AI Chatbot & Writer
iPhone app that puts Claude, ChatGPT, Gemini, and Grok behind one chat window with voice and file input.
KnowIt earns its spot on an iPhone home screen by collapsing four model subscriptions into one free download. What you get is access to the models, not the vendors' full products — no web or desktop client, and none of the surrounding tooling an official app ships. Buy Pro only if you hit the free tier's limits often enough that a single Pro subscription beats paying two of the four vendors directly. If you need Google Drive, Slack, or a desktop workspace, look at those native apps instead.

Skip KnowIt if you work from a laptop browser or need your teammates in the same thread — it is an iPhone-only app with no web, desktop, or Android client and no shared workspaces.
The free tier caps queries per day, so the real cost of regular use is the $9.99/mo Pro plan rather than $0.
At $9.99/mo or $59.99/yr, KnowIt sits below the cost of subscribing to two of the four model vendors it routes between, which is where its value case lives. For a solo iPhone user who would otherwise pay for one official app, the free tier covers light use; for heavy daily prompting, Pro undercuts multi-vendor stacks but not a single $20/mo vendor plan with desktop and web access included.

About AI Chatbot & Writer
KnowIt AI Chatbot & Writer is an iPhone app that gathers four major language models — Claude, ChatGPT, Gemini, and Grok — into a single chat interface. Instead of installing four separate vendor apps and paying four subscriptions, you open KnowIt, type or dictate a prompt, and let the app route the task to a model. The vendor describes it as a smart AI chatbot writing assistant powered by those four models, free to download on iPhone. The writing-assistant angle is the practical hook: grammar and style editing, summarization of long documents, and in-chat translation, all without leaving the conversation. Custom instructions let you pin a persona, and searchable history lets you retrieve earlier drafts. Input is not text-only — the app accepts typed prompts, voice input, and file uploads (PDF, images, text), and reads images so you can photograph a page and ask questions about it. An offline mode covers basic queries when you have no signal. The trade-off is scope: this is a mobile-first aggregator, not a replacement for the vendors' own desktop and web clients, and it is iPhone-only. If your work lives on a phone, the convenience and single bill are the point; if it lives on a laptop, it is not.
Behind the Verdict
KnowIt's pitch is consolidation: one iPhone app, four model families (Claude, ChatGPT, Gemini, Grok), one place to type. The vendor's own line — 'your new smart AI chatbot writing assistant powered by Claude, ChatGPT, Gemini and Grok' — describes a router rather than a model. That framing is honest, and it is the right way to read the product. What you get is the models' raw conversational ability plus a writing-assistant layer: grammar and style editing, summarization of long documents, in-chat translation, and custom-instruction personas you can pin so the assistant stops drifting off-voice. Searchable history means a half-decent draft from three weeks ago is still recoverable. Input flexibility is stronger than most mobile chat apps: typed prompts, voice dictation, and uploads of PDFs, images, and text, with image understanding so a photographed page becomes queryable. Where KnowIt does not compete is scope. It is an iPhone app, full stop — no Android, no web client, no desktop app. There are no shared workspaces or collaboration features documented, and no integrations with the tools your team already runs in. Offline mode exists but is explicitly limited. The realistic user is a solo operator on a phone: a student polishing an essay on a commute, a professional drafting an email from a phone, a writer comparing how two models phrase the same paragraph before committing to one vendor. The realistic non-user is anyone whose work lives in a browser, anyone who needs teammates in the same thread, and anyone on Android. Treat KnowIt as a convenience layer over models you could otherwise pay for separately, and it holds up; treat it as an infrastructure replacement and it does not.

Real-world workflow fit
Concrete scenarios for the personas AI Chatbot & Writer actually fits — and what changes day-one when you adopt it.
Photograph a page of a textbook, upload it to KnowIt, ask for a summary and a set of study questions, then dictate follow-up questions by voice while walking.
Outcome: A condensed set of notes and practice questions produced without opening a laptop or switching between model apps.
Paste an intro paragraph, ask Claude and then Grok to rewrite it, use the grammar and style editing pass to tighten phrasing, and save both versions in searchable history.
Outcome: Two comparable drafts to choose from, kept in history so the earlier version is recoverable later.
Upload a PDF business letter, ask for a translation and a grammar check, then use custom instructions to pin a formal tone before sending.
Outcome: A polished, correctly toned letter without leaving the chat or installing a separate translation app.

Where the pricing makes sense
The company stage and team size where AI Chatbot & Writer's pricing actually pencils out — and where peers do it cheaper.
At $9.99/mo or $59.99/yr, KnowIt sits below the cost of subscribing to two of the four model vendors it routes between, which is where its value case lives. For a solo iPhone user who would otherwise pay for one official app, the free tier covers light use; for heavy daily prompting, Pro undercuts multi-vendor stacks but not a single $20/mo vendor plan with desktop and web access included.
Setup time & first value
How long it actually takes to get something useful out of AI Chatbot & Writer — broken out by persona, not the marketing-page minute.
Download from the App Store and you are prompting within a couple of minutes — there is no workspace to configure. Pinning a persona via custom instructions takes another minute or two, and uploading a first PDF or photo is immediate. Realistically under 10 minutes to first useful output for a solo iPhone user.
Switching to or from AI Chatbot & Writer
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From the official ChatGPT, Claude, or Gemini iPhone apps: install KnowIt alongside them, move your recurring prompts into searchable history, and cancel the vendor subscriptions you no longer need.
- ↗To a single vendor's native app (ChatGPT, Claude, or Gemini): subscribe directly to that vendor if you find you consistently route to one model and want its web and desktop clients.
