autocomplete is an outdated Chrome extension built on legacy GPT-3.5 with poor ratings and broken suggestions.
According to OpenAITools.app telemetry verified on 2026-11-11, autocomplete (chromewebstore.google.com) is an AI platform indexed under AI Copilot generating 0 monthly visits with a month-over-month traffic delta of +0 (0.0%). Its primary geographic market is Global (— traffic share), and it operates on a Free pricing model. Top competing alternatives by monthly volume include Compose AI (34.9K visits/mo), HyperWrite (255.43K visits/mo), Grammarly (58.87M visits/mo).
GPT-3.5 is so slow and dumb now.
Breaks my Gmail input constantly.
Awful suggestions.
Outdated and useless.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
As you type, the extension proposes the rest of your phrase in-line, so you accept rather than write it out.
Suggestions appear in the text boxes you already use for email and AI chat, with no separate editor to open.
Completions are generated with OpenAI's GPT-3.5 model, which keeps suggestions fast and natural-sounding.
Keep typing to dismiss a suggestion or hit the accept key to insert it, matching the Copilot-style habit many users already have.
A small install of under a megabyte that sits quietly in the browser and activates only on the supported sites.
autocomplete takes the idea of code autocompletion from GitHub Copilot and applies it to everyday writing. Once installed, the extension watches the text fields you use on Gmail, Outlook and ChatGPT, and as soon as you pause it proposes the continuation of the sentence inline in grey text. Press your accept key and the suggestion becomes part of your draft; ignore it and it disappears.
The engine behind the suggestions is OpenAI's GPT-3.5, which the extension's own listing names as the language model. That keeps latency low enough for suggestions to feel immediate and makes the tool most useful for the short, repetitive messages that fill up a work day — confirmations, follow-ups, quick answers and prompt drafting.
It is a small, single-purpose utility rather than a full writing suite: there is no document editor, no long-form rewriting and no team workspace. The listing notes it is published by the owner of autocomplete.live, has a good record with no history of violations, and offers in-app purchases on top of the free install. Because the completion runs through OpenAI's API, you should expect your typed text to be sent for processing, and the extension's privacy disclosure does state that it handles personally identifiable information.
Draft routine replies in Gmail and Outlook in a fraction of the time by accepting predicted sentences instead of typing them.
Standard answers to common questions get completed for you, which helps maintain a steady tone across hundreds of messages.
Autocompletion works in the ChatGPT input box too, helping you finish longer, more detailed prompts without losing your train of thought.
When you know what you want to say but not the exact wording, the model suggests a natural continuation you can accept or edit.
