Localize, translate or correctThree modes: make a story feel local to another country, translate any language into any language (names and culture kept), or only fix spelling, grammar and punctuation.

Long novels, nothing lostUp to 120,000 words. Every line keeps its meaning, emotion and place; each part is checked, and a long job can be continued later.

Script from any linkPaste a YouTube video or Short and its captions become a clean, punctuated script; web pages, online stories, Google Docs and subtitle files work too. Then check the plan, polish, compare and redo any paragraph.

How to use AI Story Localizer

Paste your script, open a TXT, Word, PDF or subtitle (SRT/VTT) file – or paste a YouTube video, web page or Google Doc link and press Get the script.
Choose what should happen – Localize, Translate or Correct mistakes – and the language of the result. Mistakes in spelling, grammar and punctuation are fixed automatically in every mode.
Read the result, compare it with the original, redo any paragraph, then download TXT or Word, split it for voiceover tools or make a YouTube title and description.

Three ways to use it

🌍 Localize – the story moves to another country: new names, places, customs and situations, written like a local author.
🔤 Translate – any language into any language: English to Urdu, Urdu to English, Hindi to Arabic, Korean to Spanish… Names, places and culture stay as they are, and each name is spelled the same way every time. Idioms are translated by meaning, not word for word.
✍ Correct mistakes – the same language, only fixed: spelling, grammar, punctuation, spacing and typing mistakes, without changing your words or style.

Your script can be written in any language – it is detected automatically. The result can be in the national languages of countries around the world – Urdu, Roman Urdu (Urdu in English letters), English (US or UK), Arabic, Hindi, Bengali, Persian, Turkish, Spanish, French, German, Russian, Chinese, Japanese, Korean and many more – or type any other language. With Fix spelling, grammar and punctuation mistakes automatically switched on, mistakes in the original are never copied: the result uses correct punctuation for its language, for example ، ۔ and ؟ in Urdu.

What it changes

The AI first reads your whole script and plans the change: every character gets a realistic name for the new country, places become real local places, and customs, food, clothes, celebrations, money, jobs, schools and ways of speaking are replaced with their local equivalents. Situations that would not happen in the new country are turned into realistic local ones with the same emotional stakes – for example a forced marriage between families can become a contract marriage to save a family business, or a strict condition in a wealthy grandfather’s will.

Then it rewrites the script part by part, line by line, in the same order. The plot, emotions, dialogue and length stay true to the original.

Made for creators

YouTube story channels and voiceover artists.
Writers adapting their own books for readers in another country.
Businesses adapting ads, product pages and social posts for a new market.

Please only adapt your own writing or content you have permission to use.

Made for long scripts

Novels and long YouTube scripts of up to 120,000 words are read in sections; every new character and place found later is added to the same plan, so names stay consistent from the first page to the last. If the AI gets busy or you close the page, press Continue where it stopped – finished parts are kept on your device.

Tools for a professional result

Check the plan first – see every original name, place, custom and situation next to its new local version and change anything before the rewrite starts.
Editor polish pass – a second AI “editor” reads the localized script again and makes the wording, idioms and dialogue sound fully native.
Compare view – original and localized paragraphs side by side; press ↻ on any paragraph to write it again, optionally with your own request (more emotional, simpler, more formal…).
Rename everywhere – change a name in the whole result in one step.
Parts for voiceover tools – split the script into parts that fit the character limit of your text-to-speech tool, copy each part or download them all.
YouTube pack – five title ideas, an opening hook, a description with hashtags, thumbnail text and tags in the language of your video.

Get the script from a YouTube video or any link

No script? Paste the link instead. For a YouTube video, Short or live replay the tool reads the video’s own captions – in any language the video has – and turns them into readable paragraphs. Automatic captions usually have no full stops or commas, so you can let the AI fix punctuation and make paragraphs first, in the original language, before anything is localized. Sound tags like [Music] and ♪ are removed for you.

YouTube – videos, Shorts and live replays that have captions; choose the caption language when there are several.
Web pages and online stories – only the main story or article text is taken, without menus, adverts and comments.
Google Docs – shared with “Anyone with the link”.
Pastebin, Dropbox and Google Drive links to TXT, SRT or VTT files.

A story in several videos or pages? Get part 1, then add part 2, part 3… to the end of the same script. If YouTube does not let our server read a video’s captions, open the video, press …more → Show transcript, copy the transcript and paste it – the tool cleans it the same way.

Please localize only videos and stories you made yourself or have permission to use. Re-uploading someone else’s story, even in another language or country, can bring a copyright claim on YouTube.

Frequently asked questions

Can I translate from any language into any language?

Yes. Choose “Translate”, then the language of the result. The original language is detected automatically, so English to Urdu, Urdu to English, Urdu to Roman Urdu, Hindi to Arabic and every other pair works. Long novels are translated part by part with the same name spellings throughout.

Does it correct spelling and punctuation mistakes?

Yes. “Fix spelling, grammar and punctuation mistakes automatically” is on by default in every mode. If you only want your text corrected, without translating or changing it, choose “Correct mistakes”.

Can I get the script from a YouTube video?

Yes. Paste the video link and press “Get the script”. The video’s captions are turned into a script with paragraphs, and the AI can add punctuation first. The video must have captions (most do, at least automatic ones). Private, members-only and age-restricted videos cannot be read.

YouTube says it cannot read the captions – what now?

Sometimes YouTube limits automatic requests. Open the video on YouTube, press “…more” under it, then “Show transcript”, select the transcript text, copy it and paste it into the box. Or download the subtitles as SRT or VTT and open the file.

Which other links work?

Public web pages, blogs and online story pages, Google Docs shared with “Anyone with the link”, Pastebin, and links to TXT, SRT or VTT files on Dropbox or Google Drive. Pages that show the text only after you sign in cannot be read – copy and paste the text instead.

Is it free?

Yes. You only need a free account. A fair daily allowance per account keeps the AI available for everyone – long novels can be finished over more than one day with Continue.

How long can my script be?

Up to about 120,000 words. A 5,000-word story usually takes a few minutes; a full novel can take an hour or more, and you can stop and continue at any time.

Will it shorten my story?

No. Every line is rewritten in its place and each part is checked; if a line is missing, the part is done again. The new script is about as long as the original.

Can I choose the new names myself?

Yes. Keep “Let me check and change the new names” switched on – after the plan is made you can edit every new name, place and equivalent, and the whole script uses exactly your choices.

What does the polish pass do?

A second pass by an AI editor improves the flow, idioms and dialogue so nothing sounds translated, without changing events or shortening anything. It takes about twice as long.

Can I keep the original names or religious references?

Yes. In Advanced settings choose “Keep the original names” and “Keep exactly as in the original” for religion. You can also list words that must never change.

Which languages can the result be in?

The national languages of about 70 countries – Urdu, Roman Urdu, English, Arabic, Hindi, Bengali, Persian, Turkish, Spanish, French, German, Russian, Korean, Japanese, Chinese and more – and you can type any other language. Urdu and Arabic are shown right-to-left and the Word file uses a Nastaliq font.

Can I use the result for YouTube voiceovers?

Yes – choose “YouTube story script for a voiceover” and clean paragraphs. Use “Parts for voiceover tools” to split it for your text-to-speech tool and “YouTube pack” for the title and description. Please only adapt your own writing or content you have permission to use.

Is my script private?

The script is sent through our server to Google Gemini to be rewritten and is not stored on our server. Your text and progress are kept only in your own browser.

How do I connect my own free Gemini key?

Open “🔑 Connect my own free Gemini key” just below the tool. Go to aistudio.google.com/apikey, sign in with your Google account, press Create API key, copy the key, paste it in the box and press Save, then Test my key. It is free and needs no card. The key is kept only on your device. Full step-by-step guide.

Why do I need an account?

This tool uses AI or online services that cost us money to run. A free account (name and e-mail, confirmed with a short code) keeps it fair for everyone. Most of our other tools work without an account.
