Picosteno Picosteno

A full Steno kit from Nolltronics. Starting at $20 for the PCBs and mounting hardware and going up to $61 for everything you need, this is the cheapest board you can make!

Stenokey Stenokey

Stenokey is an open-source do-it-yourself stenographic keyboard project. It is aimed at makers with some electronics experience (soldering) and who own a 3D printer or who have a friend with a 3D printer.

The Uni v2 PCB The Uni v2 PCB

The Uni v2 PCB, instructions in the description. Some prior experience is recommended. Only comes with a PCB and has pre-soldered diodes.

Yet Another Steno Keyboard YASK

YASK is an easy-to-build open-source design for a steno keyboard. Simple, no 3D printing needed, also exists in angled & staggered version. Check out the build instructions

Out-of-production Machines

Models that are no longer made or available for sale.

Product Name Manufacturer About Years
Stenoboard Utopen (Emanuele Caruso) Stenoboard

The Stenoboard was the first open source steno machine on the market, released in 2014 for around $180USD. The Stenoboard’s keys actuate like mouse-clicks instead of a keyboard or lever-machine, which made it very uncomfortable to use.

2014-2017
SOFT/HRUF Scott Urueta Original SOFT/HRUF

The nonsplit version of SOFT/HRUF.

2017-2018, superseded by the Splitography
Stenomod Charley Shattuck Stenomod

Open source hardware. This has light (35g actuation) keys and a split design. See Ted Morin’s review of the Stenomod as well as Martin Körner’s review. The name is supposed to hint at how the machine is “modular” and adaptable.

2017-2018, superseded by the TinyMod
Georgi g Heavy Industries Georgi

Portable, affordable, and light-touch option. Low-profile Kailh Choc switches with 12g-actuation springs swapped in makes this the lightest-touch and lowest-height machine made for Plover so far. The removal of a number bar reduces costs and weight for portability. A third thumb key is to be used as a number bar replacement like the TinyMod. See Martin’s Georgi Stand with Trackball review, Mirabai’s review, Aerick’s Georgi Mount, and Josh’s photos.

2019-2021
Steko Quanic Boards Quanic Boards Steko

A simple, small steno keyboard featuring a RP2040 chip, a USB-C interface, Durock Dolphin silent switches, and 3D Printed PLA keycaps.

2022-2023

Stenotype Machines

Supported protocols

Plover supports several protocols that are in use by various machines:

  • Stentura serial: most machines by Stenograph and many others.
  • Gemini PR serial: typically any recent machine made by the Neutrino Group, such as the Piper, Revolution, or Infinity series.
  • ProCAT: protocol used by all ProCAT machines.
  • TX Bolt: an older protocol supported by some machines as a primary or secondary protocol.
  • Treal: used only by the Treal from Word Technologies.
  • Passport: used only by the Passport Writer from Advantage Software.

This means that, in theory, many machines work with Plover.

Known supported stenotypes

The following machines have been confirmed by users to work with Plover after actually trying it:

Keyboards

If you don’t have a steno machine, you can use a keyboard that supports N-Key Rollover (NKRO).

What’s NKRO?

NKRO stands for N-Key Rollover. This is a feature of some keyboards that means that you can press as many keys as you want simultaniously, and they will all register. Typical keyboards stop working correctly when you press somewhere between 4 and 7 keys at once. For more information, see the Wikipedia entry about NKRO.

How do I know if my keyboard has NKRO

In general, most keyboards will not be NKRO. “Gaming” and mechanical keyboards are most likely to have NKRO, while budget as well as laptop keyboards are unlikely to have NKRO.

The easiest way to test for NKRO is to visit https://keyboardchecker.com/ and press several keys all at once to see if they register. If your keyboard has NKRO, you will be able to press multiple keys with your palm and they will all light up as green on the website. If your keyboard does not have NKRO, several keys will not light up on the website.

What if my keyboard is not capable of NKRO?

If you don’t have a keyboard that’s capable of NKRO, but still want to give Plover a try, you can arpeggiate/roll the keyboard chords. Have a look at the Beginner’s Guide for more information.

Known supported keyboards

You can search for NKRO keyboards compatible with Plover by including “NKRO” or “anti-ghosting” in your search query. Make sure to check reviews before purchasing as some have been known to falsely advertise NKRO (although, this is a rare occurrence).

Which type of key switch should I choose?

Due to how multiple keys must be pressed simultaneously, there are two properties that are useful to have in a mechanical keyboard switch for steno: a light actuation force on a linear switch.

The light actuation makes it easier on your hands. For a chord like TKPWHRAOEUGD (gliding), you are hitting 8 keys with your left hand. That means that whatever switch force you need to depress one key, you have to push 8-times as much. For a 80cN (~80 grams, ~2.9 oz) switch, that’s 640cN (~640g, ~22.6 oz). For this reason, your wrists will have a much easier time working with your machine if its actuation force is as light as possible.

How many keys are in the average chord?
1: 23
2: 221
3: 1115
4: 3247
5: 6168
6: 7820
7: 7293
8: 5069
9: 2707
10: 1126
11: 331
12: 90
13: 21
14: 3
15: 1

The linearity is recommended because it’s been found that the tactile feedback that one gets from an individual switch is not as useful when you are receiving 4-10 of those feedbacks at once. The brain just doesn’t process all the fingers’ feedback in a useful manner. And since the bump usually requires a small addition to the actuation force, we recommend keeping it linear and simple.

Professional steno machines, historically, always bottomed out (meaning the keys are pressed until they can no longer travel; the bottom.) Newer machines use more complicated mechanisms for detecting key travel, often using magnets and the hall effect to determine where the key is, allowing for customizable actuation points. The typical force required for a modern steno machine is between 10cN and 20cN, with some extremes on either end for personal preference. The travel of a typical lever steno machine is usually between 2mm and 30mm. The lower end is found in machines like the LightSpeed (nonlever), where the higher end is around the maximum that you can configure a lever machine to stroke.

Most of the mechanical switches have a 2mm actuation point and 4mm travel/bottoming out, but some community members have found that “speed switches” with an earlier actuation point (usually 1.1-1.4mm) are better for steno due to their increased sensitivity.

Switch Stat Note Machines
Kailh Choc Pink Pro 20 cN linear The lightest stock option available, though the reduced travel distance makes it feel comparatively heavier All Nolltronics boards use this switch
Gateron Clear / White 35 cN linear A popular stock option available on the market Stenomod uses this switch
Matias Red 35 cN linear Feels heavier than 35 cN switches due to having a “flat” force curve. Matias also has a different stem from Cherry SOFT/HRUF uses this switch
Cherry MX Red 45 cN linear
Kailh Silver 50 cN spring* linear Has an early actuation (1.1mm vs 2mm)
Cherry MX Brown 45 cN bumpy While not ideal compared to other options, this switch is still a better choice than blues, blacks, and other Cherry switches
Kailh Choc Red 50 cN spring* linear The Georgi uses this switch
  • The Kailh silvers and Choc reds use a spring that would cause a 50 cN actuation point at 2mm, but since they actuate earlier (1.1mm), the force required is nearer to 35 cN.

There are other methods to decrease actuation force for even these switches. This includes:

  • Putting SPRiT 15g Choc springs into the Kailh Choc Pink Pro
  • Putting the Gateron Clear’s 35 cN spring into the Kailh Silver for its earlier actuation point.
  • Trimming the springs of a linear switch by several mm to reduce force.
  • Using an aftermarket spring with lower forces, such as a prototype 20 cN spring that isn’t yet released to the wider market.
  • Removing the leaf-spring (not the primary spring) in the Matias Red switch to make the force curve less flat.

Adapt a keyboard for steno use

Most keyboards have the keys in staggered rows, which can make it difficult to press two keys in a column with a single finger. To adapt a keyboard for steno use, you can use:

  • Keytoppers
  • Keycaps

You can also use a keyboard with an ortholinear layout.

Keytoppers

Laser-cut keytoppers are in the shape of the keys on a steno machine. You stick them on top of the relevant keys on the keyboard. You can buy laser-cut keytoppers from the Plover Store. You can also make your own keytoppers out of plastic or even coins.

Keycaps

If you have a mechanical keyboard, it is likely your keys have a Cherry MX stem and will work with custom keycaps. You can replace the existing keycaps on your keyboard with different keycaps, to improve the layout for stenoing.

  • StenoToppers is a 3D printed keycap set designed by Jason Cemra. It aligns the rows, raises the keys, and reduces the keycap tapering, slant and gap. The 3d model (.stl) files are available on Github. If you have access to a 3D printer, you can download .stl files and print them for a negligible cost. Otherwise, you would need to use a 3D printing service.

  • The G20 keycap set from Signature Plastics is a great set for steno, and will fit on an ErgoDox or other mechanical keyboard. The keys have a direction, so for optimal comfort, you should angle the top row of steno (STPH...) down, so that they are close to the bottom row (SKWR...)

  • You can 3D-print a steno-friendly keycap.

Keys that have little space between them are good for steno, because then you can hit two neighboring keys with one finger (which is frequently necessary).

NKRO keyboards with an ortholinear layout

Keyboards with an “ortholinear” layout have the keys in straight columns. This is handy for steno, as it makes it easier to press two keys in a column with a single finger.

The following machines have been confirmed by users to work with Plover after actually trying it:

Product Name Manufacturer Protocol/Connection Comments
ErgoDox ErgodoxEZ, Massdrop, FalbaTech, others USB The ErgoDox is a fairly high-end NKRO keyboard at $200, with an ortholinear layout. It has two separate halves, so you can angle them to suit you. You can order it with the Gateron White keys, which have an extremely light, 35 gram activation force. Read a guide to Starting Stenography with an Ergodox by Paul Fioravanti.
Planck OLKB USB The Planck is a fully programmable NKRO keyboard with an ortholinear layout. It is 40% the size of a standard keyboard. Read a guide to starting stenography with a Planck by DiDoesDigital.
Preonic OLKB USB The Preonic is a fully programmable NKRO keyboard with an ortholinear layout. It is 50% the size of a standard keyboard.
Gherkin USB The Gherkin is a fully programmable NKRO keyboard with an ortholinear layout. It is 30% the size of a standard keyboard.
Iris Keebio USB The Iris is a cheaper and slightly smaller alternative to the ErgoDox. It is a fully programmable split NKRO keyboard with 56 keys. The firmware needs to be edited to enable either NKRO or Gemini PR. Available in PCB and pre-built.

Laptops with NKRO

If you want to always have steno on the go, you might consider finding a notebook with NKRO. Note that not all these machines are equivalent in terms of actuation force or key shape. You might find, for example, that chiclet keys don’t feel as good as the Alienware’s classic keyboard style. It’s always best to try laptop keyboards at a local store, if possible.

*: Untested for use with Plover

Laptops that don’t actually work with Plover

After testing some of the laptops on the list above, they were found to not live up to their claims.

Model Manufacturer Claimed Rollover Findings
HP Omen 15 and 17 HP “26-key rollover anti-ghosting” Combination “YUHJ” on Qwerty only produces 3 letters
GF62 and GP72 MSI “anti-ghosting for up to 45 keys” 99% of chords were OK, certain combinations wouldn’t work – e.g. QWEAS blocked R. Keyboard also responded abnormally slow when writing chords.

Video Game Controller

It is possible to use a video game controller with Plover by installing the Plover Controller plugin. Please use the built-in Plover plugins manager to install this plugin. This is one of the cheapest options to get you started! If you don't have a USB or bluetooth controller lying around, you can find a used one very cheap, and you can even buy new ones for a great price.

Note: as per the project's README, there may be issues using it with macOS.

Troubleshooting

Most issues can be resolved by following the mapping instructions for the Plover Controller plugin.

Usage

The diagram below shows where all of the corresponding keys are located. This layout closely resembles the standard Ward Stone Ireland stenography layout, so it can be used with a standard theory, like Plover theory or Lapwing theory.

The diagram also shows how stick movements that move in the opposite direction of steno order will skip the keys in-between. For example, to to write a word starting with "th", such as the word, "this," you would want to select T- and H- without the P- in-between. Moving the left stick clockwise from T- to H- would output TPH-, which is not what we want. To get the output of TH-, you would move counter-clockwise from H- to T-. However, reverse steno order does not always mean counter-clockwise. Another example is the word WHA -> "what,". To output WH- , you would want to move clockwise from H- to W-
