Speech to Math for Voice Typing 🧮
Turn on Math Mode in voice typing and speak equations the way you read them — Helperbird converts your speech into proper math notation. Say "x squared plus three y" and get x² + 3y. Say "alpha equals pi r squared" and get α = πr². Math Mode covers a huge vocabulary across math, physics, and chemistry, including Greek letters, fractions, integrals, derivatives, exponents, and chemical formulas. Just open the voice typing options menu and toggle it on — a small π badge shows when it's active so you always know your dictation is being mathified. Works in the popup and in the PDF reader.

A Better Dictionary 📓
The dictionary lookup page got a major refresh. Tap the speaker button next to any word — or any example sentence — to hear it read aloud in your chosen TTS voice. Perfect for ESL learners, dyslexic readers, and anyone unsure how to pronounce a tricky word. Pronunciation guides (the /ˈbætmən/ format) now appear under the headword when available, and there's a new Opposite words section alongside Similar words. The page remembers your recent lookups so you can revisit them with a single tap, and each search now updates the URL — meaning browser back, forward, and reload all just work. Press / from anywhere on the page to jump straight to the search box, and look up phrases like "ice cream" — the old single-word-only restriction has been lifted. The Wikipedia link in the corner finally takes you somewhere useful too.

More Natural Voices for Text to Speech 🌍
Pro users get a fresh batch of Azure Neural voices for popular regional languages — Spanish (Mexico), Brazilian Portuguese, Mandarin Chinese, Japanese, Korean, Hindi, and French (both Metropolitan and Canadian). Pick voices like Dalia, Jorge, Francisca, Antônio, Xiaoxiao, Yunxi, Nanami, Keita, Sun-Hi, InJoon, Swara, Madhur, Henri, Sylvie, or Antoine for warmer, more natural-sounding playback in your preferred language and region.

Highlights & Notes Without Storage Limits 💾
If you save a lot of highlights or sticky notes, you may have noticed Chrome's sync storage filling up and silently dropping data. Helperbird now splits large saves into chunks behind the scenes, so you can keep as many highlights and notes as you need. If sync ever does fill up, your data automatically falls back to local storage and stays accessible. Existing highlights and notes upgrade automatically on first load — nothing for you to do.

Cleaner Voice Typing Menu ✨
The voice typing options menu has been tidied up. Math Mode sits at the top of the dropdown with a clear on/off check, and Listen, Copy, Clear, and Print are grouped below — only active once you've dictated something. The mic button in the PDF reader now shows the Math Mode indicator too, so the same setting follows you between the popup and PDFs.
Bug Fixes
- Fix
Reliable Notes Backup & Restore 📦
Fixed an issue where exporting just your annotations could produce an empty file, and importing older Helperbird backups could be silently ignored. Backup and restore now work cleanly across versions — your data is portable again.
- Fix
Smoother UI on Big Saves 🪟
When writing large amounts of highlights or notes, the popup used to refresh several times in a row. Helperbird now consolidates those into a single update, so the interface stays steady while your changes are saved.
- Fix
Missing Translation Labels Fixed 🌐
Added 22 missing translation keys for screen reader labels and UI text across the extension — including floating button settings, feature toggles (magnifier, alt text, image titles, word spotlight, hide images, hide GIFs, text stroke, cursor size, highlight links), volume controls, voice group labels, reading level selector, and settings page headings. These labels were showing as blank for assistive technology users.
- Fix
Subscription Data Parsing Fixed 🔐
Fixed an issue where the update banner could fail to read your subscription details, showing a parsing error in the console. The update page now correctly reads encrypted subscription data introduced in an earlier release.
