Answer

Which is free? For chatting with an AI yourself, ChatGPT, Claude, and Gemini all have free tiers (capped by message volume and model access). For a chatbot on your own website, AnveVoice has a genuinely free tier: $0/month with 50,000 tokens included, voice + text, 50+ languages. Which is unlimited? Be skeptical of the word — almost no AI chat is truly unlimited. 'Unlimited' plans are typically rate-limited (a cap per hour/day), fair-use capped (throttled if you greatly exceed normal use), or limited to a smaller/faster model. The honest way to compare is by how the limit is expressed and whether it resets: a transparent token or message cap (like AnveVoice's 50,000 tokens) tells you exactly what you get, whereas 'unlimited' often hides a throttle. So: if you want free, the consumer assistant free tiers (for personal chat) or AnveVoice's free tier (for your website) are the picks; if you want 'unlimited,' read the rate-limit fine print, because the practical ceiling is what actually matters. AnveVoice's paid plans are flat ($39 Growth / $129 Scale) rather than per-message, so heavy use doesn't generate a per-conversation bill.

Detailed Explanation

'Which AI chat is unlimited' and 'which is free' get asked together, so here are both answers plainly — and why 'unlimited' deserves scrutiny. Which AI chats are free (and what 'free' covers). For talking to an AI yourself: ChatGPT (OpenAI), Claude (Anthropic), and Gemini (Google) each offer a free tier. What's free is personal conversational access, capped by how many messages you can send in a window and by which model the free tier lets you reach (the most capable models and longest context are usually paid). For a chatbot on your own website — answering your visitors — those consumer assistants don't apply; you want a website-chatbot free tier. AnveVoice's is $0/month with 50,000 tokens included, supports voice and text in 50+ languages, and installs with one line of code. (For a fuller comparison, see the best free AI chatbots roundup.) Why 'unlimited' almost never means unlimited. Running an AI chat costs real compute per message, so a genuinely uncapped service would be expensive to offer without limits. In practice, 'unlimited' plans use one of three mechanisms: (1) rate limits — you can send a lot, but only so many per hour or per day; (2) fair-use policies — normal use feels unlimited, but heavy outliers get throttled or flagged; or (3) model gating — 'unlimited' applies to a smaller or faster model, while the top model stays metered. None of these are scams; they're how providers keep the lights on. The point is that the marketing word 'unlimited' tells you less than the actual rate limit does. The honest way to compare: look at the cap, not the adjective. A transparent, stated limit is more useful than 'unlimited.' AnveVoice states its free cap directly — 50,000 tokens — so you can estimate how many conversations that covers. When you see 'unlimited,' find the rate-limit or fair-use clause; that number is your real ceiling. A clearly stated cap you can plan around beats an 'unlimited' plan that throttles you mid-task. Free vs unlimited — don't conflate them. They're different axes. 'Free' is about price ($0). 'Unlimited' is about volume (no usage cap). A plan can be free-but-capped (most free tiers, including AnveVoice's 50,000 tokens), paid-but-high-volume, or 'unlimited'-but-rate-limited. Decide which axis you actually care about: if it's price, pick a free tier; if it's high volume, compare the real rate limits and the cost of removing them. What this means for a website chatbot specifically. If you're putting AI chat on your own site, per-message or per-conversation pricing is the thing to avoid — it makes success expensive. AnveVoice's paid plans are flat (Growth $39/month, Scale $129/month), so a high-traffic month doesn't generate a usage bill; you get predictable cost instead of an 'unlimited' asterisk. Combined with the free $0 tier, you can start at no cost and scale to a flat fee — no per-message metering at any step. Bottom line. No mainstream AI chat is truly unlimited; the useful question is how the limit is expressed and whether it fits your use. For free, use a consumer assistant's free tier (personal chat) or AnveVoice's free tier (your website). For 'unlimited,' read the rate-limit fine print — and if it's for your website, a flat-priced plan gives you predictable cost without per-message surprises.
