ChatGPT Desktop is still the default chat app on a Mac. In July 2026 OpenAI shipped ChatGPT Work and retired the older agent mode. Work can click, type, and move files. That is real agency. It is still pointer-driven, OpenAI-only, and online.

This page is the free, no-subscription shortlist for macOS. Paid and free together, by job: Mac apps like ChatGPT. Product head-to-head: Dottie vs ChatGPT Desktop.

Requirements for Dottie, when it appears: Apple Silicon, macOS 15.4+.

TL;DR

Job on your Mac	Free app to open
Native files / apps / calendar / Mail / Terminal	Dottie
Long documents, Artifacts, careful reasoning	Claude Desktop (free tier)
Zero install writing tools	Apple Intelligence
Local / offline open models	Ollama or LM Studio
Cited research	Perplexity (free)

What “free” means on this page

Free means you can start without a monthly plan. API keys you already pay for, hardware time on local models, and optional paid upgrades later do not disqualify a pick. Tools that lock AI behind a subscription (Raycast Pro from $8/mo, BoltAI) stay on the paid map.

ChatGPT itself has a Free plan with limited Work on desktop. This list is for people who already decided ChatGPT is the wrong shape: no local models, no wake word, no native Finder / Mail / EventKit tools.

The split: chat vs computer use vs Mac agent

Chat apps answer and write. Computer-use agents (ChatGPT Work, Claude Cowork) drive the pointer. Native agents call macOS APIs.

Work with Apps reads a supported allowlist. Computer use clicks the GUI. A native agent calls Finder, EventKit, Mail, Terminal, and screen OCR as tools. That is the same split as Dottie vs ChatGPT.

1. Dottie: Best free ChatGPT alternative for Mac

Dottie is a free native Mac AI agent. Voice or text in, system action out through 134 tools. “Find every PDF in Downloads larger than 10MB and move them to Archives” moves the files. ChatGPT Work may click through Finder. Dottie calls the APIs.

Voice is a wake word (“Hey Dottie”), barge-in, and spoken replies. ChatGPT Voice lives inside the chat window and needs a connection.

Models are three paths:

Path	When to use it	Cost
Local (MLX / Ollama)	Nothing leaves the Mac; offline work	Hardware time only
BYOK (xAI, OpenAI, Anthropic, Cerebras)	You already pay for frontier APIs	Your existing API bill
Dottie Pro ($20/mo)	Managed models without key plumbing	Optional. Does not unlock the 134 tools

The app is free. Cumulative downloads are past 1,000 (api.dottie.ai, 2026-08-18). Apple Silicon and macOS 15.4+ only. First 10 minutes: Getting Started with Dottie on Mac.

What ChatGPT cannot do that Dottie can:

Task	ChatGPT Desktop	Dottie
Organize Downloads by type	Chat: a script. Work: may click Finder	Moves the files via tools
”What’s on my screen?”	Screenshot or Work with Apps allowlist	OCR reads the display
Create a 3pm calendar event	Plugin or computer use	EventKit
Summarize a PDF on disk	Upload required	Reads it from the filesystem
”Hey Dottie, what time is it?”	No wake word	Hands-free

Best for: Mac control, wake-word voice, local or BYOK models.

2. Claude Desktop: Best free long-document chat

Anthropic’s Claude app is the strongest free chat alternative. Current models (Opus 5, Sonnet 5) advertise a 1M token context window. Artifacts, file uploads, and voice mode ship on the free tier, with usage limits.

Free tier includes: Sonnet-class access with caps, file and image uploads, Artifacts, voice mode (no wake word, cloud only).

Where it still loses on a Mac: no local open models, no offline path, no native macOS APIs. Cowork computer use is a research preview on paid plans. Head-to-head: ChatGPT vs Claude on Mac. Product vs a native agent: Dottie vs Claude on Mac. Wider field: Claude alternatives for Mac.

Best for: Long documents and careful reasoning without paying yet.

Price: Free / Pro $20/mo

3. Apple Intelligence: Best zero-setup option

Already on your Mac if you are on a current macOS. No download, no account, no key.

Free features: Writing Tools (rewrite, proofread, summarize) in any text field, notification summaries, basic image generation, Siri.

Limitations vs ChatGPT: Siri is still rigid. Personal context, on-screen awareness, and app actions remain delayed. No third-party models. No local open weights. Head-to-head with a Mac agent: Apple Intelligence vs Dottie. Broader field: Apple Intelligence alternatives.

Best for: Quick writing help without leaving the current app.

4. Ollama + Open WebUI: Best self-hosted chat

Run open models (Llama, Mistral, DeepSeek) locally with a ChatGPT-like browser UI.

brew install ollama
ollama run llama3.1

Add Open WebUI for the familiar chat layout.

Free because: weights run on your hardware. No API bill. No account.

Limitations vs ChatGPT: smaller models, no plugins, no image gen, some setup, RAM (16 GB+ is comfortable). Not a Mac agent. Pairing Ollama with Dottie gives you the same local weights plus system tools. Tool comparison: Ollama vs LM Studio. Apple Silicon setup: run local AI models on Mac.

Best for: Privacy-first users who want a ChatGPT-shaped window and can tolerate a CLI.

5. LM Studio: Best local GUI, no terminal

LM Studio is the point-and-click local runner: browse models, download, chat. No brew required. Free for personal use.

Where it beats Ollama: friendlier first hour, built-in model catalog, Apple Silicon builds.

Where it loses: still chat-only. No wake word, no Finder tools, no EventKit. Same local-vs-cloud decision as the Ollama path. Head-to-head: Ollama vs LM Studio.

Best for: People who want local models and refuse a terminal.

6. Perplexity: Best free cited research

Perplexity answers with sources. That is the job ChatGPT’s browsing still fumbles when you need to check a claim.

Free tier: cited answers, follow-ups, a daily Pro Search cap.

Limitations vs ChatGPT: no Mac automation, no wake word, no local models, no computer use. Pro is $20/month if you live in deep research.

Best for: “I need an answer I can verify,” not “move these files.”

Feature comparison

Switching from ChatGPT to Dottie

Chat still works the same: type a question, get an answer. The difference shows up when you ask it to do something.

In ChatGPT: “Rename every screenshot on my Desktop to include today’s date.” ChatGPT writes a bash script. Work may click through Finder.

In Dottie: the same prompt runs the tools, renames the files, and reports what changed.

ChatGPT is a conversation partner plus a computer-use agent. Dottie is a coworker with native Mac access. Architecture: What Is Dottie Desktop?. Timed first run: Getting Started.

How to choose

You want ChatGPT’s breadth (images, live web, Work): stay on ChatGPT Desktop. Pricing starts free; Plus is $20/mo.

You want the Mac itself to change: Dottie. Local, BYOK, or Pro.

You want long documents and Artifacts: Claude Desktop free tier.

You want zero install: Apple Intelligence, then leave when Siri stalls. Voice-only split: Siri alternative for Mac.

You want weights on the machine: Ollama or LM Studio. Add Dottie if those weights should also move files.

You want citations: Perplexity.

The honest take: ChatGPT is still the best chat product. “Chat” is one job on a Mac. If you searched for a free alternative because chat never moved a file, start with Dottie. Category ranking: best AI assistants for Mac.

What's the best free ChatGPT app for MacBook in 2026?

If you want a ChatGPT-shaped chat window, Claude Desktop's free tier or local Ollama / LM Studio.

What happened to ChatGPT Agent Mode?
