We Conquered the Lag: The Freewrite Firmware that Transforms Typing on E Ink

November 19, 2025 | 3 min read

Introducing the Freewrite firmware that makes typing on E Ink as smooth and fast as thinking.

It's named after the fastest fish in the ocean for a reason.

Write at the Speed of Your Thoughts

Sailfish is a full top-to-bottom rewrite of the software that runs onΒ Smart Typewriter and Traveler.

In software, the common wisdom is that a rewrite is almost never the answer.Β Turns out that sometimes, it’s the only option.

In 2015, we started the Freewrite journey by creating a distraction-free writing environment using a brand new technology (at the time) that allowed us to use standard web development languages (i.e. JavaScript). We picked an architecture that made sense for us at the time, choosing speed of development over performance.

Well, startup life isn’t easy, and we stayed on that software architecture a lot longer than any of us expected. We did many optimizations over the years but none could match the performance of a native application.

So, we decided to burn it all down and rebuild.

It was the only way to move forward with the advanced features we dream about creating. But doing a full rewrite was a big project! (Kind of like rewriting your novel from page one. 😰)

The software needed to work on two similar but unique hardware platforms, and it needed to provide the same core Freewrite experience β€” but vastly improved. We also didn’t want to launch missing any features.

It took a full year of daily effort from the entire Freewrite team, especially our small team of firmware developers, to rewrite the platform. (Which we did in Rust, for you software nerds out there.)

The result is better than we could have hoped for:

πŸƒ Latency is virtually gone.

Sailfish is 40% to 100% faster from key press to a character showing on the display.

In practical terms, that means it takes about half the time for a character to appear.

Or, as one beta tester put it:

β€œThe new firmware makes typing laptop fast. […] Hard to believe it's still E Ink.”

Beta Tester Mark L.

πŸ”‹ Battery life is dramatically improved.

While typing, power consumption is 30% less. While idle, power consumption is up to 50% less!

Yes, all from a pure software update.

This means dramatically improved battery life in all situations AND dramatically improved performance.

"I have to admit, I’m astonished by the improvement.”

Beta Tester Michael J.

⏱️ Every single operation is faster.

Waking, sleeping, changing drafts, navigating, it is all done without a hiccup.

Switching between drafts is a lot faster, as well as using the β€œnew” + β€œpg up/down” features. Now you can move throughout your drafts at the speed of thought.

Booting up is faster, too, even with the addition of a brand-new animation by artist Mathias Lynge designed to help you center yourself before your writing journey begins and celebrate what this update means for Freewriters.

"I've always been told that E Ink couldn't give instant responses without lag, and now with this update I can finally tell people that's not true."

Beta Tester Will B.

This firmware is more than an update. It's a modern foundation for the future.

This is a brand-new starting point for the Freewrite family. It will enable us to build upon it in brand new ways and continue improving the Freewrite experience ecosystem beyond what has previously been possible.

We're super proud of this monumental effort by the team and can't wait for you to experience it on your own Freewrite Traveler or Smart Typewriter.

Don't take our word for it. Download 3.0 today.

The best part is that all of this new performance is 100% free to you and will be available via over-the-air update for:

  • All Traveler models, including Ghost
  • Smart Typewriter Gen 3 (including Ink, Lemon, and Mint)
  • Hemingwrite Gen 3
  • Valentine

Note: Alpha uses a different screen and software base. The performance on Alpha’s LCD panel is already optimized.

Firmware rolls out automatically and will be available on your device when connected to Wi-Fi. You can also manually check for an update using these instructions:

P.S. With every firmware update, we also add another classic author to the screensaver lineup. Last time, it was Agatha Christie. Who can name the new writer this time around?

We’re all just dreaming the impossible dream every time we face the keyboard!

P.S.S. Love the new bootup animation? Read all about the animator, Mathias Lynge, here.

A new year means a whole new crop of work is entering the public domain. And that means endless opportunities for retellings, spoofs, adaptations, and fan fiction.

It’s Freewrite’s favorite time of year. When dictionaries around the world examine language use of the previous year and select a β€œWord of the Year.”

Of course, there are many different dictionaries in use in the English language, and they all have different ideas about what word was the most influential or saw the most growth in the previous year. They individually review new slang and culturally relevant vocabulary, examine spikes or dips in usage, and pour over internet trend data.

Let’s see what some of the biggest dictionaries decided for 2025. And read to the end for a chance to submit your own Word of the Year β€” and win a Freewrite gift card.

[SUBMIT YOUR WORD OF THE YEAR]


Merriam-Webster: "slop"

Merriam-Webster chose "slop" as its Word of the Year for 2025 to describe "all that stuff dumped on our screens, captured in just four letters."

The dictionary lists "absurd videos, off-kilter advertising images, cheesy propaganda, fake news that looks pretty real, junky AI-written books, 'workslop' reports that waste coworkers’ time … and lots of talking cats" as examples of slop.

The original sense of the word "slop" from the 1700s was β€œsoft mud” and eventually evolved to mean "food waste" and "rubbish." 2025 linked the term to AI, and the rest is history.

Honorable mentions: conclave, gerrymander, touch grass, performative, tariff, 67.

Dictionary.com: "67"

The team at Dictionary.com likes to pick a word that serves as β€œa linguistic time capsule, reflecting social trends and global events that defined the year.”

For 2025, they decided that β€œword” was actually a number. Or two numbers, to be exact.

If you’re an old, like me, and don’t know many school-age children, you may not have heard β€œ67” in use. (Note that this is not β€œsixty-seven,” but β€œsix, seven.”)

Dictionary.com claims the origin of β€œ67” is a song called β€œDoot Doot (6 7)” by Skrilla, quickly made infamous by viral TikTok videos, most notably featuring a child who will for the rest of his life be known as the β€œ6-7 Kid.” But according to my nine-year-old cousin, the origins of something so mystical can’t ever truly be known.

(My third grade expert also demonstrated the accompanying signature hand gesture, where you place both hands palms up and alternately move up and down.)

And if you happen to find yourself in a fourth-grade classroom, watch your mouth, because there’s a good chance this term has been banned for the teacher’s sanity.

Annoyed yet? Don’t be. As Dictionary.com points out, 6-7 is a rather delightful example at how fast language can develop as a new generation joins the conversation.

Dictionary.com honorable mentions: agentic, aura farming, broligarchy, clanker, Gen Z stare, kiss cam, overtourism, tariff, tradwife.

Oxford Dictionary: "rage bait"

With input from more than 30,000 users and expert analysis, Oxford Dictionary chose "rage bait" for their word of the year.

Specifically, the dictionary pointed to 2025’s news cycle, online manipulation tactics, and growing awareness of where we spend our time and attention online.

While closely paralleling its etymological cousin "clickbait," rage bait more specifically denotes content that evokes anger, discord, or polarization.

Oxford's experts report that use of the term has tripled in the last 12 months.

Oxford Dictionary's honorable mentions:aura farming, biohack.

Cambridge Dictionary: "parasocial"

The Cambridge Dictionary examined a sustained trend of increased searches to choose "parasocial" as its Word of the Year.

Believe it or not, this term was coined by sociologists in 1956, combining β€œsocial” with the Greek-derived prefix para-, which in this case means β€œsimilar to or parallel to, but separate from.”

But interest in and use of the term exploded this year, finally moving from a mainly academic context to the mainstream.

Cambridge Dictionary's honorable mentions: slop, delulu, skibidi, tradwife

Freewrite: TBD
