Glimpse vs Keyworddit in 2026: A free trend-forecasting overlay vs a free Reddit keyword miner
Both tools have genuinely free entry points, but they extract completely different signals. One turns Google Trends into absolute search volume and 12-month forecasts. The other mines Reddit comment threads for the language a specific community actually uses.
Glimpse
Keyworddit- Keyworddit is completely free at every tier with no account required. Glimpse's free tier covers the Chrome extension only, with Trend Alerts, channel breakdown, and forecasting reserved for an unpublished Pro plan.
- Keyworddit is limited to subreddits with 10,000 or more subscribers; smaller communities return no results at all. Glimpse has no equivalent audience-size restriction since it works from aggregate Google Trends data.
- Glimpse's forecasting model claims 95%+ backtested accuracy on 12-month predictions. Keyworddit has no forecasting feature; it surfaces present-tense keyword frequency from Reddit comments, not future trajectory.
- Keyworddit sources its search volume data from Grepwords, which the tool's own site flags as worth cross-referencing against more current sources. Glimpse sources absolute search volume directly from Google Trends.
- Neither tool offers a standalone self-serve API. Glimpse gates API access to Enterprise customers only, and Keyworddit has no API, integrations, or automation options at all.
- Glimpse's trend discovery platform spans 50+ categories with channel breakdown across 8 platforms. Keyworddit covers exactly one source: Reddit comment threads within a single subreddit at a time.
- Keyworddit includes context links that open a Google search combining the keyword and subreddit name, so you can validate usage quickly. Glimpse has no equivalent context-link feature; its interface is built around volume and trend curves rather than source verification.
Glimpse and Keyworddit are two of the few genuinely free tools in keyword research, and neither one is trying to be a full SEO platform. Glimpse's free Chrome extension replaces Google Trends' relative index with real search volume and growth data, then upsells Trend Alerts, channel breakdown, and forecasting through an unpublished Pro plan. Keyworddit stays free at every tier: type in a subreddit with 10,000 or more subscribers, and it scans that community's comment history for the terms people actually use, pairs each one with a monthly search volume figure from Grepwords, and exports the whole list to CSV with no account required. Glimpse answers where a topic is heading across the wider internet; Keyworddit answers how one specific community talks about a topic right now. The two rarely compete for the same research task, which makes them easier to use together than most tools in this comparison series.
The tools at a glance
Glimpse
Google Trends supercharged with absolute search volume, trend forecasting, and channel breakdown across 132+ countries
Glimpse's free Chrome extension rewrites the Google Trends interface in place, adding absolute monthly search volume and growth percentages next to the relative index Google already shows. A "People Also Search" panel expands a single keyword lookup into related terms with the same volume data attached, all without leaving the Google Trends page.
The standalone trend discovery platform goes further: 120x more trend entries than any competitor across 50+ categories, each with channel breakdown showing where a topic is gaining traction across TikTok, Reddit, YouTube, LinkedIn, and four more platforms. The forecasting model claims 95%+ backtested accuracy on 12-month projections, with public early calls on trends like pickleball and Perplexity AI.
The free tier stops short of Trend Alerts, full channel breakdown, and forecasting, which sit behind an unpublished Pro plan requiring a signup or sales call. API access is Enterprise-only. Unlike Keyworddit, Glimpse works from aggregate search and social signal data rather than a single community's raw language, so it will not tell you how a specific audience phrases a problem.

Keyworddit
Extract real keywords from Reddit subreddits with monthly search volume data, completely free
Keyworddit does one narrow thing and does not charge for it: type in a subreddit with at least 10,000 subscribers, and it scans that community's comment history for the terms people actually use, then attaches a monthly search volume figure to each one via a Grepwords integration. The premise is that Reddit comments carry more authentic, less filtered language than a keyword database infers from aggregated query logs.
Every result comes with a context link, a Google search combining the keyword and the subreddit name, so you can quickly check how a term is actually used before building content around it. Results export to CSV, which is how most people are meant to use the tool: a free first pass before running the shortlist through Ahrefs, Semrush, or a broader keyword platform.
The limitations are the point rather than a flaw. There is no API, no saved projects, no history, and no forecasting of any kind, and the 10,000-subscriber cutoff means niche subreddits below that threshold return nothing. Grepwords as a volume source is also older than what current premium tools use, so treat the numbers as directional.

Which should you choose?
GlimpseKeywordditGlimpseGlimpseGlimpseKeywordditKeywordditBoth tools are free at the entry point, but they extract different kinds of signal and rarely answer the same question. Glimpse works from aggregate search behavior and social platform signals to tell you where a topic is heading across the wider internet, backed by a specific, checkable forecasting accuracy claim. Keyworddit works from the raw language of one Reddit community to tell you how real people are phrasing a problem right now, with no attempt at forecasting or breadth. Glimpse is the stronger choice for spotting and forecasting a rising topic; Keyworddit is the stronger choice for finding the specific words a niche audience already uses.
Bottom line
Install Glimpse's free Chrome extension for real search volume and 12-month forecasting on any topic you already track in Google Trends. Run Keyworddit against a relevant subreddit if the topic has a real Reddit community with 10,000 or more subscribers, since the authentic vocabulary it surfaces will not show up in either Glimpse or a standard keyword database. Neither tool replaces a full keyword research platform for CPC or competition data, so both work best as a free first pass before a paid tool.
Frequently asked questions
Are Glimpse and Keyworddit actually free, or is that a limited trial?
Both are genuinely free at their core, not time-limited trials. Glimpse's Chrome extension provides limited absolute search volume and growth data directly inside Google Trends with no expiration, while Keyworddit is free at every tier with no account, credit card, or usage limit mentioned on the site.
Why does Keyworddit only work for subreddits with 10,000 or more subscribers?
Subreddits below that threshold typically do not generate enough comment volume for Keyworddit to extract statistically meaningful keyword frequency data. This is a deliberate filter built into the tool, so searching a smaller niche subreddit returns no results rather than an unreliable, sparse list. Glimpse has no equivalent size restriction since it draws from aggregate Google Trends data rather than a single community's comments.
Which tool is better for forecasting whether a trend will keep growing?
Glimpse is purpose-built for this question. Its forecasting model strips out seasonal noise and projects a topic's trajectory 12 months out, claiming 95%+ backtested accuracy with public early calls on trends like pickleball and Perplexity AI. Keyworddit has no forecasting capability at all; it only reports the keywords a community is currently using along with a present-tense monthly search volume figure.
Where does Keyworddit's search volume data come from, and is it reliable?
Keyworddit sources its volume figures from Grepwords, which the tool's own site compares to Google Keyword Planner but recommends cross-referencing against more current sources for accuracy. Glimpse pulls its absolute search volume directly from Google Trends data, which is generally considered a more current and widely trusted source for directional search demand.
Can I automate either tool with an API?
Not easily. Glimpse offers an API, but only on its unpublished Enterprise tier, which requires a sales conversation to access. Keyworddit has no API, integrations, or automation options of any kind, since it is designed as a single-page, manual-use lookup tool.
Which tool should I use first when researching a new content topic?
Start with Keyworddit if the topic has an active subreddit with 10,000 or more subscribers, since it surfaces the authentic phrasing a community already uses before you write anything. Layer in Glimpse afterward to check the topic's absolute search volume and 12-month trajectory, which tells you whether the demand behind that phrasing is actually growing or already past its peak.
