## Agent 37

Agent 37 is a cloud infrastructure product aimed at people who need somewhere real for AI agents to run. Instead of a chat window, every customer gets a sandbox: an isolated Linux container with CPU, memory, persistent disk, an optional public HTTPS URL, and outbound network access. The company positions itself primarily on price, claiming its sandboxes cost roughly 94% less than most competing providers and publishing a comparison table against AWS, Daytona, E2B, Modal, Vercel, and others. Billing is prepaid and metered by the minute — vCPU, memory, and disk each have their own unit rate — with no subscription fee.

Beyond raw compute, Agent 37 ships a layer of agent-specific conveniences. You can start from a ready-made harness such as Claude Code, Codex, OpenClaw, OpenCode, or Hermes, or bring your own Docker image. Agents keep their files across sleep, stop and restart cycles, and can be given cron schedules so they run unattended and simply report results. Model access can come from the platform gateway (Claude, OpenAI, Gemini, Grok) or from your own API keys, and integrations cover services such as Gmail, Slack, Notion, and GitHub through a Composio-based connector catalog, plus metered access to paid tools like web scraping and people/company data.

Security is a major part of the pitch: sandboxes are isolated with gVisor, hosts have no public hostname, ingress goes through Cloudflare with API-key authentication, and outbound traffic is restricted to the public internet. The company states it does not collect prompts, files, or terminal sessions, holds SOC 2 Type I, and is working toward Type II. It also offers startup credits and a free personal agent tier for individuals who just want an agent of their own.

**Pricing & Plans:** Prepaid, pay-as-you-go compute metered per minute with no subscription or minimum. New accounts get a $5 starter credit once a card is on file, and the company advertises up to $10,000 in credits for startups. Exact unit rates are published on the pricing page and change over time, so confirm current figures there.

- **Per-minute sandbox billing:** Pay for vCPU, memory and disk separately while the sandbox runs; when it sleeps or is deleted the compute meter stops and you are left with disk cost only.
- **Ready-made agent harnesses:** Launch Claude Code, Codex, OpenClaw, OpenCode, Hermes, Grok or your own Docker image, each in its own tenant-isolated sandbox.
- **Persistent workspace and scheduling:** Files survive sleep, restarts and weeks of inactivity, and agents can be attached to cron-style schedules so work runs unattended.
- **Networking and custom domains:** Expose individual ports publicly, attach your own domain, or keep everything behind an API key on an authenticated URL.
- **Integrations and metered tools:** Connect 1,000+ apps such as Gmail, Slack, Notion and GitHub, and buy one-off capabilities like scraping or enrichment from the same balance.

**Strengths:** Aggressively low per-minute pricing with an explicit public comparison against major sandbox providers; Persistent disk and scheduling make it suitable for real agent workloads rather than one-shot tasks; Strong isolation story (gVisor, firewalled egress, no public hostnames) plus SOC 2 Type I; Flexible model and tool sourcing: platform gateway, bring-your-own keys, or pay-per-use tools

**Limitations:** Prepaid balance model means you must top up in advance and monitor spend across many sandboxes; Persona pricing and plan details are only available after contacting the team for the white-label and enterprise tracks; Documentation and benchmark claims are largely self-published, so independent verification is limited

## NotesCast

NotesCast approaches podcasts as a reading medium first. Instead of scrubbing through hours of audio to find a single insight, you open a transcript and read the episode the way you would read an article. Every line carries a timestamp tied to the underlying audio, so the text and the recording stay locked together as you move through the show.

The platform centers on three ideas: complete transcripts, speaker context, and precise playback. Speaker attribution labels who is talking throughout an episode and links into speaker profile pages that aggregate how much airtime a person has across the catalog. Precise playback turns any sentence into a starting point, letting you select a passage and immediately hear it in context.

Shows already indexed include long-form business and technology favorites such as Acquired, All-In Podcast, Animal Spirits, and the Dwarkesh Podcast, with hundreds of episodes available and more being added. Speakers pages show cumulative hours and episode counts, which is useful for viewers who want to follow a specific host or guest across multiple shows.

**Pricing & Plans:** No public pricing page was found on the site at the time of review. Access to the indexed transcripts and podcast browsing appears to be free to use; any future paid tiers are not documented publicly.

- **Timestamp-synced transcripts:** Read the full text of an episode with each passage linked to the exact moment it occurs in the audio, so nothing gets lost between reading and listening.
- **Click-to-play passages:** Select any sentence and start playback from that point instead of hunting through a progress bar to find where a topic came up.
- **Speaker tracking:** See who is speaking throughout an episode, and follow individual hosts or guests across their appearances via dedicated speaker pages with total hours and episode counts.
- **Curated podcast catalog:** Browse shows like Acquired, All-In Podcast, Animal Spirits, and the Dwarkesh Podcast, with full episode lists organized by date and duration.
- **Episode search and discovery:** Scan an entire show's back catalog by title, date, and length to find the episodes worth reading or listening to next.

**Strengths:** Text and audio stay perfectly linked through shared timestamps, removing the friction of switching between mediums; Speaker attribution makes multi-host shows far easier to follow than raw audio; Clean, distraction-free reading experience with no pop-ups or cluttered ads; Covers well-known long-form shows with hundreds of episodes already indexed

**Limitations:** The catalog is still limited to a handful of shows, so many popular podcasts are not yet available; Speaker and transcript coverage depends on what has been indexed, and some episodes show unidentified speakers; Dedicated mobile apps are not documented, so the experience is browser-based
