I've had a blog since 2003, and I started writing on Medium in 2015. I've written mostly about public health (my day job), but I also write about my life and the things that interest me. It's been great to grow a community on Medium, and I'm excited about the possibilities of a bigger community on TK, a community of writers. I've been using TK for a few months, and it has kept me writing each day, reading other people’s writing, and thinking about how to better communicate the complex issues I want to write about. TK is simple, but powerful. It really does feel like a notebook with some superpowers that help you write without writing for you.
I love how you described it as a notebook with superpowers, @rene_najera . I totally agree!
It’s become second nature to reach for TK. It started with just some daily journaling, which just by itself was delightful, but I’ve started working in TK because it’s just so smooth for writing and refining. I’ve used the skill and Claude integration to create a social media content machine that searches for idea nuggets, expands them into social media posts or video scripts, then Claude grabs them and drops them into ordinal. I feel a bit like a god? And the content I’m sharing is still mine, and sounds like me.
TK is the cornerstone of my day. It's where I write to clear my head in the morning, where I run my schedule, and where I turn when new ideas come up that I want to get down. I used it last week for a memo about the future of search and for my Saturday shopping list. And I love that I don't have to tag or structure any of my writing, just write once, and it's available for me to explore forever. It's also turned writing from a thing I wish I was doing more of into an actual daily habit. So excited to have it now in the hands of many more people to see what the community does with it.
After searching for years for a comfortable online writing space that feels 'real' in the sense that I can write and ramble the way my brain cobbles together thoughts, impressions, data, poetics, and my everyday chatter, all the while looking up things I've already written about, I'm smitten that TK fills exactly that need.
As a Medium writer, the double benefit of having all my Medium writing linked to TK, and vice versa, just made my day. At last, a keyword search returns solid results pulled from within my writing universe.
Need I even stress that I loooove the daily note feature. I can embrace my daily journaling practice again without pressure, in a space filled with super-talented and productive creatives. TK is my new ecosystem.
Thank you. Medium!
I’ve been using TK daily for about a month, and the community keeps bringing me back. I’ll start reading something wonderful, notice an interesting comment halfway through, and click over to see what that person is writing. Suddenly, an hour has disappeared. It feels like falling down an old-school internet rabbit hole, where one interesting person or idea leads you to another. I’ve really missed that feeling, and it’s been wonderful finding it here.
I've been writing online for years. From blog posts to short stories to personal essays. My workflow has changed a lot. I used to draft on Medium, then moved to Google Docs, then Obsidian for YEARS. All of them solved some aspects, but not all of them. I needed a home for my messy drafts, fully formed thoughts, basic notes, and everything else.
TK is the first app to do it. I journal there, use the scratchpad to take notes, write out proposals, blog posts, book reviews, and just general thoughts. It's the first app to give me everything I need while getting out of my way and letting me write. The community of writers is an amazing bonus
It's hard to thread the needle well when it comes to writing and AI, but the Medium team has done just that with TK. This agentic notebook is agentic in the best way -- it will provide agentic help only when you ask for it. TK gives you the freedom to ideate, explore, and express in a way that reminds me of the original internet when I was a teenager.
But the AI tools are there for you. TK is great when you get stuck or need a push while mid-thought. It's what a true writing assistant should be -- there to assist, not to do the actual writing for you. I haven't come across another space quite like it on the modern internet, which are increasingly filled with LLMs and products that take away what writing is most valuable for, thinking.
There's also a very underrated part of TK that I don't see many discussing and that's community. There's a library functionality that allows users to create a space for likeminded people to gather. For example, I'm a law, politics, economics, and general humanities junkie and I run a publication on Medium called The Political Prism. TK allows us to have a central space to discuss anything going on at the pub or to brainstorm about the topics we write about or to discuss the writing itself. Almost like an old school Internet forum with AI tools!
And the best part? There's no incentive for anyone to post AI slop.
Cheers to putting humans in the driver seat in this AI world. Well done, Medium.
