PICK A METHOD

Different questions need different research modes

A good AI tool does more than search. It helps you choose a method that fits the decision you need to make.

01Breadth first

Scan

Map a new topic quickly. Collect definitions, players, themes and open questions before going deep.

02Decision ready

Compare

Set the same criteria for every option and produce a matrix you can defend in a meeting.

03Evidence heavy

Investigate

Follow a company, claim or market signal through primary sources, filings and conflicting accounts.

04Many sources

Synthesize

Turn papers, notes or saved tabs into a literature map, brief or clear next-step recommendation.

THE RESEARCH PROTOCOL

Shape the work before the agent starts

Tabbit keeps the research plan visible so you can tighten the scope, change the method or add a source rule before the browser does the heavy lifting.

Scope the question

Turn a broad prompt into one decision, a time window and a clear audience.

Set source rules

Choose primary sources, independent coverage, language and freshness requirements.

Sequence the passes

Start with a map, follow the gaps, cross-check claims and stop when the brief is complete.

Review the output

Pick the format that makes the next action obvious: brief, matrix, map or memo.

Tabbit shows a deep research task with a visible execution plan beside live search results — Keep the protocol and live source trail in the same browser window.

OUTPUT TEMPLATES

Choose an output your team can use

The best deep-research tool is measured by what happens after the report. Start from the format your reader needs.

01 / FORMAT

Research brief

A concise answer with context, key findings, caveats and linked next steps.

02 / FORMAT

Comparison matrix

Shared criteria, visible trade-offs and a recommendation that survives scrutiny.

03 / FORMAT

Literature map

Themes, methods, disagreements and the gaps worth investigating next.

04 / FORMAT

Decision memo

Options, evidence, risks and a proposed action for a real business decision.

Tabbit displays a daily research paper board with summaries and an AI digest in the side panel — Collect source material first; let the final format guide the synthesis.

WHY TABBIT

A research tool that stays close to the source

Tabbit is a downloadable AI-native browser, so your protocol, model choice and working tabs stay together instead of being scattered across extensions and chat windows.

Use the page you are reading

Reference open pages or uploaded files with @ context rather than copying fragments into a separate chat.

Choose the right model

Switch models for fast scanning, careful comparison or long synthesis before you run the task.

Save a playbook

Turn a successful research protocol into a reusable Skill for the next market scan or literature review.

Tabbit model selector offers several AI models beside an input that can reference pages or files — Choose a model and bring source context into the same prompt.

Tabbit compares responses from several AI models in parallel columns — Compare model perspectives when the question needs it.

TOOL SELECTION RUBRIC

Factor	Question	Good signal
Scope control	Can I review and edit the plan?	A visible, editable protocol before execution.
Source quality	Can I set boundaries and inspect pages?	Primary-source rules plus live context.
Method fit	Does it support comparison and synthesis?	More than one search-and-summary recipe.
Output fit	Can I shape the final deliverable?	Briefs, matrices, maps and memos—not one generic answer.
Repeatability	Can I run the workflow again?	Saved skills, workspaces and an archive of source context.

FAQ

Questions people ask about AI tools for deep research

What is an AI tool for deep research?+

It is an AI system that can plan a multi-step investigation, browse or read many sources, compare findings and produce a structured output. The useful distinction is whether you can control the scope, sources and deliverable—not simply whether it generates a long answer.

What is the best AI tool for deep research?+

The best tool depends on the job. Look for editable planning, source controls, a method that matches your question, a useful output format and a way to repeat the workflow. Tabbit brings those choices into a browser with live tabs and model selection.

Can I use an AI research tool for literature reviews?+

Yes. Start with a synthesis or scan protocol, set a date and source boundary, then ask for themes, methods, disagreements and gaps. Keep the original papers open so you can verify important claims.

Is there a free AI tool for deep research?+

Tabbit is free to download on macOS and Windows. Availability and model limits can vary by region, so check the current product experience when you start a task.
