AntiChat 0.0.3

AntiChat is a free, private AI app for Mac (Apple silicon, macOS 26 or later). Chat, voice, pictures and short videos run on your own Mac with open models. Nothing you type or say is sent to a server, and it works offline once the models are downloaded.

Download: AntiChat-0.0.3.dmg below, or from https://antichat-site.vercel.app/download/. Open the disk image and drag AntiChat to Applications. AntiChat 0.0.1 and 0.0.2 update themselves to 0.0.3 through their signed update feed. The app and the disk image are signed with Developer ID and notarized by Apple. The SHA256SUMS file lists the checksum of the disk image.

What's new in 0.0.3

• New pack icons. New 3D pack icons for Chat, Voice, Photo, Video and Evil Mode in setup and Settings.
• Test fixes.

Known issues

• Speed: a sent message appears about 34 ms after you press Enter (the target is 16 ms). A reply can stutter briefly while it streams in, more often on the slowest supported Macs.
• Video: clips get slower with each video in a row (about 106 s, against a 90 s target). The first preview can take 38–76 s to appear. Image-to-video isn't offered on 24 GB and 48 GB Macs yet; a fix is planned for the next video runtime.
• Busy graphics: when another app uses the graphics chip heavily, AntiChat pauses after about 12 s and may name the wrong app.
• Search and citations: on the smallest and largest chat models, citation checks are still just under their accuracy target. Search on small Macs can be slow.
• Charts: a few spreadsheet-chart requests don't produce a chart yet.
• Looks: some screens don't fully match the intended visual polish yet.
• Legal pages are drafts pending legal review.

AntiChat 0.0.2

AntiChat is a free, private AI app for Mac (Apple silicon, macOS 26 or later). Chat, voice, pictures and short videos run on your own Mac with open models. Nothing you type or say is sent to a server, and it works offline once the models are downloaded.

Download: AntiChat-0.0.2.dmg below, or from https://antichat-site.vercel.app/download/. Open the disk image and drag AntiChat to Applications. AntiChat 0.0.1 updates itself to 0.0.2 through its signed update feed. The app and the disk image are signed with Developer ID and notarized by Apple.

What's new in 0.0.2

• Connections are here. Link Gmail, Calendar, Drive, Slack, Notion, GitHub, Linear and Outlook in Settings › Tools & Connections, through Composio and AntiChat's relay. You sign in to each service in your browser; AntiChat never sees your password. Only connector requests go through the relay, and only when you use a connection. Disconnect one or all at any time.

AntiChat 0.0.1

AntiChat is a free, private AI app for Mac (Apple silicon, macOS 26 or later). Chat, voice, pictures and short videos run on your own Mac with open models. Nothing you type or say is sent to a server, and it works offline once the models are downloaded.

Download: AntiChat-0.0.1.dmg below, or from https://antichat-site.vercel.app/download/. Open the disk image and drag AntiChat to Applications. The app and the disk image are signed with Developer ID and notarized by Apple. The SHA256SUMS file lists the checksum of the disk image.

What's in 0.0.1

• Four packs, one chat window. Chat, Voice (spoken conversations you can interrupt), Photo (make and edit pictures) and Video (short clips, and animating your pictures). You install only the packs you want, and the app picks model sizes that fit your Mac.
• Normal and Evil modes. Evil mode is an opt-in, 18+ mode with its own models and terms. The child-safety check stays on in every mode.
• Web search with checked citations, file output (spreadsheets, documents, decks), a code sandbox, and remote MCP connections you add yourself.
• Private by design. No account and no telemetry. A network ledger shows every connection the app makes.
• Updates itself in the background through a signed update feed.

• Busy graphics: when another app uses the graphics chip heavily, AntiChat pauses after about 12 s and may name the wrong app.
• Cloud connectors (Composio) are not available yet. Their relay service isn't deployed, so they are hidden in this release. MCP servers you add yourself work.
• Search and citations: on the smallest and largest chat models, citation checks are still just under their accuracy target. Search on small Macs can be slow.
• Charts: a few spreadsheet-chart requests don't produce a chart yet.
• Looks: some screens don't fully match the intended visual polish yet.
