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

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 on Smart Typewriter and Traveler.

In software, the common wisdom is that a rewrite is almost never the answer. 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 — 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:

🏃 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:

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

Beta Tester Mark L.

🔋 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 “new” + “pg 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.

The winning short story in the 2026 Freewrite 500 is "Deathbed Victory" by Rocky Halpern.

I wish my mother could be a little less enthusiastic about losing weight from chemotherapy. Her sharp wrists and angular neck are trophies others remark upon. They look past her hair and eyebrows that are like hay carried away by a thunderstorm and ask if she’s doing keto or mediterranean. 

The world is mesmerized by shrinking things. Mini candy bars, happy meal toys, tiny dogs that fit inside a purse, dollhouses, adults who weigh as much as children. 

My mother wants me to go on Ozempic. I sit next to her hospital bed, and she wraps her wisp of a hand around my thick, pulsing wrist. She asks me to dream of wearing matching bikinis on the shores of a tropical beach. She wants me to share in her religion, recite the sacred text: Nothing tastes as good as skinny feels. 

But chemo has rubbed her tastebuds down to a dull throb, so what does she know about it anyway? 

She dozes off as evening begins to creep. The TV mounted to the wall across from the bed plays a muted rerun of Friends, the one where Monica wears a fatsuit. She is half my size, at least. I turn off the TV, let go of my mother’s hand, and head toward the cafeteria. 

I examine limp premade salads, gray tuna fish sandwiches, and an unmanned make-your-own smoothie station. Eating dinner here doesn’t leave me with much of an appetite. Maybe I don’t need weight loss medication after all, I can just skulk the halls and wonder how much time we have left together. 

How much of that time will my mother spend wishing there was less of me? 

How much less of her can there be before she disappears? 

A nurse is checking her vitals when I return to the room. My mother looks at me, laughs softly, and asks the nurse, Can you believe she used to fit inside of me? 

I think of how we must have been, her warm body encasing mine like a bacon-wrapped date. I wonder if she ate hot fudge sundaes when she was pregnant with me. I wonder if there is a single moment of her life where she didn’t feel terrified of her body. 

My mother is a ghost and it’s the proudest she’s ever been, her deathbed victory lap. Somewhere, Jenny Craig sheds a tear and whispers into the ether, It’s not just about losing weight; it's about gaining life.
