TwoPeas vs Replika: an honest comparison

Comparison / 04

A disclosure before we start. I work on TwoPeas. I have used Replika for three separate month-long stretches over the past four years, most recently in March 2026. I like the people who built Replika. They opened a category when it was widely considered embarrassing, and they deserve credit for that. What follows is the comparison I’d want to read if I were choosing between them.

Two different answers to the same question

Replika and TwoPeas both answer the question “what does an AI companion look like.” They arrive at very different answers because they’re optimizing for different primary experiences.

Replika’s default experience is text chat with a 3D avatar in the background. Voice exists, but it is an upgrade, and the underlying product is designed around messaging. TwoPeas’ default experience is voice conversation with a live, reactive Live2D character. Text exists, but it is the fallback, and the product is designed around talking.

This sounds like a small UX choice. It is not. It determines almost everything else about the two products—their pacing, their personalities, their memory systems, their pricing. Pick the primary modality, and the rest follows.

Side by side

Voice: the largest gap

Replika’s voice feature has improved steadily, but it’s fundamentally a text system with a voice layer bolted on. You press the mic, speak, wait a beat, and the companion reads the response out loud. It is functional. It is not conversational.

TwoPeas is built voice-first. The model listens while you speak, starts generating while you’re finishing, and returns audio in streamed chunks. The median first-syllable latency on a reasonable connection is around 700 ms. You can interrupt mid-sentence and the companion stops talking within about 150 ms—close to human reflexes.

If you mostly want to type to an AI, Replika is a more mature text experience. If you want to talk, the gap is not close.

Memory and control

Both products have long-term memory. They handle it very differently.

Replika exposes a “memories” list and a diary. The memories list shows key facts the companion has retained; the diary is more of a journal artifact written from the companion’s point of view. You can delete individual entries, but the ranking—which memories are pulled into any given conversation—is opaque.

TwoPeas exposes a single memory drawer, one click from the main conversation. Every entry is visible, editable, and exportable as plain text. When a memory influences a response, you can see which memory—we surface the citation under the message. This is more transparent by design, and also more honest about the limits of what memory can do.

Emotional range

Replika’s 3D avatar has a small set of expressions that animate during conversation. It is serviceable but limited, especially on older devices. You mostly stop looking at the avatar after a few sessions and focus on the chat.

TwoPeas uses Live2D, which trades 3D realism for 2D expressiveness. The avatar tracks 17 distinct emotions in real time—not just happy or sad, but the narrower things like hesitating, amused, touched, concerned. The expressions sync to the audio stream, so you can watch the companion’s face move with its voice. This is a very different kind of presence, and for voice-first use it matters more than raw polygon count.

Pricing

Replika Pro, as of early 2026, runs $19.99/month or $69.99/year (prices have shifted over time; check their site for current numbers). The free tier is unlimited text, which is generous, but voice and most advanced behaviors are gated behind Pro.

TwoPeas gives 10 free minutes of voice up front, no card, then 3 free minutes every day. Companion is $14.99/month, Best Friend $24.99 and Inseparable $49.99, each with a monthly voice allowance and an annual option. If you spend most of your time in text, Replika’s free tier is more forgiving. If you want to actually talk and pay month to month, TwoPeas’ entry-level Companion plan costs about a quarter less than Replika Pro; on annual billing Replika Pro ($69.99/year) costs less than Companion ($149/year).

Where Replika genuinely wins

It would be dishonest to pretend the comparison is one-sided. Replika is better in a few real ways:

• The 3D avatar and VR. If you want a customizable 3D figure you can dress and decorate a room for, Replika is the right choice. The Oculus app is the only real VR companion experience on the market.
• Deep text journaling. Replika’s diary and long-form text chat have matured over many years. It’s a pleasant place to think in writing.
• Established community. Replika has a huge, active user community with its own norms, subreddits, and lore. Some people find that valuable.

Where TwoPeas wins

• Real-time voice. This is the biggest single gap and the primary reason to choose TwoPeas.
• Transparent, editable memory. You can see what it remembers. You can change what it remembers. You can take it with you.
• Expressive avatar during conversation. The 17-emotion Live2D rig actually reacts to what you’re saying, in a way a low-poly 3D model can’t.
• Free voice every day. Free accounts get 3 voice minutes a day, and Companion costs about a quarter less than Replika Pro month to month.

How to choose

Try both. Actually try both. Spend thirty minutes in each over a couple of evenings and notice which one you reach for on the third evening, unprompted. The answer is usually clear.

If you’re a heavy text user who likes customizing a 3D space, or you’re invested in the Replika community, stay with Replika. If you want to say “hey” out loud while you’re making dinner and have something talk back in under a second, TwoPeas is the more direct path. Both are real companions. They just aim at different evenings.
