Pulse Local runs a tuned open model on the Mac for budgeting
Pulse Local is a Mac budgeting app that runs its tuned open models on the user's machine, with ledger and chat answers never leaving the laptop. The build downloads 2.9 GB of models on first launch, including a 2.5 GB verifier that reads every money answer and can be switched off, and is free with an optional donation.

Why it mattersA team shipping a product that handles sensitive numbers can now test whether a tuned small open model running on the user's laptop answers the common questions well enough to drop the cloud call that most privacy policies pretend is safe.
A budgeting app that keeps the ledger on the user's machine is now common. One that also keeps the AI chat on the machine, so the question itself never leaves the laptop, is new. Pulse, a small company that was selling a browser, posted Pulse Local on Hacker News with 55 points. The pitch is one sentence: "Local" usually means your data; this one keeps the question too.
The app is a complete budgeting tool, with spending plans, categories, rules, cash flow, forecast and a chat that answers from the user's own transactions. The chat uses tuned small open models that run on the laptop, with no cloud endpoint for the question. Pulse publishes the tuned weights on Hugging Face.
What downloads and what runs
The first launch pulls 2.9 GB of models in total, which Pulse's own page describes. The largest file, 2.5 GB, is a verifier that reads every money answer the chat produces and can be switched off in Settings. The smaller model, under 500 MB, is a Qwen3-based assistant tuned by the team for money questions. The app sends two kinds of request over the network: those model downloads once, and a version check that asks whether a newer build exists. The version check carries nothing about the user and can be switched off.
What the chat answers
The site shows the questions the chat is built for: how much the user spent on restaurants, what the subscriptions are, whether cash flow was positive last month, what a sinking fund is. The app labels AI answers, shows which month and category it included in each figure, and refuses to answer when its two readings disagree. On the sample ledger, the math was checked against six months of real transactions and matched to the cent, according to the site.
What is paid
Pulse Local is free with an optional donation at twenty, forty or any dollar amount; every button ends at the same download. The one running cost is Plaid bank sync, which carries a Sync Pass of $29 a year and is US-only for now. Everywhere else the app runs in Local mode and imports a CSV in the user's own date and decimal format. The country picker names 75 countries and the ledger is kept in one currency, with no exchange rate conversion.
The limits
The app is a beta on Mac with Apple Silicon, signed and notarised by Apple. Windows is in development. The company says the chat can misunderstand a question, which is why the verifier exists, and leaves the final decision about what to do with a number to the user.
Reveneau's take, for a team building anything that handles money, health or legal data: a tuned small open model running on the user's machine is a real third option alongside the cloud API and the locally stored but cloud-answered chat. The questions the chat is good at are the shape of the questions that fit a small model: look up a figure, compare two months, explain a term. A team ready to try the pattern should start with those shapes and keep the cloud fallback for the long tail.
