Three things make a great answer: context, the conversation and one button.

The big picture

OnSubject.AI builds every answer from 3 ingredients. It puts them together the moment you ask:

Each answer is the next thing that you should say. It's written in your style and uses your facts. It also knows everything that was said so far. The answer appears on your screen word by word, so you can read the first line after about half a second.

Scenarios

A "Scenario" is one situation that you want help with: a job interview at a specific company, your weekly operations meeting, a debate, a sales pitch or an architecture review. Each Scenario is a folder on your PC, like the one below. It also remembers your conversations.

• Create, rename, duplicate or delete Scenarios in the app (＋ New Scenario), or directly in File Explorer. A new folder appears as a new Scenario at once. If the folder is empty, it gets a template that's ready to fill in.
• Switch Scenarios from the list at the top of the window, or from your phone. Duplicating a Scenario is the fastest way to make a new one for a similar situation: "Job Interview · Northwind" becomes "Job Interview · Contoso" in a minute. The copy doesn't have any conversations yet.
• Listening belongs to one Scenario. You can't switch Scenarios while you listen, so every line is saved where it belongs. To switch, stop listening first.
• Edit anywhere. Use the built-in editor or your favourite text editor. Your changes are used at once, even in the middle of a conversation.
• The app comes with 5 starter Scenarios: Job Interview, Technical Interview, Work Meeting, Debate & Negotiation and Sales Pitch. Each one has sensible answer settings.
• Keep them anywhere. The Scenarios folder can be in OneDrive or any other synced folder, so it follows you to another PC.

Placing your context: what goes where

The way you give OnSubject.AI its context makes the biggest difference to the quality of its answers. The rule is simple: put instructions that apply to every Scenario in GENERAL.md, instructions for this Scenario in START-HERE.md, and facts in files. GENERAL.md sits in the Scenarios folder and is sent first. A new Scenario does not repeat it. Name each file and folder for what it holds. The instructions tell the AI to choose what to read from those names, and to also read a file when another instruction points to it.

START-HERE.md: 3 short sections

# Job Interview · Northwind

## Who I am and what I want
I'm Radu, a Director of Operations with 22 years in logistics and e-commerce.
I'm interviewing for Head of Operations at Northwind.
The company is opening in 3 new countries in 2027.
I want to lead a team of 30+ people.
I want hybrid work (2 days remote) and a package of around €110k.

## How to answer
- Give me the exact words to say. Saying them should take 60 to 90 seconds.
- Use a real story from my files, with one number in it. Never invent experience.
- Be warm and confident, but never arrogant. Never criticise past employers.
- If the question is about salary, start with the value that I bring. Then give the range.
- When it fits, end with a short question back to them.

## Context
<!-- Only for me: the hiring manager is Ana Ionescu. She used to work at DHL, and she values data. -->
This is interview 2 of 3, with the hiring manager and the CFO. It lasts 60 minutes.

• Who I am and what I want goes first: your role, the situation and your goal. Answers are always written for you, so OnSubject.AI needs to know who "you" is.
• How to answer is a list of rules: tone, length, structure, what to always do and what to never say. Short bullet points work better than paragraphs.
• Context holds the few facts that every answer needs: who's in the room, the agenda and what's at stake. Anything bigger belongs in a file.
• Comments are private. Text between <!-- and --> is only for you, and it's never sent. Headings that you leave empty are skipped, so leaving the template's hints in place doesn't make your answers start later.

Reference files: the facts

Drop files into the Scenario folder, and they're read automatically. This works for PDF, Word, PowerPoint (with speaker notes), Excel, RTF, Markdown and text, notebooks, any source code, and images such as diagrams, whiteboard photos or screenshots. You can also link a folder that's somewhere else, like a code repository or a shared drive. If you like, you can limit it to some file types, such as *.md;*.pdf.

Documents and knowledge bases

OnSubject.AI adapts to how much you give it:

• A normal Scenario (a CV, a job description, a few PDFs) is read whole for every question. Every answer can use every page.
• A big document set (a knowledge base, a product wiki or a code repository with thousands of files) is indexed on your PC and searched for every question. Each answer gets your instructions, the core documents at the top of each folder, a map of the folders and the passages that best match what was just said.
• Deep search (Pro and Ultimate): when the best answer needs more than those passages, OnSubject.AI opens more of your documents by itself. While it reads, you see "Opening contract-acme.pdf". Those answers start a moment later, and they include the exact clause.
• Always up to date. When you add, edit or delete a file, the index is updated within seconds. Only what changed is read again.
• Earlier conversations in the Scenario are read like your documents, so new answers stay consistent with what was already said. More below.

Answer style, length and language

Each Scenario decides how its answers look. Pick the style that matches how you speak under pressure:

Listening

OnSubject.AI turns speech into a live transcript, sentence by sentence, while people are still talking.

When you ask for an answer, OnSubject.AI finishes the sentence that is being spoken right away, without waiting for a pause. That way, the last words of the question are always included.

Listening belongs to the Scenario where you started it. Everything that it hears is saved there. To switch to another Scenario, stop listening first.

The transcript

The transcript is the question. OnSubject.AI answers what's in it, so you're in control of it:

• Correct any word. Click a line and type. You can fix misheard names, numbers and half-heard questions. Answers always use your version, and the lines that you corrected are marked.
• Remove what would confuse it. That can be small talk, noise or a wrong guess. The ✕ next to a line removes it from the conversation, and so does erasing its text. Undo brings it back.
• Type a question. Type in the box under the transcript and press Enter. Your question is added as a Typed line and answered at once. This works well for "Summarise the decisions so far" or "What's our best counter-offer?".
• A Follow-up line. Choosing one of the 3 questions under an answer adds it here, marked Follow-up, and answers it at once.
• Answer one specific line. Every line has its own answer button. Use it when the question came a minute ago.
• Start fresh. Clear transcript starts a new conversation. The previous one stays saved in the Scenario (and yes, Undo works here too).
• How far back it looks. Each answer reads the last few minutes of the conversation. By default, that's 5 minutes, so answers start quickly and stay focused. When you want a recap of a whole meeting, raise it to as much as an hour (Settings › Audio & transcription).

Getting answers

Each of these has a keyboard shortcut that works from any app, even while the window is hidden. You can change them, or turn one off, in Settings › Hotkeys.

• It understands follow-ups. Every question also includes the answers that were already given in this conversation. That way, a question like "can you expand on that?" makes sense, and new answers stay consistent with earlier ones. You can turn this off.
• Three questions at the end. Every answer offers 3 questions that might follow next, or that go deeper. Click one, on the PC or on your phone. The question is added to the transcript as Follow-up, and its answer is written at once. Those questions stay with the answer, so they come back when you browse earlier answers or reopen the Scenario.
• Browse earlier answers with ‹ ›, or swipe through them on your phone. The PC follows along. Answers from earlier conversations in the Scenario are there too, marked Earlier in this Scenario. Copy one with a click.
• Remove an answer that you didn't use (🗑). It then no longer counts as something that you said, so follow-ups won't build on it. Undo brings it back.
• Stop an answer whenever you like. You can also make the answer text as large as you need to read it at a glance.

Screenshots and areas

Some questions aren't spoken, like a coding exercise, a chart on a shared slide or a clause on screen. Add what you see to the question.

• Which monitor: it's the one that you used last. You can pick another one from the ▾ menu next to Answer + screen. The menu shows a small picture of each monitor.
• From your phone: Photo › Screenshot works like Answer + screen. With 2 or more monitors, the phone shows a picture of each one, and you tap the one to capture.
• A part of the screen: drag a box. You can move it, resize it from the edges and corners, or draw a new one. Enter, a double-click or Send sends it, and Esc cancels. The area is remembered, even after a restart.
• It stays out of the screenshot: OnSubject.AI hides itself while it captures the screen, then comes back.
• Detail: choose a higher detail when small text on a large or 4K screen needs to be readable.

Window and hotkeys

Conversations that it remembers

Each Scenario remembers its conversations. As you talk, OnSubject.AI writes the conversation into the Scenario's own Conversations folder. Each conversation is one clean text file (Markdown). Every line has its time and speaker, and every suggestion is marked [OnSubject.AI] right where you asked for it.

# Weekly Ops Sync, 2026-10-16 09:14:22

**09:14:22 Them:** I have a quick update from the supplier, and it's not great.
**09:14:31 Them:** The shipment slips 3 weeks. Can we absorb that?

> - Action: Procurement, by **Friday**

**09:15:02 Me:** Partly, and we don't have to pay for all of it. Section 7.2...

• It comes back. When you pick the Scenario again, tomorrow or next week, the conversation is back on screen with its answers.
• Answers build on it. Earlier conversations are read like your documents, so new answers stay consistent with what was already said, decided or promised.
• You don't lose anything. Every line is written down as it's spoken, so the conversation survives even a sudden restart.
• A new conversation starts when you clear the transcript. It also starts by itself after 2 quiet hours. The previous one stays in the folder.
• Forget something by deleting its file, or the whole folder. Answers that you removed are left out of the file. A duplicated Scenario doesn't have any conversations at first.
• Save writes a copy wherever you like, to keep or to share. Use it for meeting minutes, interview notes or evidence.
