Rather than making you plan every prompt from scratch, it watches what you type and offers inline sentence continuations; hitting Tab accepts the suggestion and drops it straight into the input box. The value is speed and rhythm. Reusing a prompt pattern, writing a long instruction, or drafting a follow-up message inside a chat goes faster when the extension guesses the next few words for you. Because the suggestions consider the sentence you have already started, they tend to stay on topic rather than producing random filler. It is a free, no-frills utility: the Chrome Web Store listing shows version 0.3, updated in August 2024, roughly 291 users and a 2.5-star average from 10 ratings. The developer marks it as beta and notes that some users may need to add their own Hugging Face GPT-2 API key. It is a small side project rather than a polished commercial product, but the listing is live and downloadable. **Pricing & Plans:** Completely free Chrome extension. No subscription or paid tier is listed; if you hit issues in the beta, the developer may ask you to supply your own Hugging Face GPT-2 API key. - **Tab-to-accept completions:** A greyed-out suggestion appears as you type in ChatGPT; press Tab to accept the completion and keep the flow going. - **Context-aware sentence continuation:** Suggestions are built from the sentence you are writing, so continuations match the prompt you actually started rather than generic boilerplate. - **Built for the ChatGPT composer:** Purpose-built for the GPT chat interface, so completions appear right where you compose prompts and replies without a separate window. - **Zero-setup extension:** Installs from the Chrome Web Store in seconds with no configuration, account or onboarding flow. - **No-data-collection declaration:** The developer declares that no user data is collected, sold or used outside the core functionality. **Strengths:** Free with no account or subscription required; Tab-to-accept completions make long prompts much faster to write; Context-aware suggestions stay aligned with the sentence you started; Clear declaration that no user data is collected or sold **Limitations:** Beta version with only a 2.5-star average from 10 ratings; May require you to supply your own Hugging Face GPT-2 API key; Works only inside ChatGPT, not other writing apps; Autocomplete is Tab-based and fairly basic; no long-form generation [Profile (Markdown)](https://openaitools.app/tool/complete-ai.md) ## PromptBase PromptBase occupies the 'prompt layer' of the AI stack. As generative models became widely available, the hard part shifted from access to knowing what to type, and PromptBase turned that gap into a marketplace. Buyers get tested wording that reliably produces a particular result; sellers get paid for prompt engineering work they would otherwise give away. The catalogue is broad rather than deep in any single niche. There are categories for art styles, portraits, product shots, logos, icons, apparel designs, marketing copy and even prompts intended to help build small apps or landing pages. Each listing is tied to a specific model family, which matters because a prompt tuned for one image model often behaves differently in another. As a marketplace, PromptBase's value depends on its community. Sellers are incentivised by revenue share, which keeps fresh prompts coming, while buyers rely on sample images and seller reputation to judge quality before purchasing. The model is paid rather than free, and the site runs behind standard bot protection. **Pricing & Plans:** Paid marketplace. Most prompts are sold individually at low per-item prices set by their creators, with subscription options available for buyers who want ongoing access or credits. Pricing is not disclosed on the public page and may vary by listing. - **Curated prompt catalogue:** Thousands of ready-to-use prompts organised by model and by output type, from illustration styles to marketing copy. - **Model-specific sections:** Listings are grouped by the model they were built for, so you can filter to the tool you actually use. - **Sample output previews:** Each prompt is shown with example outputs, making it easy to judge the style before spending anything. - **Creator seller programme:** Anyone can upload prompts for sale and earn revenue share on every copy sold. - **Pay-per-prompt or subscribe:** Low per-prompt pricing plus buyer subscription options cover both occasional and high-volume users. **Strengths:** Saves time you would otherwise spend on trial-and-error prompt writing.; Sample images make quality easier to judge before buying.; Organised by model, so findings map to the tools you already use.; Creators can monetise prompt work directly. **Limitations:** There is no free tier for buying prompts - you pay per prompt or subscribe.; Quality and usefulness vary between sellers, so results depend on the individual listing.; A prompt that works well in one model is not guaranteed to behave identically elsewhere.; Popular prompts are widely sold, so exclusivity is limited.
