I keep everything in Notes, will definitely use.
Just quickly tried it. Is the app notepad friendly? I read that handwriting produces different/(better/more) connections in the brain than typing.
@alquinsmiles we don't have a feature yet that allows directly handwriting notes into TK, that's something the team is considering. I hack this by writing my notes and then adding them to TK and asking the assistant to pull out the text. I
Without medium & TK I would not have started writing and maybe finishing my 1st book soon.
Wow @dune_dain ! Good luck with your book! Let us know how it goes. Glad TK is helping your writing process.
do Kindle highlights come in too?
Hi @thomas_wazza , we don't integrate with Kindle but there is a highlight feature in TK.
I'm very anti-AI for writing. I'm reluctantly adopting it for programming in carefully tested doses, because it's good for generating stuff where I don't care too much about the design.
TK added some nice community feel and a different kind of sharing from Medium, which I really appreciated whilst utterly ignoring its AI features.
I like the framing here — notes that compound instead of just piling up. The part I'd actually use is the MCP side: being able to pull my notes into the tools I'm already working in, instead of the notebook becoming another silo. The export story matters to me too — full export, plus copying single notes as markdown, means I'm not locked in if my workflow changes. The tension I keep coming back to is keeping the writing unmistakably mine while the agent connects dots in the background — curious how you draw that line in practice.
@jcbuilds From a product perspective, we've made a few design choices to help separate your writing from the assistant's (or from the agent you connect to with MCP):
we allow you to highlight text that's been created by the assistant/agent in your notes, and optionally also show this attribution to readers. This can help you keep track of what is explicitly your voice, and what the agent's contributed. Some people use this highlighting as a reminder to go back and edit passages to make them more their own, some people use it for transparency for their readers, some people are happy enough with the assistant's output to incorporate it as part of their voice, and that's their call.
if the assistant wants to make changes to your notes, we always allow you to explicitly accept or reject them, and we'll often provide multiple options for you to choose from. These changes are, again, attributed to the assistant.
many of our skills push the assistant to provide written feedback, rather than directly editing the document.
Personally, I use the assistant and various tools connected via MCP to synthesize/summarize data from a lot of different sources into new notes in TK (these also have AI attribution). I read those notes and do share them with other people, with explicit caveats that they're LLM-generated, and then use them to inform my own writing in other, LLM-free notes. For instance, I have a couple of Claude Code jobs that collate user feedback from all the notes I can read in TK, then add summaries and links to a "Product Feedback" library. I read those summaries every day, and try to reply to feedback that needs it. But I also try to write about TK-as-a-product for my co-workers, and I'll use that feedback to inform my writing (and maybe the @TK inline completion to find notes I'm thinking of) without using the assistant's words directly.
this looks awesome. congrats on the release, medium!
