Lernstift: The Fountain Pen With Built-In Spell-Check (VIDEO)

15/07/2013 08:15 | Updated 13 September 2013

The rise of spell check has probably been a net-gain for humanity - despite the best-efforts of evil Auto-Correct filters.

But while near-ubiquitous spell check means your emails are more legible than ever - and ensure that you're less likely to misspell ubiquitous - when it comes to writing in ink, you're still pretty much on your own.

Until now. Two German fathers have invented the world's first fountain pen with built-in spell check.

The digital device watches what you write and emits a subtle vibration when it thinks you've made an error. Aimed at school children and teachers, the idea is to help bring the benefits of digital writing to traditional paper-and-ink - and to help stop the decline of cursive.


The inventors of Lernstift are looking for £120,000 in funding on Kickstarter to help bring the pen to the mass market. So far they've raised £16,000, and have about a month to go in their campaign. The team explains:

"Current digital pens use optical sensors to pick up the writing movements and digitalize the words or sketches for computer use. Some of them require external devices. Others only work with specialty paper.

Lernstift is different. It requires none of those. It's the first truly intelligent pen because all the tech and software is built-in. It can be used with apps but it doesn't depend on them."

The current prototype uses a Linux computer built into the casing of the pen, run off a single AAA battery. It contains a specially-designed motion sensor to help track the path of your writing, and accurately know when you've made a mistake - either in spelling, or the shape of your handwriting. It works in English and German. And unlike existing 'Smart Pens', like Anoto's Livescribe, it doesn't require special paper either. The next models will be smaller, more reliable and we hope built to withstand the frustrations of constantly harassed handwriting students.

If you're intrigued, head over to Kickstarter for more details on the pen and to read the full business plan for the device. A pledge of £99 will get you one of the pens when they eventually hit the production line.

  • 1 Apple iPhone 6s
    The iPhone 6s on the surface at least looks like your bog standard update. Visually it's very much the same animal but look a little deeper and this is an entirely different phone. There's now a pressure-sensitive display utilising a feature called 'Force Touch' while a blistering new processor means it's one of the most capable gaming devices outside of your living room.
  • 2 Google Nexus 5X
    The Nexus 5X strikes the ultimate balance between power and affordability. Taking over the responsibility from the frankly excellent Nexus 5, Google's new smartphone boast an ultra-light body but still crams in a fingerprint sensor, the latest version of Android marshmallow and a Full-HD display.
  • 3 HTC One A9
    The HTC One A9 is the iPhone for people who love Android. There's simply no denying the design similarities between the two phones. Thankfully HTC's packed this with more flagship features than you can shake a indecently sized stick at. There's a fingerprint reader, 5-inch Full-HD display, 13MP camera and the A9 can play high-resolution audio.
  • 4 Sony Xperia Z5 Premium
    Sony has created the world's first truly 4K smartphone. While you might be wondering why, the fact is they've gone ahead and done it anyway. Utilising Sony's amazing screen expertise it should come as no surprise to learn the display is an absolute stunner. There's a fingerprint reader and the ability to play high-res audio.
  • 5 Google Nexus 6P
    The Google Nexus 6P is Google's answer to the big-screen phone. Sporting a 5.7-inch Full-HD panel, the 6P has a beautifully thin unibody enclosure while the subtle fingerprint scanner on the back can be used for security and for paying. You'll also get the added advantage of owning a phone that'll always get Google's Android software before anyone else keeping it safer than ever.
  • 6 LG G4
    The LG G4 is LG's most advanced smartphone yet. Combining a massive 5.5-inch 2K display with a powerful F1.8 lens camera this is a phone that means business. If you can get past the size of it then you'll be richly rewarded. Thanks to that F1.8 lens LG claims that the G4 is the closest you'll get to a professional SLR on a smartphone without spending thousands on a camera.
  • The Galaxy S6 Edge is probably the most advanced phone available right now. With it's stunningly curved 2K display and powerful octa-core processor this is a return to form for Samsung that was much needed. If you're after the absolute cutting-edge then this is for you, just don't expect the battery to last any longer than a day.
  • The Moto X 2 is significant for two reasons; the first of which is that you can almost entirely design it yourself. On top of that you get a stunning 5.2-inch display that's matched with a phone that measures in at just 3.8mm at its thinnest point. Thanks to Motorola's agreement with Google it's pure Android and will get updates from Google as soon as they're announced. For now, this is your Nexus replacement.
  • This is the Samsung Galaxy Note 4 and it shows the biggest departure from Samsung's design thinking yet. Gone is the cheap plasticky body, replaced with a thin metal frame and smooth leather back. The screen is still 5.7-inches but Samsung's upped the resolution to a massive 2K.
  • The Nokia Lumia 930 is the flagship phone for Microsoft. Running the increasingly impressive Windows Phone operating system the 930 is a serious contender against the iPhone 6 and S6. It also happens to be a seriously powerful smartphone as well with a 5-inch Full-HD display, 20MP camera and professional levels of film recording thanks to four mics for full stereo pickup.
