Sidekick

Sidekick is an iOS AI assistant that unites multi-model chat, Projects, cited web answers, PDF and YouTube summaries, image, video and voice creation, and 18 AI characters, with guest access and a free daily tier.

Sidekick is an AI assistant built for iOS that combines a multi-model chat interface with research, summarization, creative generation and a camera-based helper. Rather than tying users to a single model, it lets them choose among models from OpenAI, Anthropic, Google and others for each conversation, which makes it a practical way to compare how different systems handle the same task without juggling separate apps. The core organizing idea is Projects. A Project groups chats, files, research notes, model preferences and web settings under one topic, so ongoing work such as a study subject, a job search or a writing piece keeps its context in one place. Around that sit several task modes. Web answers use search or a research mode and return inline citations with source lists. A summarization feature handles web pages, PDFs, Markdown, pasted text and YouTube transcripts when they are available. The camera can scan text, identify objects, solve visual or math problems and answer questions about photos. Writing tools cover drafting, rewriting, translation, brainstorming and polishing email or resumes. On the creative side, Sidekick generates and edits images, turns images or photos into short videos, produces voices, and stores results in a gallery called My Gallery. It also offers 18 AI characters for conversational chat. Access starts without an account: a guest can begin immediately, and signing in with Apple is optional. The free tier provides daily messages on faster models, while a Pro subscription unlocks flagship models, image and video generation and removes daily limits, billed through the Apple ID. On privacy, the developer states that conversations are stored on the device, that nothing reaches AI providers before consent is given in the app, and that user data is not used to train models. Provider requests pass through a server proxy. Sidekick suits individuals who want one iPhone app covering chat, research, document digestion and media creation. Compared with single-vendor apps, its strengths are model choice and project organization; compared with desktop-first tools, it is limited by being iOS only.
