The Future of AI Chat is Here

Whether you're a developer, creative professional, researcher, or just someone who loves having intelligent conversations, v5.1.0 brings powerful new capabilities that make your AI assistant more helpful, faster, and smarter than ever before.

This isn't just an update; it's a complete evolution. From connecting directly to your GitHub repositories to remembering your unique preferences, LeemerChat is now personalized to you and your code.

Everything Shipping in v5.1.0 (Parts 1–7)

  • Tool system re-architecture and utility tool expansions.
  • Image generation access fixes plus Mistral model support.
  • Major chat latency reductions and faster response times.
  • Concurrent chat generation with background job support.
  • AI Memory with opt-in preference learning across chats.
  • Second Thought expert consultations across top frontier models.
  • GitHub Connect and codebase chat mode for instant repo context.

Codebase Chat: Talk to Your Code

Imagine asking your AI assistant: "How does authentication work in my codebase?" or "Where is the payment processing logic?" and getting instant, accurate answers with full context of your entire repository.

Codebase Chat Mode connects your GitHub repositories directly to LeemerChat. It's like having a senior developer who's memorized your entire codebase, ready to answer questions 24/7.

Beta note: Codebase Chat is in beta while we refine retrieval quality, scale limits, and latency. We're actively experimenting with new indexing approaches, a fresh architecture, and additional models to make this experience even more reliable.

Why not GitHub Copilot?

LeemerChat gives you a wider model lineup than Copilot plus higher usage limits for the price. That means you can choose the right model for the job (fast, deep reasoning, or long-context) without running into caps as quickly. If you want repo-aware chat with flexible model choice, this is it.

We're also rolling out PowerCode agent connectivity soon. It uses the same GitHub access you already grant, so advanced coding agents can operate on your connected repositories without a second setup.

AI Memory: It Finally Listens

Tired of repeating "be more concise" or "I prefer technical explanations"? With AI Memory, your assistant learns your preferences and applies them automatically to every conversation.

Please keep your answers concise and technical from now on.
Preference learned: "Concise & Technical"
Understood. I've updated your global preferences. Future responses will be direct and focus on technical details.

Natural Learning

Just say "I prefer shorter answers" in conversation, and it's saved automatically (opt-in).

Topic Specific

Set different preferences for math, coding, or creative writing tasks.

Cross-Device Sync

Your preferences follow you everywhere, across all your devices.

Full Control

View, edit, or clear your memory at any time in Settings.

Lightning-Fast Responses

We've dramatically improved response speed. Your AI assistant now responds up to 3x faster in many cases, with sub-3-second response times becoming the norm for fast models.
