Otio

Your spreadsheets hold the most important data, but your AI tools couldn't read it. Analysts, finance teams and researchers live in two places at once. The reading and the writing happen in one set of tools. The numbers sit in a spreadsheet somewhere else. So to ask AI anything about that data, you export it to a PDF and lose the structure, or copy rows into a chat that quietly breaks the columns, or rebuild the table by hand. The data and the analysis never end up in the same room. Otio 2.0 now reads spreadsheets and data files directly, in the same workspace as your PDFs, articles and notes. Upload the file, ask questions across it alongside everything else you are working from, and get the data back as visualisations you can actually read, not just rows to scroll. It works across the formats people actually use: CSV, TSV, XLS, XLSX, XLSM, XLSB and ODS. The point is not one more upload button. It is that data extraction stops being a separate chore in a separate tool, and your numbers finally sit next to the sources that explain them.

Most research tools make you choose: chat with AI or build a chart. Otio does both in the same window. You upload a set of reports. Ask "chart the year-on-year figures across these three documents." A bar chart appears in the chat. Every data point cited back to the page it came from. No export to Excel. No separate visualisation tool. No tab-switching to check if the AI got the numbers right. The workflow most people run: ChatGPT for the question, then manually pull the data into Sheets, then Flourish or Datawrapper for the chart, then cross-reference back to the source to verify. Four tools, twenty minutes, and you still don't know if you missed a footnote. Otio collapses that into one ask. The data becomes visual without you leaving the conversation. Bar charts. Line charts. Comparison tables. All generated from your uploaded sources. All traceable to the exact page. This is what 200,000+ researchers mean when they say Otio handles the work other tools make you split across platforms. One workspace. Your sources. Any AI model. Visualisations that cite their work.

You built a note that synthesizes twenty sources into something coherent. Someone asks to see it. So you copy-paste into an email. Or a Google Doc. Or Slack. And now there are two versions. The one in Otio that you'll keep updating. The one you sent that's already stale. Most research tools trap your work inside the platform. You can export a PDF or copy text out, but the moment you do, it's disconnected. No live link back. No way for someone to pick up where you left off without starting over. Otio Notes work differently. Every note gets a shareable link. Anyone opens it in their browser. No account required to read. If they want to edit or build on it, they sign up right there and fork it into their own workspace. Your synthesis stays in one place. The link stays current. Sharing takes three seconds instead of three minutes of reformatting. A consultant sends a client brief. A PhD candidate shares a lit review with their supervisor. A journalist sends background research to an editor. Same mechanic: one link, readable immediately, forkable if they want to go deeper. The work you do in Otio doesn't have to stay in Otio. But it can live there, and you control who sees it and when. What's the last piece of research you had to copy-paste out of a tool just to share it?

NotebookLM is genuinely good. The audio overviews are excellent. The free tier is generous. But it locks you to Gemini. Even on paid plans. And you hit the source cap fast. 50 sources on free. 100 on Plus. 300 on Max. 600 on Business. Then you stop. Otio gives you every frontier model. ChatGPT, Claude, Gemini, Grok, Llama, DeepSeek. No source limits. Deep Research included. On every tier. One connected library instead of separate notebooks. Citations that trace to the exact page, not just a passage link. NotebookLM is great until you need a model that isn't Gemini, or your 51st source, or a citation formal enough for a court filing. Try it -> otio.ai 50% off Otio Go for 3 months with code GO50V2

If you have tried to do real research on your phone and given up, here is why. The ChatGPT app caps how many files you can upload per message and resets your library every session. NotebookLM has no real iPhone workflow; most AI research tools are desktop-and-web only. There is simply nothing to open. Otio is a native iPhone app: the same tool professionals use on desktop, built for the phone. Every AI model in one place: ChatGPT, Claude, Gemini, Grok, Llama, DeepSeek. No file upload limits. No source caps. Upload PDFs, articles, YouTube videos, podcasts and books, and chat across all of them at once. Every answer cites the exact page or timestamp - tap to open the original. Built-in document scanner. Share sheet from any app. Read Aloud. Spaces for organising projects. Everything syncs to desktop and web. Link in comments. https://otio.ai/mobile

You've collected 80 sources for a report. You haven't read them yet. Jenni AI is built for the moment you're ready to write - line-by-line autocomplete, citation formatting, plagiarism checker. Brilliant when you know what you want to say. Otio is built for the moment before that. When you need to synthesise across everything you've collected, pull structure from chaos, and figure out what the through-line even is. Different stages. Different tools. Jenni asks: "What's your next sentence?" Otio asks: "What's the pattern across all of this?" If you're writing one paper from 10 PDFs, Jenni's autocomplete is gold. If you're synthesising 100 sources before you start writing, that's an Otio job. Try it free → otio.ai → 50% off Otio Go for 3 months with code GO50V2

If you have searched "NotebookLM alternative" in the last six months, here is what you were actually looking for. NotebookLM works because it is source-grounded - every answer comes from the documents you upload. That is also why power users praise it. But it caps your sources, and gates you to Google's models. Otio is the same source-grounded architecture, no caps. Any model - Claude, GPT, Gemini. Any format - PDF, video, audio, web page, transcript. Full mobile parity with desktop. Every answer cites the exact passage in your sources and one click jumps to the highlighted paragraph in the original document. Deep search and web search are built in for when you need the open web. 200,000+ users across research, law, consulting, finance, and journalism use Otio for AI research without the hallucinations.
