Hi, I'm Hyder. I built this so you can show anyone exactly what you mean. One click grabs your screen. You mark it, say what you want, and it lands in your chat. Here it is in ten seconds.
What do you want to do?
One minute
This is all most people ever need. Click in your chat first, then do these three things.
It's the round button on your screen. Your whole screen is captured.
Drag around the thing you mean. A row opens with the cursor ready, so just type.
It goes back to your chat, pastes the picture and sends it. Done.
Forgot to click in your chat? No problem. A box appears and waits for you. Click in your chat and press Send.
What stands out
Every screenshot tool can take a picture. These are the things I made it do beyond that.
I wanted recordings to feel filmed by someone watching along. It moves in when you settle, follows as you read and scroll, and pulls back when you pause. If your pointer drifts onto empty space, the camera stays on what matters.
It knows when your cursor is in a chat box and says which one. If it isn't, it asks you to click in one first.
Point at a button, image or text and it lights up. Click, and its name is already in your note.
Type "login button", "images" or any words. Every match gets highlighted.
Auto-Blur finds emails, card numbers, passwords and keys. Have a quick look, as it can miss things.
Organise Steps puts notes in reading order, renumbers them and cleans the wording.
Crop into Tiles cuts every box into one clean sheet. Each tile keeps its number and comment, ready to change.
Crop, mute, add text, and captions like on TV in six designs. Every save is a new version.
Three minutes, once
Unzip Hyduri Capture.zip and drag the app into your Applications folder.
Your Mac checks with you because it came from the internet. Click Open. You only do this once.
Click the camera, click Open Settings, turn on Hyduri Capture, then quit and reopen the app.
Click Send to Chat and do the same for Accessibility.
It opens at startup, with a Dock icon and a menu bar icon. Turn off startup under Settings > Open at Startup. The three round buttons can be dragged anywhere or hidden. To put them in a row, choose Settings > Floating Buttons > Side by Side; choose Stacked Up and Down to stack them again.
Pictures
You'll hear the shutter and see a flash. Turn those off under Settings.
A list opens with every screen and open window on your Mac, browsers first. Click one to capture just that.
Choose Crop and drag around the part to keep. Undo brings the whole picture back.
Web pages bring their address. Capture a page in Safari, Chrome, Arc, Edge, Brave or Firefox and its web address is printed under the picture, so your AI knows exactly which page it is. With split screen or two windows side by side, each page is listed with a tick box: untick any you want left out. Turn it off under Settings. It needs Accessibility, like Select.
Page too long for the screen? Hover over the camera and choose A Long Page. Scroll the window slowly, press Done, and you get the whole page as one picture.
I made two ways to work. Mark on Screen freezes your screen so you draw directly on it. Mini Panel docks to the side while your screen stays live. Choose your default under Settings.
Pictures
Mark is the default: drag to draw a box. Select is the smart one: point, it lights up, click it. Each box gets a numbered row with the cursor ready, so just type. Point at any number below to find it in the picture.
Pictures
Open the conversation and click in its message box, so the cursor is blinking there.
Click the camera and add your notes.
It goes back to your chat, pastes and presses Enter. With several pictures, choose This Picture or All. All of them land in one message.
No cursor in a chat? A small glass prompt asks you to click in your message box. It lights up when it sees your cursor, then you press Send. Search boxes and a browser's address bar don't count.
Want to check before it sends? Turn off Press Enter After Pasting into Chat under Settings, and it stops after pasting.
Pictures
On the frozen screen, the first press takes you back to your real screen so you can scroll. Press it again and that screen joins the set. Add also pastes, opens files or takes pictures from your phone. Each picture keeps its own notes.
Point at a small picture to see it large, and click to open it.
Mark some sections and click Crop into Tiles. You get one sheet of tiles, and that's what gets sent. Each tile is still numbered with its comment, so you can click it and change the words. Undo takes you back to your marks.
Sending several? Send, Copy and Share ask which you mean, with the pictures in front of you. Press 1 for this one, or Return for all of them.
Need a how-to document? Press Share and choose Steps Document (PDF). Each picture becomes one numbered page.
Pictures
Choose Add from Phone, from the menu bar icon or the Add button. Scan the code and pick photos or files. Both must be on the same Wi-Fi. It stops when you close the window.
Copy a photo, wait a few seconds, then choose Paste Image. This needs the same Apple Account on both, with Handoff on.
Open Files picks several at once, from any folder, iCloud Drive or Photos.
Video
Choose Record Whole Screen, or a browser or other window.
With Sound records your voice. Zoom and Follow My Pointer makes the finished video follow you. Both stay on until you turn them off.
A red border shows what's recording. The timer and voice bars sit under the button. None of this appears in the video.
Clicks get a soft ripple, and the finished video appears at the top of Recent.
Video
Click any video in Recent. Each save makes a new version, and the one you opened never changes.
Video
One press writes down everything you said. Your picture stays clean, because the words sit along the bottom.
It listens to your whole video and adds the captions. The first time, your Mac may need a minute.
Pick a look. Move it to the bottom, middle or top. Change the font, size, colour or background.
Pause the video and click the caption. Type the change and press Return.
The captions go into a new copy. Your original stays as it was.
Other languages. Under Caption Design, choose Transcribe Language, then press Transcribe. Arabic reads right to left correctly. It uses Apple's speech service, so your Mac may send that sound to Apple.
After
Pictures/Hyduri Capture, sorted by day.Finding things. Type in Search to find a picture by any word in its comments, a day such as yesterday or Monday, or a kind such as video. The four tile buttons beside it make the pictures bigger. Everything is grouped by day, newest first, and the bin beside a day moves that day to the Trash.
File names read Hyduri Capture Video_222002112026_V1: kind, then time and date (22:20 on 02/11/2026), then version. Image and Crop follow the same pattern. Drag the Recent panel anywhere and it stays there.
After
While you type in a comment, every key types. Press Esc and one key does each thing.
S sends, C copies, V speaks a comment, Tab moves to the next comment. Point at any button to see its key.
Press ?, or the keyboard button in the editor, or choose Editor Keyboard Shortcuts in Settings. Click a key and press the one you want. Delete turns one off, and Reset puts them all back.

After
| What you see | What to do |
|---|---|
| It keeps asking, but the switch shows on | Select Hyduri Capture in that list in System Settings, remove it with the − button, then allow it again. |
| Your Mac won't open it | Download it again from the website. If it still refuses, open System Settings > Privacy & Security, scroll down and click Open Anyway. |
| The picture didn't land in your chat | Click in the message box and press Command-V. With several pictures, only the latest is on the clipboard, and all of them are in Recent. |
| Your phone can't open the page | Check both are on the same Wi-Fi, and allow local network access if your Mac asks. Guest and some office networks block this, so AirDrop is the backup. |
| Select doesn't name things | Allow Accessibility. Without it, the app still finds text and shapes in the picture, but not real button names. Some apps don't share these details. |
| I want to change a picture I already made | Point at it in Recent and press Edit. Pictures you marked here open with their marks and comments ready to change. Pictures from elsewhere open as they are. |
| Some words in the captions are wrong | Pause the video, click the caption, type the change and press Return. Speaking clearly and close to the microphone helps. |
| Transcribe says Dictation is off | It offers to open the setting. Turn on Dictation, give your Mac a minute, then press Transcribe. Your video needs sound. |
| The frozen screen won't go away | Press Esc (twice if a mark is selected) or click the toolbar's X. Marked work is kept in Recent, and Edit there brings your marks back. |
Shortcuts. Every key is listed under No mouse needed.
Nothing is uploaded by the app. A picture or video only leaves your Mac when you send, share or paste it. The one exception is Arabic Transcribe, explained under Captions. Pictures need macOS 14 or newer, and recording needs macOS 15 or newer.
