ChatGPT

DeepL

Freemium

DeepL translates text, documents and web pages between more than 30 languages, and its output tends to read more naturally than literal machine translation, particularly across European language pairs. You paste text into the browser translator, upload Word, PowerPoint, Excel or PDF files and get a translated file back with the layout intact, or use the desktop, mobile and browser apps. Glossaries fix terminology such as brand names and technical terms, and style rules control formality. Paid plans raise character and file limits, add translation memory, team admin and SSO, and promise that text is not used for model training.

Notion AI

Freemium

Notion AI sits inside a Notion workspace and works on the pages, databases and notes a team already keeps there. You can ask questions about a document, generate a first draft, translate text, fill database properties automatically, and have meetings captured as notes with action items. Notion Agent carries out multi-step tasks such as building a page, editing a database or pulling information from connected apps like Slack and Google Drive. Enterprise Search looks across those same tools. AI usage is metered in monthly credits on Business and Enterprise plans.

AutoGPT

Free trial

AutoGPT began as an open-source autonomous agent project and now ships a hosted platform built around named AI specialists. You pick an expert for content, sales, research or administration, brief it in plain language, and connect the accounts it may use. A coordinating assistant called Otto routes requests to the right specialist and can pull several into one job. Experts run on schedules, and each has its own spending approval threshold. A workflow builder remains available for defining steps by hand, and the whole platform can still be self-hosted with Docker.

Lindy

Freemium

Lindy is a hosted AI assistant that works inside Slack, email and calendar instead of a separate chat window. You describe a task in plain language, connect the accounts it needs, and it carries the work out across roughly 1,500 integrations. Recurring jobs such as a morning brief, a Monday report or post-meeting notes run on a schedule. It records and indexes meetings so teammates can search what was said, drafts replies in your writing style, and keeps a memory folder you can read and edit. Actions with outside effects wait for your approval.

Wordtune

Freemium

Wordtune works at sentence level. Instead of generating whole documents, it offers several rewrite options for the sentence you just wrote, along with switches for formal or casual tone and corrections for grammar, spelling and phrasing. It also continues a stalled paragraph, suggests synonyms and translates text into English across ten languages. Most people use it through the Chrome extension inside Gmail, docs or a CMS, and a web editor covers everything else. The Basic plan is free with limits; Advanced costs $6.99 per month, and a three-day trial covers the paid tiers.

QuillBot

Freemium

QuillBot is a set of editing tools gathered around a paraphraser. You paste text and get rewritten versions in more than ten modes, including academic, formal and simple, or define a custom mode for a house style. Grammar checking, an AI detector, an AI humanizer, a plagiarism checker, a summarizer and a citation generator sit in the same account, which makes it useful for students assembling essays and for editors polishing client copy. The free tier caps paraphrasing at 100 words and two modes; Premium at $8.33 per month on annual billing lifts those limits and adds full detector and humanizer access.
