Why these tools exist
Most writing software is built around the act of drafting. Counting, calculating, analyzing rhythm and limits: these are little jobs the drafting tools handle clumsily, if at all. Switching tabs to a generic web tool, dealing with ads or a signup wall, copying numbers back into your real work is small friction, but it adds up.
The toolkit is the answer to that. Each tool does one job, does it well, and stays out of the way. No upload, no account, no character cap. Bookmark whichever you actually use; ignore the rest.
One thing the toolkit cannot do
The toolkit handles single-session questions: "how many words is this", "how long to read", "how does this passage's emotional arc move." It does not record what you wrote yesterday, last week, or last month. It does not show your streak. It does not project a finish date based on your actual pace.
That is what Authorlytica does: the tracker, not the toolkit. Log a session in 10 seconds and the streak, daily chart, and pace projection update on their own. Free forever plan, three active projects, no card. The toolkit and the tracker work well alongside each other but neither needs the other.
