PentraexEverything a student keeps rebuilding by hand in MS Word — cover pages, CVs, assignment and lab report formats — is free here, and stays free. Below that is the professional work I take on: mapping, analysis, research support and development.
Open any tool and use it straight away — the editor and the live A4 preview need no account. Downloading the PDF or PNG asks for a free account, which also saves your documents so you can finish them on your phone or the lab computer. No fee, ever, for the student tools.
Click any card and it opens straight away — no account to try it, and what you type stays in your own browser until you press Save. Signing in (free) is what turns on the downloads, saves your documents to your account and keeps the last ten versions of each one.
One map system for Bangladesh: explore the atlas, or make a study area, report, thesis or slide map. Several areas on one map (e.g. Jashore + Satkhira), 20+ layers from division to mouza, colour by population or 64 MICS indicators, your own shapefiles, PNG/JPG/PDF from A5 to A0. Free to compose and preview with the aljubaer.com watermark — downloads are locked until you buy: BDT 50 per clean map, BDT 500 unlimited for a year.
Open itTwenty-eight document types — academic CV, research CV, ATS resume, technical resume, consultancy CV for UN and the banks, the Bangladeshi সরকারি চাকরির বায়োডাটা and the বিবাহের বায়োডাটা — each opening with the section order that field actually expects. Seventeen print templates, ten themes, a worked example in English and Bangla for every type, real page-by-page preview, PDF and editable Word.
Open itThe cover page for an assignment, lab report, thesis or term paper. Now with all 178 UGC universities and their departments: pick yours and its own mark appears on the sheet, one click to hide it. Fourteen layouts, ten themes, or type every line yourself.
Open itThe twelve slides after the title slide — background, the research gap, objectives, study area, methods, results, limitations, conclusion — in the order a board expects, with a speaker-note box under each one and a Word handout for your supervisor.
Open itSix kinds of letter in English or বাংলা — job application, PhD or supervisor enquiry, internship, UN expression of interest, and the Bangladeshi সরকারি আবেদন in the order every office expects (বরাবর → বিষয় → জনাব → অতএব বিনীত প্রার্থনা → নিবেদক). Eight layouts, a worked example for each, PDF and editable Word.
Open itThe pages after the cover: numbered sections, tables, a reference list and a running footer — one print-ready PDF.
Open itAim, apparatus, theory, procedure, observation table, calculation, result, discussion and precautions — already in order.
Open itEvery page before chapter one — title page, supervisor certificate, board of examiners, declaration, acknowledgement, abstract, contents, lists of tables, figures and abbreviations, and a study area map page. English or বাংলা, 15 formats for Bangladeshi universities, free PDF and Word. Expert-formatted pack with a clean study area map from BDT 300.
Open itEverything a Teletalk or BPSC application asks for: photo 300×300 under 100 KB and signature 300×80 under 60 KB, cropped and compressed in your browser; your age on the circular date against the 32-year limit; your details written once with a copy button for every field; and the দরখাস্ত in বাংলা or English. Free to use on screen — clean JPG, PDF and Word downloads from BDT 49.
Open itSample size by Cochran, Yamane or Krejcie-Morgan with every step and the methodology paragraph in বাংলা and English; unions or wards drawn at random from the BBS 2022 census frame and opened on the map; a proposal in university, NU, research-grant or NGO format with work plan and budget; and a bilingual questionnaire that exports straight to KoBo Toolbox. Free to use — clean PDF, Word and XLSForm downloads from BDT 99.
Open itThe same details laid out 16:9 — export a PNG straight into PowerPoint or Google Slides.
Open itSemester GPA and cumulative CGPA on the 4.00 or 5.00 scale — or your department’s own — plus the number the next semester needs to hit your target. Exports as a clean A4 marksheet.
Open itPaste a DOI and it fills itself in from Crossref. APA 7, Harvard, IEEE, Vancouver and Chicago, with the in-text form beside every entry and a print-ready reference list.
Open itEvery document in the studio also comes out as a real .docx with proper heading styles and tables — because the department wants a file it can edit and the supervisor marks up in Word.
Open itSign in free and every cover, CV, assignment and slide is saved to your account — open it on your phone, the lab computer or a friend’s laptop, and roll back to any of the last ten versions.
Open itYour college is not on any list? Type the name, add your own logo, and get exactly the same quality of page.
Open itYour institution's logo loads automatically where we have it, and is remembered on this device either way.
Open itTen curated palettes, a custom colour picker and ten premium font pairings — re-skin any template live.
Open itType your institution, roll and supervisor once — every other tool opens already filled in.
Open itThe structure a Statement of Purpose actually needs — why this field, why this question, why this supervisor, why you, and what happens after. Each section carries the question an admissions committee is reading for, and a word budget. It does not write a word for you; that is the point, and it is what keeps this safe to hand to a university.
Open itProject work I take on directly. Tell me the scope and the deadline and you get a fixed quote back — no retainer, no agency in between.
Your dashboard kept alive after launch: hosting, data refreshes, uptime monitoring, small changes and a monthly note on what people actually used.
Disease mapping, cluster detection, environmental risk factors and outbreak-risk surfaces — built the way a journal reviewer expects, with the methods written up.
QGIS, Google Earth Engine, Python and R — as a self-paced course, a book, or a session for your team or department.
Ready datasets from the DataHub, or a dataset built to your area, period and variables, with a datasheet.
Flood, cyclone or fire extent from the latest usable satellite scene, back within 24 hours: GeoTIFF plus a one-page PDF with the method and an accuracy figure. Fixed price, no scoping call.
A working GEE script for your study area — NDVI, LST, flood extent, built-up change, rainfall — with the export set up and a session walking you through how to change it yourself.
Suitability and accessibility analysis, hotspot statistics, and web dashboards that stay live once they are handed over.
Thematic maps, land-cover and change detection, flood and salinity mapping, cartography fit for a journal or a report.
The repeating job done once and then run by itself: Python or GEE pipelines that fetch, clean, analyse and publish — scheduled, logged, and handed over with the code.
Interactive map portals, data platforms and the ordinary websites around them — built, hosted and documented.
Study design, cleaning and analysis, figures and tables that meet the journal's format, and the write-up around them.
Flight plan, processing and delivery: orthomosaic, DSM/DTM, contours and volume estimates, in the coordinate system your office actually uses.
One site, one page: flood history and depth, heat trend, salinity, erosion and exposure, every source named — written for a proposal deadline, not a research timeline.
Hand over the folder, get back a report: what is actually in it, the real projection, what is duplicated or unusable, what it would cost to fix — and the open formats that will outlive your current software.
KoboToolbox and ODK forms with skip logic and validation, enumerator training, and a clean dataset at the end.
Messy field sheets, KoBo or ODK exports turned into one analysis-ready table — de-duplicated, validated, geocoded to union or upazila, with a log of every change made.
Journal-ready maps and figures at the size, resolution and colour rules the journal asks for — including the accessible palettes reviewers increasingly require.
The free builder, with me doing the work: your material rewritten, laid out and delivered as PDF and an editable file.
One session on your CV, your portfolio and the two or three projects worth building next — from someone who hires and reviews in this field.
Describe the problem in a few lines — the data you have, what you need at the end, and when. I will tell you whether it is a small job, a project, or something you can do yourself with the free tools.
Fulbright, Commonwealth, Chevening, DAAD, Erasmus+, Australia Awards, MEXT, KGSP, Türkiye Bursları and the Bangladeshi government stipends in one board — opening date, closing date, what each one wants, and what you already have ready in My documents. It tells you what is missing three weeks before the deadline, not three days.
The MPhil/PhD proposal and the donor concept note are the same eight blocks in a different order: problem, gap, question, objectives, method, data, timeline, budget. Build them once, print either shape, and export the Gantt chart with it.
Everything a journal asks for besides the manuscript: the cover letter to the editor, the title page with author order and ORCIDs, highlights, the author-contribution (CRediT) statement, the conflict-of-interest and data-availability lines, and the suggested reviewers. One form, then the files in the shapes each publisher wants.
Upload your thesis and it is read against your own university's rules — margins, font and size, line spacing, chapter and heading numbering, figure and table captions, the order of the front matter, and whether every figure is actually cited in the text. A list of page numbers to fix, not a grade.
The monitoring report an NGO actually files: photos with their coordinates and timestamps, laid out beside a location map that places each one, with the observation under it. Drop the phone photos in and the map draws itself from the EXIF.
An invoice a Bangladeshi bank will accept for an inward remittance — invoice number, service description, the currency and the rate, your e-TIN, and the declaration the encashment certificate needs. With a plain one-page contract for the work it covers.
The logical framework every donor form asks for — goal, outcome, output, activity, each with its indicator, means of verification and assumption — and the workplan and budget table that have to agree with it. Change an activity and the three stay in step.
For one union or upazila: how often it has flooded since 2016 from Sentinel-1, how much of the settlement area sits inside that, where the shelters are and how long it takes to walk to them. A six-page sheet with the maps, the numbers and the method — the thing a UP chairman, an NGO proposal or a thesis chapter can all cite.
What a place was and what it became, between any two years back to 1990, with the classification accuracy stated honestly and the confusion matrix printed. For a mouza, a khal, a char, an industrial belt or a protected forest edge.
The questionnaire built in KoboToolbox, the sampling frame worked out and defended, the enumerator manual, the consent script in Bangla, and the data-quality checks that catch a bad interview the same evening rather than at analysis.
Your routine data — monthly returns, field submissions, a sensor feed — on one page that updates itself, with the map, the trend and the table a manager actually opens. Built on the same stack as this site, handed over with the code and a page explaining how to change it.
No trial, no watermark, no export limit, no upsell. The only thing asked of you is a free account when you download, so the file has an owner and your work can be saved. If a tool here is ever going to cost money, this page will say so before you start typing.
The editor, the preview and the PDF are all made by your own browser — the file is never built on, or stored on, the server. What you press সংরক্ষণ on is kept in your account so you can open it again from another device; until then nothing has left this browser.
Institution, roll, session and supervisor carry across the tools — the next one you open offers to fill itself in, and every document can hand its details to the cover-page maker.
The university list is a convenience. If yours is missing, one click switches to manual entry and the finished page is identical.
If your university, department or subject is missing, the report button inside the cover-page tool sends it straight to me and it is added from the admin — usually the same day. Subject codes change with the curriculum year, so check a listed one against your own course outline before you rely on it.
