Frequently Asked Questions

SDK.ac offers eight free browser-based prompt and text tools. Seven assemble requests from your fields and fixed instructions; Leading-Sentence Summarizer extracts opening text. The tool guides explain these local functions and show reproducible examples. None of the eight tools calls an AI model.

Seven tools produce prompts for you to review and copy to a separate assistant. They do not translate, draft emails, explain code, generate images or hashtags, or revise your text themselves. Leading-Sentence Summarizer is the exception: it returns an opening excerpt and word-count statistics directly, without using a model.

Paste your source text and select source and target languages. The tool puts those values into an English request that asks for only the translation. There are no separate formality, glossary, or tone settings. It does not detect the language. Swap exchanges the language choices while keeping the input text.

It matches chunks ending in a period, exclamation mark, or question mark and keeps the first chunks. Short retains up to two; Medium takes thirty percent rounded up, capped at five; Long takes half rounded up, capped at ten. It retains at least one chunk and uses the whole input if nothing matches. It does not rank importance.

Enter a task, optionally add context, and choose a style. The tool combines them with a fixed expert-assistant opening and closing request. There are no dedicated role or output-format controls: put any needed requirements into your text fields and review the assembled instructions.

It combines your subject with fixed style and mood phrases and a quality-word suffix. The result is text to adapt for a separate image service. The page does not render images, set dimensions, or provide a negative prompt field; words such as 8k are copied text, not enforced rendering settings.

It wraps the snippet in a code fence labelled with the selected language and adds a fixed Beginner, Intermediate, or Advanced explanation request. It does not detect the language, execute code, or analyze bugs. Any explanation comes from the separate assistant you choose and needs checking against the code.

Choose a type and tone, enter the topic, and optionally provide a recipient. The tool assembles a request plus a fixed checklist for a greeting, body, closing, and signature placeholder. It does not write the email, attach files, or send messages. Check any later draft before sending it yourself.

It combines your topic, platform, and count with fixed platform tips and formatting instructions. It does not generate candidate tags or fetch trends, popularity, or engagement data. Some tips contain counts that can conflict with your selection. Inspect and edit the request before using it in another service.

It prepares an editing request for text you already have. Choose improvement, grammar correction, simplification, formal tone, or casual tone. One fixed instruction is placed before the unchanged input, followed by a request for the revised version without explanations. No corrections or inline changes are made here.

Yes. We claim no ownership over prompts or text you create with the tools, and you may use them personally or commercially at your own responsibility. Note that the copyright status of AI-generated content varies by country, similar output may be generated for other users, and the third-party AI service you paste a prompt into may apply its own terms to the generated result. See Article 9 of our Terms of Service.

The local builders combine your input with fixed wording, and the summarizer copies opening chunks. Neither verifies facts. Responses from a separate AI service also need review. Treat every result as a draft: read it critically, check facts and numbers, and edit before you use it. Our tool guides describe the typical failure modes of each task so you know what to check.

A hallucination is when an AI model states fabricated information with complete confidence — invented citations, non-existent API functions, wrong dates, made-up statistics. It happens because language models predict plausible text rather than retrieve verified facts. The risk is highest when you ask for specific facts, sources, or figures, and lowest when the model transforms text you provided (translating, summarizing, rewriting). Always verify names, numbers, quotes, and references independently.

No — not without qualified human review. AI translation and summarization are excellent for understanding, drafting, and internal communication, but contracts, court documents, medical information, visa paperwork, safety instructions, and financial filings need a professional. An error in these contexts can have serious consequences, and AI models produce fluent-sounding text even when they are wrong, which makes errors hard to spot.

SDK.ac produces the same local output for the same input and settings. Separately used language models can vary their responses: they sample from a probability distribution over possible next words, so the same prompt can yield different phrasings or structures on each run. This is normal. If you need consistency, make your prompt more specific (exact format, length, terminology), or regenerate a few times and pick the best result.

Key ones: (1) training cutoff — models do not know about events after their training data ends, unless they have web access; (2) bias — models learn from human text and can reproduce social and cultural biases; (3) arithmetic and logic — models can make calculation and reasoning mistakes while sounding confident; (4) context limits — very long inputs may be partially ignored; (5) instruction drift — subtle requirements in long prompts are sometimes missed. Our per-tool guides explain how to mitigate each of these.

Advertising is what allows every tool and guide on SDK.ac to stay free, with no account, no subscription, and no usage limits. We serve ads through Google AdSense and keep placements moderate so they do not interfere with using the tools.

Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) to show ads based on your visits to this and other websites. You can opt out of personalised advertising in Google's Ads Settings at https://www.google.com/settings/ads, and opt out of many other vendors at https://www.aboutads.info/choices. Where required by law, a consent banner lets you refuse advertising cookies before any are set. You will still see ads after opting out, but they will not be tailored to your interests.

No. Tool inputs are processed in your browser and are never shared with advertising systems. Ad cookies relate to page visits, not to the content you type. Blocking ad cookies or using an ad blocker does not break the tools, since they run entirely client-side.

It is processed in your browser, on your device. The tools build their output locally; your input is never transmitted to, logged by, or permanently stored on our servers — there is no server-side database of user text. When you clear the input or leave the page, the text is gone. Full details are in Section 3 of our Privacy Policy.

Not by us. Your text reaches an AI model API only at the moment you yourself copy a generated prompt and paste it into a third-party assistant such as ChatGPT, Claude, or Gemini — and from that point the provider's own privacy policy governs how it is transmitted and retained. If we ever add a tool that calls an AI API directly, we will say so clearly on the tool page before you submit anything, send your text over an encrypted connection solely to generate your result, and never store it permanently.

No. We store no accounts (there is no sign-up), no tool inputs, and no generated outputs. Your text is never used to train, fine-tune, or evaluate any machine-learning model, by us or on our behalf. The only data we handle is aggregated analytics (page views, approximate country, browser type) and standard advertising cookies, as described in our Privacy Policy.

Almost everything lives only in your own browser: tool inputs exist only in page memory, and your theme/language preferences sit in localStorage. Clearing your browser's site data for SDK.ac removes all of it. For anything else — for example deleting an e-mail you sent us — write to [email protected] and we will handle it within the statutory deadlines.

Yes, completely free — no account, no subscription, no paid tier, and no usage caps on our side. The site is funded by advertising. Note that the third-party AI assistant you paste prompts into may have its own free-tier limits (message caps, model restrictions), which are governed by that provider, not by us.

SDK.ac works in all modern browsers — Chrome, Edge, Safari, Firefox, and Chromium-based browsers — on desktop and mobile. The interface is responsive, so the tools are fully usable on phones and tablets. We recommend keeping your browser up to date; very old browsers may not render the tools correctly.

Once a tool page has loaded, the prompt-building logic runs locally in your browser, so brief connection drops usually do not interrupt your work. You do need a connection to load pages initially and, of course, to use any third-party AI assistant with the prompt you generated.

E-mail us at [email protected]. Bug reports are most useful with your browser name and version and the steps to reproduce the problem. We read every suggestion, and several tools on the site started as user requests. We aim to reply within a few business days.
