Answer The Public vs QuestionDB in 2026: search autocomplete ideation vs Reddit and Quora question mining
Both tools turn a seed topic into a list of real questions, but they pull from different sources and land at very different prices. One starts at $20 a month with a bundled AI writer; the other starts at $9.99 a month with a sharper focus on community forums.
Answer The Public
QuestionDB- Answer The Public pulls questions from Google and Bing autocomplete. QuestionDB pulls from Reddit, Quora, Google People Also Ask, and People Also Search, a genuinely different and more community-driven data source.
- QuestionDB starts at $9.99/month for the Solo plan, less than half of Answer The Public's $20/month Starter tier, for a comparable volume of paid searches.
- Answer The Public bundles Composeo, a full AI article drafting suite, on every paid plan. QuestionDB's AI features stop at outline generation and content gap analysis; it does not draft complete articles.
- Neither tool offers an API at any plan tier, so neither one plugs into an automated research or content pipeline.
- Answer The Public's free account allows 3 searches a day, roughly 90 a month. QuestionDB's free tier allows only 5 searches a month total, a much tighter cap.
- QuestionDB includes keyword difficulty scores on paid plans; Answer The Public does not surface difficulty data at all, only search volume and CPC.
- Answer The Public documents support for more than 20 languages and country-level targeting. QuestionDB does not publish equivalent multi-language coverage details.
Answer The Public and QuestionDB both exist to answer the same question, what is someone actually asking about this topic, but they go looking in different places for the answer. Answer The Public draws from Google and Bing autocomplete, which reflects what search engines predict people will type next. QuestionDB pulls from Reddit threads, Quora answers, Google People Also Ask boxes, and People Also Search results, which surfaces language people use when they are genuinely asking each other for help rather than typing into a search box. Answer The Public has since expanded into a broader content tool with Composeo, its bundled AI article writer, while QuestionDB has stayed narrower and cheaper, adding an AI Outline Generator rather than full drafting. Price is the other big split: QuestionDB starts at $9.99 a month, less than half of Answer The Public's $20 Starter tier, though both cap their free plans tightly enough that you will want to upgrade fast if the data is useful.
The tools at a glance
Answer The Public
Autocomplete-driven question research bundled with an AI content creation suite
Answer The Public builds its question sets from Google and Bing autocomplete, organizing the results into questions, prepositions, comparisons, and alphabetical variants in a visual layout that is fast to scan for content angles. It is a search-engine-first view of intent: the questions reflect what people type into a search bar, not what they post in a forum.
Since the 2022 acquisition by NP Digital, the platform has grown past pure ideation. Composeo, bundled on every paid plan, takes a chosen question straight into a drafted article, with the monthly allowance scaling from 3 pieces on Starter to 30 on Business. Search volume and CPC data ship alongside the question data, giving a rough read on commercial value in the same screen.
The trade-off is cost and scope. At $20 a month for the Starter tier, it is more than double QuestionDB's entry price, and it has no keyword difficulty scoring or forum-sourced language, both of which QuestionDB covers. If your interest is specifically in what real people say to each other about a topic on Reddit or Quora, autocomplete predictions are a different, more search-engine-shaped signal.

QuestionDB
Question mining from Reddit, Quora, and SERP features at one of the lowest entry prices in keyword research
QuestionDB starts from a different premise than most keyword tools: instead of predicting what people search for, it mines what they actually ask in Reddit threads and Quora answers, then layers in Google People Also Ask and People Also Search data on top. That combination surfaces phrasing and sub-topics that autocomplete-based tools tend to miss, particularly for niche or community-heavy subjects.
Paid plans add search volume, keyword difficulty, and CPC data so you can prioritize which questions are worth writing about without opening a second tool. The AI Outline Generator turns a chosen question into a structured brief with suggested headings, and AI Content Analysis checks existing pages against SERP competitors to find coverage gaps, useful for refreshing old content as much as planning new pieces.
What it will not do is write the article for you. There is no full AI drafting the way Composeo provides, and no API at any tier, so it stays a research and briefing tool rather than a production one. At $9.99 a month for the Solo plan and 100 searches, though, it is one of the cheapest credible entries in question-based keyword research.
| Feature | Free Free | Solo $9.99/mo | Business $29.99/mo | Enterprise $69.99/mo |
|---|---|---|---|---|
| Searches per month | 5 | 100 | 400 | 1,000 |
| Search volume and CPC data | ✗ | ✓ | ✓ | ✓ |
| Keyword difficulty scoring | ✗ | ✓ | ✓ | ✓ |
| AI Outline Generator | ✗ | ✓ | ✓ | ✓ |
| AI Content Analysis | ✗ | ✓ | ✓ | ✓ |

Which should you choose?
QuestionDBQuestionDBAnswer The PublicQuestionDBAnswer The PublicAnswer The PublicThe two tools look interchangeable from the category page, but the data sources genuinely differ in a way that matters for content strategy. Answer The Public's autocomplete data reflects search engine prediction, useful for matching how people phrase queries in a search bar. QuestionDB's Reddit and Quora data reflects how people phrase the same underlying need when talking to other humans, which often surfaces more specific, more emotionally direct language. Price and AI depth are the other real divide: Answer The Public costs more but writes the article for you, QuestionDB costs less and stops at the outline.
Bottom line
Choose QuestionDB if budget matters and you want community-sourced question data plus keyword difficulty scoring for under $10 a month. Choose Answer The Public if you want a bundled AI writer that takes you from question to a finished draft, and you are comfortable paying at least double for that convenience. Content teams targeting topics with active Reddit or Quora communities, health, finance, relationships, and similar categories, generally get more distinctive angles from QuestionDB than from autocomplete predictions alone.
Frequently asked questions
Is QuestionDB cheaper than Answer The Public for question-based keyword research?
QuestionDB is significantly cheaper, starting at $9.99 a month for the Solo plan with 100 searches, compared to Answer The Public's $20-a-month Starter tier. The gap holds at higher tiers too: QuestionDB's Business plan is $29.99 a month versus Answer The Public's $99-a-month Growth plan, though the two are not offering identical feature sets at each price point.
Does QuestionDB pull questions from Reddit and Quora the way people describe it?
Yes. QuestionDB aggregates questions from Reddit threads, Quora answers, Google People Also Ask boxes, and People Also Search results in a single search, which is a genuinely different data source from Answer The Public's Google and Bing autocomplete approach. This tends to surface more community-specific phrasing than autocomplete-based tools.
Can QuestionDB write full articles the way Answer The Public's Composeo does?
No, QuestionDB stops at outline generation. Its AI Outline Generator produces a structured brief with suggested headings from a chosen question, and AI Content Analysis flags gaps in existing content, but there is no full article drafting feature comparable to Composeo, which is bundled on every Answer The Public paid plan.
Does either Answer The Public or QuestionDB offer an API?
Neither tool offers an API at any pricing tier. Both are entirely browser-based, so teams needing to pull question or keyword data into an automated content pipeline will need a third tool alongside whichever of these two they choose.
Which tool has keyword difficulty scores, Answer The Public or QuestionDB?
QuestionDB includes keyword difficulty scoring on all of its paid plans, starting at $9.99 a month. Answer The Public does not surface a difficulty metric at all; it shows only search volume and CPC data, so pairing it with a dedicated SERP analysis tool is necessary if difficulty scoring matters to your workflow.
Which free plan is more useful for testing, Answer The Public or QuestionDB?
Answer The Public's free plan is more generous in practice, allowing 3 searches a day, which works out to roughly 90 a month. QuestionDB's free tier caps at just 5 searches a month total, enough to get a feel for data quality but too thin to run any real research project before upgrading.
