What it does
Resk is a robust Python library designed to enhance security and manage context when interacting with OpenAI's language models. It provides a protective layer for API calls, safeguarding against common vulnerabilities and ensuring optimal performance.
Open-source LLM security stack: deployable firewall, token-level filtering, prompt-injection defense. Try the live demo or pip install resk-llm.
AI systems have access to your most sensitive data — and they remain critically vulnerable. RESK builds the open-source stack that fixes this: a deployable LLM firewall, token-level filtering engines, agent observability, and deception for AI scanners. Prompt filters are jailbreakable. Post-hoc moderation acts too late. RESK enforces security where no injection can reach: inside the generation loop. A 64-bit capability system per user — tools, code gen, DB access, PII, email — enforced at the token level. The resklogits engine (ShadowBan + Aho-Corasick) makes dangerous content physically ungeneratable. GPU-accelerated. Users, roles, policies, providers, sessions, audit logs, and a D3 graph…from resk.fr

Tapflow 2.0▲1,125We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
