Contexta vsBuilt-In AI Tools.
Claude Projects, custom GPTs, plugins and Copilot agents are worth having. But what you build in one is locked into that platform, and platforms change.

Frequently Asked Questions
Can I use Claude Projects and Contexta together?
Yes. Keep using Projects for one-off work. Contexta adds your company context, knowledge base and shared skills, and makes them available in every AI your team uses, including Claude.
What happens to our custom GPTs?
OpenAI announced in September 2026 that custom GPTs are being retired in favour of plugins. Skills kept in Contexta don't depend on any one platform's format, so they carry on working in every connected AI.
What about Claude and ChatGPT plugins?
Plugins bundle skills, tools and connections for one platform. They're useful, but a Claude plugin doesn't run in ChatGPT, and a ChatGPT plugin doesn't run in Claude. Contexta connects to each platform, including through its own plugin for Claude Cowork, so the same skills and context reach all of them.
Do Claude skills sync between Claude's own apps?
Not always. Anthropic's documentation says custom skills don't sync across its surfaces, so a skill uploaded in one place may need uploading again in the next. Skills in Contexta are fetched from one place by every connected app.
Do we still need our Claude or ChatGPT plan?
Yes. Contexta works inside the AI plans your team already has. It supplies the skills, context and knowledge; your AI provider supplies the AI.
