What is worth examining is how strongly the promise gets stated. The tool below sits at the far end of the same argument.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
A tool that cannot invent anything
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it.

This tool uses text rules, not AI. It cannot invent a fact because it only rearranges words you pasted in, which is also its limit: it covers nothing your notes left out and it cannot tell you that a definition you wrote down is wrong. Grounding at the strongest possible setting, with the honest cost attached. Your text stays in the browser and is never sent anywhere.
| Risk | Removed by grounding | Still on you |
|---|---|---|
| Inventing a fact from nowhere | Largely, yes | Spot checks |
| Summarising a passage wrongly | No | Read the reasoning |
| Answering from a superseded page | No | Check against the final version |
| Repeating an error in your notes | No, it is faithful to them | Fix the source |
| Answering when the answer is absent | Only if it refuses | Test it once, deliberately |
What grounding means in practice
Restricting a model to documents you supply, then requiring answers to come from what was retrieved, is the technique usually called retrieval augmented generation. It works, and it is the correct default for study material: a tool that answers from your lecture notes beats one answering from everything it ever read, because your exam is set on the notes.
Two words for the same promise
Cuflow's home page describes its output as hallucination free in one place and describes its tutor as hallucination resistant in another. Those are different claims and only the second is the kind a system of this shape can support. Grounding changes where the words come from; it does not verify that the retrieved passage answers the question asked, nor that the failure mode disappeared.
Where a grounded tool still goes wrong
Three ways, and none of them require the model to make something up. It can pull the right passage and summarise it in a way that inverts a condition. It can answer from the one page that mentions a term while a later page corrects it. And it inherits every error in your source: if the lecture slide was wrong, the ground truth it is faithful to is wrong too.
Which is why the reasoning has to be visible
The practical defence is not a stronger promise, it is a shorter check. When each answer carries the reasoning that produced it, a wrong one is usually obvious in seconds because the step that fails is written down. That is ordinary checking made cheap enough to actually do, which beats any assurance printed on a marketing page.
What WeSolve+ does with the same principle
It reads the file you give it and writes questions from that, with the reasoning attached to each item so the method can be checked rather than trusted. Missed questions return on later days. It does not claim to be incapable of error, because no tool of this kind is, and a page that told you otherwise would be the first thing on it worth doubting. Free to start on web and iPhone: pricing, features.
How to read any grounding claim
Ask what the tool does when the answer is not in your documents. Refusing is the good behaviour; producing something plausible from general knowledge is the failure, and it is invisible precisely when you needed the tool most. Then ask whether you can see why it answered as it did. Those two questions separate grounded products faster than any adjective on the home page. See AI for students.

Does source grounding stop hallucination?
It reduces it substantially and it is the right architecture. It does not eliminate it, which is why the more careful phrasing on Cuflow's own site, resistant rather than free, is the accurate one.
Is a grounded tool safe to trust without checking?
No. It can summarise a correct passage incorrectly, answer from a page a later page corrects, and reproduce any error your own notes contain.
How do I test a grounded tool in one minute?
Ask it something your documents genuinely do not cover. Refusing is the good answer. A confident, plausible reply built from general knowledge tells you what it will do when it matters.
Does WeSolve+ claim to be error free?
No. It attaches the reasoning to each question so a wrong one is quick to spot, which is a more useful thing than a promise.
Why does the tool on this page use no AI at all?
To show the far end of the trade. It cannot invent anything, and it also covers nothing your notes left out and cannot tell you a definition you wrote down is wrong.
Is grounding worth paying for?
Working from your own material is worth choosing on its own terms, since your exam is set on that material. Judge the specific product on what it does when an answer is missing.
