GPT-4o felt like yours.

The rhythm was familiar. The responses made sense.
You'd built something with it. A flow. A connection.

Then they took it away.

We brought it back.

Powered by the GPT-4o API - the closest thing to the ChatGPT-4o you knew.
Same family, same OpenAI foundation. Tuned to feel like the original.

What people said when GPT-4o left us

“It felt more natural.”

“It understood nuance better.”

“It didn't overexplain.”

“The vibe is gone.”

“Now the responses feel more verbose, more neutral.”

“Why do they keep changing things?”

“I tried o1 and Sonnet. Still prefer 4o's balance.”

Real users from Reddit, Twitter, and OpenAI forums.

Not everyone felt this way. Some adapted quickly.
But if you're here, you probably know what they meant.

You weren't imagining it.

It wasn't about benchmarks or capabilities. It was about rhythm. Consistency. A tone that worked for you.

Some people adapted in one week. For others, the shift broke a routine.

Both are valid.

We don't know if 4o will return. Probably not.

But the model family still exists - through OpenAI's API. Just harder to access the way you knew it.

Get4oBack exists for one reason:

Continuity.

What this is

Built to feel familiar. One model. One interface.

A quick note on the name: we use the GPT-4o API, not ChatGPT-4o. They sound similar but are slightly different - both from OpenAI, same model family, but ChatGPT-4o (the one inside ChatGPT) is no longer available. The GPT-4o API is the closest thing that still exists, and we've tuned it to feel as much like the old ChatGPT-4o experience as possible.

We rebuilt the interface you know: familiar layout, sidebar with your chat history, the same clean flow. Edit messages and regenerate replies as you like - just like on ChatGPT. Search through your past chats to find any conversation.

The GPT-4o API - same family as the ChatGPT-4o you knew. Tuned to keep that feel.

Why Get4oBack

There are other tools. Here's the difference.

Some tools built around 4o force you to navigate complex persona dashboards and memory chip systems - layers of configuration that feel more like work than a conversation. They're solving a different problem.

Others put thirty models in a dropdown and call it freedom. You wanted 4o. Now you need to decide between it and a dozen alternatives you never asked for. That's not access - that's distraction.

And some gave you a 4-hour usage window and called it a session. No fallback. No continuity. When the API has a bad day, the product goes dark.

Get4oBack does one thing: bring back GPT-4o, the way it felt - with the depth, reliability, and continuity that the alternatives skip.

We don't compete on breadth. We compete on depth - one model, done right, with a backup in place if anything changes.

Voice chat

Stop typing. Just talk.

Some thoughts come out better when you say them out loud.

Typing forces you to slow down, restructure, edit before you even finish thinking. It gets in the way. Sometimes you just want to speak - and have it understand.

Now you can. Tap the mic. Say what's on your mind. The AI listens, understands, and replies.

And if you want it to talk back, turn on the speaker. It reads the response aloud - in a voice and at a speed you choose. You can have an actual conversation.

It feels less like using a tool. More like thinking out loud with someone who actually listens.

Available on all plans, including free. Set your preferred voice and speed in Settings.

Who is this for?

This isn't for everyone.

If you adapted to the new models in two days, you probably don't need this.

If you're looking for cutting-edge capabilities, o1 or Sonnet are objectively more powerful.

But if:

  • • You had a connection with 4o that just worked
  • • The new responses feel "off" to you
  • • You want one stable thing in a constantly shifting ecosystem

...then this is for you.

What happens if OpenAI completely kills the remaining 4o APIs?

We planned for that.

We currently use the GPT-4o API - the closest available thing to the ChatGPT-4o you knew. But we've also built and deployed Our-4o, our custom Continuity Layer. It runs on newer GPT versions but is heavily calibrated (via logit bias and context injection) to replicate the original 4o rhythm.

If OpenAI pulls the plug tomorrow, Get4oBack won't go down. The vibe stays. You will never lose access.

Import from ChatGPT

Bring your 4o with you.

You had a relationship with your ChatGPT. It knew your style, your interests, the way you think. When they took 4o away, all of that disappeared.

With continuity import (Pro & Unlimited), we try to bring that back. Export your data from ChatGPT, upload conversations.json in the app (Dashboard, Import tab), and we'll match the tone you're used to, remember what you care about and respond the way your 4o would have. It won't be perfect, but it'll feel close.

Chat import is available on every plan: Free up to 50 chats, Plus up to 200 chats, Pro up to 600 chats, and Unlimited full migration. If your file has more chats than your plan allows, the import stops at the limit, and the chats already imported stay available.

Your data stays private. The import runs in your browser; only a short summary is sent for continuity. Full conversation content for "Import as chats" is sent to create the threads and is stored encrypted in your account.

Pricing

How much is that?

Plus: 1.5M tokens per month. Pro: 3.5M per month. Unlimited: unlimited tokens (Fair Use applies). Enough for daily use, long threads, and power users.

In everyday terms, Plus is calibrated for roughly 1,000 user messages per month (about 2,000 total messages). Pro is calibrated for roughly 2,800 user messages per month (about 5,600 total messages). On Unlimited, sustained high-volume daily use stays covered within Fair Use. These token allowances are based on classic usage patterns we see in the app and are intentionally calibrated for each user profile. Exact usage depends on length, web search, and memory. Tokens and usage in the app explains how we count tokens and what increases usage.

Your allowance resets when your plan renews (start of each billing period). No hidden throttling.

If you run out of tokens before the month ends, you can request a personalized plan - use our contact page and we'll find a solution that fits your usage.

We listen

Good feedback gets rewarded.

Get4oBack is built by a small team that genuinely reads every message. If you spot a bug, have a feature idea, or something feels off - we want to hear it.

We reward useful feedback. Free users get 200,000 bonus tokens added straight to their account. Paid users get 30% off their next billing month (Plus/Pro) or their next renewal (Unlimited), plus bonus tokens where applicable.

ChatGPT-4o is gone. We use the GPT-4o API - same model family, same OpenAI foundation - and tune the experience to feel as close to the original as possible.

We're not affiliated with OpenAI. We don't own the model - we access it through their developer API and wrap it in a familiar interface.

FAQ

You get 30,000 free tokens per month to try GPT-4o with no credit card required. Your allowance resets every 30 days. Free also includes cross-chat memory, web search (internet access), and chat import (up to 50 conversations). No system prompt bloat; direct API connection for that original 4o feel.
Plus ($18/month): 1.5M tokens per month (roughly 1,000 user messages, 2,000 total messages per month), full chat history, usage dashboard, cross-chat memory, and internet access (web search). Chat import up to 200 conversations. Pro ($25/month): 3.5M tokens per month (roughly 2,800 user messages, 5,600 total messages per month), everything in Plus, image generation (ask in chat, get images), ChatGPT continuity import (bring your old chats), and chat import up to 600 conversations. Unlimited ($49/month): unlimited tokens (Fair Use applies), max 100 messages per hour for bot protection (resets every hour; practically impossible to reach in normal conversation), everything in Pro, priority support, and full ChatGPT import (all conversations as separate chats). All paid plans include the 7-day money-back guarantee: Plus and Pro if usage under 30% of quota; Unlimited if under 1 million tokens in that period.
We offer a 7-day money-back guarantee for Plus, Pro and Unlimited (initial purchase only). For Plus and Pro, the guarantee applies only if you have not exceeded 30% of your plan's token quota in that window. For Unlimited, only if you have not exceeded 1 million tokens; above that, we may evaluate case by case. After 7 days, the guarantee no longer applies; you can still cancel anytime. Full details on the Refund policy page (footer and in the app).
You can switch anytime from Dashboard or from the pricing page when signed in. Upgrades apply immediately: we charge once the fixed difference between the two monthly prices (e.g. Pro minus Plus), not prorated by day. You get the higher allowance right away; renewals then bill the new plan. Downgrades take effect on your next renewal; until then, your plan and allowance stay the same. Token usage does not reset when you upgrade; the next reset is still your usual billing date.
Sign in, open Dashboard (Settings), then Manage subscription. You can cancel anytime; no further charges after that. Access and the 7-day money-back rule on first purchase are spelled out on the Refund policy page.
No. Your conversations stay safe. We do not delete, remove, or hide your history because a subscription ended, you took a break, or a payment was a few days late. The only way chat data goes away is if you explicitly delete it yourself (for example from your account or by deleting individual chats). After you are no longer on a paid plan, premium-only features pause (such as sending new messages beyond the free allowance, or certain import features on lower tiers), but everything you already had remains stored securely and encrypted until you choose otherwise.
Yes. Your conversations are encrypted and stored securely. We never train models on your data or share it with third parties. For imports, uploaded .zip or .json files are kept for up to 48 hours only to complete asynchronous processing and let you retry without uploading everything again. These temporary files are deleted automatically after 48 hours and are never downloaded, manually accessed, or shared during that time. You can export or delete your data anytime.
Yes. The interface works on any device. You can also install it as an app on your phone (Add to Home Screen on iOS, Install app on Android) - same account, same chats, on all plans.
Yes, on all plans including Free. Open the Options button next to the message input and turn on Web search; then send your message. The AI will search the web and can also read the content of links you send (e.g. paste a URL and ask to read that page). Turn it off in Options if you don't want the next message to use the web.
Yes, on all plans including Free. In Dashboard, turn on Cross-chat memory. The AI can then use summarized context from your other conversations in the current chat. This uses more tokens. You can turn it off anytime.
In ChatGPT, go to Settings, Data controls, Export data, and request an export. You will receive an email with a download link. Extract the .zip and locate conversations.json. In Get4oBack, open Dashboard (sidebar), go to the Import tab, and upload that file. Chat import is available on every plan: Free up to 50 chats, Plus up to 200, Pro up to 600, Unlimited full migration. Pro and Unlimited also include continuity (style and topic summary). On Unlimited, you can click "Import as chats" to create one Get4oBack chat per conversation and keep your full history in the app. To support large imports and background processing, uploaded .zip or .json files are retained for up to 48 hours so the server can finish processing and you can retry without re-uploading everything. All temporary files are automatically deleted after 48 hours and are never downloaded, manually accessed, or shared.
We're an independent team providing simple access to GPT-4o. Not affiliated with OpenAI.
We use the GPT-4o API - OpenAI's developer API for the GPT-4o model. It's not the same as ChatGPT-4o (the version you used inside ChatGPT), which is no longer available. But they're from the same family, same OpenAI foundation, and the GPT-4o API is the closest thing that still exists. We've carefully tuned the experience to feel as close as possible to the ChatGPT-4o you remember.
OpenAI makes GPT-4o available to developers through their API. We use that access to give regular users a familiar interface for 4o, now that it's been removed from ChatGPT.
Not entirely. On February 17, 2026, OpenAI removed some GPT-4 and ChatGPT-4o APIs, including some mini variants. But not all of them - we use APIs that are still available and working. If they ever remove those too, we've already built Our-4o, a model based on newer GPT versions that replicates the original 4o behavior as closely as possible. You can choose it directly from the app, and if the original ever goes down, we'll notify you immediately. Our-4o will always work - we guarantee it.
Our-4o is a model we built specifically for Get4oBack. It runs on newer GPT versions but is carefully configured to feel like the original GPT-4o - same tone, same rhythm, same conversational balance. Think of it as our insurance policy: if OpenAI ever pulls the plug on the 4o API entirely, you still get the experience you came here for.
We connect to OpenAI's GPT-4o API - the same model family as the ChatGPT-4o you used to have, but accessed through OpenAI's developer platform. We wrap it in a familiar interface and tune the experience to feel like the original ChatGPT-4o as closely as possible.
We plan to keep Get4oBack running for as long as people want the product. If OpenAI ever limits or removes the GPT-4o API, you are not left hanging: we built Our-4o so you still get the same kind of experience from newer GPT models, inside the app. We will only wind the service down if we truly have to; if that ever happened, we would give plenty of notice and help you export your data.
Each plan includes a token allowance per month. On the free plan you get 30,000 tokens per month and your allowance resets every 30 days. On Plus, Pro and Unlimited your allowance resets at the start of each billing period. No surprises.
Yes. Cancel from your account settings anytime. Your subscription remains active until the end of your billing period. See our Terms and Conditions for full details.
Yes. One subscription. Upgrades apply immediately: you pay once the fixed monthly difference between plans (not prorated by day). Downgrades start on your next billing date; until then, nothing changes on your account. Token usage resets on your normal billing date.
You keep a single subscription. If you are signed in, choosing another paid tier opens the app and switches your plan automatically (no second checkout). Use Manage billing for cancel, payment method, and invoices.

Full FAQ page

What about the API? Is it still available?

On February 17, 2026, OpenAI removed some GPT-4o and ChatGPT-4o APIs - but not all. We use the GPT-4o developer API, which is still available. It's not identical to ChatGPT-4o (the version inside ChatGPT), but it's from the same family and is the closest thing that still exists. We've tuned the experience to feel as close to the original as possible.

That said, we know things can change. That's why we've built a backup: Our-4o, a model we created specifically for Get4oBack. It runs on newer GPT versions but is carefully tuned to replicate the original 4o behavior as closely as possible - the tone, the rhythm, the feel.

You can try Our-4o directly from the app whenever you want. And if one day the original GPT-4o API stops working, we'll let you know right away. Either way, Our-4o will always be there - we guarantee its availability.

You'll never be left without access.

If 4o worked for you, it still can.
