Vibe Coding a Velocity Studying App with Python in Simply 15 Minutes

Picture by Writer | Ideogram

Image this: You will have an concept for a pace studying app. As an alternative of spending hours researching which Python modules and libraries to make use of, coding the completely different elements, and debugging syntax errors, you merely describe what you need in plain English. Inside minutes, you are tweaking font sizes and discussing person expertise enhancements together with your AI coding accomplice.

That is “vibe coding” — a collaborative strategy the place pure language directions assist get to purposeful functions by iterative dialog. It isn’t about changing conventional coding expertise, however about accelerating the journey from idea to working prototype.

Immediately, I will stroll you thru how I constructed a completely purposeful RSVP (Fast Serial Visible Presentation) pace studying app in simply quarter-hour utilizing Python.

Going From Thought to Implementation

 
Say you might have an concept, and wish to vibe-code it. Should you already use ChatGPT, Claude, or Gemini, you’ll be able to proceed to make use of the identical. I like to recommend you check out these prompts (or higher variations of the identical) to see what you’re in a position to construct.

Step 1: Describe What You Wish to Construct

You may open with a easy request:

“I might prefer to create a command-line pace studying software utilizing Python that implements RSVP (Fast Serial Visible Presentation) method. The app ought to run on Ubuntu, show phrases sequentially at adjustable speeds, and embody fundamental controls primarily based on keyboard inputs. May you present a clear, well-structured implementation with correct error dealing with?”

No technical specs. No detailed necessities. Only a clear intent. That is the place vibe coding is tremendous cool — you begin with the what, not the how.

This offers us a very good start line. From that preliminary immediate, you need to get a purposeful terminal-based pace studying software:

class RSVPReader:
    def __init__(self, textual content, wpm=250, chunk_size=1):
        self.textual content = textual content
        self.wpm = wpm
        self.phrases = self._prepare_text()
        self.current_index = 0
        self.is_paused = False
        self.delay = 60.0 / (wpm * chunk_size)

The preliminary implementation contains:

• Textual content processing: Splitting content material into readable chunks
• Velocity management: Configurable words-per-minute
• Interactive controls: Pause, resume, navigate, pace adjustment
• Progress monitoring: Visible suggestions with progress bars
• File assist: Learn from textual content recordsdata or direct enter

For the entire implementation of the category, you’ll be able to test the rsvp_reader.py file.

Step 2: Improve Person Expertise

When requesting enhancements, we used descriptive, goal-oriented language:

“I might like to reinforce the visible presentation by centering the textual content show within the terminal window and rising the font emphasis for higher readability. May you modify the code to make the most of the terminal’s middle space extra successfully whereas sustaining clear, skilled output?”

This prompted terminal manipulation:

def _get_terminal_size(self):
	"""Get terminal dimensions for responsive format"""
	strive:
    import shutil
    cols, rows = shutil.get_terminal_size()
    return cols, rows
	besides OSError:
    	    return 80, 24  # Smart fallbacks

Now the speed-reading app nonetheless works. Nevertheless, we are able to add some remaining enhancements.

Step 3: Refine Person Interface Necessities As Wanted

Our remaining iteration request specifies the necessities clearly:

“I might prefer to refine the interface design with these particular necessities: 1) Show textual content within the middle 40% of the terminal display screen, 2) Scale back default studying pace for higher comprehension, 3) Create a static management interface that does not refresh, with solely the studying textual content updating dynamically, 4) Keep clear borders across the lively show space. May you implement these modifications whereas preserving all current performance?”

This resulted within the following terminal management:

def _get_display_area(self):
    """Get the 40% middle rectangle dimensions"""
    cols, rows = self._get_terminal_size()
    
    display_width = int(cols * 0.4)
    display_height = int(rows * 0.4)
    
    start_col = (cols - display_width) // 2
    start_row = (rows - display_height) // 2
    
    return start_col, start_row, display_width, display_height

def _draw_static_interface(self):
    """Draw the static interface"""
    # Controls keep mounted, solely phrases change

An Overview of the Technical Specifics

 
Now we have the next within the RSVP pace studying app we’ve constructed.

Threading for Responsive Controls

This technique captures keyboard enter in real-time with out pausing the primary program by switching the terminal to uncooked mode and utilizing non-blocking I/O polling:

def _get_keyboard_input(self):
    """Non-blocking keyboard enter handler"""
    old_settings = termios.tcgetattr(sys.stdin)
    strive:
        tty.setraw(sys.stdin.fileno())
        whereas self.is_running:
            if choose.choose([sys.stdin], [], [], 0.1)[0]:
                # Deal with real-time enter with out blocking

Good Terminal Positioning

This technique positions textual content at precise coordinates on the terminal display screen utilizing ANSI escape sequences, the place the code strikes the cursor to a particular row and column earlier than printing the phrase:

def _display_word(self, phrase):
    # Use ANSI escape codes for exact positioning
    print(f'33[{word_row};{word_start_col}H{large_word}')

Adaptive Speed Control

This dynamically adjusts reading speed based on word length, giving users 20% more time for long words (8+ characters) and 20% less time for short words (under 4 characters) to optimize comprehension:

# Longer words get more display time
word_delay = self.delay
if len(current_word) > 8:
    word_delay *= 1.2
elif len(current_word) 

 
So yeah, you can run the app, and see for yourself how it works.

First, you can make it executable like so. Make sure you can add the shebang line at the top of the script:

$ chmod +x rsvp_reader.py

You can run it like so:

$ ./rsvp_reader.py sample.txt

You can find more details on the README file.

Conclusion

 
Our vibe coding session produced:

• A fully functional terminal-based speed reading app in Python
• Support for variable reading speeds (50-1000+ WPM)
• Real-time controls for pause, navigation, and speed adjustment
• Adaptive display that works on any terminal size
• Clean, distraction-free interface focused on the 40% center area
• Smart word timing based on length and complexity

In 15 minutes, we went from a simple idea to a functional application that someone can actually use.

Ready to try vibe coding yourself? Start with a simple idea, describe it in plain English, and see where the conversation takes you. The code will follow.
