Hipocampus is a new agent platform that takes a distinct approach to workplace AI: instead of ad-hoc request-response agents, it creates persistent "operators" that take ongoing ownership of specific recurring business processes. Each operator manages a workflow continuously — monitoring triggers, executing steps, handling exceptions, and reporting status — without needing to be explicitly invoked each time. Built for team use, operators in Hipocampus have memory, access to integrations (Slack, Notion, email, GitHub, CRMs), and the ability to coordinate with each other. A sales operator might own the entire deal-tracking workflow, auto-updating records, nudging reps on stalled deals, and generating weekly pipeline reports. A dev operator might own sprint health monitoring and dependency alerting. The indie team launched today on Product Hunt with 69 upvotes. The key differentiation from tools like n8n or Zapier is that Hipocampus operators can handle judgment calls and exception cases without human intervention, where traditional automation tools fail on anything outside the happy path.

Stet
Open-source macOS dictation that sounds like you, not a corporate AI

Stet is a minimalist, open-source macOS voice input app that transcribes speech and cleans it up without stripping away your natural voice. Named for the editorial term "let it stand," it's built on the principle that AI transcription should preserve your phrasing — not homogenize it into corporate-speak. The app listens locally, then optionally passes transcripts through an AI cleanup layer (OpenAI or Groq) to fix filler words and false starts. You can bring your own API key for completely free usage, or pay $6.99/month for the hosted cloud version. A Supabase backend enforces zero data retention, so nothing is stored after processing. Stet is the work of a single indie developer who noticed that every dictation tool on the market either sounds robotic or aggressively rewrites your words. At 66 Product Hunt upvotes on launch day (April 22, 2026), it's a quiet success that fills a real gap for writers, developers, and anyone who types a lot and is tired of Dragon-era dictation software.
Reviewer scorecard
“The 'persistent ownership' framing is exactly right — request-response agents are annoying to maintain because the whole context lives in the prompt you write each time. Operators that carry persistent state and own their domain are much closer to how real workflows actually function.”
“Open-source, BYOK, and local-first listening? This is how voice input should work. The Groq integration makes transcription near-instant. I've been using it for commit messages and code comments — genuinely faster than typing for longer explanations.”
“This is a fresh PH launch with minimal track record. 'Persistent AI operators that handle exceptions' sounds great in a demo — but real enterprise workflows have compliance requirements, audit trails, and escalation paths that are extremely hard to get right. Needs serious vetting before touching anything production-critical.”
“Apple's built-in dictation has gotten surprisingly good, and it's free with no BYOK setup. The 'preserves your voice' pitch is compelling but subjective — I'd want a side-by-side blind test. Solo indie developer + $7/mo hosted tier raises long-term sustainability questions.”
“Persistent agents owning process rather than being invoked for tasks is the architecture that eventually replaces a large portion of the operations workforce. Hipocampus is early, but the framing is directionally correct for where enterprise AI is heading by 2028.”
“We're entering an era where voice is the primary interface for AI-assisted work. Tools that get the human-voice preservation problem right now will have a head start when voice input becomes default. Stet's philosophy is the right one.”
“A content operator that persistently monitors publishing schedules, auto-drafts weekly updates from your notes, and nudges collaborators on missing assets would save me enormous mental overhead. The persistent ownership model makes more sense for creative workflows than manually prompting an agent each time.”
“As a writer, dictation tools that rewrite me drive me insane. Stet is the first one that feels like a scribe rather than an editor. The zero-retention policy means I can dictate client-sensitive notes without anxiety. This is the one.”
