Daily Prompt Duel — ChatGPT vs Claude vs Gemini, Side-by-Side, BYOK — Generated 2026-04-20
The "compare AI models" space splits into three camps: web-only research tools (LMArena, Sider), credit-gated aggregators (Poe, Arcane), and power-user BYOK desktop tools (TypingMind). None of them ship a daily, gamified, TikTok-exportable habit loop on iOS. AIDojo is the first edutainment wedge — Duolingo-shaped habit on top of a side-by-side duel — aimed at the AI-curious 18–34 who already pay for two or more assistants.
Daily prompt challenge. ChatGPT, Claude, and Gemini streamed side-by-side via BYOK. Foundation Models "AI-taste" profile after 30 days. One-tap TikTok share card. $1.99 unlock + $2.99/mo — a fraction of a single competitor subscription.
Multi-model credit aggregator. GPT-5, Claude 4, Gemini 2.5, Llama, DeepSeek, Grok behind Poe's paywall. $5/mo starter (10K points/day), $19.99, $49.99, $99.99, up to $249.99/mo. Quora distribution + bot-builder creator program. No BYOK, no daily challenge.
Power-user BYOK frontend. Standard $39, Extended $79, Premium $198 (often discounted to $99) — all one-time. Multi-model chat, custom agents, plugins, SOC 2. Mobile companion launched late 2025. Indie-hacker Twitter and YouTube prompt-engineering creator distribution.
Industry-reference blind-voting leaderboard. a16z-seeded Jan 2026, cited in every major AI paper. Monetizes via API benchmarking licenses to labs, not consumers. Web-first, no official iOS or Android app. Recent "LMArena AI Mobile" on the App Store is a third-party knockoff, not official.
iOS-native "three chats glued together." $6.99/mo or $39.99/yr, cloud-proxied ChatGPT + Claude + Gemini (no BYOK). Acquisition via TikTok "ChatGPT vs Claude" demo videos and Apple Search Ads on "compare AI". First-mover on iOS split-screen compare.
Sider is a Chrome/Edge sidebar that pits GPT-5, Claude, Gemini, Llama, Grok in a single "AI Group Chat" view — browser-only, not iOS. Duolingo Max ($29.99/mo or $168/yr, often $14/mo annual) owns the daily-habit AI layer — but locked to language pedagogy. Khanmigo at $4/mo owns classroom.
AIDojo is the only product combining BYOK side-by-side compare, a daily curated prompt, an on-device AI-taste classifier, and a portrait TikTok share card — as a native iOS habit at a sub-$3/mo price. Poe and Arcane have parallel models but no learning loop. TypingMind has BYOK but no daily hook. LMArena has voting but no app.

Scenario: an AI-curious user who already pays for ChatGPT Plus ($20/mo) and wants to compare across Claude and Gemini too. AIDojo at $1.99 unlock + $2.99/mo taste tier beats every competitor on both cost AND functionality. Note the stacked alt row: users currently pay $720+/yr for ChatGPT Plus + Claude Pro + Gemini Advanced + Poe + Arcane just to answer "which AI is better for me?"
| App / Stack | Year 1 | Year 2 | Year 3 | 3-Year Total | What You Actually Get |
|---|---|---|---|---|---|
| AIDojo (unlock + taste sub) | $37.87 | $35.88 | $35.88 | $109.63 | $1.99 lifetime unlock + $2.99/mo taste tier. BYOK (you pay API providers directly, ~$3–10/mo). Daily duel, AI-taste profile, TikTok export. |
| AIDojo (unlock only, no sub) | $1.99 | $0 | $0 | $1.99 | Lifetime 3-model compare + unlimited history + unwatermarked exports. No personality profile. Pure BYOK. |
| Poe (standard $19.99/mo) | $239.88 | $239.88 | $239.88 | $719.64 | 1M points/mo — can exhaust in days on long chats. Sequential, not side-by-side. No daily challenge. |
| Poe ($5/mo starter) | $60.00 | $60.00 | $60.00 | $180.00 | 10K points/day. Still no compare view, no habit loop, no BYOK. Points depreciate as chat grows. |
| TypingMind Premium | $99.00 | $0 | $0 | $99.00 | One-time Premium (discounted). BYOK. Desktop/web-first. No daily prompt, no gamification, no TikTok. |
| LMArena | $0 | $0 | $0 | $0 | Free, web-only. Blind global vote. No personalization, no iOS app, no habit loop, no export. |
| Arcane annual | $39.99 | $39.99 | $39.99 | $119.97 | Three cloud-proxied chats side by side. No BYOK, no AI-taste, no daily challenge. Users churn at week 2. |
| Sider Pro | $148.80 | $148.80 | $148.80 | $446.40 | Browser extension only — no iOS habit. Credit-metered. AI Group Chat works but sits in Chrome/Edge. |
| Duolingo Max (annual) | $168.00 | $168.00 | $168.00 | $504.00 | AI Roleplay + Video Call — language-learning only. Can't evaluate ChatGPT vs Claude. |
| Stacked alt (ChatGPT+ + Claude Pro + Gemini Adv + Poe $19.99) | $959.88 | $959.88 | $959.88 | $2,879.64 | What a serious AI-curious user pays today. Three $20/mo subscriptions + Poe aggregator. Still no side-by-side compare on mobile. |
* AIDojo's $1.99 unlock is a rounding error against a single month of ChatGPT Plus. The thesis isn't "replace your ChatGPT Plus subscription" — it's "give users a way to decide whether their Claude Pro or Gemini Advanced subscriptions are worth keeping." Users save $20–$40/mo by cancelling the models AIDojo shows them they don't actually prefer. That's a 10x payoff on a $1.99 install.

Sider: $4.20–$16.70/mo, Chrome/Edge extension with AI Group Chat. Duolingo Max: $29.99/mo or $168/yr, AI Roleplay + Video Call, language-locked. Khanmigo: $4/mo learner, $9/mo family, 100% free for teachers — but subject-locked.
Five structural advantages that compound into a defensible position. Poe can't pivot off credits without tanking $100M+ ARR. TypingMind can't gamify without losing power-user trust. LMArena won't ship an iOS habit. Arcane can't add BYOK without killing proxy margin. None of them can copy all five moves at once.
One BYOK setup, two apps. Shared keychain group group.com.dreamseeds.ai means AIDojo and AskRouter both read the same user-owned keys. Poe can't do this (no BYOK). Arcane can't (cloud proxy). TypingMind can't (no second consumer app).
Apple Foundation Models classify 30 days of user votes into a personality profile ("you prefer Claude for writing, ChatGPT for code"). No cloud, no backend, no leak. LMArena produces global opinions; AIDojo produces yours. This is the only thing in the category that answers "which AI fits me?"
Duolingo proved "60-second daily streak" beats every pro-grade product on retention. AIDojo is the first to apply that shape to AI literacy. Poe, TypingMind, Arcane are all task-driven; none push, none streak, none recap. Adding a streak at Poe's scale would tank chat minutes, so they won't.
ImageRenderer to 1080×1920 with prompt, 3 answers, user's vote, and taste stat. "Day 12 of asking every AI 'what's my personality?'" cards are inherently shareable. Arcane has no export, Poe can't watermark its own brand in, LMArena has no user history. AIDojo's acquisition cost drops every week the share cards spread.
A 120x price gap against Poe Standard ($19.99/mo) and a 10x gap against Arcane ($6.99/mo). "Break even with one cancelled Claude Pro" is a genuine message. Poe can't match without blowing $100M+ ARR. Arcane can't without bleeding proxy margins. AIDojo's willingness to stay free-to-try keeps the floor.
AIDojo
iOS daily habit • BYOK • 3-model parallel • On-device AI-taste • 1080×1920 TikTok export • $1.99 lifetime + $2.99/mo
Shape: Duolingo-for-AI
Price: $1.99 + $2.99/mo
Closest Competitor (Arcane)
iOS-native • Cloud-proxied • 3-model • No daily challenge • No taste profile • No export • 2-week churn
Shape: Novelty compare
Price: $6.99/mo recurring
Leads with the personal-discovery frame (not "compare AI models" which every competitor already owns). The word "duel" borrows the word everyone is already saying. "Fits you" signals personalization — the exact gap LMArena and Arcane leave open.
Targets Poe's #1 Reddit complaint: credit roulette. BYOK + one-time unlock are both structurally cheaper. "Rent to the middleman" is a Poe user's own language re-weaponized. Easy TikTok hook: "I cancelled Poe's $19.99/mo, here's what I use instead."
Concedes TypingMind's power-user supremacy (don't attack their base) and positions AIDojo as the top-of-funnel discovery step. "Use AIDojo to find your model, then graduate to TypingMind" is a co-existence story that doesn't threaten their ICP.
Respectful of LMArena's authority (don't attack an a16z-seeded research brand), then flips the scope: global vs. personal. "They rank for everyone. We rank for you." Invites LMArena citation in-app as social proof without competing for the same user session.
Targets Arcane's 2-week churn directly: three chat windows is cool for a week, then what? AIDojo is the daily habit on top of the compare view. "Compare is table stakes. The learning loop is the product." $1.99 undercuts $6.99/mo on install.
25/30 chars. Subtitle: "Daily prompt duel • BYOK" (25/30). Primary: Education (secondary: Productivity). ASO keyword whitespace: "prompt duel", "AI taste test", "AI literacy daily", "BYOK AI chat" — all uncontested.
