Love the focus on a local-first approach... being able to improve writing across any app without sending data to the cloud is a huge win. The updates in v2 sound really thoughtful, especially for people who write all day. Excited to keep following where this goes!

Love the concept! Is there a free plan to try it out or how does pricing work? Would love to test it properly before committing.

Congratulations on the launch! A small but convenient app. By the way, I wonder, don’t AI browsers allow this?

this is incredibly cool!! been using typeboost for a while and am consistently impressed!

Benny has been working on TypeBoost for such a long time, and it shows. Highly polished and works great. Happy that this launch is doing well. :)

This looks interesting.

The real friction with AI isn’t the model quality anymore, it’s workflow breakage. The constant context switching, rewriting prompts, and losing flow between apps is what kills productivity.

What I like about this approach is the “your rules, your prompts” angle. That turns AI from a generic assistant into something more like a personal writing OS.

The granular accept/reject edits is also underrated. Transparency builds trust, especially when AI touches your actual words.

Congrats on shipping this. Native workflow tools > browser tab juggling every time.

Will definitely give it a try!

Quick question on privacy. I work with some sensitive client stuff and I'd want to know where my text goes when it's processed. Is anything stored on your end or does it just pass through?

Cool product, as someone who built an AI CMS for a blog recently I really see the benefit of not having to switch focus while writing :)

Congrats on the launch! I've been using ChatGPT for most of my writing but honestly this looks awesome. Not needing to switch to ChatGPT for every little thing is great. Can I get started quickly or does it take some time to set things up?

Hey there, happy launch day!

What's been the biggest technical hurdle in making it work reliably across any app (e.g., permissions, text selection in sandboxed apps, or shortcuts/hotkeys conflicts)? And how do you make onboarding feel instant without overwhelming new users?

Also, have you seen users combining voice dictation with text selection for hybrid workflows (like dictating into emails/docs then refining selected parts)?

this looks amazing 🙌
super clean and easy to use :)

been following your journey on twitter... really excited to see this live :)

Building “AI inside any app” usually means heavy OS permissions and lots of edge cases—what tradeoffs did you make to keep it seamless while still earning user trust, and where did you draw the line on what the app will never access or do?

Hey Benedikt,

Tried the app out today , really cool - i just wish it also had transcription like wispr flow

both the editing and transcription today will really increase the stickness of the product

Congrats on the launch! 🔥

Time to get rid of pains on writing elegantly! Btw, how does it differ from those generic embedded AI writing helper in gmail etc?

Love the value proposition and how you make the toolkit usable from anywhere. Solid UX work. A clear agentic replacement to Grammarly. Quality++

Been using this tool for a while. One thing I can say. The UI is superior for me. I love the simplicity and ease of use. That's it. All I need in a good tool.

Congratulations on your launch 🤝 @bennyqp But for teams, is there a way to share prompt toolkits (e.g. brand voice packs) across members? This would be sooo nice for founders and operators who live in email, Notion, Slack, etc. I’m a content strategist, so if you’re planning to position Typeboost beyond PH, I’d be curious how you’re framing it as a productivity tool.

Great stuff. I am interested in trying this over the next weeks and see my prompting efficiency increasing. But one question: are follow-up prompts possible? Or is a user limited to the prior saved prompts to execute? thanks
