SumizAI vs Compendio

What Compendio is

Compendio is a privacy-first personal planner built in Europe, combining tasks, goals, habits, projects, notes, journaling, and calendar in one calm, distraction-free space. Fully GDPR-compliant, encrypted, ad-free, and running on EU infrastructure, Compendio positions itself as a European alternative to US-based productivity apps, whose personal-data protection standards are sometimes looser than what's required in Europe. The application comes from Romania, within the European Union, and runs as an online SaaS service under a freemium model.

Key features and functionality

Integrating seven different areas of self-management - tasks, goals, habits, projects, notes, journaling, and calendar - into one application means users don't have to juggle separate tools for each of these aspects of their life. The "calm, distraction-free space" approach sets Compendio apart from many competing productivity tools, which often overwhelm users with an excess of notifications, gamification, and stimuli meant to hold engagement at all costs. Full GDPR compliance and running exclusively on European infrastructure means user data never leaves European Union jurisdiction, which carries real legal and practical significance for many European users and organizations. Data encryption and the complete absence of any ads reinforce Compendio's positioning as a tool that puts user privacy and well-being above maximizing time spent in the app, typical of an ad-based business model.

Who it's for

Compendio is aimed primarily at European users deliberately looking for an alternative to the market-dominant US productivity apps, for whom GDPR compliance and EU data location are important selection criteria. People tired of the overwhelming number of features and notifications in competing tools appreciate Compendio's calm, minimalist approach to managing everyday life. Users wanting to combine different aspects of personal organization - tasks, goals, habits, journaling - in one place, instead of scattering them across several separate apps, find in Compendio a comprehensive solution. Organizations and professionals in sectors requiring strict compliance with data-protection regulations choose Compendio for its architecture built from the ground up around GDPR requirements.

Use cases

In everyday use, Compendio serves as a central place for planning the day, combining a task list with a calendar and habit tracking, letting the full picture of one's time and priorities be seen in a single view. People working on long-term goals use the goals module together with projects and tasks to break big ambitions down into specific, actionable steps. Journaling in the same application where tasks and goals are managed allows for natural reflection on progress, without switching between a separate notebook and a time management tool. European companies with strict GDPR compliance requirements deploy Compendio as a productivity tool for their employees, confident that organizational data stays fully compliant with local regulations.

Pricing and business model

Compendio runs on a freemium model, offering free access to core planner functionality and a paid subscription unlocking advanced features across all seven integrated modules. This model lets users test the coherence and convenience of Compendio's integrated approach before deciding on a paid subscription, especially attractive to people who value European data privacy standards.

Comparison with SumizAI

Compendio and SumizAI operate in different areas of digital life. Compendio is a comprehensive personal planner combining seven different organizational functions, with no built-in integration with artificial intelligence. SumizAI, by contrast, is a platform enabling conversations with multiple AI providers at once, unrelated to managing tasks, goals, or habits. Someone organizing their life in Compendio might additionally use SumizAI when they need AI help planning a strategy to achieve a specific goal or analyzing patterns recorded in their journal.

AI notes in an integrated planner

Compendio users often keep their own ai notes in the notes module from consultations with language models about their goals and projects, combining personal reflection kept in the journal with an external AI perspective. Thanks to integrating notes with tasks and calendar in one application, such ai notes can be directly linked to a specific project or goal, instead of remaining detached, loose entries. GDPR compliance and data encryption mean even the most personal ai notes about difficult life decisions stay fully protected, in line with European privacy standards. Compendio's calm, distraction-free interface also encourages longer, more thoughtful work on such ai notes, instead of jotting down thoughts hastily under pressure from notifications.

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 Compendio 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.
• Compendio 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 Compendio 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.
• Compendio 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.
• Compendio also does tasks. SumizAI does not — no boards, no due dates, no projects. It files knowledge, not work.
• Compendio 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.
• Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
