LettiB

LettiB is a unified workspace designed specifically for power AI users who need to centralize their workflow within a single professional environment. This tool allows users to manage and compare the most powerful language models on the market, such as ChatGPT, Claude, Gemini, and Grok, eliminating the data fragmentation that occurs when working across multiple browser or mobile tabs.

The platform operates on a BYOK (Bring Your Own Keys) model. Users integrate their own API keys from providers like OpenAI, Anthropic, Google, xAI, or Groq. This technical approach ensures that data remains under the user's control and that payments for computing consumption are made directly to the original providers, without additional surcharges for model usage.

Among LettiB’s core capabilities, the following functional features stand out:

Compare Mode: Allows sending a single prompt simultaneously to up to 6 AI models in parallel. Users can view responses via real-time streaming, facilitating the critical evaluation of results, tone, and accuracy from every provider on a single screen.

LettiB Synthesis: This feature acts as a smart editor that allows users to merge the best ideas from different models into a single, authoritative final response. The result is a polished text that combines the strengths of each AI with source attribution.

Project Memory: The system automatically accumulates objectives, decisions, and preferences within each project. This contextual memory ensures that every new query is smarter, as the tool remembers relevant facts and preferences from the previous workflow.

Structured Organization: Chats, comparisons, and syntheses are organized into project folders. This enables the creation of a knowledge library that grows with use and is fully discoverable via a global search engine.

Data privacy is a critical aspect of LettiB's design. API keys are stored with encryption, and the platform ensures that conversations are not used to train third-party models. The user maintains full ownership of their outputs, with the option to export or delete information at any time.

This tool is a robust solution for those looking to optimize their AI productivity, providing technical and organized management of multiple models through a clean interface. By centralizing interaction with various LLMs, LettiB serves as an efficient command center for developing complex projects and generating high-quality content.
