SightReader and Sight Reading Factory both help you get better at reading music at the keyboard, but they go about it in almost opposite ways, and which one fits you comes down to a single question: does anything check what you actually played?
Full disclosure before we start: we make SightReader. There’s a whole section on when Sight Reading Factory is the better choice, because for a lot of people it is.
If that question already settles it for you, the placement check finds your grade in about three minutes, with no account.
The core difference in one line
Sight Reading Factory generates an endless stream of exercises for you to read and grade yourself. SightReader listens to your MIDI keyboard, follows a real published piece, and marks each note in real time — pitch always, and timing against the beat once the metronome is on. One gives you infinite material and trusts you to assess it; the other reads fewer-but-real pieces and does the assessing for you.
What Sight Reading Factory does well
Sight Reading Factory has been around for over a decade and is well regarded by teachers, especially in the US. It generates an effectively unlimited supply of sight-reading exercises, customisable by key, time signature, difficulty and instrument. You will never run out of material, and for a teacher pulling up a fresh exercise on demand in a lesson, that workflow is hard to beat. It is browser-based, reliable, and if your reading is checked by someone else, its one big limitation simply doesn’t apply to you.
Where it leaves solo learners on their own
The gap that sends people looking is always the same: it can’t hear you. You read a generated exercise on screen and grade yourself. Practising alone, you have no independent check on whether you actually read the passage or quietly smoothed over the bar you fluffed. That’s precisely the habit sight reading is meant to break.
Two smaller differences follow. Sight Reading Factory reads generated exercises rather than real pieces: technically correct, but assembled by a formula, so they tend to read as statistical rather than musical. And there’s no permanent free tier: a limited “sight-read for free” demo and a 30-day trial, then a subscription.
Side by side
| App | Listens as you play (MIDI) | Independent rhythm scoring | Reads real pieces | ABRSM 1–8 graded | Free tier | Price |
|---|---|---|---|---|---|---|
| Sight Reading Factory | ✗ | Self-assessed | ✗ | ✗ | Trial only | $34.99/yr |
| SightReader | ✓ | ✓ | ✓ | ✓ | ✓ | £5/mo |
A note on that table: Sight Reading Factory’s own difficulty levels are perfectly good, they’re just not mapped to the ABRSM grades, so the “ABRSM 1–8” row reflects labelling, not quality. And on price, an individual Sight Reading Factory subscription at $34.99 a year is inexpensive, roughly level with SightReader’s £48 annual plan. SightReader’s cost advantage is the free tier: the core practice loop costs nothing.
You can check the top two rows for yourself without paying or signing up: the free tier includes 54 pieces and the full scoring, rhythm included.
SightReader’s approach
SightReader exists to close the feedback gap above. It listens to your MIDI keyboard, follows the score in real time, and colours each note as you play: green for right, red for wrong, blue or yellow when the metronome is on and a note lands early or late. The cursor keeps moving on purpose: in an exam, or accompanying someone, you can’t stop to fix a bar, so practice shouldn’t let you either.
Since July 2026 that feedback covers timing as its own dimension. Pitch & Rhythm mode scores every note against the beat and reports how much of the piece you played on time, early and late, with your average tendency in milliseconds. Nothing in Sight Reading Factory’s self-assessment model produces an equivalent number, because nothing is listening. Rhythm scoring is new and still being tuned, and it’s on the free tier.
The library is just over four thousand real pieces from the public-domain repertoire, tagged by ABRSM grade from 1 up to advanced Grade 8, so there’s room whether you’re on your first pieces or a strong player after a challenge. Daily practice picks a handful at roughly the right level each day, and there’s a free note-recognition trainer for players still learning the notes and a scales mode alongside. Where it doesn’t win: it needs a MIDI keyboard (a phone-only setup won’t work), the teacher tools are earlier than Sight Reading Factory’s, and it won’t teach theory or replace a teacher.
For ABRSM exams
This is where a lot of readers land, and the two tools do different halves of the job. Sight Reading Factory is good for drilling the exam-day format — a short passage, thirty seconds to look, then play — because it spits out fresh eight-bar snippets endlessly. SightReader builds the fluency underneath, by having you read a grade-aligned library at exactly your level with feedback on every note. Plenty of candidates use both. The Grades pages spell out what each level expects.
When Sight Reading Factory is the better choice
Choose it if:
- A teacher checks your reading. The missing feedback stops mattering, and the endless generated exercises are excellent lesson material.
- You’re a teacher generating for a class. Fifteen years of polish on that exact workflow is hard to walk away from.
- You only want to rehearse the exam format. For short-passage-then-play drilling, an on-demand generator simulates it well.
The verdict
If you practise alone and want something to tell you whether you actually read the notes, choose SightReader: that’s the case the missing-feedback gap hurts most, and the free tier means it costs nothing to find out. If your reading is already checked by a teacher, or you mainly want infinite exercises to drill the exam format, Sight Reading Factory is a fair and well-made tool and you may not need to switch at all.
If you’re weighing up the wider field rather than just these two, the best piano sight-reading apps covers it, and Sight Reading Factory alternatives looks at the other options alongside it. Whichever you pick, the gains come from steady reading over months, so settle on one and use it regularly.
So if you want the opposite of self-assessment — real pieces, and something that tells you what you actually played — that’s the thing SightReader is built to do, and you can test the claim on your own keyboard before deciding.
FAQs
What is the difference between SightReader and Sight Reading Factory?
Sight Reading Factory generates unlimited synthetic exercises for you to read on screen and grade yourself. SightReader listens to your MIDI keyboard, follows real published pieces graded ABRSM 1–8, and marks your reading note by note as you play — pitch always, and timing against the beat once the metronome is on. If you practise alone, the marking is the difference that matters.
Is Sight Reading Factory free?
Not permanently. Sight Reading Factory has a limited “sight-read for free” demo and a 30-day free trial, then it is a paid subscription (individual accounts are $34.99 per year, educator accounts $45 per year). SightReader keeps a permanent free tier — reading real pieces with live MIDI feedback — with a paid plan at £5 a month for the full library and extras.
Which is cheaper, SightReader or Sight Reading Factory?
On the yearly headline price they are close: Sight Reading Factory is $34.99 a year for an individual, and SightReader is £5 a month or £48 a year. The real difference is the free tier — SightReader lets you practise indefinitely for nothing, where Sight Reading Factory only offers a trial. If your budget is zero, SightReader wins; if you want the cheapest paid annual plan, they are in the same ballpark.
Does Sight Reading Factory give you feedback as you play?
No. It generates an exercise for you to read, but it does not listen to your keyboard or tell you which notes you got right — you self-assess. That is fine when a teacher checks your playing and a real gap when you practise alone. SightReader uses a MIDI keyboard to mark your reading note by note as you go, and with the metronome on it scores your timing too.
Which is better for ABRSM exams?
Both help, differently. Sight Reading Factory is good for rehearsing the exam-day format — a short passage, a brief look, then play — because it produces fresh short exercises endlessly. SightReader builds the underlying fluency by having you read a large library mapped to ABRSM grades 1–8 at exactly your level, with feedback. Many candidates use a generator for the format and a real-piece reader for the fluency.
