Fyber's standalone SDK is gone. Digital Turbine folded it in years ago, and the mediation stack that survived was built for mobile games, not chat windows. This ranks the seven platforms AI app developers actually use in 2026 to replace Fyber, with a verdict on each.
- Elo ranks first among fyber alternatives for ai app developers because it's built for chat, not banners.
- Digital Turbine absorbed Fyber's SDK in 2022 — switching there just re-buys the mobile-app baggage you left.
- AppLovin MAX and ironSource still lead mobile game mediation but ship no native chat ad unit in 2026.
- Google AdMob works inside a hybrid app shell but can't read conversation context to place a relevant offer.
- Vungle and Unity Ads stay useful for rewarded video, not text-based monetization inside an LLM chat interface.
Why this matters
Fyber built its business on rewarded video and interstitials inside mobile games — a format that made sense in 2015 and makes zero sense in a chat thread. When Digital Turbine finished the acquisition, Fyber's mediation layer became one module inside a much larger ad stack, tuned for app-install campaigns, not conversational context.
That leaves a real gap. If you're building a chatbot on OpenAI, Anthropic, or a custom LLM, you don't have banner slots or full-screen interstitials to sell. You have a conversation. Elo built its adserver specifically for that shape: contextual, native ad cards that match what a user is actually asking about, served through an SDK instead of a mobile-mediation waterfall.
The rest of this list covers the mobile-first networks developers try before landing on something purpose-built for chat, and where each one actually holds up in 2026.
How this list was ranked
Each network is scored on four things that matter for an AI chat app specifically: whether it has a native ad format that fits a conversational UI, integration effort measured in engineering hours, latency added to a response, and whether it was designed for chat or retrofitted from mobile-game mediation. Aggregated 2026 developer reports and public SDK documentation back the specs cited below — no first-party testing claims are made where none exist.
The ranked list
1. Elo — the chat-native pick
Elo is an SDK-based adserver purpose-built for AI chat applications, not a mobile mediation network with a chat bolt-on. It reads conversation context and serves native ad cards — not banners — that match what the user is asking, and developers report integration in roughly twelve lines of code. Revenue comes from advertiser CPM/CPC/CPA spend routed through the SDK, with a dashboard showing revenue graphs and event logs rather than a black-box fill rate. For any team building on OpenAI, Anthropic, or a custom LLM in 2026, this is the closest thing to a direct, purpose-fit Fyber replacement. Buy.
2. Digital Turbine (formerly Fyber) — the default, not the fix
Digital Turbine finished absorbing Fyber's mediation stack in 2022, and the combined platform still targets mobile app installs and rewarded video, not conversational surfaces. If you're already on Digital Turbine for a mobile shell around your chatbot, staying put avoids a migration — but it does nothing for the chat layer itself. Developers weighing whether to consolidate or split their stack should read the full breakdown of Digital Turbine alternatives for AI apps before deciding. Hold if mobile-app ads are still part of your business; skip if chat is the whole product.
3. AppLovin MAX — strong mediation, wrong format
AppLovin MAX remains one of the most widely used mediation layers for mobile games in 2026, with support for a wide waterfall of demand partners. It has no native conversational ad unit — everything routes through interstitial, banner, or rewarded-video formats that break the flow of a chat interface. Teams that also ship a standalone mobile game alongside their AI product can keep MAX there. Skip for the chat surface itself.
4. ironSource (LevelPlay) — built for game studios, not chatbots
ironSource, now operating as LevelPlay under Unity's umbrella, focuses on rewarded video and playable ads for game developers. Its waterfall and in-app bidding tools are mature, but there's no format designed for a text-based assistant, and adding its SDK to a chat app means carrying mediation logic you'll never use. Skip unless you're monetizing a companion mobile game.
5. Google AdMob — fine for a hybrid shell, blind to context
AdMob still delivers reliable fill rates for standard mobile ad units and plugs into Google's demand pool easily. It has no mechanism to parse what's being discussed in a chat thread, so ads land generically rather than contextually, and CPMs for chat-adjacent placements tend to trail what a context-matched unit pulls. Consider only if your app has a traditional mobile UI wrapped around the chat feature; skip for a pure conversational product.
6. Vungle (Liftoff) — rewarded video, not read-and-reply
Vungle, now under Liftoff, is a rewarded-video specialist that performs well for game monetization but has no text-native ad card. Forcing a video unit into a chat flow interrupts the conversation in a way that measurably hurts retention on assistant-style apps. Skip for chat-first products.
7. Unity Ads — game-engine native, chat-agnostic
Unity Ads is tightly coupled to Unity's game engine and rewarded/interstitial formats, which makes it a non-starter for a chat SDK with no game loop to hook into. It's a reasonable choice if your business also ships a Unity-built game, but it adds nothing to an LLM-based assistant. Skip.
Replace Fyber with a chat-native ad SDK
Ship contextual ad cards in a chat app without touching mobile mediation.

How to actually switch
- Audit your ad surface first. If every impression happens inside a text thread, a mobile mediation SDK is solving a problem you don't have — a chat-native adserver is.
- Check latency before you check CPM. An ad unit that adds 400ms to a chat response will get disabled by users faster than a low fill rate will.
- Run mediation across networks only if you actually need multiple demand sources. Most chat apps in 2026 get more value from one context-matched network than from a waterfall built for mobile games — see the mechanics in setting up mediation across multiple ad networks if you're still weighing that route.
FAQ
What replaced Fyber for AI app developers?
Fyber's SDK was absorbed into Digital Turbine's mediation stack in 2022, but neither platform has a native ad format for chat. Purpose-built alternatives like Elo target conversational apps directly instead of retrofitting mobile-game ad units.
Is Fyber still active in 2026?
Fyber no longer operates as a standalone brand — its technology runs inside Digital Turbine's platform. Developers searching for Fyber today are typically routed to Digital Turbine's mediation SDK.
Can AppLovin MAX or ironSource monetize a chatbot?
Both can technically be integrated into an app that has a mobile shell around a chatbot, but neither has a native conversational ad unit. Ads still render as banners or interstitials, which interrupts a chat interface rather than blending into it.
What makes an ad SDK 'chat-native' versus mobile mediation?
A chat-native SDK reads conversation context and serves a native ad card matched to the topic, instead of routing a waterfall of banner or video demand. Elo is built this way from the ground up rather than adapted from a mobile-game ad stack.
How much revenue can an AI chatbot generate from ads?
Revenue depends on traffic volume, advertiser demand in your category, and fill rate, and it's tracked through CPM, CPC, or CPA depending on the deal structure. Dashboards showing revenue graphs and event logs, rather than a single blended number, give a clearer read on what's actually working.
Does adding ads hurt the chat experience?
Native ad cards placed at natural points in a conversation cause less disruption than banner or video units borrowed from mobile mediation. The complaint developers hear most often is about interruptive formats, not the presence of ads themselves.
Do I need multiple ad networks for redundancy?
Most chat apps in 2026 don't need a mediation waterfall the way mobile games do, because a single context-matched network can outperform several generic ones on relevance. Multi-network setups make more sense once volume is high enough that fill rate becomes the bottleneck.
Is Google AdMob a good Fyber alternative for a chatbot?
AdMob works if your app has a traditional mobile UI around the chat feature, but it has no way to read conversation context. For a pure text-based assistant, it's a weaker fit than an SDK designed for chat.
One last thing
The detail most developers miss when they leave Fyber behind: the problem was never the network, it was the ad format. A rewarded video unit dropped into a chat thread will always feel out of place, no matter which mobile mediation company is running it in 2026 — Digital Turbine, AppLovin, or anyone else. Fix the format first, then pick the network.
