SumizAI vs smasi

What smasi is

What smasi is

smasi is a local, personal wiki for easily recording work descriptions, experience reports, checklists, and personal knowledge. Unlike elaborate knowledge-management systems, smasi aims for simplicity and speed — the app is available across many platforms, from Mac and Windows computers to Android and iOS phones and tablets, and even Chrome OS, so access to notes is possible from practically any device the user happens to be using.

Key features

The personal wiki format lets related entries link to each other, forming a structure resembling a small, private encyclopedia of the user's professional and personal knowledge. Checklists built directly into notes make it easy to document repeatable procedures, such as the steps needed to onboard a new employee or a checklist before an important presentation. Experience reports let users record lessons from finished projects in a structured form that's easy to return to for a similar task later. Broad platform availability means the same knowledge base follows the user both in the office on a computer and out in the field on a phone.

Who it's for

smasi appeals to people who document their professional work in a structured way — consultants recording lessons from successive client projects, technicians maintaining documentation for repairs and procedures, or managers building a library of a team's proven practices. People who value local data storage over full dependence on a third-party cloud find smasi a suitable tool for keeping a private knowledge base.

Use cases

In practice, smasi is useful for documenting an equipment repair procedure a technician might return to months later for a similar fault, instead of solving the same problem from scratch. A consultant wrapping up a project records an experience report — what worked, what didn't, what unexpected obstacles came up — building a personal library of practical knowledge over time. A manager preparing an onboarding checklist for a new hire keeps it in smasi, where it's easy to update after each new recruitment round.

Pricing and business model

smasi runs on a freemium model — the basic version is available at no cost, with an upgrade path to a paid plan for people who need more storage or advanced options. That model lets anyone try the app as a daily tool for documenting work before committing to a paid subscription.

The daily documentation ritual

Many smasi users treat the app as a daily habit rather than a tool opened sporadically — a short entry after finishing a task, a note from an important client call, a checklist update after noticing something's missing from it. That regular, low-effort threshold means the knowledge base grows organically in the background of daily work, instead of requiring a separate "tidy up my notes" session every few weeks that often gets postponed indefinitely.

Cross-platform availability in practice

The fact that smasi works the same way on a computer, phone, and tablet matters in real daily work — a field technician logs an observation on their phone right after a repair, instead of trying to remember it until they're back at the office. A consultant traveling for business adds a takeaway from a client meeting on a tablet before it gets lost in the rush of other obligations. That immediacy of capture often matters more for documentation quality than any advanced editing feature.

Limitations and what to watch for

The simplicity that's smasi's main strength also means fewer advanced features than elaborate knowledge-management platforms offer, such as sophisticated inter-note linking or a graph view. As a smaller, niche app, smasi doesn't have as large a community or plugin ecosystem as more well-known tools in the category. It's also worth checking the exact scope of cross-platform sync, to make sure notes really are available wherever you need them.

Privacy as a deliberate choice

People documenting sensitive professional information — client data, internal company procedure details, observations from confidential projects — value smasi's local character as an alternative to notebooks requiring full trust in an external cloud. That doesn't mean no syncing, but it does mean data stays under the user's control to a greater degree than in tools built entirely around a provider's central database.

AI notes from AI assistant conversations

smasi has no built-in AI model integration, so preserving a ai notes entry from a conversation with an assistant means copying a fragment of the response and pasting it manually as a new wiki entry. For people already keeping checklists and experience reports in smasi, adding ai notes from AI conversations there too can make sense — it keeps one coherent professional knowledge base in a single place, though it requires a manual step for every such ai notes entry.

One place for many kinds of knowledge

The advantage of keeping checklists, experience reports, and any ai notes from AI conversations in one app is that when searching for a specific piece of information, there's no need to remember which of several different tools it was saved in. Someone preparing for a project similar to one from a year ago can find both the formal experience report and looser ai notes captured while consulting an AI assistant about that earlier task in the same place, building a fuller picture of the situation than the report alone would give.

What's worth checking before choosing

Before building a large base in smasi, it's worth settling on your own entry and category naming system, to avoid chaos as the wiki grows. It's also worth testing sync between two different devices if you plan to use the app on both a computer and a phone.

Bottom line

smasi is a simple, cross-platform tool for keeping a personal wiki of work descriptions, checklists, and experience reports. Anyone who wants ai notes from AI assistant conversations to land in the same base automatically, without manual pasting, should consider a tool built specifically around that workflow.

Comparison with SumizAI

smasi and SumizAI build different kinds of personal knowledge base. smasi is a wiki filled in by hand by the user — work descriptions, checklists, lessons from experience. SumizAI generates ai notes directly from a conversation with an AI model, turning valuable answers into Markdown files saved in a vault the user owns, with no manual retyping. Anyone already keeping a knowledge base in smasi can treat SumizAI as an additional source of these notes from AI conversations, exported later into the main wiki as a complement to their own hand-maintained documentation.

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 smasi 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.
• smasi 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 smasi 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.
• smasi is described in terms of linking notes together. SumizAI links them too, but deliberately without a syntax of its own: a link is an ordinary Markdown link, [Title](file-name.md), and the model may only point at a file that actually exists. There are no wiki-style [[…]] links to lose on export.
