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.

Task Bert is a privacy-first Mac app that acts as a local AI assistant for your iMessage conversations. It runs entirely on-device using local vector embeddings and your own API key (OpenAI or Anthropic), so your messages never touch a third-party server. The assistant can search across your message history, convert casual plans buried in conversations into calendar events and reminders, and surface follow-up nudges for conversations that fell through the cracks. The technical implementation is clean: it uses Hugging Face's nomic-embed-text model for on-device vector embeddings, meaning semantic search across your iMessage history doesn't require cloud calls. When it detects a plan or commitment in a conversation ("let's grab coffee Thursday"), it can write it directly to Apple Calendar and Reminders. The BYOK model puts the user in control — the app acts as orchestration layer, not a data holder. Task Bert targets a real pain point for heavy iMessage users: important follow-ups and plans routinely get buried in high-volume group chats or forgotten in long one-on-one threads. By running locally and integrating natively with Apple's ecosystem, it sidesteps the privacy concerns that have plagued cloud-based messaging assistants.
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.”
“BYOK + on-device embeddings is the right architecture for a messaging assistant. No cold storage of conversations, no vendor lock-in, no trust required. Using nomic-embed-text locally for semantic search is a smart call — it's fast and accurate enough for this use case without GPU hardware.”
“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.”
“Apple's iMessage privacy model creates real friction here — accessing message history requires specific macOS permissions that users are increasingly reluctant to grant after recent privacy scandals. Also, iMessage-only limits this to Apple devices, cutting out anyone running a mixed iOS/Android household. The addressable market is narrower than it looks.”
“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.”
“The local-first AI assistant is the next major product category. Task Bert is an early proof-of-concept for what happens when you give an AI agent read access to your communication history with proper privacy guarantees. As local inference gets faster, every major messaging platform will have something like this — but the indie versions will always be more trustworthy.”
“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 follow-up nudge feature alone would pay for this tool. I can't count how many creative collabs have died because someone (usually me) forgot to follow up on a message thread. Having an on-device assistant surface those forgotten conversations without sending them to a cloud server feels like a genuinely ethical approach to AI assistance.”
