Apps like Morse Code Reader turn a phone into a pocket telegraph key: type a message, hear it as dots and dashes, or point the microphone at a real signal and read it back as text. We took that same core idea and built Pulse Code, a free translator that runs right here in your browser. Type in either direction, listen to the beeps, watch the light flash, and try a daily decode round when you want to test what you have learned.

Type into either box and the other updates as you go. Press Play to hear and see the message in Morse.
How to use it
The translator has two boxes: plain text and Morse code. Type a word into either one and the other fills in live, no button needed. Hit Play and Pulse Code beeps out the dots and dashes through your speaker while a light flashes in sync, muted by default until you tap the sound toggle. A speed slider sets the pace from 8 to 30 words per minute, and both your last message and your chosen speed stay saved in your browser.
Switch to the Daily challenge tab for the return-hook half of the tool. We play a random word in Morse, beeps and flashes together, and you type what you heard or saw before the 60-second round runs out. Everyone gets the same set of words on a given day, so a run today is a fair comparison with a friend trying the same round. Your best score and your day streak are saved on this device only, nothing leaves your browser.
How it compares to Morse Code Reader
Morse Code Reader does considerably more than a browser translator ever could. It listens through the phone’s microphone to decode real Morse tapped out by another person, reads flashlight signals through the camera, supports custom keying speeds and tone frequencies, and keeps working entirely offline with no browser tab required. It is built for people who actually use Morse: ham radio operators, scouts practicing signaling, or anyone learning the code for real-world use.
Pulse Code keeps the part that makes typing in Morse fun in the first place: watch a word turn into dots and dashes instantly, hear it played back, and try to decode it cold in the daily challenge. We left out live microphone listening, camera flashlight decoding, and any offline installer. There is no history beyond your best score and streak, and no custom tone or keying hardware support.
If you want to quickly check what a word looks like in Morse, or warm up your ear before a scouting exam, this covers it well. If you need to actually receive and send real Morse signals, whether by radio, flashlight, or tapping, the full app is the tool built for that job.

Frequently asked questions
Can I read Morse code online without downloading anything?
Yes. Pulse Code runs entirely in the browser tab you are looking at right now. Type text or Morse into either box and the translation happens instantly, no app, no account, no plugin.
Is this the real Morse Code Reader?
No. Pulse Code is an original translator we built, inspired by the type-and-listen idea behind Morse Code Reader. We are not affiliated with, endorsed by, or connected to jfedor or Morse Code Reader in any way. For live microphone and flashlight decoding, download the official app using the link above.
Does it work offline?
Yes, once the page has loaded. Pulse Code is a single file with no outside requests, so the translator and the daily challenge both keep working even if your connection drops. Your saved message, speed setting, best score, and streak all live in your browser’s local storage on your device only.
Is the daily challenge the same for everyone?
Yes, on any given day. The word order is generated from the date itself, so a player in Nairobi and a player in Lisbon hear the same sequence of words that day. Restarting during the same day reuses that day’s words, so your retries stay a fair comparison against your own best.
Is it free?
Yes. There is no signup, no paywall, and no ads between you and the translator. Everything runs client-side, so nothing about your message is sent anywhere.
