Use Case Recommendations
Best for: CollieAi
CollieAi is a security proxy that sits in front of an LLM application and filters both the prompts going in and the responses coming out. Adoption is deliberately trivial: you change the base_url on your existing OpenAI-compatible or Anthropic-native client and keep every other line of code, so there is no SDK to adopt and no architectural change. Behind that one line it runs a three-layer detection pipeline — deterministic pattern matching, machine-learning classifiers, and a generative model that reasons about intent — across nine rule types. The threats it names are the practical ones: direct prompt injection and the indirect kind that arrives inside a RAG document or a tool result, jailbreak and safety-bypass attempts, PII and financial-data leakage, exposed secrets matched by shape (sk-, ghp-, AKIA, JWT), malicious or obfuscated URLs, base64-hidden payloads, Unicode evasion via homoglyphs and zero-width characters, and unsafe or off-policy model output. It runs in three shapes — drop-in proxy, real-time SSE streaming, and async jobs — and in either Monitor mode, which logs without blocking, or Enforce mode. Operationally it provides a real-time dashboard with logs, analytics and threshold alerts, SIEM export and a full audit trail. It can be run as cloud SaaS, self-hosted or on-premise, with an open-source core.
Ideal use cases:
- •Teams or individuals who need one-line adoption: point base_url at collieai, keep your existing client
- •Teams or individuals who need three-layer pipeline — patterns, ml classifiers, generative intent reasoning
- •Teams or individuals who need filters input and output across nine rule types, monitor or enforce mode
- •Teams or individuals who need catches indirect injection via rag documents and tool output
- •Anyone focused on llm-security workflows
- •Anyone focused on prompt-injection workflows
Best for: Mimiri Notes
Mimiri Notes is an end-to-end encrypted note app that treats encrypted sharing as a first-class feature rather than an enterprise add-on: you can share a single note or a whole branch of the tree with several trusted people, and every change inside that subtree syncs between participants while staying decryptable only by them. Everything is AES-GCM-256 encrypted on your device before it leaves, so neither the vendor, its servers nor your ISP can read it, and the whole codebase is open source under GPLv2 so the security claims are inspectable. The organising model is a tree with no distinction between folders and notes — any note can hold both content and sub-notes, nesting without limit, with search to narrow the tree quickly. Practical hardening goes further than most: a PIN code gates the running app, the window hides itself from screen-sharing software to prevent accidental exposure, passwords are hidden from onlookers and cameras, and the app can auto-lock after a period of disuse. Clients exist for Windows, Linux, macOS, Android, iOS and the web, all syncing in real time with a local offline copy and automatic conflict resolution. The free tier is explicitly not a trial. The company behind it is innonova GmbH, and downloads are published for every supported platform alongside a browser client that needs no install at all.
Ideal use cases:
- •Teams or individuals who need aes-gcm-256 encrypted on-device before anything is uploaded
- •Teams or individuals who need share a single note or a whole subtree, still end-to-end encrypted
- •Teams or individuals who need hidden from screen-sharing software; pin lock and auto-lock
- •Teams or individuals who need open source under gplv2 with clients for six platforms
- •Anyone focused on encryption workflows
- •Anyone focused on notes workflows
