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, then copying the numbers back: that friction adds up.
The toolkit is the answer to that. Each tool does one job: paste text, get numbers, move on. 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 gap is what Authorlytica fills. Log a session in 10 seconds and the streak, daily chart, and pace projection update on their own. No payment required, three active projects on the free plan. The toolkit and the tracker work well alongside each other but neither needs the other.
