See Exactly Which Letters Become Digits
This tool applies a small deterministic character map. The result is a visual spelling variant for labels and puzzles; it is not hacking, encryption, or a way to hide a secret.

Six Outputs from the Current Character Map
Every pair below is produced by the same local function used by the page. Letter case does not change which mapped letters are replaced.

Non-Latin characters retained beside a mapped letter
Two Reference Tables for the Implemented Map
| Input | Output | Case Handling |
|---|---|---|
| A / E | 4 / 3 | Uppercase or lowercase |
| I / O | 1 / 0 | Uppercase or lowercase |
| S / T | 5 / 7 | Uppercase or lowercase |
| B / G | 8 / 6 | Uppercase or lowercase |
Complete Replacement Table
These are the only Latin letters changed by the current function.
Pass-Through and Control Behavior
Use this table to predict what the page will and will not change.
| Input Feature | Current Result | Boundary |
|---|---|---|
| Unmapped letter | Unchanged | No word-level rules |
| Punctuation or spacing | Unchanged | Positions retained |
| Existing digit | Unchanged | Cannot reverse uniquely |
| More than 500 characters | Rejected by UI | No output run |
Four Rules for Reading the Result
Eight Letters Have Replacements
The complete table is A → 4, E → 3, I → 1, O → 0, S → 5, T → 7, B → 8, and G → 6. Uppercase and lowercase forms use the same digit.
Everything Else Passes Through
All other characters remain unchanged, including spaces, line breaks, punctuation, existing digits, emoji, and letters outside the eight-entry map.
The Direction Arrow Does Not Decode
Reverse direction runs the same substitution and does not decode digits back to letters. A digit such as 5 could have been typed originally, so automatic reversal would be ambiguous.
Visual Substitution Is Not Secrecy
The output is not encryption and does not hide its meaning from a reader who recognizes the mapping. Do not use it to protect passwords, personal records, or access codes.
What Happens in the Browser
These details describe the current Hacker Text conversion branch rather than making a site-wide network claim.
Local Non-Null Result
The current conversion branch runs in the browser. Input is not sent to the external translation provider because convertLocalToolText returns a non-null string first. This is a narrow code-path fact, not a general privacy policy.
No Translation Meter
The local path does not require sign-in or translation credit because it never reaches the account-metered translation request.
Visible 500-Character Limit
The browser stops the action when input exceeds 500 characters. Because each replacement is one character, successful output has the same JavaScript string length.
Shared Controls, One Transform
The direction arrow can swap the panels, but both directions call the same substitution. Copy reads the output panel, and reset clears the input and output.

Follow the Actual Local Conversion Path
The conversion is a character-for-character substitution rather than a generated language response.
Step 1: Enter a Bounded String
The UniversalTranslatorTool browser form accepts no more than 500 characters and rejects an empty or whitespace-only submission.
Step 2: Run the Local Function
UniversalTranslatorTool calls convertLocalToolText with the hacker-text-generator slug. Its non-null local result is displayed and returns before the external translation provider branch.
Step 3: Copy or Clear the Result
Copy uses the displayed output, while reset clears both panels and restores the default direction. Keep the original if you will need its exact letter case later.
Test One Short String Against the Mapping Table
Enter text, compare each replaced character with the complete map, and keep the original when letter case matters.
