Markdown Task List Summarizer
Paste a Markdown checklist and get a done/pending count and completion percentage — or list just the done or pending tasks, or export JSON. Runs entirely in your browser.
What this tool does
Paste a Markdown checklist and instantly see how many tasks are done, how many are pending, and your completion percentage — right in your browser. Nothing is uploaded to a server: it runs locally, works offline, and needs no sign-up. Switch the Output to list only the completed or only the remaining tasks, or to export a JSON object for scripts and dashboards.
What counts as a task
A task is a GitHub-flavored Markdown checklist item — a list marker followed by a checkbox:
| Written as | Meaning |
|---|---|
- [ ] write tests | pending |
- [x] write code | done |
* [X] ship it | done (any marker, upper- or lowercase x) |
1. [ ] follow up | pending (numbered lists work too) |
Unordered markers (-, *, +) and ordered markers (1., 2)) are all
recognized. Nested/indented items are counted. Plain list items without a
checkbox, headings, and prose are ignored — so you can paste a whole document and
only the real tasks are summarized.
Output modes
| Output | What you get |
|---|---|
| summary (default) | One line: total, done, pending, and percent complete. |
| done | Just the completed task texts, one per line. |
| pending | Just the not-yet-done task texts, one per line. |
| json | {"total":…,"done":…,"pending":…,"percent":…,"done_items":[…],"pending_items":[…]} for scripts. |

FAQ
Is it free and private?
Yes — your checklist never leaves your device, and the tool keeps working offline once the page has loaded.
Does it support numbered lists?
Yes. 1. [ ] task and 2) [x] task are both
recognized alongside the -, *, and + bullet markers.
Why isn't one of my lines counted?
A task needs a checkbox right after the
list marker — - [ ] text or - [x] text. A bullet without a [ ]/[x]
checkbox is treated as a plain list item and ignored.
How is the percentage calculated?
It's done ÷ total, rounded to the nearest
whole percent. An empty list reports 0%.
