SumizAI vs Focal - Notes & Tasks

What Focal - Notes & Tasks is

What Focal is

Focal is a notes and tasks app from the Hungarian company Vargary, organized around a tree structure — ideas, projects, and to-dos are laid out like folders within folders, in a simple outline format. Instead of a flat list of files or tags, the user always knows where a given note sits within the hierarchy.

Key features

Versatile note types let you create tasks, Kanban boards, and dynamic filters within the same tree structure. A tagging system lets you categorize and filter notes independent of their position in the hierarchy, and both rich and plain text editors give formatting flexibility. Sync works across all devices with automatic backup, and sharing features let you invite others to view or edit specific notes or entire sections with permission control.

Who it's for

Focal appeals to people who naturally think hierarchically and want one tool combining notes, tasks, and Kanban boards in a coherent tree structure, instead of separate apps for each content type.

Use cases

In practice, Focal works well for organizing multi-level projects with nested sub-tasks, keeping a personal note base with a clear thematic hierarchy, and sharing selected branches of the tree with a team without exposing the entire structure.

Pricing and business model

Focal offers a free version with limited functionality and a $1-a-month subscription unlocking the app's full capabilities — one of the cheapest paid options among the notebooks compared here.

Limitations and what to watch for

The tree structure, while natural for many, can feel limiting for people who prefer free-form, networked note linking over a rigid folder hierarchy. The free version has limited functionality, so full capabilities require a subscription.

AI notes within the tree hierarchy

Focal doesn't integrate with any AI model, but pasting an assistant's answer as an ai notes entry into the right spot in the tree structure immediately places it in context alongside thematically related notes and tasks. Tagging such an ai notes entry makes it easier to find later, regardless of nesting depth.

Hierarchy as a deliberate design choice

At a time when many modern notebooks bet on networked linking and knowledge graphs, Focal deliberately returns to a classic tree structure, on the assumption that for many users a clear hierarchy is easier to manage than a sprawling web of connections.

What's worth checking before choosing

Before choosing Focal, check whether a tree structure fits how you organize your projects, and exactly which features are limited in the free version.

Bottom line

Focal is an affordable, tree-structured notebook combining notes, tasks, and Kanban boards, at the cost of less flexibility than networked linking. Anyone who wants ai notes from AI conversations to land in the system automatically needs a tool built around that workflow.

Comparison with SumizAI

Focal and SumizAI differ in organizing model and content source. Focal builds a hierarchical tree structure with hand-written notes and tasks. SumizAI generates these notes directly from a conversation with an AI model — question, answer, Markdown file in the vault with a title and place in the table of contents assigned automatically, on your own API key to one of seven providers. Anyone who wants a hierarchical tree structure for their own tasks and notes will pick Focal; anyone who wants these notes from AI conversations to be created automatically 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 Focal - Notes & Tasks 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.
• Focal - Notes & Tasks 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 Focal - Notes & Tasks 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.
• Focal - Notes & Tasks also does tasks. SumizAI does not — no boards, no due dates, no projects. It files knowledge, not work.
• Both search. SumizAI's search reads the whole note — title, summary, body and the original question and answer — rather than titles alone.
• Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
