How it works

1

Paste or speak your text

Enter the text you want to translate. You can also use voice input directly from your device's microphone.

2

Review each sentence

BirdSing splits your text into sentences and shows multiple AI-generated variants — standard, formal, concise — for each one. Tap the best fit for each sentence.

3

Confirm & edit & copy

Once you've selected a candidate for each sentence, hit Confirm. The full translation appears in an editable area — make any final tweaks, then copy with one tap.

* Proofread mode follows the same flow — just select the Proofread tab at the top instead of Translate.

Frequently asked questions

Is BirdSing free to use?
Yes, completely free. No account, no sign-up, no credit card required.
How is BirdSing different from Google Translate or DeepL?
Most translation tools give you one result per block of text. BirdSing splits your text into sentences, generates multiple tone variants for each, and lets you review and approve them individually before assembling the final translation. You stay in control of every sentence.
What AI model does it use?
BirdSing uses Claude Haiku by Anthropic — a fast, accurate model well-suited for natural-sounding translation.
Is my text stored or shared?
Your text is sent to the AI model for translation only. We do not store your content on our servers.
Can I use it on my smartphone?
Yes. BirdSing is designed mobile-first and works well on both iOS and Android in any modern browser. No app installation required.
What is Proofread mode?
In Proofread mode, you enter text in one language and BirdSing suggests corrections and improvements in the same language — great for polishing drafts before translating or publishing.
Do I need to install anything?
No installation needed. BirdSing runs entirely in your web browser.
Which browsers are supported?
Chrome, Safari, Firefox, and Edge on both desktop and mobile. Text-to-speech and voice input availability depends on your browser and OS.
