Frequently asked questions about OH cards online and Terra
What are metaphorical associative cards (OH cards)?
Metaphorical associative cards (OH cards) are decks of pictures with various images, characters and metaphors used by psychologists, coaches and art therapists as a projective tool. The client picks a card, describes their associations, and through the image surfaces hidden feelings, resources and decisions. The first deck (OH-cards) was created in 1975 by Ely Raman and became a psychological tool in 1985.
How do I work with OH cards online on Terra?
Sign up at terra.support, choose a built-in deck or upload your own, create an exercise with instructions for the client, and send them the link. The client completes the exercise on their device and leaves comments on the cards. You see the result in your dashboard and work with it in a live session or asynchronously.
Is Terra suitable for online sessions with clients?
Yes. Terra was built specifically for online work: there's no need to show cards through a webcam or rent a room. The client sees cards in their own browser, can move, sort and comment on them. Both synchronous sessions and asynchronous homework are supported.
Who is Terra for?
Psychologists, psychotherapists, art therapists, coaches, business trainers and social workers — anyone who uses OH cards as a tool in individual and group work with clients.
Can I upload my own OH card decks?
Yes. The Specialist plan allows 2 custom decks; the Pro plan allows unlimited. Uploaded decks work in sessions exactly like built-in ones.
How much does Terra cost?
There's a free plan (2 exercises per month, 5 basic decks). Paid plans: Advanced — $2.99/month (5 exercises, 15 decks), Specialist — $4.99/month (same + 2 custom decks), Pro — $10.99/month (∞ exercises, 40+ decks, ∞ custom decks). Prices in your local currency are shown live on the pricing section.
Can I run group sessions with OH cards online?
Yes. Each participant sees the cards on their own device and leaves comments; the facilitator sees combined results and can discuss them in the session.
How is Terra different from other online OH card platforms?
Terra combines three key capabilities: uploading custom decks, an exercise builder with descriptions, and asynchronous client work without a live video session. Plus saved results and analytics. This covers both online sessions and homework between meetings.
Are OH cards suitable for coaching and art therapy?
Yes. OH cards are a universal projective tool: used in psychotherapy, coaching, art therapy, career counseling, corporate training and work with children. On Terra you can pick or build a deck for any specific method.
