Loach v1.1.0 is out with private chats, attachment previews and regenerate response buttons

[ztcs-software]

Our app received a quality-of-life upgrade, especially around privacy and how you handle the stuff you send into a chat.

👉 Download Loach v1.1.0
or update directly from the app in Settings → Updates.

Private Chats

There's a new ghost icon in the title bar. Click it and you're in Private Chat - a dark, ephemeral space where nothing is saved to disk and nothing leaves your device. Everything is wiped the moment you close the chat, MCP and web fetch tools are blocked, and only local Ollama models are available in this mode. It's for the conversations you don't want hanging around in your sidebar.

Regenerate responses

Don't love the answer you just got? The last response from the LLM now has a Regenerate button. It drops the reply, re-sends your turn, and streams a fresh one in place.

Attachment previews

Loach can now preview images, render PDF files, open text and code in Canvas or show a file-info card for everything else - with Save button wherever it makes sense.

Test connections

Settings → Providers now has one-click probes for Ollama and any OpenAI-compatible endpoint. It tells you the daemon version, model count, or a readable error so you can verify a base URL + key without having to open a chat and watch it fail. There's also a presets dropdown that fills in the right endpoint for OpenAI, llama.cpp, LM Studio, vLLM, and LiteLLM.

More Tones

We added Direct (replacing Concise), Playful, Skeptical, and Socratic. The Settings page got a "What each tone does" drawer so you can browse them without guessing.

Other minor changes

• Low VRAM is now a per-chat toggle in the Simple parameters view, including in Private Chat.
• A Features tab in Settings collects Thinking, Temporal awareness, and Low VRAM in one place.
• Space chat rows got the same right-click menu as the main sidebar.
• An archive Remove all for nuking every archived chat in one go.
• If a message fails to send, your composer draft is restored instead of vanishing.
• Code Canvas line numbers line up again, PDF previews no longer clip, and the tray icon shows up on first launch.

Notes on previous minor releases

In previous Loach v1.0.1 and v1.0.2 releases we focused on improving MCP, performance (faster launch and first response) and security. Some minor bugs were fixed and copy / paste messages reworked for better usability.
