Built for work that can't touch the cloud

Private AI for lawyers, doctors, therapists, and accountants.

LocalChat is an on-device LLM that runs on your Mac. It reads the whole file. Nothing leaves your laptop.

Why local matters

Cloud AI breaks rules you've already agreed to follow

You work under rules. Privilege. HIPAA. Your licensing board. ChatGPT respects none of them — so your real work never gets near it.

Privileged work shouldn't sit on someone else's server

Paste a case file into ChatGPT and it lives on a server you don't own. Their staff can read it. Their next model can train on it. Their lawyers can hand it over.

Patient details don't belong in a chat tool

ChatGPT, Claude, and Gemini weren't built to hold patient information. One pasted note can put you on the wrong side of HIPAA.

Client financials don't belong in cloud AI

Tax returns, payroll exports, P&Ls, and engagement letters carry bank details, SSNs, and private business numbers. Accountants need answers without creating another copy online.

Therapy notes don't belong in training data

Even with the opt-out checked, your intake forms and session notes still go to their servers. Whatever you upload, assume someone else has a copy.

LocalChat is the local LLM that keeps your work on your Mac

The ChatGPT alternative that runs on your laptop. Your files, your questions, and the answers stay on the same machine. No server to leak from. No account to log into. Nothing for anyone to hand over.

Built for

The people who can't put their work in the cloud

  • Lawyers

    Read contracts, depositions, and discovery on your Mac. Ask clause-level questions and get page citations — without uploading a single file.

  • Therapists

    Summarize session notes and intake forms on-device. HIPAA compliance stays simple because the file never leaves your laptop.

  • Accountants

    AI for accountants in busy season: skim tax returns, P&Ls, and engagement letters. Client numbers never touch a cloud account.

  • Consultants

    Brief yourself on client docs, draft proposals, polish decks. Nothing to clear with anyone's IT team.

  • Writers & researchers

    Hand it a whole manuscript or stack of sources. Get outlines, edits, and citations — your unpublished work stays unpublished.

  • Travellers

    Real AI on a plane, in a basement hotel, on patchy hotel Wi-Fi. No login screen between you and the answer.

Model library

A curated catalog, picked for Mac

Reasoning models, vision models, embeddings for memory, even an image generator — every one tested on Apple Silicon and one click to download. Then it works without an internet connection, ever.

Features

A private LLM you can hand the real file to

Built for the work you do — reading long files, comparing answers, drafting. With none of the redacting before you can ask a question.

Drop in the whole file

Hand it a 200-page deposition, a full patient chart, a contract, an intake packet. PDFs, markdown, CSVs, spreadsheets — LocalChat reads the whole thing on your Mac, no copy-paste.

PDFMDCSVXLSXPNGTXT

No account, no logins, no usage tracking

There's no LocalChat account to sign up for. Your prompts, files, and answers stay on your laptop — there's nothing for anyone else to look at.

A project workspace per matter

Each project keeps its own files, conversations, and embedded memory. Toggle 'answer only from this project's files' and the model stays inside the case.

Plug in your Obsidian vault

Point LocalChat at a vault and it scans the notes, follows links, and turns them into searchable memory. Your second brain becomes the assistant's first source.

On-device AI, on a plane or anywhere

Once it's installed, no internet required. Keep working in places where ChatGPT and Claude are blocked or out of reach.

Pick the right LLM for the job

A curated catalog of 25+ on-device models — reasoning, vision, OCR, image gen, embeddings. Swap mid-thread; the conversation stays.
