They cannot browse those sites. A local tool collects the reviews and hands them to your agent. Here is the setup, and what it returned on a real field service product.
Can Claude read App Store reviews? Not on its own. Claude and ChatGPT cannot reliably read G2, Capterra or App Store reviews unless a local tool collects them first, saves them with their source, and hands them to your agent over MCP. BigIdeasDB Desktop does this. In a November 2, 2026 BigIdeasDB Desktop run, it pulled about 350 of Jobber's newest App Store and Google Play reviews in one check, grouped the complaints, and showed which app versions the crashes clustered in. A plain fetch of a G2 page from the same machine returned a 403.
If you typed “summarize the worst G2 reviews of this tool” into a chat window, you already know how it goes. You get a polite paragraph built from the five reviews the model could see, plus a few things it half remembers from training. Nothing links back to a real review, and you cannot tell which parts are invented.
Reviews are the best free source of product gaps there is. Reviewers name the feature that is missing, the price that stung and the bug that cost them a job. This guide shows how to get that text in front of Claude or ChatGPT without copy-pasting, and then shows a real run so you can see what comes back, including the part that did not work.
Review sites are built to stop automated readers, and chat assistants are automated readers. Four things go wrong, in this order.
The same wall is why Reddit became hard for assistants this year. Our own Reddit connector tool returned HTTP 403 on November 2, 2026 for a plain search, which is the problem we cover in how to give Claude access to Reddit and connecting ChatGPT and Claude to Reddit. Reviews are the same story with a different logo.
| Approach | G2 / Capterra | App Store / Google Play | Source links |
|---|---|---|---|
| Ask the chat to browse | Blocked or partial | A few visible reviews | No |
| Paste 60 to 100 reviews by hand | Works, slow | Works, slow | Only if you keep them |
| Local tool plus MCP (Desktop) | Read through your own browser | Direct, no login | Yes, every review |
Install a local research app, connect your agent to its MCP server, add the product, then ask in plain English. The steps below use BigIdeasDB Desktop for Mac and Windows. The full walkthrough is in the Desktop help guide.
Download the installer, sign in to activate it, then pick your agent in Settings. Desktop runs one local MCP server, so Claude Code, Claude, Cursor, Codex and the ChatGPT desktop app can all connect. It uses the AI plan you already pay for. One licence covers up to 3 computers. See the live price on the Desktop pricing page.
App stores need nothing. G2, Capterra, TrustRadius and Trustpilot are read through your own browser, so Desktop needs its browser extension connected first. This is the step that matters most, and the one that tripped our run (see below). It is also the reason this works where cloud scrapers fail: the requests come from your IP, at a normal pace, in a browser you are already signed in to.
Add the product by name, then run a find. Desktop searches each review site and returns ranked hits (strong, likely, weak). Link the right page for each site. Software products map to one page per site, apps map to one listing per store.
A check fetches reviews. For software sites it pulls the lowest-rated pages and the newest pages, one page every few seconds. For stores it pulls the newest reviews. The next check is cheaper because it only fetches what is new.
Now the agent has structured reviews instead of a web page. Ask for themes, then for the raw reviews behind each theme, then for an idea card. The prompts section below has wording that works. If you want the idea-finding method on top of this, read how to find SaaS ideas from negative G2 and App Store reviews.
We ran the whole workflow on Jobber, a field service and invoicing product, on November 2, 2026. We picked it because founders in this category sell to people who live in the mobile app and write blunt reviews. We added Jobber to a Desktop project twice, once in the Software Reviews Lab and once in the App Reviews Lab, and ran the steps above.
Two results came back and one did not. The app side worked end to end. The G2 and Capterra side failed at the search step, and we kept that in the article because it is the honest picture of the setup.
Desktop found the App Store listing and the Google Play listing, fetched the newest reviews, and counted 350 of them with a 2.96 star average, against store ratings of 4.8 and 4.4. The find step returned the listing as a “likely” match with 21,000+ ratings on the App Store. We linked both stores and ran one check. It took about 24 seconds as estimated.
| Store | Reviews fetched | Average of fetched | Store's own rating |
|---|---|---|---|
| App Store | 50 | 3.08 | 4.81 (21,000+ ratings) |
| Google Play | 300 | 2.94 | 4.42 (6,900+ ratings) |
| Combined | 350 | 2.96 | n/a |
The gap matters. Of the 350 fetched reviews, 135 were one star and 134 were five stars, so the distribution is a barbell, and 48% were rated 1 to 3 stars. The store rating is a lifetime average. The newest reviews show what is happening now, which is what a founder hunting for gaps needs. Read the 2.96 as a recency signal, not as the true rating.
Desktop counts themes with rule-based phrase lists, so the app does the counting and the AI does the reading. Here is what it counted.
| Theme | Reviews | Share | Example line (store review) |
|---|---|---|---|
| Bugs and slowness | 36 | 20% | “This app constantly crashes, runs extremely slow, and their picture process is a nightmare.” |
| Missing features | 24 | 13% | “Can't log in since the update.” |
| Price and plans | 18 | 10% | “$60/month for the lowest tier. Come on.” |
| Contracts and billing | 11 | 6% | “if you dont like the app you cant cancel it and get any money back you are stuck with it for the full year.” |
| Hard to use | 7 | 4% | “User interface, scheduling, monthly planner is not intuitive and slow app response.” |
Reliability leads. The “missing features” bucket is noisy, because the phrase list catches words like “can't” and picks up login failures. That is the reason to follow a theme to its raw reviews. Desktop returns the review keys behind each theme, so your agent can open the 36 reliability reviews and confirm what they say.
The request side was smaller and clearer. Reviewers asked for a better mobile app (6 mentions), customization such as custom invoices and arrival messages (5), and more integrations (4). On the integration theme the examples were blunt, such as a review telling small businesses that want professional invoices to “just use QuickBooks.”
App reviews carry the app version, and that turns a vague “it crashes” into a release you can name. We pulled the 40 newest reviews rated 2 stars or lower. They ran from version 6.87.0 to 6.100.0. We counted the ones that describe a freeze, crash, restart or failed load. Ten of the 40 did, and nine of those ten named versions between 6.90 and 6.96. One review on 6.100.0 was about an account blocked after a payment dispute, which is a different problem.
The timeline view gave reviews per month and the average rating for the last 12 months. The sampled average moved between 2.4 (February 2026) and 4.13 (April 2026), and sat at 2.74 in September and 3.24 in October. Monthly counts ran from 16 to 52 reviews. With one app and a newest-first sample, treat that as a prompt for a question, not a trend line.
Reading the 40 low reviews ourselves surfaced a cluster the rule-based themes did not have. Four of the 40 were not about the product at all. They were about sales contact after a signup or trial. One reviewer said they had been called, texted and emailed “for TWO YEARS” after signing up to look at the app. Another asked to be removed from a call list a year earlier. A third complained about calls at 6AM. A fourth said the sales emails, calls and texts began as soon as the account was created.
That is a finding a founder could build on, for example a field service tool with no outbound sales pressure. It is also the reason we tell agents to read raw reviews after the themes. Counting finds what you already thought to look for. Reading finds the rest.
Small samples need a flag. Four of 40 is 10% of the newest low ratings in one app. It is a lead to check against another source, which is the next section.
The G2, Capterra, TrustRadius and Trustpilot searches all failed with “not connected” on November 2, 2026, so Desktop returned no software-site reviews for Jobber in this run. We ran the find step twice. Both times the four site searches ended with the same error, because the Desktop browser extension was not connected to this machine's browser. We did not work around it or invent numbers, and we are not publishing G2 or Capterra review counts for Jobber from this run.
That is the practical lesson. The app-store path is zero setup. The software-site path has one prerequisite: the browser connection. Once it is on, Desktop searches each site through your own browser, ranks hits by name match, and fetches the lowest-rated and newest pages at roughly one page every nine seconds per site. It also reports a site as unavailable, held by a check or blocked, instead of failing the whole job.
For the “with versus without” contrast, the without side is simple. The same G2 page that Desktop is built to read through a real browser returned a 403 to a plain fetch, so the agent would have had nothing to analyze.
Fresh reviews tell you what one product's users say today. The BigIdeasDB corpus tells you whether the complaint repeats across the whole category. Our research corpus holds 1M+ complaints and reviews. The review-heavy slices, read live on November 2, 2026, are below.
| Slice | Records | What it is |
|---|---|---|
| Low-rated App Store reviews (3 stars or less) | 99,000+ | Mobile complaints with AI analysis |
| Capterra pain points | 39,000+ | Extracted from software reviews |
| G2 processed insights | 9,000+ | Sentiment and pain summaries |
For the field service category the corpus gave a second, independent read. Capterra's Field Service Management category is rated high on competition and growing, with a sentiment trend marked declining. Jobber's own Capterra analysis shows a declining sentiment trend, with pricing as its weakest dimension and customer support as its strongest. The category's recurring systemic pain points include cumbersome integration with accounting tools (7 companies affected), poor mobile app performance during critical tasks (5 companies) and limited reporting and automation (7 companies).
Put the layers together and the picture holds. Desktop showed pricing, reliability and sales-contact complaints in the newest Jobber app reviews. The corpus shows pricing as Jobber's weakest Capterra dimension and mobile performance as a category-wide pain. Two independent sources pointing at the same problem is what turns a hunch into a lead. The same cross-check is how the Capterra review mining guide and the G2 review idea guide reach an idea.
Limits apply. Capterra category fields come from AI analysis of reviews and read as directional. The Capterra corpus is not complete: coverage stops partway through the alphabet in some categories. Use it to spot patterns, then confirm on live reviews.
The workflow has been done manually for years. These are real comments from r/SaaS threads that Google ranks for review mining, with usernames removed.
“We help SaaS companies and others with marketing and one of the things we do is review mining, where we copy at least 60-100 reviews from various platforms and run those through an LLM (liking Gemini more and more these days) with a detailed prompt (one is about 5 pages long) to extract customer sentiment, billing/cancellation issues, other friction points...” – r/SaaS
That is the copy-and-paste loop in one sentence. It works and it does not scale past one product.
“Tried something similar with G2 reviews and our NPS comments, was surprised how many ‘too expensive’ notes were actually ‘couldn't figure out how to do X within the trial period.’” – r/SaaS
This is why reading raw reviews beats counting a “price” theme. A price complaint can be an onboarding complaint, and only the text tells you.
“the g2/capterra vs trustpilot gap is so real and i dont think enough founders realize those reviews aren't just for humans browsing anymore, theyre also getting pulled into AI answers when ppl ask if X is good or ask for alternatives to X.” – r/SaaS
Review sites now feed AI answers too, which raises the value of reading them first-hand.
“Negative G2 reviews are basically pre-filtered ‘please fix this and I'll pay you’ signals.” – r/SaaS
“How did you get the reviews? Crawled the site?” – r/SaaS, under a post about analyzing 150k negative G2 reviews
The last one is the whole problem in six words. Everyone wants the analysis. Few have a clean way to get the reviews. That is the gap a local collector fills. We found these threads on r/SaaS. We did not find a thread in r/ClaudeAI or r/ClaudeCode that solved it, which fits the open search results for this topic.
Ask for counts first, raw text second, a decision last. Each prompt below assumes your agent is connected to Desktop.

| Source | What we pulled | Limitation |
|---|---|---|
| BigIdeasDB Desktop, App Reviews Lab | Overview, themes, timeline and raw low-rated reviews for one app | Newest reviews only, about 350 of tens of thousands. Theme counts are phrase matches. Tools reported slightly different totals (350, 400, 550), so we quote the overview figure. |
| BigIdeasDB Desktop, Software Reviews Lab | Find step on G2, Capterra, TrustRadius, Trustpilot | All four searches failed with “not connected”. No software-site reviews were collected. |
| Plain page fetch of a G2 reviews URL | HTTP status and body | One attempt on one URL. Shows a block, not how often it happens. |
| BigIdeasDB database (Supabase, read-only) | Corpus counts, Capterra category and company analysis | Counts rounded. Capterra fields are AI-derived and the scrape is incomplete in some categories. |
| Reddit threads (r/SaaS) | Five comments from review-mining threads | Small, self-selected sample. Not representative of all founders. |
One product, one category, one day. The Jobber numbers describe Jobber's newest app reviews on November 2, 2026, not every field service app. Run the same steps on the product you care about before you act on any of it.
BigIdeasDB Desktop collects G2, Capterra and app store reviews on your own computer and gives them to the AI you already use. Try it on your own product's reviews.
Not by itself. G2 and Capterra sit behind bot checks, logins and paginated lists, so a chat request either fails or returns a summary of a few visible reviews. In our November 2, 2026 test a plain fetch of a G2 reviews page returned a 403. A local tool that collects the reviews and passes them to Claude over MCP works.
Not on its own, but yes once the reviews are collected for it. App Store and Google Play reviews come from public store endpoints, so in a November 2, 2026 run BigIdeasDB Desktop pulled about 350 of Jobber's newest reviews in one check (24 seconds estimated) with no account and no browser, then handed them to the agent with stars, date and app version.
Install a local research app that exposes review tools through MCP, point Claude Code at it, and ask for the product by name. With BigIdeasDB Desktop you add the product, link its Capterra page, run a check, then ask Claude Code for themes and the lowest-rated reviews. Capterra is read through your own browser, so it must be connected first.
BigIdeasDB Desktop is the best fit for G2 review analysis because it reads G2 through your own browser and IP, saves each review with its source link, and counts complaint, request and praise themes itself so your AI is not guessing. It also covers Capterra, TrustRadius, Trustpilot, the App Store and Google Play in one project.
BigIdeasDB Desktop. It fetches App Store and Google Play reviews with no login, groups them into complaint, request and praise themes, shows reviews per month with the average rating, and keeps the app version on every review. In our Jobber run that showed which app versions the crashes clustered in.
Yes. BigIdeasDB Desktop runs one local MCP server, and the ChatGPT desktop app, Claude, Claude Code, Codex and Cursor can all connect to it. You use the AI plan you already pay for, so the reviews are analyzed by whichever agent you open.
Reviews are public, and a local tool that reads them at a normal pace through your own browser behaves like you reading them. Check each site's terms for your use case. Keep the research internal, quote reviews with attribution to the platform, and do not republish full review text.
You cannot count on getting every review. In a November 2, 2026 BigIdeasDB Desktop run, one app yielded about 350 of its newest App Store and Google Play reviews, while the App Store alone lists 21,000+ ratings. For G2 and Capterra, Desktop pulls the lowest-rated and newest pages first. Read the stored count before you trust a percentage.
