rather than only inside the current document should consider a tool built around that workflow.

Comparison with SumizAI

Craft and SumizAI differ in primary focus. Craft is a document editor with aesthetics as the priority and AI as an editorial helper woven in through MCP. SumizAI is a notebook where the conversation with an AI model itself is the entry point — answers worth keeping land automatically as Markdown files 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 beautiful document editor with AI as an add-on will pick Craft; anyone who wants these notes from AI conversations to build a separate knowledge archive 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

• Both mention AI. The difference is whose key it runs on: SumizAI never resells inference — you connect one of seven providers (Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server) with your own API key and pay that provider directly. Check what Craft does with the model bill before comparing prices.
• Craft is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has.
• AlternativeTo's description of Craft 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.
• Both export. SumizAI exports a whole vault as a PDF — summary or full detail — or as a .pptx deck in table-of-contents order, with fifteen slide themes.
• Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
