Born in 2023 to keep work moving when everyone else went dark, LeemerChat now ships background research, podcast studios, writer flows, and a curated model marketplace in one interface. This is the operating system for teams that refuse to juggle tabs.

Unified Intelligence Workspace
Origin & Intent
Repath's weekend insurance policy against model outages became a global canvas once friends felt the difference: no more tab sprawl, no more key wrangling, and a stack that keeps pushing work forward after you log off. Today, LeemerChat blends real-time collaboration with asynchronous agents and research that meets publication standards.
Repath assembled a safety net when ChatGPT outages made work grind to a halt. Early friends used it to keep publishing overnight.
The scrappy backup turned into a unified workshop with writer, research, podcast, and sharing flows tuned for actual teams.
Agentic background runs, email-delivered research briefs, podcast studio refresh, and curated partner models reach production.
Firecrawl-powered web search with context-aware query optimization, enhanced citation display, and persistent source tracking across all models.
Platform overview
Chat, research, writing, podcasting, and voice live together. Each pillar leans on the same personalization, sharing, and session intelligence you see across LeemerChat v4.6.
Realtime chat, voice calling, branching threads, and model mentions keep long-running collaborations tidy while you switch devices without losing context.
Email Agent, researcher pipelines, and podcast studio jobs keep working after you close the tab—results arrive in your inbox with transcripts, citations, and share pages.
Lexical-powered documents with Harvard citations, versioning, tagging, and foldering make long-form work feel like part of the same workspace, not a separate tool.
Account sharing protections, session intelligence, and configurable notifications keep enterprise hygiene without breaking individual flow.
Partner lineup · BYOK clarity · Leemer-branded systems
LeemerChat ships OpenRouter-backed partner models out of the box: DeepSeek Terminus, Grok-4.1-Fast, Qwen3 VL, GPT-OSS-120B, Kimi K2, GLM-4.5, GPT-5 Mini, and LongCat Flash. Exclusive unlocks add GPT-5.1 Chat, Grok 4, and Claude Sonnet 4 for premium contexts.
All OpenRouter models run on the shared backend key so teams avoid per-seat setup; no user OpenRouter keys required.
Bring your own API keys when you need Groq's ultra-low latency or Gemini's grounded multimodality. Without a user key, Groq stays disabled while Gemini falls back to the backend key.
Union architectures like Leemer Heavy blend GLM-4.6 control with Perplexity Sonar research and Qwen-3 long-form polish. The fast variant pairs Gemini 2.5 Flash Lite with Qwen3 Next 80B and Kimi Linear 48B for rapid debate-style synthesis.
Pricing mirrors how builders actually work: prepaid bundles with volume discounts, persistent credits, and clear per-100-message math. Billing pairs with session limits so teams keep predictable spend without losing flexibility.
Research briefs arrive with Harvard-style citations, source heatmaps, and export-friendly layouts. Podcast runs ship transcripts alongside MP3s. Writer documents keep revision history, tags, and summaries so teams can hand off without reformatting.
Modules in practice
The same primitives power different workflows—from outbound research sprints to email triage and podcast launch kits. Here is what ships today.
Fire off multi-hour investigations with parallel web sweeps, numbered citations, and email delivery. Background jobs keep you moving while the agent finishes the literature review.
Forward threads to agent@leemerchat.com to summarize attachments, propose replies, and keep thread context intact across anonymous, free, and paid tiers.
Lexical editor with revisions, tags, summaries, and Harvard citations keeps manuscripts, memos, and briefs tidy while collaborating with multiple models.
Plan, script, and render audio via Lemonfox TTS, then publish transcripts and MP3s to clients without leaving the workspace.
Whether you're testing the partner lineup, deploying Leemer Heavy in production, or fine-tuning with your own datasets, we keep the experience cohesive—one canvas, multiple specialized agents.
