SumizAI vs acreom

What acreom is

What acreom was

acreom was an actionable knowledge base for developers, designed to centralize personal and team work context in one place and help ship code faster. The app combined notes with task management in a developer-oriented format — integrated with tools like GitHub and Linear, rather than being another general-purpose notebook. The project was available under the GPL-3.0 open-source license, letting the developer community inspect the code and adapt the tool to their own needs. Its AlternativeTo listing marks acreom as discontinued — worth factoring in before adopting the tool today.

Key features

acreom combined Markdown notes with a task list in one view, letting a note fragment turn directly into an actionable task without switching apps. GitHub integration allowed referencing specific issues and pull requests right from project notes, shortening the distance between documentation and actual code. A calendar view tied scheduled tasks to notes for a given workday, giving developers one point of reference instead of a separate calendar and a separate notebook. Open-source code under GPL-3.0 allowed self-hosting and security audits by more technical teams.

Who it was for

acreom targeted developers and small development teams who wanted to keep project documentation, code-review notes, and a task list in one place integrated with GitHub, instead of scattering that information across Notion, Jira, and a separate notebook. People who valued open code and the option to self-host their data found in acreom a rare combination of developer-focused functionality and open-source philosophy.

Use cases

In practice, acreom worked well for documenting architectural decisions directly tied to specific commits and pull requests in a project's repository. A developer preparing for code review could keep notes with comments that automatically linked back to the right pull request on GitHub. A small startup team planning a sprint could combine a task list with technical notes in one calendar view, avoiding drift between what was planned and what was actually recorded.

Pricing and business model

acreom ran on a freemium model — the basic app, built on open GPL-3.0 code, was available at no cost, with paid add-ons such as cloud sync or expanded team integrations. That model let individual developers use full core functionality locally for free, paying only for the convenience of cloud services.

Limitations and what to watch for

The most important limitation is the project's status — acreom is marked discontinued, meaning no new updates, security patches, or technical support from its creators. Anyone considering the tool today should expect to be running the last available version with no guarantee of further development, unless they choose to maintain their own fork of the open code. Teams needing an actively supported tool would be better served by a living, developing project.

AI notes in the context of a discontinued project

acreom never had native AI model integration, so preserving an ai notes entry from a conversation with an assistant would have required manually pasting text into the right project note — much like many other classic developer notebooks from before the AI era. Given its "discontinued" status, that integration should not be expected to ever arrive, making acreom an unattractive choice for anyone building a workflow around ai notes from AI today.

The legacy of an open-source project

acreom's fate illustrates a common pattern for ambitious open-source projects — an enthusiastic launch, active development for a while, then the founding team stepping away even though the code stays publicly available. For the developer community, that means the tool doesn't disappear entirely, it just goes dormant — someone could theoretically revive it, fork it, and continue development, but that requires community initiative rather than automatic support from the original creators.

Lessons for choosing developer tools

acreom's story is a good lesson when choosing tools for daily work — it's worth checking not just the feature list but also GitHub repository activity, commit frequency, and whether the creators respond to bug reports. A tool with fewer features but actively maintained can be a safer long-term choice than a feature-rich app whose development could stop at any moment.

Migrating data if you decide to leave

For current acreom users looking to move to an actively developed tool, the key point is that data was stored as plain Markdown files on disk — which makes migrating to another file-based notes app relatively straightforward, with no risk of being locked into a closed format. That's one real advantage that survives a discontinued project: even an abandoned tool built on open files doesn't take the user's data down with it. That property — data always accessible outside the app — should be treated as a minimum standard when choosing any future notes tool, regardless of how long a given product plans to stay on the market.

What's worth checking before choosing

Before anyone considers acreom today, it's worth checking the date of the last code update on GitHub and whether an active community fork is continuing development — being open source means the project can theoretically live on in the community's hands even if the original team abandoned it.

Bottom line

acreom was a solid, developer-focused combination of notes and tasks with GitHub integration, but its "discontinued" status makes it a risky choice for the future without active support. Anyone looking for an actively developed tool where ai notes from AI conversations land automatically in the system without manual copying should consider a living alternative.

Comparison with SumizAI

acreom and SumizAI shared a philosophy of files as the foundation of notes, but acreom is today a discontinued project while SumizAI is an actively developed product. acreom focused on combining notes with developer tasks and GitHub integration. SumizAI generates ai notes directly from a conversation with an AI model, turning valuable answers into Markdown files in a vault the user owns. Anyone who once sought out acreom for its GitHub integration should today consider an actively supported tool; anyone who wants ai notes from AI conversations to land automatically in their own file system will find SumizAI a tool built exactly for that purpose.

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 flags acreom as no longer developed. Whatever you put into it, you will eventually have to get back out — which is an argument for keeping notes in a format that outlives the application, and the reason SumizAI writes plain .md files into a folder you already own.
• AlternativeTo's description of acreom 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.
• acreom is open source (GPL-3.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for acreom. The guarantee SumizAI offers instead is structural rather than legal: the notes are Markdown files in a folder you chose, so they open in any editor whether or not the application is running.
• acreom 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 acreom 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.
• acreom is described as something more than one person uses at once. SumizAI is not: there are no shared vaults, no comments, no permissions and no sync between devices. If the work is a team's, that is a reason to pick acreom over SumizAI.
