10 Best AI Chatbot Apps for iPhone of 2026

ChatGPT is the default choice for a reason: the free iPhone app already bundles Advanced Voice Mode, image generation, photo upload and synced history, so most people can stay on the free tier for a while. OpenAI's App Store listing describes the voice feature as a real-time conversation started from the soundwave icon, which makes it useful for language practice or quick questions while walking. Paid plans are sold as in-app purchases: ChatGPT Go at $8.00 and ChatGPT Plus at $19.99, with Pro options at $100.00 and $200.00 for heavy users. The app also carries 12M US ratings at an average of 4.8, the largest base in this list. What the listing does not do is explain the model or usage limits per tier, so check OpenAI's plan page before upgrading. It also does not list connected apps the way Gemini and Claude do, which matters if you want your email and calendar inside the chat.

Gemini is the strongest value pick for iPhone owners who already use Google services. The free app includes Gemini Live, which lets you talk in real time and share your camera or screen so the assistant can discuss what you see, plus image generation with Nano Banana 2 and file uploads for summaries. Connecting Gmail, Calendar, Google Photos, YouTube and Search gives answers based on your own data, and the Daily Brief agent assembles a morning summary. Paid tiers are sold in the app and bundle cloud storage: Google AI Plus with 400 GB at $4.99, Google AI Pro with 5 TB at $19.99 and Google AI Ultra with 30 TB at $199.99. Video generation with Gemini Omni starts at Plus. The main limit is the platform itself: Google's listing says Gemini does not currently support iOS device actions such as setting alarms or sending SMS, so it will not replace Siri for phone control.

Claude is the pick for people who use an assistant to think, write and work through documents rather than to make pictures. The iPhone app handles voice conversations in multiple languages, web search with citations, and uploads of photos, PDFs and screenshots, where Claude reads text, charts and diagrams. You can connect Google Drive, Gmail and Calendar to bring your own context into a chat, and Anthropic's listing says the app runs the Fable, Opus, Sonnet and Haiku models. Pro costs $20.00 per month or $214.99 per year as an in-app purchase. Higher tiers cost more through Apple than on the web: Max is $124.99 and Ultra $249.99 per month in the app, against $100 and $200 on Anthropic's own pricing page, so buy those on the web if you can. There is no image generator listed, which keeps it behind ChatGPT and Gemini for creative work.

Perplexity works more like a search engine that writes than a chatbot, and that is its strength on a phone. Every answer comes with cited sources, follow-up questions keep the thread going, and Pro Search and Deep Research handle longer investigations. Perplexity says the app uses top models from OpenAI, Anthropic, Meta and others, so you get several model families behind one subscription. Newer additions include an Assistant that drafts emails, schedules appointments and books reservations, and Labs for building reports. Voice is offered for asking questions out loud and getting current answers. Pro is $20.00 per month in the app, with a $200.00 option and Perplexity Max at $200.00 for heavy users. It scores below the top three because it is less suited to casual conversation and creative tasks, and because its paid tier costs more than the entry tiers from Google and OpenAI.

Copilot is the work-first assistant in this list. Microsoft's iPhone app connects to Word, Excel, PowerPoint, Outlook and Teams, so it can summarize a file, draft an email or build a presentation from what you already have. Cowork takes on multi-step jobs and returns finished files, and the app lets you choose between leading AI models for each task. Uploads cover Office files, images and PDFs, and memory carries context between sessions. Subscriptions are Microsoft 365 plans sold in the app: Personal at $9.99, Family at $12.99 and Premium at $19.99 per month, which also bring the Office apps and cloud storage. That bundle is good value for existing Microsoft users and weaker for everyone else. The App Store listing does not describe a voice mode, and Microsoft notes that feature availability varies by license, so check what your plan includes.

Grok is the choice for people who want real-time answers drawn from X alongside the web. The iPhone app pairs chat and deep research with Grok Imagine, which makes images from text or voice, short videos with sound, and videos from your photos, with editing tools for backgrounds and objects. Voice Mode gives real-time spoken replies and lets you choose conversation styles. A transfer tool brings chats and context over from ChatGPT, Claude or Gemini, which lowers the cost of trying it. In-app pricing starts with SuperGrok Lite at $10.00, then SuperGrok at $30.00, SuperGrok Plus at $100.00 and SuperGrok Heavy at $300.00. Its App Store rating is the highest in this list at 4.9 from 1.6M US ratings. It ranks seventh because the useful tiers cost more than Gemini or ChatGPT Go, and because answers that lean on X suit news more than reference questions.

Meta AI is the best free option for people already inside Meta's apps. The iPhone app, built on Meta's Muse Spark model, handles voice or text chat, with voice support for 13 languages and live AI that answers questions about what you see. It creates and edits images, writes research reports, reads uploaded documents and spreadsheets, and offers Incognito Chat for temporary conversations. It is also the required companion app for Meta's AI glasses. Connections cover Instagram professional accounts, Meta Ads Manager and Google Workspace. The App Store page lists the app as free with in-app purchases but shows no subscription prices, so there is nothing to compare against ChatGPT Go or Google AI Plus. The trade-off is data: Meta says the assistant taps into what people share across Instagram, Facebook and Threads and picks up on creators and brands you follow, and some features are limited by country and language.

Vibe is the new name for Le Chat, Mistral's assistant, and the iPhone app now leans toward agent-style work. Mistral describes runs that catch you up across email, chat, calendar and internal knowledge, deep research across the web and connected tools with sourced analysis, spreadsheet analysis, and drafting of reports and updates. The free tier is pitched at quick answers and everyday tasks, and Pro at complex work and deeper reasoning. Pro costs $14.99 per month or $149.99 per year in the app, which undercuts the $19.99 to $20.00 tiers from OpenAI, Google, Anthropic and Perplexity. The listing is thinner than its rivals: it does not describe a voice mode or image tools, and the app has only 1.4K US ratings. Pick it if you want a European vendor or a cheaper Pro tier for text work.

DeepSeek is the free-only pick. The official iPhone app gives free access to DeepSeek's latest flagship model, and the App Store page lists no in-app purchases at all, so there is no tier to upgrade to and no limit you can pay to raise. It is a small 78 MB download with support for English and 71 more languages. That simplicity is also its weakness: DeepSeek's listing describes no voice mode, no image generation and no app connections, so it competes only on text chat. It also has the lowest US rating in this list, 3.9 from 13K ratings. The developer is Hangzhou DeepSeek Artificial Intelligence, which some users will consider when deciding what to type into it. For a free text assistant it works, but the free tiers of ChatGPT, Gemini and Meta AI include voice and images that DeepSeek does not document.

Poe is a hub rather than a single assistant. Quora's app gathers models from OpenAI, Anthropic and Google along with image and video generators such as FLUX, Ideogram, Stable Diffusion, Veo and Runway, and it lets you put several bots into one chat thread to compare their answers. More than 1 million custom bots cover tutoring, file chat and characters, and you can build and share your own in minutes. Pricing is friendly at the bottom: Basic is $4.99 per month or $49.99 per year in the app, matching Google AI Plus as the cheapest paid tier here, while Plus costs $19.99 per month or $199.99 per year. The App Store text has not kept pace and still names models such as GPT-4.5 and Claude 3.7 Sonnet, so check the model list inside the app. No voice mode is described, which leaves it behind the single-lab apps for spoken use.
