To chat with a file in Sparkian, start a conversation, choose a model, attach the file from the + (Add tools and actions) → Upload files menu (or drag it into the browser), then ask a specific question. Include the scope and the format you want back—such as a table with page numbers—and check important answers against the source file. Sparkian, formerly Geekflare Chat, supports document, spreadsheet, code, web, and image formats, but file and image handling can vary by model.
How to upload a file and ask a useful question
- Start a conversation and select a model. Available models and their file capabilities may differ.
- Attach the file. Select + (Add tools and actions) → Upload files, or drag the file into the browser window. Wait for its file indicator before sending your question.
- Ask for a defined result. Specify what to find, the scope, and the output format. If you need evidence, request page numbers, section names, or both.
- Follow up in the same conversation. The file and recent conversation history can remain in context as you refine the request. Sparkian’s memory and context documentation explains how recent history is used.
A broad request such as “Summarize this document” can produce a surface-level overview. A narrower prompt gives the model a clearer task, though it does not guarantee that every relevant detail will be found.

Prompt examples by document type
- Contract: “List every obligation, deadline, and penalty clause in this agreement. Include the section number for each.”
- Financial filing: “Extract the revenue figures, growth percentages, and projections. Return a table with metric, value, and page number.”
- Research paper: “Describe the methodology and limitations acknowledged by the authors. Check whether the conclusions appear to contradict the data, and cite the relevant sections or pages.”
For legal, financial, or research decisions, verify quoted figures, clauses, and citations in the original file. A model can miss material or give an incorrect page or section reference.

Can Sparkian read images or charts in a PDF?
Sparkian’s documentation says attachments can support visual understanding, depending on the selected model. The Geekflare guide’s author reports that image interpretation varied across models; in that guide’s example, GPT-5.6 handled text alongside visual elements, including charts and diagrams embedded in a PDF. That is the guide author’s reported experience, not a guarantee that every model will interpret every chart or image correctly.
If a chart matters, ask about it explicitly and request the page number, labels, units, and relevant values. Compare models in the same conversation if the result is unclear, then inspect the original visual before relying on extracted figures.

Which model should you use for a long PDF or other file task?
The Geekflare guide, updated September 12, 2026, reports the following recommendations from its author’s comparisons using the same files across Sparkian models. Treat them as task-specific observations rather than an independently validated benchmark or a promise of current availability; model labels and access may change.
Outdated Drivers Are Slowing You Down

| Long-PDF summaries and cross-referencing multiple files | Claude Sonnet 4.6 | Guide author’s reported result; verify against your own files. |
| Table extraction and image description | GPT-5.4 | Guide author’s reported result; verify against your own files. |

For your own work, compare outputs on a representative file and check whether the selected model supports the file and task you need. Do not assume one model is best for every document, chart, or question.

How to reuse files across conversations
If you refer to the same sources repeatedly, Sparkian’s Knowledge base lets you add files or text notes once and reference them in chat. Open Library → Knowledge base, add the source, then use Add from Library in a chat; the documentation also lists /library as a way to access it. See the official Knowledge base instructions.
When adding a source, choose its visibility deliberately: Private makes it visible only to you, while Workspace makes it available to people in the workspace. Knowledge base storage depends on plan.

Do uploads use more Sparks, and what are the file limits?
Attachments add tokens to a prompt. Sparkian says the starting Spark cost shown in the model panel is an estimate, not a fixed price for the request; actual use depends on the message, generated response, retained chat history, and attachments. Large files and longer conversations can therefore increase usage. See Sparkian’s Sparks explanation.

Paid-plan file-count and size limits and one-year chat history are as listed on that pricing page when checked; confirm the live page before choosing a plan or preparing a large upload. The pricing listing does not specify a Sparks recurrence period for paid plans, so do not assume a monthly allowance from those figures alone.
What to check before uploading confidential material
Data-use treatment can depend on the selected model and provider. Sparkian’s welcome documentation notes this model-specific caveat; review Sparkian’s current privacy policy and the selected model or provider’s applicable terms before uploading confidential, personal, or regulated documents. Do not treat a general statement about one provider as a blanket guarantee for every model available in the workspace.
