DonePile: I Let an Open-Weight Model Do the Task I Dread Most — Sorting My Messy Notes

Raymonds Mason — Thu, 22 Oct 2026 09:29:58 +0000

This is a submission for the Hacktoberfest "Slow and Steady" Challenge — Week 3: Open Source AI, on DEV.

What I Built

DonePile — Notes to Done List.

Everyone has the pile. Mine looks like this: half-finished meeting notes,
a brain-dump typed at midnight, "sarah said she can fix it by friday??",
"renew the domain before it expires on the 28th!!", "CALL THE DENTIST".
The dreaded task isn't doing the tasks — it's the 20+ minutes of re-reading,
rewriting, assigning and prioritising it takes to turn that pile into a list
you can actually act on. So I automated exactly that dreaded step.

DonePile takes a messy pile of notes and returns a clean, prioritised
done-list: every actionable item extracted, with an owner, a due
day/date as written in the notes, and a priority (High / Medium / Low),
grouped and checkbox-ready in Markdown or in a tiny local web UI.

And it does it entirely on my own machine, on CPU, with an open-weight
model. No cloud, no API key, no account, no per-token meter — because
meeting notes and brain dumps are precisely the text I don't want to paste
into someone else's cloud.

Demo

📦 Code: https://github.com/billythompsons/donepile
▶️ Live demo / demo output: https://github.com/billythompsons/donepile/blob/main/evidence/SMOKE-TEST.md

Fastest demo (one command, on the bundled messy sample):

python demo.py

Real input (excerpt, from samples/messy-notes.txt):

ok so website landing page hero text is still wrong, sarah said she can fix it by friday??
mike: api keys are expiring, he needs to rotate them before monday or the demo breaks
renew the domain before it expires on the 28th!! costs like $12 just do it

Real output: the smoke test in the repo (evidence/SMOKE-TEST.md) saves the
exact raw model output and the rendered done-list from an actual run —
13 tasks extracted locally (about 40 seconds on a small 2-core VM; a typical
laptop is faster), including:

Rotate API keys — Owner: Mike · Due: monday · High
Send invoice to client — Owner: Priya · Due: wednesday · High
Renew domain — Owner: Me · Due: 28th · High
Team lunch order — Owner: Alex · Due: thursday morning · Low

There's also a local web UI if you prefer paste-and-click:

python app.py   # then open http://127.0.0.1:8765

Full recorded demo output: see demo-output.md and evidence/SMOKE-TEST.md in the repo — both are files, captured from a real run, not mock-ups.

Code

git clone https://github.com/billythompsons/donepile
cd donepile
python3 -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt   # builds llama-cpp-python (needs a C compiler + cmake)
python demo.py                    # first run downloads the model once (~1.07 GB)
python -m donepile.cli your-notes.txt -o done.md

Project layout:

donepile/engine.py   # local inference: model download, llama.cpp load, extraction prompt, JSON parsing
donepile/render.py   # deterministic formatting only: dedupe, priority sort, Markdown/text, effort-saved estimate
donepile/cli.py      # command-line interface
app.py               # local web UI (Python standard library only)
demo.py              # one-command demo on the bundled sample
samples/messy-notes.txt
tests/               # helper tests (no model needed)
evidence/SMOKE-TEST.md  # real input -> raw model output -> rendered list

How I Built It

Open-weight model at the core: Qwen2.5-1.5B-Instruct (Apache-2.0), in
GGUF Q4_K_M format (~1.07 GB). Small enough to run happily on an ordinary
laptop CPU, capable enough to read a messy pile and understand "he needs to
rotate them before monday" means Mike owns the API keys, due Monday.

Open-source AI harness: llama.cpp, via llama-cpp-python (MIT). It loads
the GGUF weights, runs chat-completion inference on CPU threads, and after
the one-time model download the whole thing works fully offline.

The technique is mostly a strict prompt + honest plumbing:

A system prompt that demands only a JSON array of {task, owner, due, priority} objects — every actionable item, nothing invented, no prose — plus one small worked example.
Chunking: the pile is fed to the model 4 lines at a time. I first tried one big call (and a 0.5B model); owners and dates drifted to the wrong lines. Small models keep them attached far more reliably on short inputs — that one change took the output from mush to a list I'd actually use.
Low temperature (0.1), because this is extraction, not poetry.
A tolerant parser that validates each item and normalises priorities.

An honesty note I want in the open: the extraction — the actual reading
and understanding — is the model's work. The only deterministic code after it
drops exact duplicates, sorts High → Medium → Low, and formats the output.
There is no rule-based fallback dressed up as AI; if the model isn't there,
DonePile says so and tells you how to download it.

Limitations, plainly: a 1.5B model is still a small brain. In my smoke
test it extracted 13 solid tasks but skipped the groceries line and folded
"the Q4 slides" into "Get chart from Ben", and it can pick a priority I'd
set differently. I treat
the output as an excellent first draft that takes me from dread to list
in about a minute of CPU time — then I skim and adjust. Dates are extracted as written
("friday", "the 28th"); it doesn't set calendar reminders. Yet.

Why Does Open Innovation Matter?

DonePile exists only because two open things met: a capable
instruction-tuned model published under Apache-2.0, and a community
harness (llama.cpp, MIT) that makes open weights run anywhere — including
a modest CPU with no GPU and no cloud bill.

That changes who gets to build what. "AI that quietly does the boring parts
of life" shouldn't require an API key, a subscription, or handing a company
your private notes. Open weights mean the tool can be inspected, run
offline, forked, and improved by anyone — and a weekend Hacktoberfest
project by one person can stand on the same model a large company uses.
That's the whole spirit of open source, now applied to AI itself: the
capability is shared, so the laziness can be too.

Lazy Payoff

My estimate is deliberately transparent (it's a formula in
donepile/render.py, not marketing): manually sorting a pile costs roughly
1.5 minutes per item + 5 minutes of initial sorting. A typical 14-item
pile is ~24.5 minutes saved — every single time the pile forms, plus the
bigger, unmeasurable payoff: the pile stops being a thing I dread and
avoid, so the tasks on it actually get done.

Less time re-reading my own mess. More time doing — or, in the spirit of
Slow and Steady, not doing. 🦥
