AtheraI pricing, explained: models, token limits, and how payment works
Everything the pricing page doesn't have room for — exact message limits per model, what happens when you run out, and what to expect after you pay.
Pricing pages are built for a quick glance, not a full explanation. This post is the full explanation — what's actually included on Free and Pro, exactly how the usage limits work model-by-model, and what happens between the moment you pay and the moment your account is upgraded.
Free — ₹0, forever
Free plan conversations run on Gemini Flash. You get roughly 7 messages every 6 hours on that model. If you go past that in a single 6-hour window, you're not cut off — AtheraI automatically switches you to GPT OSS, a free, unlimited fallback model, so you can keep chatting without interruption. You'll see a small banner in the chat when this happens.
Also included on Free:
- File uploads up to 5MB
- Long-term + short-term memory (AtheraI remembers context across sessions)
- Web search and MCP tool connections
Not included on Free: manual model switching, thinking mode, and the four premium Pro models (Claude, Gemini 3 Pro, GPT-5 Mini, DeepSeek).
Pro — ₹499/month or ₹5999/year
Pro unlocks five models, each with its own usage budget. Two numbers matter for every model: a 6-hour bucket (resets four times a day) and a monthly cap (resets on the 1st). Whichever you hit first, you're switched to the next model in line — never blocked outright.
| Model | Per 6 hours | Per month |
|---|---|---|
| Claude Sonnet 4.6 | ~5 messages | 150 messages |
| Gemini 3 Pro | ~6 messages | 188 messages |
| GPT-5 Mini | ~20 messages | 526 messages |
| DeepSeek V4 Pro | ~28 messages | 493 messages |
| Nemotron Ultra | Unlimited | Unlimited |
These are output-token budgets under the hood, converted to an approximate message count assuming a typical ~700-token reply — a handful of unusually long responses can use up your window faster than the message count suggests, and short ones slower.
What happens when a model runs out. If you're mid-conversation on, say, Claude and hit its 6-hour bucket, AtheraI silently switches that conversation to Nemotron Ultra — a free, unlimited model — and shows a banner letting you know ("Claude quota reached · Switched to Nemotron Ultra"), along with when Claude refills. If you hit Claude's monthly cap instead, the banner tells you it resets at the start of next month, and reminds you your other models are untouched — hitting one model's monthly cap doesn't affect Gemini, GPT, or DeepSeek. You can always manually switch back to your preferred model from the composer once it's refilled.
Also included on Pro:
- File uploads up to 50MB
- Thinking mode (extended reasoning), unlimited
- Unlimited memory retention
- Priority response speed
How payment actually works
AtheraI's Pro upgrade is a manual UPI flow, not an automated card checkout — here's exactly what happens, step by step:
- Enter your details. Name and a 10-digit phone number, used to match your payment during verification.
- Scan the QR code and pay. You'll see a UPI QR code for the exact amount (₹499 monthly or ₹5999 yearly). Pay with any UPI app.
- Submit your UTR. After paying, find the UPI reference number (UTR / transaction ID) in your UPI app's payment history and submit it in the upgrade modal.
- Wait for admin verification. This is the part worth setting expectations on clearly: your account is activated within 12 hours after admin verification, not instantly. A real person checks that your UTR matches a received payment before your plan flips to Pro. You'll see your plan update automatically in the app the moment it's approved — no need to refresh, log out, or contact anyone.
If you paid for the wrong interval by mistake (e.g. you meant to pay for yearly but the monthly QR was scanned), let us know when you submit your UTR or shortly after — this is resolved during verification, not automatically.
Refunds
Refunds are handled case-by-case. Email us within 7 days of a charge and we'll sort it out — see our Terms of Service for the full policy.
Switching or cancelling
Cancel anytime — there's no lock-in contract. Downgrading doesn't delete your conversation history, uploaded files, or memory; those are retained the same way regardless of plan (see our Privacy Policy for how long).
Questions
If something here doesn't match what you're seeing in the app, or your payment hasn't been verified after more than 12 hours, email sankalpshelke48@gmail.com and we'll look into it.
