ChatGPT Writer

Devcraft Studio · ライティング

ChatGPT Writer is an AI writing assistant that runs as a browser extension and drafts emails, messages, and replies inside the sites where you already type. Think of it as an AI email writer that lives in your inbox. It's now branded Jetwriter AI, after a September 2025 rebrand, but the product underneath is the same tool that put ChatGPT into Gmail back in 2022. It works on Gmail, LinkedIn, Outlook, Slack, and most editable text boxes, and it's powered by a mix of GPT-5, Claude, and Gemini models rather than a single AI.

ChatDOC

PAI Tech · 生産性向上

ChatDOC is an AI PDF chat assistant built by PAI Tech that lets you chat with PDF files instead of skimming them. You ask a question in plain language and get the answer back with citations. Upload a PDF, Word file, scanned page or website URL, and it summarizes, extracts and explains the content, then cites the page and snippet behind every answer. It runs in a browser plus Chrome and Edge extensions. A free plan covers light use before the Pro subscription takes over.

Chatbase

Chatbase Inc. · マーケティング · チャットボット

Chatbase is a no-code chatbot builder for AI customer support. It's an AI chatbot platform that trains agents on your own documents, website, and tickets. You add your content, pick a model, and deploy the agent across a website widget, email, WhatsApp, Slack, Messenger, Instagram, or inbound phone calls. It started as a way for small teams to answer repetitive questions, and it now sells an enterprise tier with SSO, SLAs, and HIPAA support.

Character AI: Chat, Talk, Text

Character Technologies, Inc. · チャットボット

Character AI is a chatbot platform where you talk to AI characters instead of a single assistant. You can pick from millions of community-made personas, build your own with a written personality and greeting, or use characters built by the Character AI team. It's the easiest way to chat with AI characters that have a consistent voice. It runs in a browser and as an iPhone and Android app, and the Character AI free plan keeps messaging unlimited.

Captions

Mirage · ライティング · 動画

Captions is an AI video editor and generator built by Mirage, a New York company that also builds the Mirage foundation models behind the app. You upload footage or a prompt, and Captions cuts scenes, adds B-roll, music and styled captions, or generates new talking-head video with an AI Twin. It runs on iOS, Android and the web, and most of its advanced AI work sits behind a paid plan.

Caktus AI

Caktus AI · ライティング · コーディング

Caktus AI is an AI study tool and academic writing platform built for high school and college students. It bundles more than 25 specialized tools into one subscription, including an AI essay writer with verifiable citations, a step-by-step math solver, an AI humanizer, a citation finder, flashcard maker, and STEM assistants. Instead of juggling separate apps for research, writing, and exam prep, students get one dashboard that covers most of what a single semester throws at them.

Browse AI

Browse AI · コーディング

Browse AI is a no-code web scraper and website monitoring platform that turns almost any web page into a structured dataset or a callable API. You train an AI agent, called a robot, by clicking through the elements you want, and it repeats that task on a schedule. It suits teams that need product prices, listings, or competitor pages tracked without maintaining scraping scripts.

Boomy

Boomy Corporation · 音声・言語

Boomy is a browser-based AI music generator that turns style presets into finished instrumental tracks you can edit, save, and download. It works as an AI song maker for people who want usable background music for videos without learning a DAW or music theory, and its paid tiers hand over full commercial rights on anything you download. You don't need a prompt, and you don't get AI-sung lyrics from text.

BlueWillow

BlueWillow (owned by LimeWire) · 画像

BlueWillow is a free AI image generator that turns a short text prompt into logos, graphics, character art, and photo-realistic scenes. It started life as a Discord bot. Now it also runs in the browser through LimeWire AI Studio, which acquired it in 2023. You type what you want, wait a few seconds, and get back a set of variations you can refine or upscale. There's no subscription needed to start, which is why it stayed popular as a low-cost entry point into AI art generation.

BlackInk

BlackInk AI · 画像

BlackInk is an AI tattoo generator that turns a written idea into a custom tattoo design in seconds, then lets you refine the style, complexity, and body placement before you take it to an artist. It's built for tattoo planning rather than general image creation, with tools for stencil conversion, cover-up concepts, and filler pieces. A free tier gives you a few credits to try it, and a Pro Unlimited subscription removes the generation cap.

Beatoven.ai

Beatoven Private Limited · 音声・言語

Beatoven.ai is an AI music generator that turns a short description into royalty-free background music for videos, podcasts, games, and other media. You type what you want, or drop in a reference audio clip or video, and its homegrown Maestro model produces AI generated music you can then reshape by mood, genre, tempo, and instruments. Every download ships with a license, which is the part most creators actually care about.

AutoDraw

Google Creative Lab · 画像

AutoDraw is a free web-based drawing tool from Google Creative Lab that pairs machine learning with artwork from professional illustrators. You sketch a rough shape with a mouse or finger, and the tool suggests finished clip art you can drop onto the canvas in one click. It runs in a browser on phones, tablets, and computers, needs no download or account, and costs nothing to use. Think of it as a drawing app that handles the hard part for you, as long as what you're drawing is something it already knows.
