设计备忘录 — 限流重写

好的杂志编辑过去会把读者从作者的自我沉溺里保护出来。他们砍掉那些看起来聪明但没赚到任何东西的文字。Web 时代这种纪律消失了, 现在大部分长文读起来像第一版穿上了礼服。剩下的好出版物, 是那些仍然让编辑和作者争论的 —— 有时编辑赢。

How CastReader Handles Plain Text

No formatting? No problem

Paste or Upload

Either Works

CastReader's upload tool accepts both a .txt file drop and a direct paste. Copy a few paragraphs from anywhere — an email, a note, a chat — and paste. Or drag in a longer .txt file. Same result: instant audio.

Log Files Supported

Read Logs Out Loud

Server logs, debug traces, CSV data exports — CastReader handles them. Structured data (timestamps, IDs, error codes) reads character-by-character by default, but you can switch to 'summary mode' where CastReader glosses over repetitive rows.

Log file handling

No Structure Needed

Just Text — No Headings Required

Unlike DOCX or MD, plain .txt has no structural markup. CastReader reads it as flat text, using natural sentence breaks (periods, line breaks, paragraph gaps) to pace the speech. You don't need to pre-format anything.

Flat text handling

Auto Language Detection

40+ Languages, Detected Automatically

CastReader reads the first few hundred characters to detect the language, then picks a native voice. Works for English, Chinese, Spanish, Portuguese, French, German, Japanese, Korean, Arabic, Hindi — 40+ languages total. Mixed-language text switches voices paragraph by paragraph.

Frequently Asked Questions

Everything you need to know about turning plain text into audio

What's the difference between TXT to Audio and Free Text-to-Speech?

The /free-text-to-speech page is a browser-based tool where you paste and play. TXT to Audio is file-oriented — drop a .txt file or paste longer text, get an audio output you can download as MP3. Use whichever fits your workflow.

Is there a character limit?

Practical limit is around 500,000 characters per request — roughly a 200-page book's worth of text. CastReader streams audio while processing so you start listening quickly even on long texts.

Can I use it for log files and CSV data?

Yes. Drop your .log or .csv file, CastReader reads it as flat text. For repetitive log formats (e.g. Apache access logs), switch to 'summary mode' in the player to get high-level patterns read rather than every line.

Does it handle special characters and emoji?

Emoji are skipped by default (reading them aloud is rarely useful). Special characters like bullet points (•), dashes (—), and quotes are handled naturally — they affect pacing but aren't pronounced.

Can I download the audio?

Yes. After processing, the audio can be downloaded as MP3 for offline use. File stays yours; CastReader doesn't keep a copy.

Does it keep my text?

No. Your input is processed to generate audio, then discarded. No storage, no training, no retention.

Is it free?

Completely free. No API key, no usage limits, no account required.

Drop Your Text

Completely free. No signup. Upload a .txt or paste text to get audio instantly.
