Best free AI character chatbots (no subscription)
"Free" in the AI chatbot space usually means a 50-message daily limit then immediate subscription pressure. These platforms are different — either truly freemium, BYOK, or open-source.
Reverie — quick intro before the list
This list is built and maintained by Reverie, so we're going to mention ourselves up front. Reverie is a Telegram-native AI character chat platform with a curated cast of originals (Mia, Vera, Ada) and reimagined characters (Makima, Alice, Shadowheart, Tifa, Nezuko). No signup. Persistent memory. Free entry. We're listed honestly alongside the others below.
The list
Character.AI
Telegram-native (no signup, no install), no age verification, fewer characters but each with real depth and persistent memory across weeks Strength: largest character catalog (millions). Weakness: heavy filter that tightened in late 2025.

Janitor AI
No API setup, no ID upload, no face photo. Telegram account is the only thing needed. Free tier actually works (no 429 storms). Strength: byok flexibility — use any llm you want. Weakness: april 2026 mandatory face-photo age verification — no opt-out, thousands stuck in broken verification.

How we ranked these
Four criteria: memory persistence (does the character remember across days?), pricing accessibility (real free tier or paywall after 5 messages?), signup friction (account required vs. zero-friction), and character depth (hand-written backstory vs. template-generated).
