Keyworddit vs QuestionDB in 2026: A free single-subreddit scraper vs a paid multi-source question engine
Keyworddit pulls vocabulary from one subreddit at a time for nothing. QuestionDB pulls questions from Reddit, Quora, and Google's own PAA boxes, but the useful data sits behind a $9.99/month Solo plan.
Keyworddit
QuestionDB- Keyworddit only mines Reddit comment threads. QuestionDB combines Reddit, Quora, Google People Also Ask, and People Also Search into a single question database.
- Keyworddit is free with no search limit beyond the 10,000-subscriber subreddit requirement. QuestionDB's free tier caps out at 5 searches per month; regular use requires the $9.99/month Solo plan.
- QuestionDB adds keyword difficulty and CPC data on paid plans, plus an AI Outline Generator and AI Content Analysis. Keyworddit has none of these; it only returns a keyword list with volume attached.
- Neither tool offers API access at any plan tier, so both are strictly browser-based research tools with no automation path.
- Keyworddit's search volume comes from Grepwords, which the tool's own site flags as older data. QuestionDB's volume, difficulty, and CPC figures are only available once you leave the free tier.
Keyworddit and QuestionDB both mine Reddit for real audience language, but that is roughly where the overlap ends. Keyworddit is a single-page, single-source tool: type in a subreddit with 10,000 or more subscribers and it returns the terms people actually used in comment threads, each with a monthly search volume figure from Grepwords, at no cost and with no account. QuestionDB widens the net to Reddit, Quora, Google People Also Ask boxes, and People Also Search results, then layers search volume, keyword difficulty, and CPC data on top, plus an AI Outline Generator for turning a question into a content brief. That breadth is not free past five searches a month; the Solo plan at $9.99/month is where QuestionDB actually becomes usable for regular work. Keyworddit stays free forever but never leaves Reddit and never adds a metric beyond volume.
The tools at a glance
Keyworddit
Extract real keywords from Reddit subreddits with monthly search volume data, completely free
Keyworddit does one job and does it without asking for an email address: point it at a subreddit with 10,000 or more subscribers and it scans the comment history for the terms people actually use, attaching a monthly search volume figure through a Grepwords integration. There is no seed keyword to type, no search limit to track, and no plan to upgrade to.
Every result includes a context link that opens a Google search combining the keyword and the subreddit name, useful when a term surfaces without obvious context. Results export to CSV, so the list feeds cleanly into whatever tool handles competition or difficulty scoring next, since Keyworddit itself does neither.
The trade-off is scope. Keyworddit only ever looks at one subreddit at a time and only ever looks at Reddit. There is no Quora data, no PAA data, no difficulty score, and nothing resembling a content brief. It is a five-minute research detour, not a workflow.

QuestionDB
Find low-competition keywords by mining questions from Reddit, Quora, SERP PAA, and People Also Search
QuestionDB starts from questions rather than seed keywords, pulling from Reddit threads, Quora answers, Google People Also Ask boxes, and People Also Search results in a single search. That multi-source approach surfaces phrasing patterns that a volume database alone tends to undercount, since it captures how people actually ask things across four different platforms rather than one.
Paid plans add search volume, keyword difficulty, and CPC data next to each question, which turns a raw list into something you can actually prioritize. The AI Outline Generator then takes a chosen question and produces a structured brief with suggested headings, and AI Content Analysis checks existing pages against SERP competitors for coverage gaps.
The catch is the free tier: five searches a month is enough to sample the data quality for your niche but not enough to run real research. The Solo plan at $9.99/month for 100 searches is where QuestionDB starts earning its keep, and there is no API at any tier, so everything happens in-browser.

Which should you choose?
KeywordditQuestionDBQuestionDBKeywordditQuestionDBKeywordditThe honest comparison here is depth of source versus depth of scoring. Keyworddit only ever looks at Reddit, but it does so for free and without a search cap, which makes it a reasonable first pass on any topic. QuestionDB looks at four sources instead of one and attaches volume, difficulty, and CPC to the results, but that full picture is locked behind the $9.99/month Solo plan; the free tier's five searches a month barely qualify as a trial. Neither tool replaces a full keyword platform, since neither has an API or competitive data beyond the question itself.
Bottom line
Start with Keyworddit when a Reddit community is your only research target and budget is zero; there is no reason not to check it first. Move to QuestionDB's $9.99/month Solo plan once you need Quora and PAA data alongside Reddit, plus difficulty and CPC scoring to prioritize what to write. Running both in sequence, Keyworddit for raw Reddit vocabulary and QuestionDB for the multi-source, scored version, covers more ground than either tool does alone.
Frequently asked questions
Is Keyworddit or QuestionDB better for finding real user questions?
QuestionDB is better for finding real user questions across multiple platforms, since it pulls from Reddit, Quora, Google People Also Ask, and People Also Search rather than Reddit alone. Keyworddit only extracts keywords and phrases from a single subreddit's comment threads, so it surfaces vocabulary rather than fully formed questions.
Is QuestionDB worth $9.99 a month when Keyworddit is free?
QuestionDB is worth the $9.99 Solo plan if you need question data from Quora and Google PAA in addition to Reddit, plus search volume, difficulty, and CPC scoring attached to each result. If your research need is limited to how one specific subreddit talks about a topic, Keyworddit's free extraction already covers that without any subscription.
Does Keyworddit have keyword difficulty scoring like QuestionDB?
No, Keyworddit only returns a keyword list with a monthly search volume figure attached; it has no difficulty, competition, or CPC data at all. QuestionDB adds keyword difficulty and CPC on every paid tier starting at $9.99/month, which makes it the better choice for prioritizing which questions are worth targeting.
Can QuestionDB's free plan replace Keyworddit for casual research?
Not really, since QuestionDB's free tier is capped at 5 searches per month, which is enough to sample data quality but not enough for ongoing research. Keyworddit has no comparable search limit and stays free indefinitely, so for casual, repeated Reddit-focused research it remains the more practical free option.
Do either Keyworddit or QuestionDB offer an API?
No, neither tool offers API access at any plan level. Keyworddit exports results to CSV and QuestionDB exports to CSV and image formats, but both require manual work in the browser rather than programmatic access to the underlying data.
