Quick verdict
Julius AI is a workspace that analyzes data files and databases by writing and running Python or R in a cloud container, and it also makes charts, reports, slides, websites, images and short videos. Free gives 75 one-time welcome credits plus 25 daily credits on Julius Lite only, and deletes your files after 1 hour of inactivity. Plus is $20 a month, or $16 a month billed yearly, $192 a year paid up front by our calculation, with 2,000 credits a month plus 100 daily credits, 16 GB of RAM and 7-day file storage. Pro is $45 a month, or $37 a month billed yearly ($444 a year by our calculation), with 5,000 credits a month, 32 GB of RAM, unlimited parallel agents and 3 scheduled runs. Max ($200 a month, 25,000 credits) and Ultra ($500 a month, 70,000 credits) are higher credit tiers of Pro that add the Julius 1.2 Ultra model. Julius's Terms say prices exclude sales and other taxes.
Ownership is simple on paper: Julius's Terms treat your input and output as your content, claim no ownership of it and do not restrict your right to use it, with no plan restriction stated. On training, the privacy policy says Julius does not train its own models on personal information, but your content is shared with AI technology providers unless you opt out by emailing privacy@julius.ai. There is no setting for it.
The main things to check before you pay are model access and file retention. Julius's pricing page says Plus includes models such as Claude Opus 5.5, while its models page lists third-party models only for Pro and above. Credits are spent per task, and the cost depends on the model, tools and complexity, so how far a plan goes is not stated in tasks. This verdict rests on what Julius documents, not on our tests, which we have not run yet.
Strengths and limits
Strengths
- Analysis that runs real codeOn every plan, Julius writes Python or R and runs it in a cloud container on CSV, Excel, JSON, Parquet, SQLite and SPSS files and on connected databases. Paid plans get 16 GB of RAM on Plus and 32 GB on Pro, Max and Ultra.
- Data sources beyond uploadsFree connects Google Drive, OneDrive and SharePoint. Plus and above add Snowflake, BigQuery and Postgres on the pricing table, and Julius's docs also cover MySQL, SQL Server, Supabase, Google Ads and Meta Ads. You can also link a Google Sheet into a chat as a data file.
- You keep your outputJulius's Terms say your input and output are your content, Julius claims no ownership, and nothing restricts your right to use and exploit it. No plan restriction is stated, so this applies to Free as well.
- Slides and websites from the same chatThe AI Presentation Maker builds a deck from a prompt, a file or an analysis and exports PowerPoint, PDF, PNG, HTML or Google Slides. The Website Builder publishes to a public Julius link on all plans. Both are marked Limited on Free.
- Models from several companies on Pro and upPro, Max and Ultra get a Model Selector with Julius's own models and third-party models from OpenAI, Anthropic, xAI, Meta and Moonshot AI. Max and Ultra add Julius 1.2 Ultra.
Limits
- Free deletes your filesPlan limit. On Free, files are kept for up to 1 hour of inactivity and there is no file storage. Paid plans keep files for 7 days of inactivity, and no storage size is given.
- Plus model access: Julius's pages disagreeConflict. The pricing page says Plus includes "Access to frontier AI models like GPT-6.1 Sol and Claude Opus 5.5", but the models page lists third-party models for "Pro, Max, Ultra, and Business" only. The two pages also name different OpenAI models.
- Credits do not map to tasksPlan limit. Free gets 25 daily credits that reset at 00:00 UTC and do not accumulate. Paid plans get monthly credits plus 100 daily credits, but Julius says cost per task depends on the model, tools and complexity, so no plan states how many analyses it covers.
- No full-chat exportWorkflow limit. Julius says full-chat export as PDF, DOCX or Jupyter Notebook is no longer available. Generated files download from the Files page, and a copy of your account data can be requested by email.
- Gaps in what is documentedNot verified. Julius does not state a context size for its plans. Voice conversation, watermarks on generated images or video, and whether the app shows ads are not documented. Pricing promises a custom Julius domain for websites, while the docs say custom domains may require external hosting.
Based on what Caesar Labs Inc. documents for each plan, not on our tests.
Who it suits
A good fit if you
- Analyzing spreadsheets and data files by asking in plain language
- Querying Snowflake, BigQuery or Postgres from a chat, on Plus and above
- Turning an analysis into a slide deck you can export to PowerPoint or Google Slides
- Comparing answers from models of several companies, on Pro and above
Look elsewhere if you
- Keeping files between sessions on Free: they are deleted after 1 hour of inactivity
- Writing code in your own editor: Julius has no code editor or repository tools
- Working inside Excel or Google Sheets: no add-in is documented
- Exporting a whole chat as a document or notebook: no longer available

A use is listed when at least one plan documents every feature a task needs. Answer quality is a separate question: see below.
Using it day to day
Julius runs on the web and in an iOS app. Its pages disagree on Android: the FAQ says the Android app is currently unavailable in Google Play, while another page mentions iPhone and Android apps. You work in a chat: upload PDFs, Word documents, spreadsheets, images or code files, or link a Google Sheet, and Julius searches the web and, according to its pricing page, answers with citations. Plus and above can also use a Live Browser that operates a real browser and pauses for logins and CAPTCHAs.
Everything is paid in credits. Free has 25 daily credits plus 75 one-time welcome credits. Plus has 2,000 a month, Pro 5,000, Max 25,000 and Ultra 70,000, each plus 100 daily credits; yearly billing grants the year's credits up front (24,000 on Plus). Max and Ultra are not separate cards: you pick them in the credit menu on the Pro card. Creative tools include images up to 3840 px on the long edge in PNG, JPEG or WebP, video clips of 1 to 15 seconds at 480p or 720p, and MP3 narration with 13 voices, up to 4,096 characters per generation. Custom Agents have been sunset in favor of custom instructions and skill files.
Privacy, data and ads
Julius's privacy policy says it does not train its own models on personal information. Your content is shared with AI technology providers, and to opt out you email privacy@julius.ai; there is no setting for it. You can request a copy of your account data by email. Whether Julius shows ads is not verified: no page says any plan has ads, but the privacy policy says device data may be used "to ensure relevant advertising is presented within the Services". On Free, uploaded files are deleted after 1 hour of inactivity; on paid plans, after 7 days.

- Make sense of documents that disagree
- Research a current question within a date window
- Edit an article without changing its facts
- Turn project notes into a report that agrees with itself
- Implement a small specification
- Refactor code without changing what it does
- Make a picture that follows a detailed brief
- Put exact text into a graphic
- Change one thing in a picture and nothing else
- Make a short clip that follows a brief
- Make a song that sings your lyrics exactly
- Read a script with names, numbers and abbreviations
- Design a logo with an exact name
Getting started
- Start on Julius Free with a small file and a question you already know the answer to. Download anything you want to keep, because Free deletes files after 1 hour of inactivity.
- Before you upload anything confidential, email privacy@julius.ai to opt out of sharing your content with AI technology providers.
- If you need a database connection or longer file storage, choose Plus at $20 a month. If you need a specific third-party model, confirm in the Model Selector which plan includes it, because Julius's pages disagree for Plus.
- Watch the credit balance on your first tasks, since cost depends on the model and tools, and move up to Pro or its Max and Ultra tiers only if you run out.
- Compare Julius with other research and data tools on our tools page, and read how we check vendor claims.
