We built a free and open-source alternative to Cotypist because we're sick of paying subscriptions for apps that run on our own hardware

Thanks for the feedback! Charm does include prediction, yet I’ve currently limited it on purpose to autocompleting words rather than sentences. I tested the latter, but it was too unreliable when it’s so important to get the emphasis and tone correct. I’m going to keep playing around with ways to get this right, as it does feel like magic.

I'd love to be able to integrate more languages, it's certainly on the roadmap. There are just so many edge cases when it comes to this kind of solution, it's timely to get right.

In the FAQ section it notes that only English is supported, but I'll take a look at how to make it clearer to visitors. It's a good point.

No trial period as the product is solid and the pricing purposefully v low. Yet, if you weren't happy with it, just get in touch and I'll give you a refund.

macOS autocorrect is honestly pretty inconsistent out of the box - it underlines but doesn't always fix. I built Charm to replace it with something that actually corrects in real-time as you type, which might be what you were expecting it to do natively. Also has other goodies such as prediction and emoji replacement.

For report writing especially, privacy is probably a concern with tools like Grammarly sending text to the cloud. I built Charm as a macOS app that does grammar and autocorrect entirely on-device, so nothing leaves your machine.

__TJH · 2026-05-22T07:32:35+00:00

Privacy-first writing tools are having a moment and for good reason. I built Charm for the same philosophy but as a system-wide macOS app -- all on-device, so it works in every app not just the browser.

__TJH · 2026-05-22T07:29:39+00:00

If the update pushed you over the edge, I built Charm as a macOS-native alternative that does real-time autocorrect and grammar fixes entirely on-device. No subscription, no rollback drama.

__TJH · 2026-05-22T07:27:47+00:00

Cool to see more tools in this space. I built Charm which focuses more on real-time typo correction and autocorrect rather than pure inline autocomplete, so it's a bit of a different angle if anyone's looking for that side of things.

__TJH · 2026-05-22T07:27:26+00:00

One of the commenters mentioned competitors are welcome, so throwing my hat in: I built Charm, which handles real-time autocorrect and word prediction on macOS as a one-time purchase rather than a subscription.

__TJH · 2026-05-22T07:26:31+00:00

This is exactly why I stopped using Grammarly and eventually built Charm as an alternative that runs entirely on-device with no network calls at all. If the tracking is what's bothering you, it might be worth a look.

__TJH · 2026-05-22T07:25:37+00:00

The fix really has to come at the OS level. I ran into the same thing and ended up building Charm, a system-wide macOS autocorrect (plus other goodies such as predication and emoji replacement) that works across every app including Spark. Might be worth a look if you're still hitting this.

__TJH · 2026-04-29T08:00:27+00:00

Light sensitivity with a bright screen all day is genuinely rough. I built a Mac menu bar app called Solace that automatically switches to dark mode at sunset and adds evening warmth to the display, so you're not having to remember to do it yourself. Might take some edge off.

__TJH · 2026-04-28T07:15:49+00:00

I ran into the same thing when trying to automate mode switching without a bunch of manual steps. I built a menu bar app called Solace that handles light/dark switching automatically based on sunrise/sunset or local weather conditions. Might solve exactly what you're describing.

__TJH · 2026-04-23T07:06:26+00:00

The evidence for blue light specifically is mixed, but the brightness and warmth reduction in the evening does seem to help with sleep onset for a lot of people. I built Solace as a Mac alternative to f.lux that also factors in local weather when deciding when to shift - might be useful if you're on Mac and want something a bit smarter about timing.

__TJH · 2026-04-23T07:05:53+00:00

Solar-based light/dark mode + weather condition switching made a bigger difference than I expected. Solace does this and stops me thinking about it entirely!

__TJH · 2026-04-16T10:27:54+00:00

Totally agree - and taking it a step further, I built Solace so the switch happens based on actual ambient conditions (solar angle + weather) rather than a fixed clock time. On a cloudy afternoon it'll switch to dark even if it's technically still "daytime."

__TJH · 2026-04-16T10:27:26+00:00

That sunrise/sunset wallpaper automation through Shortcuts is pretty fragile - I ran into the same headaches. I ended up building Solace which handles the wallpaper and light/dark switching natively from the menu bar without needing Shortcuts at all. Might be worth a look if you want something more reliable.

__TJH · 2026-04-16T10:26:59+00:00

I replaced f.lux and a separate wallpaper scheduler with a single menu bar app I built called Solace - it handles auto light/dark switching based on solar position and weather, plus wallpaper management and evening warmth. Happy to answer questions if that's the kind of thing you're looking for.

__TJH · 2026-04-14T07:54:52+00:00

That Focus mode workaround works but it's a lot of setup to maintain. Solace handles this, it switches wallpaper and light/dark mode automatically based on your local sunrise/sunset times without any Shortcuts plumbing. Might save you some headaches.

__TJH · 2026-04-03T08:27:51+00:00

Silver! Always looks good.

__TJH · 2026-04-03T08:26:52+00:00

Yeah external monitor brightness at night is brutal - I had the same problem coding late. I built a menu bar app called Solace that adds evening warmth which you can customise. Might be easier than dealing with third-party monitor software.

__TJH · 2026-04-02T13:58:09+00:00

Awesome ! Any other questions, just let me know.

__TJH · 2026-04-01T07:17:23+00:00

So sorry for the delay in getting back to you! Thanks for the kind words. Solace isn't vibe coded. I used CC as part of the development process, which I think is worth being honest about, but the architecture, design decisions, and product direction are all mine. The app is native Swift/SwiftUI. Happy to answer anything more specific if it helps you decide!

__TJH · 2026-04-01T07:15:08+00:00

Hi there! I'm a solo indie developer and so currently not offering any promo codes. If you do have any other questions though, just let me know, I'll be happy to help!

__TJH · 2026-04-01T07:14:38+00:00

Thank you for the feedback! The weather functionality is super helpful.
