## Fello AI (HelloAI)

Fello AI is the current identity of the app originally shipped as HelloAI - AI Chatbot Assistant. Still published by AI Apps Brewery s.r.o. under the same App Store ID, it has evolved into a multi-model AI workspace for Apple devices: rather than subscribing to ChatGPT, Claude and Gemini separately, you get access to a broad set of leading text and image models inside one fast native app on Mac, iPhone and iPad.

The everyday workflow is broad. You can ask questions by voice or text, upload PDFs, images, spreadsheets, presentations, iWork documents, code and logs to summarise or transform them, let the app search the web automatically when a model needs current information, or trigger Deep Research for more involved questions. Image generation and editing are built in, and Skills package common jobs such as planning a trip, producing a podcast script or drafting written content.

What sets it apart from a plain chat client is output: Fello AI creates real .pptx, .xlsx, .docx and .pdf files directly from the conversation, complete with charts and formulas, and organizes parallel workstreams into Projects so chats and files stay together. With a 4.6-star average across roughly 140 App Store ratings, it is a well-received productivity tool; some users have asked for better chat syncing between devices, which the developer has been addressing.

**Pricing & Plans:** Free to download with a limited daily message allowance on the free tier. Unlimited access to all AI models and Skills requires an in-app subscription, which includes a free trial; no ads or hidden fees.

- **Many leading models in one app:** Switch between current GPT, Claude, Gemini, Grok, DeepSeek, Qwen, MiniMax, Kimi and other models for text and image tasks without juggling separate subscriptions.
- **Real document generation:** Create genuine .pptx, .xlsx, .docx and .pdf files — pitch decks with charts, spreadsheets with working formulas, reports and more — directly from chat.
- **Chat with your files and use voice:** Upload PDFs, images, spreadsheets, presentations, iWork files, code or logs to summarise, analyse and transform them, or simply talk to the assistant.
- **Web search and Deep Research:** The app can search automatically when a model needs fresh information, and Deep Research digs into complex topics systematically.
- **Projects, Skills and multi-device sync:** Keep related chats and files in Projects, use Skills for travel, podcasting and writing, and sync work across Mac, iPhone and iPad.

**Strengths:** One subscription covers many leading AI models for text and images; Generates genuine Office and PDF files with charts and formulas; Native Mac, iPhone and iPad experience with voice input; Handles file questions, web search and Deep Research in the same workspace

**Limitations:** Full model access requires a paid subscription; the free tier caps daily messages; Some users report that chat syncing between devices has been inconsistent; Aggregating many models means you depend on the developer's own model routing and pricing

## Perplexity

Perplexity is an AI-native answer engine and autonomous research platform designed to replace traditional keyword search and fragmented browser tab workflows. Instead of returning a ranked list of blue links, Perplexity interprets complex natural-language queries, crawls live web indexes, academic databases, financial filings, and social discussions in real time, and synthesizes direct, structured answers anchored by numbered inline citations. Beyond conversational search, the platform has evolved into a broader agentic ecosystem encompassing Perplexity Computer for autonomous multi-step tasks and the Comet AI browser assistant.

Under the hood, Perplexity orchestrates its proprietary web-grounded Sonar model family alongside frontier third-party reasoning models—allowing paid subscribers to route queries through Claude Opus 4 and Sonnet 4, OpenAI's o3-pro and GPT series, or Google's Gemini models, or run parallel evaluations via Model Council. Its Deep Research mode autonomously decomposes intricate questions, conducts dozens of iterative searches across hundreds of primary sources, and compiles exhaustive, exportable briefing reports in minutes. Users can also organize ongoing projects inside Perplexity Spaces, which fuse uploaded private documents (PDFs, CSVs, docs) with live web grounding and custom system instructions.

Perplexity serves an expansive audience ranging from students and journalists to equity analysts, legal researchers, and software engineers. Individual users can rely on the free tier for everyday fact-checking, step up to Perplexity Pro ($20/month) for daily deep research and model switching, or subscribe to Perplexity Max ($200/month) for uncapped high-compute agentic runs. Organizations adopt Enterprise Pro ($40/seat/month) and Enterprise Max ($325/seat/month) for SOC 2 compliance, zero data training guarantees, and internal knowledge connectors, while developers integrate real-time grounded citations into custom software via the Sonar REST API.

**Pricing & Plans:** Offers a permanent Free tier with unlimited Quick Searches, 3 Pro Searches per day, and 1 Deep Research query per month; Perplexity Pro costs $20/month ($200/year) and Perplexity Max costs $200/month ($2,000/year) for individuals. Team plans start at $40/seat/month ($400/seat/year) for Enterprise Pro and $325/seat/month for Enterprise Max, alongside usage-based Sonar API billing.

- **Deep Research Autonomous Reports:** Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
- **Multi-Model Routing & Model Council:** Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
- **Perplexity Spaces & Hybrid RAG:** Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
- **Perplexity Computer & Comet Assistant:** Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
- **Sonar Web-Grounded Developer API:** Exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over standard HTTP endpoints so developers can embed low-latency, live-cited web intelligence directly into third-party applications.

**Strengths:** Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.; Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.; Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.; Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

**Limitations:** The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.; Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.; Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
