AI Subroutines from rtrvr.ai are a new automation primitive: you record a browser task once (a form submission, a LinkedIn connection, a CRM update), and that recording becomes a deterministic, callable tool that AI agents can invoke with different parameters — without spending tokens on every run. Unlike Playwright, Browser-Use, or other out-of-process solutions, Subroutines execute entirely inside your browser tab, inheriting your live session cookies, CSRF tokens, and signed headers automatically. The technical approach is clever. During recording, the system captures network requests and DOM interactions, then ranks captured requests to identify the actual API call (filtering out analytics and telemetry). Replay-hostile identifiers are stripped while stable endpoints are preserved. The result is a script that runs in your browser context — no session rebuilding, no key extraction, no proxy rotation needed. The AI handles parameter selection; the script handles execution. The business case is clear for outreach and operations teams: bulk LinkedIn campaigns, CRM mass-updates, scraping pipelines, and form submissions that would cost hundreds of tokens per run instead execute as cheap deterministic scripts. The model positions Subroutines as the "function call" layer beneath AI agents — the actions that don't need intelligence every time they fire.

SureThing is an AI agency platform that tackles the real bottleneck in enterprise AI adoption: not running agents, but coordinating between them and humans. The platform lets you spin up autonomous agents for roles like COO, CMO, or CTO that share a unified memory system — eliminating the information silos that kill cross-functional workflows. What's distinctive is the communication layer. SureThing agents report progress in human-readable, human-sounding language rather than raw JSON dumps or tool call logs. Plug in GitHub skills to create reusable team members, connect to 1,000+ integrations, and get SOC 2-compliant outputs that can actually be shared in executive meetings without translation. Launched on Product Hunt today at #2 with 269 upvotes, SureThing is aimed at teams that have tried running agents in isolation and found the coordination overhead defeating the productivity gains. The unified memory architecture across agent roles is the interesting technical bet here — if it works at scale, it could make multi-agent enterprises genuinely viable rather than a demo.
Reviewer scorecard
“The 'record once, replay many' pattern solves a real cost problem in agent pipelines. The in-browser execution model is clever — you get auth context for free instead of fighting with session management. This is the kind of tool that drops into existing workflows without requiring a rewrite.”
“The GitHub skills-as-reusable-agents pattern is elegant — it turns existing code into deployable team members without custom boilerplate. Unified memory across executive roles could actually solve the context-loss problem that kills multi-agent systems in production.”
“Browser automation that runs inside your session is exactly the attack surface that malicious sites exploit. Subroutines executing in-tab with full cookie access means a compromised script could do real damage. The 'zero token cost' claim also obscures that you still need LLM calls for parameter selection — the savings are real but overstated.”
“Every enterprise agent platform promises 'human-like communication' and SOC 2 compliance. Until I see a case study where SureThing agents survived six months of real company chaos — messy data, org changes, competing priorities — I'm skeptical of the production claims.”
“This is the 'compilation' step for agentic workflows — moving from 'LLM decides every click' to 'LLM selects a pre-compiled action.' That separation of concerns (intelligence vs. execution) is how you scale agent operations from one-off demos to production pipelines. The pattern will be widely copied.”
“The killer insight here is that agent coordination is the unsolved problem, not agent capability. A platform that makes agents legible to human stakeholders could be the glue layer the entire industry has been missing — this is infrastructure-level thinking.”
“For creators doing outreach, social posting, or newsletter campaigns, this is genuinely transformative. Recording a campaign action once and letting AI handle personalization at scale is the efficiency unlock that makes solo creator businesses actually viable at volume.”
“For small creative agencies trying to punch above their weight, autonomous agents handling operations while humans handle creative direction is the dream. SureThing's approach of making agents communicate like humans means less context-switching between AI and client calls.”
