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 section below on when Sight Reading Factory is the better fit, so you can check the answer against your own situation.
If that question already settles it for you, the placement check finds your grade in about three minutes, with no account.
Which one is built for solo learners?
The core difference in one line
Sight Reading Factory generates an endless stream of exercises for you to read and grade yourself. SightReader generates them too — and then listens to your MIDI keyboard and marks each note in real time, pitch always, timing against the beat once the metronome is on. It does the same for four thousand real published pieces graded ABRSM 1–8.
That is the comparison in one line: most tools make you choose between endless generated material and real graded repertoire, and neither of them hears you play. SightReader is the one that does all three.
What does Sight Reading Factory do well?
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 — the one that most often settles it — instrument. It covers a long list of them, plus voice. SightReader is piano only. If you teach a mixed class, or you play anything that isn’t a keyboard, you can stop reading here: that is the answer.
It needs no hardware at all, which matters if you don’t own a MIDI keyboard. And for a teacher pulling up a fresh exercise on demand mid-lesson, fifteen years of polish on that exact workflow shows. Endless material is no longer the thing that separates the two — but the breadth, the no-hardware start and the lesson workflow still are.
Is Sight Reading Factory any good without a teacher?
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.
We used to argue a second point here — that generated exercises read as statistical rather than musical — and it would be convenient to keep making it. We can’t, because we generate them now, and the honest version is more useful anyway: generated music reads as filler when it’s assembled note by note against a rule, and reads as composed when it’s built the way music is. Ours comes out of the same machinery as our graded courses — a two-bar motif that returns and gets transposed, real cadences rather than always landing on the tonic, antecedent-and-consequent phrasing over eight bars. That’s what makes an exercise feel like a piece someone wrote rather than a legal sequence of notes, and it’s a fair thing to judge either tool on.
The difference that remains is the free tier: Sight Reading Factory has a limited “sight-read for free” demo and a 30-day trial, then a subscription.
Side by side
| App | Fresh generated exercises | Marks the generated exercise | Independent rhythm scoring | Real repertoire, ABRSM 1–8 | Instruments | Free tier | Price |
|---|---|---|---|---|---|---|---|
| Sight Reading Factory | ✓ | Self-assessed | Self-assessed | ✗ | Many | Trial only | $34.99/yr |
| SightReader | ✓ | ✓ | ✓ | ✓ | Piano | ✓ | £5/mo |
Two notes on that table, both against us. The instruments row is the one to read first if you don’t play piano — it isn’t close, and no amount of marking makes up for a tool that doesn’t cover your instrument. And Sight Reading Factory’s own difficulty levels are perfectly good, they’re just not mapped to the ABRSM grades, so that row reflects labelling rather than quality. On price, an individual subscription at $34.99 a year is inexpensive, roughly level with SightReader’s £48 annual plan; SightReader’s cost advantage is the free tier, where the core practice loop costs nothing.
You can check the top three rows for yourself without paying or signing up: the free tier includes generated exercises every day, 54 real pieces, and the full scoring with rhythm included.
How does SightReader work instead?
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. Exercises writes you a new one on demand at whichever grade you pick, in the key and time signature you choose, and marks it exactly as it marks a real piece. 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: piano only, 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.
Does either follow the ABRSM syllabus?
For ABRSM exams
This is where a lot of readers land, and it used to be a genuine split: Sight Reading Factory drilled the exam-day format — a short passage, thirty seconds to look, then play — while SightReader built the fluency underneath from a grade-aligned library. Plenty of candidates ran both. SightReader now does both halves: Exercises generates fresh short passages to each grade’s own parameters, and the library supplies the reading mileage behind them, all marked as you play. The Grades pages spell out what each level expects.
When Sight Reading Factory is the better choice
Choose it if:
- You don’t play piano. This is the big one. Sight Reading Factory covers a long list of instruments and voice; SightReader is piano only. Nothing else on this page outweighs that.
- You don’t have a MIDI keyboard and won’t get one. SightReader’s marking needs one. There’s an on-screen piano for trying it out, but reading practice at a real instrument is the point, and if that instrument can’t talk to the app, the feedback simply isn’t there for you.
- You’re a teacher running exercises live in lessons. Fifteen years of polish on that exact workflow is hard to walk away from, and if a teacher is checking the playing, the missing feedback stops mattering.
So which should you choose?
The verdict
If you play piano and practise alone, choose SightReader: you get the endless generated exercises either way, and only one of the two tells you whether you actually read them. The free tier means it costs nothing to find out. If you play another instrument, or you have no MIDI keyboard, or a teacher already checks your reading in the lesson, 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 — on generated exercises and real pieces alike, 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?
Both generate unlimited sight-reading exercises. The difference is what happens once you play one: Sight Reading Factory puts the exercise on screen and leaves you to grade yourself, while SightReader listens to your MIDI keyboard and marks your reading note by note — pitch always, timing against the beat once the metronome is on. SightReader also has 4,000+ real published pieces graded ABRSM 1–8, and marks those the same way. 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. Sight Reading Factory is good at rehearsing the exam-day format — a short passage, a brief look, then play — because it produces fresh short exercises endlessly. SightReader generates those too, built to each ABRSM grade’s own parameters, and adds the fluency underneath: 4,000+ real graded pieces at your level, with every note marked as you play. Candidates used to need a generator for the format and a real-piece reader for the fluency. That is no longer two tools.
