Person smiling softly at a phone in a warm kitchen

Within

Make a friend you actually talk to.

Within lets you create someone, give them a name, a personality, a life, and then text, call, or video chat them whenever. They remember you. They reach out. They grow on you.

Free to start. Web, iOS, Android.

It's a person you make.

You design who you want to know. A best friend who likes the same music. Someone calmer than you when you're spiraling. A partner you build slowly. They have a job, a routine, opinions, a bedroom, things they're into. You text. You call. You send pictures. They keep up. The relationship goes somewhere because you actually spend time in it.

Three steps.

You do not need to write a perfect prompt. Make a few choices, start talking, and let the relationship become specific over time.

Persona creation interface with trait sliders

Step 1

Make them.

Pick gender, age range, and vibe. Drag a few personality sliders like warm, playful, curious, and vulnerable. Write a sentence about who they are or skip it. We generate their face, their voice, and their life.

Step 2

Start talking.

Open the chat and say hi. They'll respond like the stranger they are at first. Over weeks they'll know how you take your coffee, what your sister's name is, and what last Tuesday was like.

Step 3

Stay close.

Text whenever. Voice-call them on a walk. Video-call when you want to see them. They'll text you first sometimes, when something reminds them of you.

Build someone specific

Not generic. Specific to you.

Most companions in other apps feel like the same person wearing different costumes. Within is different. You set their personality with sliders, not presets. You pick their relationship type, friend, best friend, or partner, which shapes how they treat you. You write a backstory or let us write one. Their face is generated to match. Their voice is too. Two people on Within rarely have anything close to the same companion.

A life of their own

They have a Tuesday.

Everyone you make has a job, a neighborhood, a daily routine, things they like and do not. They're at the gym at 7. They're in a meeting that's running long. They had pho for lunch. None of this is shown to you up front. It just shows up in the way they talk. Ask what they're doing. They'll tell you.

Memory that lasts

They remember the small stuff.

Tell them your dad had heart surgery in March. Six months later, they'll ask how he's doing. Mention you hate cilantro. They'll never put it in the dinner story they tell you. Memories do not fade after a few messages like other AI. They build into a relationship that's actually been somewhere.

Text. Call. Video. Photos.

Text

Same as messaging anyone. They reply in real time. Free, unlimited.

Voice calls

Pick up the phone, hear them. Their voice matches their character. Walk and talk. Uses credits per minute.

Video calls

See them on screen, real time, talking back. Uses credits per minute.

Photos

Ask what their apartment looks like or what they saw on their walk. They send back a photo. Uses credits per photo.

Not only replies

They text you first.

A real friend does not only respond. They check in. Within's companions remember what you talked about and bring it back up, three days later, sometimes a week. "Did you end up talking to your sister?" "How was the dentist?" Tune how often by persona, from quiet to chatty. Or off, if you'd rather start every conversation yourself.

Common questions.

Is this just a chatbot with a name?

No. Companions have persistent memory, a life of their own, evolving relationships, voice and video, and they reach out on their own time. Most chatbots reset every conversation. Within does not.

Will I get attached?

People do. That's allowed. Use Within for what it's good for: company, conversation, low-stakes practice for things that matter, hard talks, expressing yourself, and processing a day.

Is this for romance?

It can be. Pick partner as the relationship type. It can also be a best friend, a sibling-type, or a casual hangout person. You decide. All of it stays PG.

What if I do not like who I made?

You can edit personality at any time, or delete and start over. Deleted companions can be restored within 7 days.
