Hey Product Hunt 👋
I’m Tony, CEO of Medium. TK is our new agentic notebook, built by people who love to write, for a world that now runs on words.
Every AI tool you use gets better the more of your thinking it can read, so every word you write, even the messy ones, works on your behalf.
Chat apps can help you research, but TK helps you write. Three simple steps level up your writing: craft, compound, create.
1. Craft. Writing is thinking.
Craft your best writing distraction free—no clutter and a TK agent that works inline so that you never have take your fingers off the keyboard.
Pull ideas from an instant memory of all your words: voice memos from your walk, partial drafts, Granola notes, Claude research chats, anything you’ve ever written on Medium, and, yes, your old Bear or Obsidian vault.
---
2. Compound. Every note makes the next one more useful.
Deep thinking comes from building on what you’ve written before. The TK agent can remember, prompt next steps, and organize all your writing. You can /wikify anything into a mini knowledge base, transform raw ideas into blog posts, and transform blog posts into books.
The deepest thinking requires feedback, so TK ships with built-in social and agentic feedback loops.
---
3. Create. The more you write, the more influence you have on the world.
Share privately, publish publicly. Turn your ideas file into apps with Claude Code. Pass your written intelligence to any agent you work with.
---
For maximalists, connect your writing to your entire agentic universe and run your entire day from a single Daily Note. Install the TK Claude plugin for this extremist view on fighting brain fry.
Free tier ships with everything other note taking apps charge for: unlimited notes, publishing, and collaboration. Plus built-in agent and social layers.
Pro tier is $12/month for full access to the TK agent, skills, summaries, and MCP.
Onward to more writing!

I wish there were a way to say this that wouldn't sound so cheesy: I remember what it felt like to get my blogger account, and to be able to write about muddy, messy, or even mundane things, and turn strangers into lifelong friends because of words. I remember what it felt like to get my twttr account, and turn strangers into lifelong friends because of words. These past months of the TK beta have felt exactly the same. And, yet again, I feel complete strangers becoming lifelong friends, just because of words.
So, yeah, I 1000% subscribe to the premise underlying this moonshot, and I'm glad you keep going and keep trying and keep believing that writing is thinking, and thinking is important.

I'm one of the engineers on TK, so take this with the appropriate grains of salt, but I joined the team as someone who wrote in brief, sporadic bursts, very occasionally. I admit I was worried about joining Medium, a company built on writing, and the TK team, to build a product to write in, as someone who wasn't a habitual writer.
Building TK, and using it, has made me a fierce believer in writing as a practice. At the most foundational level, writing is a way to think, and writing is also a way to force yourself to think about what you want to write about, even when you're not writing. This is good, and is achievable with a pencil and paper. You can also do it in a bare-bones editor. And you can do some great organization and discovery and search with an editor, and there are great tools to do this.
The thing that's new, of course, is LLMs. LLMs operate on text. Their nature is textual.
Someone (I truly wish I could find who to credit for this) made the metaphor that LLMs are "text elementals." (forgive me, I'm about to nerd out about Dungeons and Dragons, but briefly: "elementals" are magical entities in D&D that have special traits associated with and abilities to manipulate one of the four "elements": earth, air, fire or water) As "text elementals," LLMs exist on the text plane, their home is words and they operate on words and they can do something that feels like magic with words. So when you, as a writer, create words, you're extending the plane on which these text elementals can operate, and they grant you a different kind of power to operate on those words.
Sometimes this is goofy (one of my favorite skills in TK is a "high school alignment chart" that classifies a corpus of writing in the classic nerd/jock | prep/nerd quadrants) and sometimes it's genuinely powerful. We have users writing books, using TK's assistant to help them organize themes and find inconsistencies. I use it to extract themes from essays I write about TK, and to help me organize my thinking about the product itself and how we build it. I have a handful of cron jobs that launch Claude Code and run skills I've built to search for and collect user feedback in TK and share that to a TK library, which is indexed nightly by an llm-wiki skill. Then, I can use the output of those skills, and my own writing, to improve the product, and improve my thinking about the product, and write (like I am here) as a human being about the things the text elementals have discovered for me.
Anyway, this product has been a labor of love for me and -- I think it's safe to say -- everyone on the team, and I hope using it brings you as much joy as it's bringing us to build it.

I didn't "work" on this app in the engineering sense, but I worked on this app in that I've written literally thousands of words in it, shared feedback with the team, watched it turn into something amazing, and (most importantly for me) had space to write out my muddled, messy thinking in a clean, free space until my ideas started making sense.
Thinking should be hard, that's what makes it valuable. Writing all your thoughts makes it easier, and TK is the perfect place to do so. My random musings have ultimately turned into:A book draftA marketing memo I was proud to share with the companyBlog posts that reached thousands of readersWho knows what else is yet to come? The more I write, the more possibility those nuggets of thoughts turn into polished, influential writing that spreads.It's not just having a place to drop the thoughts -- TK's AI helped find the connections between what I originally thought were random, unrelated ideas. But when you have a place to write down all your thoughts and an agent combing through your scribbles for the gems, it's much easier to start turning notions into notes into the next big thing.
All this to say, I have loved working on and in TK and I can't wait to bring it to more users!

我多年来一直用 Ulysses，这是第一个让我考虑放弃它的写作应用。这说明问题。我是忠诚型用户，所以跳船改用 TK 对我来说是件大事。如果你经常有转瞬即逝的想法，有时想把它们变成文章、书、分享给一群人，或者只是通过养成习惯来锻炼写作肌肉，TK 比现在任何写作应用都好用。而且我能在应用里一边继续写，一边让 AI 助手帮我做研究……这真的很特别。
