The universality of "software" as a digital "techne" makes the aim of this article too fuzzy. Using the exact author's descriptions, here are some more "defined" apps that are working toward his goal of "dynamic documents as personal software."

- "Write formulas that compute" + "Interactive widgets" anywhere on the page :

    - For the simplest sheet-like computations -> https://reactivepad.com/
    - For a wider gamut of DB/Sheet type formulas -> https://coda.io/ (on top of its no-code relational DBs)

- "Users can create live searches that extract information from freeform text" into "Structured data views" :

    -> https://tana.inc/ magically turns every typed line of text into a row of a Semantic Graph DB. Then, no-code queries are editable in multiviews (like notion-style DB views for every block of text anywhere).

These apps do not need extensive configuration or plugin integration to achieve these goals. They are not even "low-code". On the contrary, "Potluck" aims to be more "programmable" : more like a "programming portal as a doc. (https://maggieappleton.com/programming-portals)

Edit : He already mentioned that "Coda’s goal is particularly close to ours." Maybe a "Coda+Tana.inc" hybrid will get us nearer to his aim of "computations run on data interpreted from freeform text" as he expressed it.
