Your best thinking is buried in chat history.
You ask an AI something brilliant, get a great answer. A week later it is gone, lost in an endless list of conversations with titles you never chose. Copying answers into a notes app works for about three days, until the first busy week comes along, the habit breaks and the answers go back to sitting in a chat history nobody searches.
Before
Hundreds of chats. No titles, no structure, no way back to the answer you need today.
With SumizAI
One library. Every answer a note, every note in its chapter, every link alive.
From question to knowledge in three steps
Ask
Chat with the model you prefer: Claude, GPT, Gemini, Llama via Groq, hundreds via OpenRouter, or a model running locally in Ollama.
It becomes a note
When the answer is done, SumizAI writes one of your AI notes: a clear title, a one-line summary, the key points. The original question and answer stay word for word.
It files itself
The note lands in the right chapter of your table of contents, links to the notes it relates to, and merges with a near-duplicate instead of piling up.
Everything your AI notes need. Nothing you have to maintain.
A table of contents that writes itself
Chapters are laid out from what you actually ask about, and every new note is filed where it belongs.
No near-duplicates
Ask the same thing twice in March and May and you get one richer note, not two half-notes.
Links that never break
Notes link to each other and show what links back. Rename a note and every link follows.
Search that remembers the conversation
Find the sentence you half-remember. Search reads titles, summaries, notes and the original chat.
Bring what you already have
Paste text, drop Markdown and text files or a PDF — each one becomes notes in your library.
Export to PDF and PowerPoint
Turn a whole vault into a PDF briefing or reference, or an editable .pptx deck in 15 themes, in table-of-contents order.
Notes in your language
Ask in English, keep notes in Arabic, Czech or Japanese. Source material is translated, the original kept.
Vaults that keep topics apart
Work, research and a side project each get their own library, language and table of contents.
Private by design
Your notes are plain Markdown files in a folder on your Mac. Open them in any editor, back them up with Time Machine, keep them forever. They work without SumizAI.
Your notes never reach our servers
Vaults live only on your Mac. We cannot read them, because we never receive them.
Your key, your provider
The app talks straight from your Mac to the AI provider you chose, with your own API key — no middleman, no markup on tokens.
Fully offline AI if you want it
Connect a local Ollama and not a single word leaves your computer.
No ads. No selling data.
Your account exists only to hold your subscription and to let you use it on your Macs. Delete it in the app at any time.
Made for people who learn for a living
Students & researchers
Every explanation becomes one of your AI notes, filed by topic, ready for the exam or the literature review, and exportable to PDF.
Developers & engineers
Keep every hard-won answer about your stack. Search it next month instead of asking again.
Consultants & writers
Research once, reuse forever. Turn a vault of notes into a client deck in PowerPoint.

Questions
Do I need an AI API key?
Yes. SumizAI works with your own key from Anthropic, OpenAI, Google Gemini, Groq or OpenRouter, a server of your own, or a free local model in Ollama. You pay your provider directly at their rates, which is why the subscription can stay this small.
Where are my notes stored?
In a folder on your Mac, as one Markdown file per note. Nothing is uploaded to us. You can open, copy, sync or back up the files like any others.
What happens if I cancel?
Your AI notes stay exactly where they are, as plain files you own. The subscription pays for the app's AI features; your library never depends on it.
Which Macs are supported?
Any Mac with macOS 12 Monterey or newer, Apple silicon or Intel.
Which languages does it speak?
The app is available in 16 languages, and each vault can keep its notes in a language of its own.
Stop losing your best answers.
Your next question could be the first of many AI notes you keep for years.
