You can save time by summarizing long PDFs for free with Anthropic’s Claude AI chatbot. So, the next time someone sends you a 100-page document that you don’t have hours to read, you can just follow this guide and get a quick summary.
Claude allows you to upload PDFs, as well as some other files, such as DOCX, CSV and TXT, directly to it. Then, by typing a command such as “Summarize PDF,” you can get a clear, concise summary of PDFs across a wide range of subject matter.
For example, when Claude was fed two different publicly available PDFs of F. Scott Fitzgerald’s “The Great Gatsby,” it returned two different summaries of the novel. Each response included the main plot points. Claude may return different summaries for the same PDF even when given the same command, but each summary is still accurate.
Claude worked well for other content, too.It returned a clear bulleted list of revenue, net income and other financial information from Microsoft‘s most recent earnings report, all of which were correct. It meant that I didn’t have to dig through the earnings results to find the high-level numbers I was looking for.
Pro tip: There are other commands you can type instead of just ‘summarize.” Try phrases such as “Tell me the important information in this” and “Recap this for me” to get the highlights of the document. The summaries that are returned may differ but will still contain accurate information.
The free version of Claude has limitations. It can’t process PDFs larger than 10 megabytes and it has a limit that appears to be five summaries roughly every four hours.
Here’s how to use Claude AI to summarize text:
Just attach the PDF and tell Claude to summarize it by typing ‘Summarize PDF.’

Shares of the enterprise artificial intelligence company C3 AI fell 14% in extended trading on Wednesday after it announced fiscal first-quarter results and the appointment of Stephen Ehikian as its new CEO.
C3 AI reported $70.3 million in revenue for the quarter, down from $87.2 million during the same period last year. The company’s GAAP net loss widened to an 86-cent loss from a 50-cent loss a year ago.
Ehikian is a long-time tech executive who built two companies that were both acquired by Salesforce, C3 AI said. C3 AI said Ehikian assumed the new role on Sept. 1.
C3 AI kicked off a search for a new chief executive in July after its former CEO, Thomas Siebel revealed that he was diagnosed with an autoimmune disease earlier this year that resulted in “significant visual impairment.”

“C3 AI is one of the most important companies in the AI landscape and enterprise software, with a platform and applications that are unmatched,” Ehikian said. “I am confident that we will be able to capture an increasing share of the immense market opportunity in Enterprise AI.”
The company has had a rocky few months since Siebel’s diagnosis.
Shares plunged in August after C3 AI announced disappointing preliminary financial results and a restructuring of its global sales and services organization.
Siebel said in an August statement that sales results during the quarter were “completely unacceptable.” He attributed the performance to the “disruptive effect” of the reorganization, as well as his ongoing health issues.

Salesforce issued disappointing guidance on Wednesday, even as earnings and revenue topped estimates for the fiscal second quarter. The stock dropped 4% in extended trading.
Here’s how the company did in comparison with LSEG consensus:
Earnings per share: $2.91 adjusted vs. $2.78 expected
Revenue: $10.24 billion vs. $10.14 billion expected
Revenue increased 10% from $9.33 billion a year earlier, according to a statement. Net income rose to $1.89 billion, or $1.96 per share, from $1.43 billion, or $1.47 per share, a year ago.
For the fiscal third quarter, management called for $2.84 to $2.86 in adjusted earnings per share on $10.24 billion to $10.29 billion in revenue. Analysts polled by LSEG had been looking for $2.85 per share on $10.29 billion in revenue.
Salesforce maintained its full-year revenue outlook but now sees higher earnings. The company is targeting $11.33 to $11.37 in adjusted earnings per share on $41.1 billion to $41.3 billion in revenue. The consensus estimate from LSEG was $11.31 in earnings per share and $41.2 billion in revenue. The forecast in May included $11.27 to $11.33 in adjusted earnings per share.
Salesforce has fallen out of favor on Wall Street this year due to an extended stretch of meager revenue growth, which has been stuck in the single digits since mid-2024. While the company regularly touts its investments in artificial intelligence and the advancements in its software and systems, it hasn’t been lifted by the AI boom in the same way as many of its tech peers.
Going into Wednesday’s report, Salesforce was down 23% for the year, lagging behind all but one stock in the Dow and trailing all other large-cap tech companies.
The ratio of Salesforce’s enterprise value to its free cash flow has reached a 10-year low because of fears of disruption from AI, according to analysts at Jefferies, who have a buy rating on the stock. Salesforce is trying to counter the pressure by selling its Agentforce AI software that can automate the handling of customer service questions.
During the fiscal second quarter, Salesforce said it was planning to increase the cost of some products and announced its intent to acquire data management software company Informatica for $8 billion.
Executives will discuss the results with analysts on a conference call starting at 5 p.m. ET.

Figma Inc. shares surged as much as 229% after the design software maker and some of its shareholders raised $1.2 billion in an IPO, with the trading valuing the company far above the $20 billion mark it would have reached in a now-scrapped merger with Adobe Inc.

Figma shares plunged 13% in extended trading on Wednesday after the design software company reported results for the first time since its IPO in July.
Here’s how the company did in comparison with LSEG consensus:
Earnings per share: breakeven
Revenue: $249.6 million vs. $248.8 million expected
Revenue increased 41% year over year in the second quarter from $177.2 million a year earlier, Figma said in a statement. The company provided a preliminary estimate of $247 million to $250 million in a July regulatory filing. CNBC isn’t including a profit estimate because it’s Figma’s first earnings report.
Net income totaled $846,000, compared with a loss of $827.9 million in the second quarter of 2024. The company’s adjusted operating income came to $11.5 million, after Figma provided a prior estimate of $9 million to $12 million.
For the third quarter, Figma forecast revenue of between $263 million and $265 million, which would represent about 33% growth at the middle of the range. The LSEG consensus was $256.8 million.
The company sees between $88 million and $98 million in adjusted operating income for the full year and a little over $1.02 billion in revenue. The revenue range implies about 37% growth and is above the $1.01 billion LSEG consensus.
Last year, Figma picked up more revenue from customers as it sold them access to Dev Mode, which helps software developers to implement designs that designers create in the company’s software. That momentum is putting a damper on revenue growth for the third quarter, Figma co-founder and CEO Dylan Field said in an interview.
In the second quarter, Figma announced Figma Make, which uses artificial intelligence to compose app and website designs based on a user’s descriptions, and Figma Sites, which turns designs into working websites. The company also acquired vector graphics startup Modyfi and content management system startup Payload.
Figma has yet to start fully charging for AI products, but says it has built the underlying costs into its model. The company is not providing a forecast for third-quarter adjusted operating income.
A number of software vendors have faced pressure this year due to concerns surrounding AI and whether it will displace business. Field said he’s not seeing that play out internally and that, if anything, the role of designers will only become more critical.
“I think that the more that software becomes easier to build with AI, the more that people are going to see that that human touch is needed,” Field said. He acknowledged that Figma has been adopting so-called vibe-coding tools for AI-driven software development.
Figma reported a 129% net retention rate, a reflection of expansion with existing customers. The figure was down from 132% in the first quarter.
Following its IPO, Figma expects a share sale lockup to expire for 25% some employees’ stock after market close on Sept. 4. Investors holding just over half of Figma’s outstanding Class A stock have agreed to an extended lock-up that will expire in August 2026 for about 35% of their shares.
Field said he wanted to provide clarity for investors.
“That’s something that I think is valuable information,” he said.
On Wednesday the company’s stock closed at $68.13. The company priced shares in its IPO at $33, and saw the stock pop to $115.50 in its debut.
Executives will discuss the second-quarter results with analysts on a conference call starting at 5 p.m. ET.
