OneAnswerAI

Stop guessing which AI gives the right answer. OneAnswerAI sends your question to OpenAI, Google Gemini and Anthropic Claude at the same time and gives you back one answer, built by comparing the three. -- HOW IT WORKS -- Every model has different strengths and different blind spots. Alone, each gets things wrong in its own way; compared, they correct each other. OneAnswerAI does that work for you: no opening three apps and reading three answers. Choose how your answer is built: FUSION MODE The three answers are merged into one that keeps the best of each. The recommended mode when reliability matters. PICKING MODE Want one specific model? You choose which one answers. -- TRY IT FREE -- The free plan includes a few questions a day, answered by Gemini. Your first question gets the full fused answer of all three models, so you see the difference before you decide. -- WITH PRO -- - Answers fused from OpenAI, Gemini and Claude, 40 questions a day - See where the three models agree and where they do not, answer by answer - Ask a specific model for a second opinion on an answer - Attach photos, screenshots, charts and PDFs: the models read them - Photograph a receipt and the app extracts vendor, total, items and VAT - Web search when needed, for up-to-date answers - Create and edit images (account required, adults only) -- ALWAYS INCLUDED -- - Conversations stay saved: search them, rename them, pin them - Set your level and your instructions once, and they apply to every answer - If an answer does not convince you, report it from the chat - 7 languages: English, Italian, Spanish, French, German, Arabic, Chinese -- WHO IT IS FOR -- Students who want to check an assignment or a research paper before handing it in, and professionals who cannot trust the first answer that comes along.

Verdict
The clearest difference is in-app purchases: BigOit at none against OneAnswerAI's 7. BigOit also leads on ads (none vs shown) and update cadence (every 2 days vs every 9 days). OneAnswerAI's advantage is iOS requirement (16.4 vs 26.0). On price and device support there is nothing between them.
