Show HN: Refine – A Local Alternative to Grammarly

https://refine.sh
122•runjuu•4h ago

Comments

gbalduzzi•3h ago
Does this only supports English?
runjuu•3h ago
Theoretically, it could support over 140 languages, as it is powered by the newly released Gemma 3n model. However, I haven’t tested many languages yet.

In upcoming releases, Refine will support custom prompts and BYOK (Bring Your Own Key), allowing you to use any large language model you want.

pyman•1h ago
What's the rationale behind adding BYOK? Or the advantages?

You do realise you're already using an optimised model built for everyday devices, and that model includes some serious innovations in parameter-efficient processing, right?

You're a great developer, and it looks like you're thinking about adding features like BYOK quickly to please more users. But in doing that, you might be missing the real innovation you've already created. You've basically built a version of Grammarly without the privacy issues that make most IT departments ban it.

No one wants Grammarly or your tool sending corporate emails or documents to a language model.

Look at Apple. Privacy is what sets them apart. And right now, privacy is your biggest feature.

Use that. Add a big table to your site comparing your products privacy with Grammarly's. That's your strongest selling point, and probably the only feature that can truly compete with the big players.

My advice? Keep improving the app, but keep the model local. Keep it private. That's the killer feature you've got.

planb•3h ago
Seams weird to not have "How does this compare to Apple Intelligence Writing Tools" at least in the FAQ. Maybe refine is better or has more features, but the page doesn't even seem to acknowledge that a system level feature like this exists.
Nicell•2h ago
Neat idea. I see why the fluency feature is off by default. It constantly rewords things, adds random quotations, or does something pretty silly https://imgur.com/oVSWmtN

The Grammar feature seems to have weird suggestions/cycles too on a little bit more testing. Curious to see how this improves. A local only, one-time-purchase grammarly alternative is appealing!

mirrormaster•2h ago
Isn't privacy a concern? How do consumers ensure that data is not going to captured in a future update without it being open source or having third party security audits?
awestroke•2h ago
That's a concern with all apps ever so idk what answer you're expecting
mananaysiempre•2h ago
Except the open-source ones, or sandboxed[1] ones without any auto-update functionality (not sure if this app has any).

[1] Loosely; I’d say not referencing any networking entrypoints or dlsym() also counts, as working around that would be very non-deniably malicious.

Deukhoofd•2h ago
Does anyone know how this compares to other products in its field, such as LanguageTool and Harper? LanguageTool can be hosted locally, and Harper runs entirely as an extension, so I'm interested in how the spelling and grammar checks compare.
boramalper•1h ago
+1. Also worth noting that both LanguageTool [0] and Harper [1] are FOSS.

raegis•34m ago
I just tested both on the text "Look Dick. See Jane. Jane run home. I says you go home to. They eats dinner." LanguageTool does what I would expect. Harper does not. However, both whine about two spaces after a period.

Edit: Alas, Hacker News also removes the extra space after periods.

codesnik•14m ago
browser rendering does. You'd need white-space: pre-wrap rule to retain double spaces.
smartmic•2h ago
Worth to mention as another alternative: Harper[0]

patrakov•2h ago
Harper is so basic that I can't recommend it.

Does not catch a singular/plural discrepancy between the subject and the verb in a sentence--a common mistake when the expressed thought applies equally to one thing or to many things.

Does not catch a missed indefinite article--a common mistake for speakers of languages that don't have articles. Similarly, does not catch the use of the indefinite article for a thing already mentioned before.

Does not even catch the obvious "don;t" typo.

InsideOutSanta•2h ago
This is precisely what I've been hoping somebody would build. In my initial testing, it works well. I can even mix sentences with different languages, and it still makes correct suggestions.

The fluency suggestions are seemingly largely malfunctioning. It frequently suggests starting and ending sentences with quotes, although it also makes some useful suggestions. There seems to be an issue with analysis running synchronized, or something like that; when I type into a text field and Refine starts to run, it often blocks text entry. Selecting a suggested replacement blocks the app for half a second or so. Neither of these problems occurs with Grammarly or Language Tool. I also noticed a bunch of issues that Grammarly catches (like verb agreement) that Refine does not.

But this is an amazing first release and extremely promising. Congrats!

why is there no open source alternatives to this? Seems ripe to be just built.

What I'd be interested in would be something I could host on my local server (e.g. with ollama) to get suggestions on my laptop, where I write typst or markdown with Zed or VSCode.

I realize I'm a niche :)

Does anybody know of such a tool?

Yeri•1h ago
I'm missing some information on how this works (a LLM? which? Do I need to bring an API key? Does this work offline?) and what I can expect in terms of performance/battery hit.
parkcedar•1h ago
> Lightning Fast. Local processing means instant results without internet dependency or delays. > Always Available. Works offline, on flights, in coffee shops, anywhere you write.

Two of your 4 questions were answered in the first content block

zipping1549•1h ago
Considering that it mentions offline capability I'd say local tiny LLM.
d3m0t3p•1h ago
It is Gemma 3n, I can't give feedback yet on the battery hit, But I would not expect anything bad as these models have been developed for much smaller devices (Phones)

Inviz•1h ago
Couldnt make it to show suggestions in vscode/cursor. I would like to use the tool, but i'd expect it to work consistently across all widgets in the system (i.e. like superwhisper). Is there a technical limitation here or my misconfiguration of things?
cjs_ac•1h ago
The screenshot shows the (corrected) example sentence:

> Sometimes I still make mistakes with articles and prepositions, but my grammar is getting better every day I practice.

In American/Simplified English, this is grammatically correct. However, in 'full fat' English, practice is a noun, whereas practise is a verb; e.g.:

> I go to my practice to practise medicine.

The problem I have with this website is that it's entirely concerned with peripheral issues. The product respects my privacy - good. The product is performant - good. The product doesn't require an Internet connection - good. The product works in many writing apps - good. The product has transparent pricing - good. But I don't give a shit about any of this until you convince me that this will consistently do the correct thing, and this website singularly fails to achieve this.

tossandthrow•1h ago
I get this.

> ... in 'full fat' English ...

English is a bastard of a language and getting messier every day as new nations adopt it is their standard language.

Setting the bar where it is well written and unambiguously understandable is IMHO completely fine for a 15$ product.

Having a text spell checked to comply with contemporary Oxford English is likely not the goal of this product.

cjs_ac•1h ago
> English is a bastard of a language and getting messier every day as new nations adopt it is their standard language.

I disagree strenuously with this idea, because it suggests that there is one 'big' English in which anything goes. A better idea is the one of the register[0]: there are many Englishes, many sets of rules. Different rules are used in different regions, by different groups of people, and have different connotations (e.g., the King James Bible was intentionally written in a form of English that was considered archaic at the time because that would make it sound more grandiose).

If I were to use this tool, I'd be using it to ensure that whatever I'm writing is well-received by my intended audience. Because English usage is so varied, I would need to be able to control the register that it uses to ensure that the output is suitable. The fact that the product website doesn't even mention a list of supported languages, let alone supported dialects and registers within those languages, has a very everyone can see what a horse is kind of feeling[1].

You still need to adapt it to where you are though, people expect this because it causes misunderstandings. If I as a British person go to the US, I know that I can't ask people to go and buy some booze from the off-license and when finished ask them to put their aluminium can in the bin ready for the rubbish lorry while wearing their jumper because that sounds anachronistic.
Normal_gaussian•52m ago
Lets be fair here, this tool is new - the domain was registered on Saturday.

What you suggest does seem like a good early doors feature; but the cut they've made seems to be the right one to prove market potential.

cjs_ac•48m ago
It's fine if the tool has severe limitations at this stage. However, it's crucial to clearly state what those limitations are: not only does it prevent the flurry of complaints and chargebacks from customers who were disappointed that their specific case is unsupported, but it's also an opportunity to introduce a 'we're on this journey together' aspect that helps to make customers emotionally invested in the product.
adastra22•6m ago
So you’re saying that for most English speakers it was correct, and that’s a problem?

I worry that this will make my writing more likely to fail an AI coursework detector, which could really impact my life. The risk just isn't worth it till someone has tested the output through all the big players (turnitin etc.)

If you are running local LLMs what is the hardware requirement in my machine? Don't see any mention of that.
smcleod•1h ago
How well does it handle standard international English? So many of the tools I've seen seem to only support American English.
Andrew_nenakhov•38m ago
Speaking of which, isn't it time to consider American English to be the standard one?

Colour and licence are so quaint.

smcleod•33m ago
Well, only Americans use it. There's no point in arguing about it your version of a language is better or worse but for the rest of the world it's incredibly annoying having to correct Zs with Ss when using LLMs or American only software.
Andrew_nenakhov•27m ago
I'm actually Russian. The whole world uses American English, by virtue of US dominance in all important technical and cultural spheres.
smcleod•17m ago
"The only whole world uses American English" ... I think you might be living in a bubble. It sticks out like a sore thumb.
richrichardsson•26m ago
I could care less about this attempt at trolling, but I won't.

We have enough American cultural hegemony as it is. It frustrates me no end that I regularly am unable[1] to configure software to use my preferred version of English.

[1] or it's extremely difficult. CLion I'm looking at you; every available option I have is set to British English, but still you insist on telling me my Colours should be corrected to Color etc. :(

adastra22•3m ago
English is a bastard language of French and Saxon. But we don’t get upset over that because Britain made the world English. Now the USA is making the world American. That ship has sailed.
jasekt•1h ago
Wonderful! I've given it a go, works in Apple's Notes app, but it does not seem to trigger suggestions in Chrome, Firefox or Slack. It does however highlight misspellings there. Any idea what can I do to enable suggestions there? I was looking for a product like this.

You can use a local instance of LanguageTool in a docker container for this:

nusl•28m ago
I've installed it to give it a try but it does absolutely nothing in any application I use. I did give it required permissions.
throwaway915•17m ago
You should create a bulk license for academic institutions.

And think global. A lot of private schools around the world require students to use Macs so no software update. Have a British English option for outside North/South America as, aside from some edge cases, British English is more common at a school level.
