Instantly compare outputs from GPT-5.2, Claude, Gemini, and other top models side-by-side with a single API call, identifying the best performer for your specific task. Create superior responses by blending the best components from multiple AI model outputs, combining their unique strengths into one optimized result. Automatically route each request to the most suitable AI model using smart routing, ensuring optimal performance without manual selection. Maintain production reliability with circuit-breaker failover that detects and skips unhealthy models, preventing system-wide failures. Protect sensitive data with zero-retention mode where prompts and responses are never stored or used for training. Pay only for what you use with a flexible pay-per-use credit system and no subscriptions, with initial free credits that never expire. Integrate in minutes with a low-friction migration process estimated at 15 minutes, swapping your existing client to the LLMWise SDK. Receive real-time, streamed responses with detailed per-model metrics on latency, token counts, and cost for full transparency.
Receive consensus-driven answers with higher accuracy by combining and aligning responses from multiple AI models, not just one. Get evidence-backed intelligence for critical decisions using the Verify mode, which extracts factual data and cross-references conclusions with web search. Balance speed, accuracy, and cost for any task by selecting from three processing modes: Unify for fast synthesis, Justify for deliberated accuracy, and Verify for verified facts. See exactly how conclusions are reached with full transparency into the AI's thinking process, from initial responses through conflict analysis to final consensus. Reduce AI hallucinations and errors through a built-in deliberation step where models review and refine conflicting answers before presenting a unified response.
Uncover hidden AI bias and preconceived notions by seeing where frontier models like ChatGPT, Claude, Grok, and Gemini agree and disagree on the same query. Make confident, data-driven decisions with mathematical rankings and comparisons generated from multiple AI perspectives, not just one. Plot data and generate estimates with greater reliability by leveraging the consensus or divergence between four powerful AI models. Enhance operational efficiency and task management with a robust, customizable interface that adapts to your specific business needs without requiring specialized knowledge. Predict market trends and manage business risk using AI-driven insights and analysis tools designed for both B2B and B2C service optimization.
Get the strongest answer from every AI model by running ChatGPT, Claude, Gemini, and Grok side-by-side, then synthesizing the best ideas into one definitive response with Compare Mode and Synthesis. Build a smarter project knowledge base automatically as LettiB accumulates goals, decisions, preferences, and facts into Project Memory, making every new prompt more context-aware without manual effort. Maintain complete data ownership and privacy with encrypted API keys and a strict no-training policy, ensuring your sensitive work never leaves your control. Pay only for the AI services you use directly through the Bring Your Own Keys (BYOK) model, eliminating usage markups and giving you full transparency. Organize all comparisons, syntheses, and chats into project folders so great responses compound into a searchable knowledge base instead of disappearing in endless threads. Start comparing up to 2 AI models at once with 5 projects and 10 monthly syntheses for free, scaling to unlimited usage with paid plans starting at $15/month.
Compress hours of research into seconds by firing multiple prompts at once across top AI models for instant diverse perspectives Eliminate single-model bias with multi-model cross-checking that lets you compare answers from GPT-5.5, Claude 4.6, Gemini 3.1 Pro, and more side by side Build the ultimate answer by cherry-picking the best lines from different model responses into one refined output Grasp complex concepts instantly as AI outputs transform into interactive mindmaps that reveal connections and hierarchies Produce defensible arguments and high-quality proposals for winning deals or securing job offers using multi-model synthesis and critique Save every critical insight permanently by highlighting key parts of AI answers and adding your own notes alongside them Refine AI responses on demand with the critique feature that forces the model to address weaknesses and gaps for precision answers Explore multiple research angles simultaneously without context switching through parallel synthesis across all hosted models Keep proprietary research secure with a guarantee that your prompts, uploads, and chats are never used to train any model
