A comparison written by one of the two
Letters & Devotion vs Khan Academy
We make one of these, so read this the way you would read any comparison written by a seller. What we can do is be specific about our own product, accurate about the shape of theirs, and honest about where they are the better answer. Their current price is on their site, not on this page, and the reason is at the bottom.
What Khan Academy is
Khan Academy is a non-profit offering free instructional video and practice across a very wide range of subjects, used by tens of millions of people. It is genuinely free, with no advertising, and it is one of the best things on the internet. Any comparison that pretends otherwise is not worth reading.
The pricing difference that actually decides it
Khan Academy is free. There is no subscription, no per-child pricing and nothing to cancel. If cost is the binding constraint in your household, that fact should probably decide this and we would rather say so plainly.
Letters & Devotion is $29 a month for every child in the household, month to month, with no per-child seats and no course limits. That is $348 a year whether you have one child or four, or $290 a year on the annual plan. The first 30 days are free, a card is taken and nothing is charged until day 30, and cancelling before then costs nothing.
The comparison to run is the same either way: monthly price, times the number of children, times twelve.

- Money is the constraint. It is free, permanently, and it is good. Nobody should pay $29 a month they do not have for something they can get a large part of for nothing.
- You want to fill a specific gap. For one shaky topic in algebra or one unit of chemistry, Khan is the better tool and it costs nothing to try this afternoon.
- You are confident building and sequencing the year yourself. If you enjoy assembling a curriculum from parts, Khan plus your own scope and sequence is a legitimate and very cheap way to homeschool.
Where Letters & Devotion is different
A sequenced year, not a library
Letters & Devotion is 84 courses laid out as a scope and sequence: units in order, skills in order, objectives written down. The work of deciding what comes next and whether the year is complete has already been done. That work is exactly what a free library leaves to you.
Records that satisfy a state, without you writing them
Instructional hours log automatically, mastery is tracked per skill as a portfolio record, and a transcript prints in one click. If your state asks for hours, a portfolio or a transcript, that is the gap a free video library does not fill.
A teacher that answers this child
Clara reads the answer your child actually gave and explains the specific mistake in it, in conversation. Video is the same for everyone who watches it, which is its strength for scale and its limit for one child at a table.
One place, every subject, every child
Every core subject K-12 plus health, PE, art, music, computer science and world languages, for every child in the household, at one price.

Questions parents ask
Can I homeschool with just Khan Academy?
Many families do, particularly for maths. The work it leaves you is sequencing the year, deciding what counts as complete, and keeping whatever records your state requires. If you are willing to do that, it is free and it is good.
Why would I pay when Khan is free?
For the sequence and the records, and for a teacher that responds to your specific child's wrong answer. If those three things are not what you are missing, Khan is the better choice and you should keep your $29.
Does Letters & Devotion have ads or trackers, like a free product might?
No. There is no advertising network, ad pixel or tag manager anywhere on the site or in the product, including the pages children use. Khan Academy is a non-profit and does not run ads either.

Why there is no price for Khan Academy on this page
We checked in September 2026 and the sources contradicted each other, including the companies' own pages against the review sites. Publishing a competitor's price that turns out to be wrong is unfair to them and useless to you, and any figure here would be out of date within a month anyway. Ours is above, because it is ours and we can stand behind it. Theirs is one click away, on their site, where it is current.
