Choosing AI tools for documents, news and crypto data

Start with the task. A whitepaper summary needs passages you can locate; a news update needs a search that actually ran; price analysis needs timestamped data. A product name or subscription price cannot stand in for those checks.

Edited by PromptDeck · Content corrected 2026-09-25.

This is an editorial selection guide grounded in official product information. We do not publish a complete set of common inputs, raw outputs and grading records for these seven products. We have therefore withdrawn the earlier scores, stars, two-editor testing claims and percentage advantage. The exercises below are ways to run your own comparison, not tests we claim to have completed.

Define the job first

For documents, begin with a reliable original. For news, specify a date range and primary sources. For calculations, supply data you can recompute independently. Product order is for navigation, not ranking. We omit fixed monthly prices, context limits and winner labels because plans, models and interfaces change.

What supports this guide

Official pages support the product capabilities described here. Suggested workflows are editorial choices. Availability does not establish answer quality or access for every account. Our common evidence policy is on the methodology page (Chinese).

Record the date and setup

Official pages checked: 2026-09-25. When making your own comparison, record the product, interface, model shown, plan, whether search actually ran and the input date. One answer without that context cannot represent an entire product.

Compare the same material yourself

Give each candidate the same whitepaper passage and ask for allocation, vesting conditions and page references. Use one official announcement to check event date, scope and unknowns. Use one data table to request the formula and units. Keep failed and incomplete responses rather than selecting only the best attempt. Split long documents into sections if needed; a successful upload does not prove every page was read.

Inspect evidence, without a composite score

Check whether each citation exists and supports the claim; whether numbers, units and dates agree; whether conditions are missing; whether uncertainty is acknowledged; and whether the next step is usable and risk-aware. We assign no weights or total score. Publishing an accuracy figure would require a separate sample, grading rubric, valid and invalid outputs, and a reproducible calculation.

Seven product starting points

ChatGPT

Consider ChatGPT for organizing research material. Its official documentation describes web search and source links. Check that the particular answer used search, then open its citations. The old claim that searching requires a paid subscription should not guide your choice.

Claude

Claude supports web search. Enable it where the interface offers a switch; some newer interfaces invoke it automatically, and managed workspaces may require administrator permission. Look for search activity and citations. Searchable web pages are not a continuous market feed or proof of the price at which an order can execute.

Perplexity

Perplexity describes its service as search-backed answers with citations. It can be a starting point for a source list. Open the originals and distinguish announcements from reporting or promotional posts; this guide makes no speed or accuracy ranking.

Gemini

If you already use Gemini, try the same material for summarization, table reading and source location. Confirm accepted files and limits in your current interface first. A capacity advertised for an older model does not establish what your current plan accepts.

Grok

When considering Grok, check which search sources the current interface can access. For an answer citing X, verify the account, post date, original post and repost relationships. A handful of posts cannot establish market-wide sentiment or exclusive data coverage.

DeepSeek

When using DeepSeek to explain a concept, request the original terminology and a source. For new events, verify that the current interface offers search and actually used it. Do not assume web-client features are available through an API.

Kimi

Before using Kimi on a document, check that the file imported completely and request source locations. Compare how the answer handles the same fact in the body, appendices and tables. Long-input support is not a guarantee against omissions.

Match the checks to the task

Whitepapers: try two accessible products and compare citations and omissions before writing style. News: use an interface that can search now, restrict the event dates and return to the project or regulator announcement. Charts: treat the screenshot as reading material and obtain the underlying prices and time range separately. Chinese explanations: check terminology and reasoning; fluent prose is not evidence of accuracy.

Checks every tool needs

If an answer contains missing citations, stale data, unread PDF sections or inconsistent units, stop using that conclusion. Ask for unresolved points; if they remain unresolved, return to the source document, block explorer or data provider. Two models can repeat the same mistaken source. Never paste private keys, seed phrases, passwords or trading API secrets into a chat.

Before paying for another subscription

Choose one recurring research task and record the time you spend checking and correcting the output. Existing access may be enough. Only consider another plan after identifying a specific file, usage or feature limit; check the official checkout for local pricing, tax and cancellation terms. We provide no verified fixed-price subscription bundle.

Keep Binance data and execution separate

Separate research from execution. For Binance data, verify the pair, market type, timestamp and quote unit, then recompute from a trusted source. A model's current-price claim is not an order-price reference. See the Binance features guide for related context. This page supplies neither automatic execution code nor validated profitable signals.

Frequently asked questions

Which tool is most accurate?

This page has no publicly reproducible comparison dataset, so it publishes no accuracy ranking. Check citations, numbers and omissions on your own material.

Can Claude access the web?

Claude supports web search. Actual use depends on the interface, settings and account permissions. Inspect search activity and citations; market prices still need an independent data source.

Why remove illustrative scores?

Illustrative numbers can still look like test results. This guide uses sources, task checks and limitations rather than substituting a score for evidence.
