ExpertAgent

Stop starting every AI chat from zero.

ExpertAgent is a native iOS app that helps you build polished expert system prompts — then copy them into ChatGPT, Claude, Gemini, or any AI chat you already use. It is not a chatbot. It is your prompt workshop: define role, experience, expertise, and tone once, and reuse that context every time.

Whether you are tired of generic answers, re-explaining your background, or inconsistent AI tone, ExpertAgent turns a quick setup into a reusable expert persona you control.

KEY FEATURES

• Expert Builder — A guided 5-step wizard: role, experience, expertise tags, tone, and special instructions. AI crafts a ready-to-paste system prompt from your inputs.

• One-tap copy — Copy the full prompt and paste it as custom instructions, a system prompt, or your opening message in any AI app.

• My Experts library — Save, search, edit, and organize experts on your device. When signed in, your library syncs for backup and cross-device access. Saved experts remain available offline.

• Explore — Browse official expert templates and community experts from other users. Like, save, and copy prompts you find useful.

• Categories and tags — Filter by field so you can find or build the right persona fast.

• Sign in with Apple or email — A secure account keeps your library backed up and unlocks community features.

• ExpertAgent Pro — Unlimited saved experts, extended daily AI for building prompts, publishing to Explore, Pro-only tones, and markdown export.

BENEFITS

• Get specific answers instead of generic tips — Your prompt encodes real role, experience, and domain context.

• Never repeat your background — Paste once per chat, not every session preamble.

• Consistent expert voice — Lock in tone so the AI stays aligned with how you want to work.

• Faster workflow — Build once, copy often. Official templates help you start even faster.

• Works with the AI tools you already use — No need to switch chat apps.

WHO IS IT FOR?

ExpertAgent is built for professionals, founders, creators, students, and power users who rely on ChatGPT, Claude, Gemini, or similar tools daily. If your work needs domain depth, structured prompts deliver better results than blank chats.

Creators who want to share useful persona prompts can publish to Explore with ExpertAgent Pro.
