CraftBot is a self-hosted, proactive AI assistant that runs locally 24/7. Unlike chat-based AI tools, it continuously works toward user-defined objectives — breaking them into tasks and initiating action rather than waiting to be prompted. Its standout feature is Living UI: custom apps and dashboards the agent builds inside CraftBot that stay aware of their own state, letting the agent read, write, and act on UI data directly. Users can import, build, or evolve Living UIs as their needs change, turning CraftBot into something between a personal agent and a self-modifying software platform. MCP integrations, Skills, and external app connections let it reach into third-party services while remaining fully local. The agent harness is MIT-licensed. CraftBot first launched on Product Hunt on April 18, 2026, earning #3 Product of the Day with 263 upvotes. Today's re-feature on Product Hunt's front page (123 votes) follows a significant update shipping the Living UI evolution system — where UIs built by the agent adapt in real time as your goals and workflows change.

Mediator.ai
Game theory + LLMs to find fair agreements both parties will actually accept

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.
Reviewer scorecard
“The Living UI concept is genuinely novel — having the agent maintain awareness of custom UI state and act on it directly blurs the line between app and agent in a productive way. Self-hosted with MCP support checks all the right boxes for privacy-conscious developers who want real automation.”
“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.”
“A 'proactive' AI running 24/7 sounds great until it's doing something you didn't intend at 3am. The Living UI concept is interesting but means you're trusting a locally-running agent to mutate your own tools autonomously. Requires careful configuration and a level of trust most users haven't earned with any AI system yet.”
“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.”
“Software that evolves its own interface based on how you actually use it is a genuinely new interaction paradigm. CraftBot is an early implementation of something much larger — the self-modifying personal software stack where apps and agents are the same thing.”
“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.”
“A proactive creative assistant that builds its own tools around my workflow is exactly what I've wanted. The Living UI concept applied to a content calendar or creative project board could be genuinely transformative for how I manage long-form projects.”
“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.”
