Beste AI-agent voor onderzoek: gerangschikt op geaccepteerd bewijs, niet op snelheid.

Wat het bewijs laat zien: Perplexity Computer starts from Perplexity's search-and-citation workflow and adds multi-step execution, connectors, generated files and scheduled tasks. Early hands-on reviews find it most convincing for supervised research and report creation, while also flagging retrospective rather than predictable credit costs, weak visibility during some runs and the risk of spending credits after a vague brief sends the task in the wrong direction.

Wat te testen en prijs: Use questions with known primary sources and record claim-level citation coverage, unsupported claims, credits, connector success, clarifying behaviour, intervention points and verification time. Inspect the final sources rather than accepting a polished answer at face value.

Wie het moet kiezen: Best for research-led work where current web evidence and traceable sources matter most. Avoid it for high-risk unattended actions or tightly budgeted workloads until task-level credit use becomes predictable in your own sample.

Wat het bewijs laat zien: Manus is strongest as a delegated project agent rather than a faster chat window. Officially it can research, work in a browser and sandbox, produce documents, slides and websites, and continue longer jobs in the background. Independent hands-on reports praise the visible task plan and useful finished artefacts, but also report crashes, blocked sites and uneven results on ambiguous tasks.

Wat te testen en prijs: Run five real jobs and record credits spent—including failed attempts—completion rate, factual corrections, blocked logins or CAPTCHAs, export quality and reviewer minutes. Credit use can vary sharply with task complexity, so the subscription price alone is not a useful comparison.

Wie het moet kiezen: Best for people who regularly delegate bounded research-to-deliverable projects and are willing to supervise them. Avoid making it the only production workflow until your own test shows stable completion, predictable credit use and acceptable exports.

Wat het bewijs laat zien: ChatGPT Work extends the familiar ChatGPT environment into longer-running research and knowledge-work tasks with connected tools and finished documents, spreadsheets, presentations and sites. ChatGPT has the largest body of general user feedback here: users consistently value its speed, accessibility and broad capability, while agent-mode reports still describe usage limits, occasional wrong turns and the need to supervise consequential actions.

Wat te testen en prijs: Test the exact connected apps your team uses, not a demo workflow. Record task-limit consumption, connector failures, citation corrections, spreadsheet and presentation repair, context that must be repeated, and whether recurring work completes without intervention.

Wie het moet kiezen: Best for teams already working in ChatGPT that need one broad assistant across research, writing, coding and office deliverables. Do not pay for it solely as an autonomous worker if ordinary ChatGPT already covers the real workload.

Wat het bewijs laat zien: Genspark combines research with specialist agents for slides, sheets, documents, design and communications. Reviewers commonly highlight how quickly it turns a brief into a polished, editable deliverable. The trade-off is breadth over consistency: source selection, formulas, formatting and multi-step execution still need review, and regeneration can consume a meaningful share of the allowance.

Wat te testen en prijs: Give it the same cited research brief, spreadsheet and presentation used for every competitor. Check every material claim and formula, then record credits, regenerations, export editability, template compliance and the time required to repair the final files.

Wie het moet kiezen: Best for consultants, marketers and operators who repeatedly turn web research into slides, sheets or shareable documents. It is a weaker choice when the job requires dependable access to gated systems, strict audit trails or unattended execution.

Wat het bewijs laat zien: Claude Cowork is aimed at file-heavy and cross-app knowledge work: reading local files and connected sources, synthesising large source packs, revising documents and carrying multi-step work into deliverables. The product is newer than Claude chat, so independent Cowork-specific evidence is still limited; official capability claims are clearer than long-term reliability data.

Wat te testen en prijs: Use a representative folder with messy files, conflicting versions and a strict output template. Record source attribution, missed files, long-document consistency, permission prompts, formatting repair, usage limits and whether scheduled or connected-app work completes as expected.

Wie het moet kiezen: Best for document-intensive teams that value careful synthesis and already prefer Claude's writing and context handling. Treat it as a supervised pilot—not a proven autonomous back office—until it passes repeated tests on your files and access controls.
