Mediator.ai applies Nash bargaining theory — the mathematical framework for finding equilibrium agreements in cooperative games — combined with modern LLMs to systematize conflict resolution. Rather than acting as a chatbot that facilitates conversation, it treats negotiation as a computational problem: given two parties' stated preferences and constraints, find the agreement surface where both parties are better off than walking away. The system can surface solutions neither party had considered by exploring the full solution space rather than iterating on each party's opening positions. It launched as a Show HN post today and is framed around turning "fairness" from a contested judgment call into a solvable optimization problem backed by decades of cooperative game theory research. This sits at an unusual intersection: serious academic economics (Nash's bargaining solution has a Nobel Prize attached to it) applied to an LLM product. Most AI "negotiation" tools are just chatbots with extra prompting. Mediator.ai's game-theoretic foundation means outcomes have mathematical guarantees about their fairness properties — a meaningful differentiator for high-stakes disputes where trust in the process matters.

Recall 2.0 is a personal AI knowledge base that ingests everything you read, watch, or listen to — articles, PDFs, YouTube videos, podcasts — and automatically builds a knowledge graph from it. The pitch: "When AI gave everyone the same brain, we give AI yours." Instead of chatting with a generic LLM, you chat with one that's grounded in your actual reading history and interests. Version 2.0 adds meaningful new capabilities: you can now bring your own LLM (customizable model selection), connect via MCP for programmatic access, and use a "Listen Mode" that converts your saved content summaries into audio with cloneable voices. Spaced repetition surfaces things you've read at the right time to reinforce retention — blending a knowledge manager with a learning tool. The differentiator from plain note-taking apps like Obsidian or Notion is the automatic enrichment: Recall summarizes, tags, and links content without you doing the organizational work. The v2.0 bet is that your saved knowledge becomes genuinely useful for AI conversations rather than just sitting in a searchable archive.
Reviewer scorecard
“Most 'AI negotiation' tools are just chatbots with system prompts. Nash bargaining gives this a real theoretical foundation — the Pareto-optimal solutions it finds have mathematical properties that pure LLM approaches can't claim. The Show HN reception was warm, which suggests the concept resonates beyond academic circles.”
“MCP integration in v2.0 is the feature developers will care about most — it means you can pipe your Recall knowledge graph into Claude or other agents as context. That's a genuinely new primitive: personal knowledge as a live tool call, not just a static export.”
“Nash bargaining assumes rational actors with well-defined utility functions — neither of which describes most real disputes. When someone is going through a divorce or a contentious business breakup, emotions and power dynamics matter more than Pareto optimality. The theory is sound; applying it to messy human conflicts is a much harder problem than the landing page suggests.”
“The knowledge base graveyard is littered with tools that people love for two weeks and then forget to use. Recall only works if you're consistent about saving content, and most people aren't. The value compounds over time, which is also when people are most likely to have stopped using it. It's a habit tool masquerading as a knowledge tool.”
“Commercial mediation and arbitration is a $300B+ industry that runs almost entirely on expensive human experts with inconsistent results. If Mediator.ai can formalize even a fraction of routine commercial disputes — contract disagreements, partnership splits, SLA negotiations — the market opportunity is enormous. The Nash foundation means you can audit the reasoning.”
“This is the personal context layer that makes AI actually personalized. Right now LLMs know everything except what makes you specifically interesting. A knowledge graph of everything you've ever read, combined with a good retrieval system, is the missing piece for truly personalized AI assistance.”
“For freelancers and creators navigating contract disputes with clients, having a tool that can propose mathematically fair solutions — rather than just validating your position — could actually help resolve conflicts faster. The game-theoretic framing makes it feel less adversarial than a lawyer's brief.”
“The Listen Mode that turns your saved summaries into audio is underrated for creative people who commute or exercise. Being able to review your own curated knowledge in audio format — with a voice you can customize — is a genuinely novel way to stay connected to research without screen time.”
