🚀 LettuceAI 1.0-beta_4 - Memory System, Library UI, Navigation Overhaul & More

Hi everyone! 👋

This is the biggest and most important update LettuceAI has had so far.
Beta 4 has a brand-new navigation layout, a fully redesigned Library page, an in-house embedding model, and the long-awaited Manual + Dynamic Memory systems, all powered by a new SQLite database backend.

🌟 Highlights

Modernized Navigation

• Completely redesigned top navigation bar following modern UI standards
• Settings moved from bottom navigation to the top
• Bottom navigation now hosts the brand-new Library section

New Library Page

• Characters and Personas are now displayed in beautiful card layouts
• Avatar-based dynamic background colors
• Cleaner, more visual experience
• Character/Persona management moved out of Settings

Manual & Dynamic Memory Arrive

Introducing a full memory system designed for long-term, consistent roleplay:

📌 Manual Memory

• Users can pin important facts or details
• Not restricted by token window
• ⚠️ May increase token usage on paid models if used excessively

🔄 Dynamic Memory (Efficient + Long-Term)

Dynamic Memory uses a sliding window of the last N messages.
Every N messages, the app:

1. Summarizes them in the background
2. Stores the summary as a long-term memory
3. Uses our in-house embedding model (lettuce-emb-512d-v1) to retrieve only the most relevant memories for each response. The model is trained on a large dataset of roleplay conversations and is fully optimized for medium-end mobile devices, using less energy and achieving response times under 400ms.

This system has a huge benefit:

Dynamic Memory stops whole chat histories from being sent to the model, which uses up tokens much less quickly and makes long-term roleplay cheaper, especially with paid models.

Users can also choose which model powers:

• The memory summarizer
• The memory manager (embedding search)

Together, this provides a persistent experience without burning tokens.

🌐 New Provider Endpoint Support

Beta 4 brings a huge wave of new AI provider integrations.
LettuceAI now supports the following additional endpoints:

• Deepseek
• Featherless AI
• Google Gemini
• MoonShot AI
• NanoGPT
• Qwen

Storage System Rebuilt (Breaking Change)

All storage has been migrated from mixed .json / .bin formats to a robust SQLite (.db) backend.

Character & Persona Import/Export

• Added import/export support via .json files
• Easy backup, sharing, and syncing between devices

UI & UX Improvements

• Massive consistency pass across the entire app
• Optimized ChatHistory and Character/Persona edit pages
• Pinned messages are now fully functional
• Required-variable checks added to the Prompt Editor
• Bottom popup animations redesigned to eliminate stutter

Improved Usage Tracking

Usage events are now typed, including:

• Chat
• Regenerate
• Continue
• Summaries (tool calls)
• Memory manager actions (tool calls)

General Improvements

• Smoother transitions and cleaner component layouts
• Many polish fixes across spacing, alignment, and typography

Migration Notes

• This update performs major database migrations
• Old .json/.bin formats are no longer supported (App will auto migrate)

❤️ Thank You

Beta 4 lays the foundation for the next generation of LettuceAI. A more intelligent, persistent, and efficient role-play experience with memory that actually works.
