Overview

QuestionDB draws question and conversation ideas from Reddit and Quora, alongside real-time sources including People Also Ask, People Also Search, and SERP. Its keyword tools add search volume, difficulty, competition, CPC, search intent, SERP analysis, and competitor keyword data, giving content planners more to weigh than a list of prompts alone.

Results can be inspected in Table, Card, or Tree view, then exported as CSV or a tree image. That range supports both structured keyword work and visual topic exploration. The homepage also presents AI Outline & Meta, AI Content Analysis, and an AI Keyword Extractor. No named third-party software integrations are described, so teams relying on a connected toolchain should not assume one is available.

QuestionDB is made by a company based in London. Its privacy policy says personal information is not sold, traded, or rented, though it may be shared with service providers or in specified legal and business circumstances. The policy describes technical and organizational safeguards but does not guarantee absolute security. Support is available through a contact form.

Key features

Question discovery and keyword context

Finding questions across community discussions and search results is useful when a content brief needs audience phrasing as well as conventional keyword measures. Search volume, difficulty, competition, and CPC help assess potential topics, while search intent, SERP analysis, and competitor keywords add further context. These metrics make the product more useful for prioritizing ideas, though the limited monthly search counts constrain how many topics can be assessed on lower plans.

Views, exports, and AI tools

Table, Card, and Tree views let users approach the same results as a data list or a topic structure. CSV export is suited to spreadsheet work; a tree image is a more direct way to share a visual map. The named AI tools cover outlining and metadata, content analysis, and keyword extraction. Those are useful additions to a research workflow, but the plan details do not say how their use is metered or what each tool can do.

Pricing

QuestionDB is freemium, with monthly billing for its paid tiers and search quotas that rise by plan. The free tier allows 5 searches/month, enough for occasional exploration but not sustained research. Payment is processed through Paddle, which accepts Visa, Mastercard, American Express, Discover, PayPal, Google Pay, and Apple Pay.

Plan	Price	Monthly searches	Published inclusions
Free	0.00 USD per free	5	Searches
Solo	9.99 USD per month, billed $9.99/month	100	Search volume, keyword difficulty, CPC, CSV and image export
Business	29.99 USD per month, billed $29.99/month	400	Search volume, keyword difficulty, CPC, CSV and image export
Enterprise	69.99 USD per month, billed $69.99/month	1000	Search volume, keyword difficulty, CPC, CSV and image export

Solo is the practical entry point for one person who needs recurring research and the listed keyword metrics and exports. Business raises the quota to 400 searches/month for heavier workloads, while Enterprise reaches 1,000/month. The higher tiers buy capacity rather than a stated change in feature set; none has a published seat count, so teams should not infer multi-user access from the names. All paid tiers are billed monthly, and the free tier's five-search cap is a meaningful constraint for anyone comparing many topics.

Platforms

QuestionDB is available on the web. No mobile or desktop app platform is stated.

Who it's for

It is a good fit for content creators, SEO practitioners, and small businesses who want question-led topic ideas and keyword measures in one web workflow, especially when exports and topic-tree views are useful. It is a weaker fit for researchers who need many searches on a free plan, teams that require confirmed seats or named integrations, or users looking for a native mobile platform.

Pros and cons

Pros: Combines questions from search and community sources, helping content planners find audience-led angles.
Pros: Search volume, difficulty, competition, CPC, intent, SERP analysis, and competitor keyword data add decision context to ideas.
Pros: Three result views and CSV or image export accommodate both spreadsheet analysis and visual sharing.
Cons: The free plan's 5 searches/month is too small for regular topic research.
Cons: The published paid tiers scale search quotas, but do not distinguish themselves by stated feature set or seat allowance.
Cons: Web is the only stated platform, and no named third-party integrations are described.

Verdict

Choose QuestionDB if your content work starts with questions and you want keyword metrics plus flexible ways to inspect and export results. Its strongest case is that combination in a web tool; its main drawback is the strict search ceiling on free and the quota-based paid tiers. Readers who need only occasional ideas can start free, while regular researchers should match their expected volume to Solo, Business, or Enterprise before committing.
