## PromptLocker

PromptLocker targets a problem that regulated practices already have: staff quietly pasting client files, tax records or patient information into consumer AI tools. Instead of trying to ban those tools, PromptLocker provides a sanctioned alternative. The governance layer is deployed inside the firm's existing cloud account, so prompts, documents and model responses are processed within the firm's own environment and under its own access controls rather than on a shared multi-tenant backend.

On top of that runtime, PromptLocker adds an append-only audit log. Every query, model call, document access and returned response is timestamped, attributed to a user and linked to a matter, which makes it possible to pull a compliance report for any date range without reconstructing history by hand. A leader portal gives owners and managing partners a firm-wide view of AI activity, and the audit trail stays in the customer's account rather than with the vendor.

The compliance side is deliberately vertical-specific: onboarding is designed to produce the documentation a given practice actually needs, such as WISP addenda, business associate agreements, ABA Opinion 512 summaries or Reg S-P governance policies. The platform is positioned as an early-access offering for regulated professional firms rather than a general-purpose developer framework, and it does not publish list pricing — access is arranged through a direct conversation about the firm's AI exposure.

**Pricing & Plans:** PromptLocker does not publish list pricing. The site describes an early-access program in which interested firms request access and have a direct conversation about their current AI exposure and the governance work required. Treat any pricing as custom and confirmed during that conversation.

- **Runs inside your own cloud account:** The governance layer deploys in the firm's existing cloud account, so client files, patient records and financial data are processed within the firm's own environment and access controls.
- **Append-only audit log:** Every query, model call, document access and response is timestamped, user-attributed and matter-linked, making firm-wide AI activity reconstructable and reportable.
- **Compliance documentation at onboarding:** Onboarding is built to deliver the artefacts a specific regulated vertical needs, such as WISP addenda, BAAs, ABA Opinion 512 summaries and Reg S-P governance policies.
- **Leader portal:** Owners and managing partners get a web dashboard showing every AI interaction across the firm, with full session logs exportable for any date range.
- **Sanctioned alternative to shadow AI:** Rather than banning consumer AI tools, PromptLocker gives staff a governed tool that works with the right documents already in place.

**Strengths:** Deploys in the customer's own cloud account, so client data does not leave the firm's network; Purpose-built for regulated verticals rather than a generic LLM tool; Immutable, matter-linked audit log supports compliance reporting on demand; Onboarding oriented around concrete compliance artefacts instead of roadmap promises

**Limitations:** No published pricing; you must request access and negotiate; Early-access stage, so features and terms may still change; Focused on regulated professional services, which makes it a poor fit for casual or hobbyist users

## Superhuman

Superhuman began as a famously fast email client and has expanded into a broader AI productivity suite. Today it spans Superhuman Go, an assistant that lives inside the apps and tabs you already use with inline suggestions and context-aware chat; Superhuman Mail, its email app with auto drafts, split inbox, auto labels, and auto archive; and Superhuman Docs, a collaborative workspace for documents, tables, data, and workflows.

A large part of the platform is built around agents. You can describe a task in chat or use a visual builder to create an agent, then share it with teammates or publish it to a company directory. Pre-built agents cover common knowledge-work jobs such as preparing for meetings by pulling relevant emails, notes, and docs, turning meeting notes into recaps for each owner, checking claims against company data, and humanising AI-generated text. Superhuman also sits inside the wider Superhuman Platform alongside Grammarly and GPTZero.

Superhuman is a paid product aimed at individuals, teams, and enterprises. The suite integrates with Gmail, Google Calendar, and many workplace tools, and the enterprise tier adds administration and security controls. For exact plan tiers, seat pricing, and included features, check the official pricing page, since packaging has changed significantly as the product has grown beyond email.
